How to make a simple greenhouse from window frames. DIY greenhouses from old window frames

Ready-made greenhouses made from cellular polycarbonate and perfect aluminum profiles, they certainly look great. But their price is so high that even the most economical gardener may completely lose the desire to acquire such a miracle. And everyone who does their best builds their own greenhouses and greenhouses literally from scrap materials - it’s not beautiful, but it’s practically free and very practical. And in this regard, those who often visit the city are especially lucky: today the fashion for plastic windows is simply at its peak, and orderly rows of old and quite decent wooden frames, even with intact glass, appear near landfills every day. It’s enough to just go with a trailer to such places twice – and that’s it: building a greenhouse from window frames is not difficult. All that remains is to understand the intricacies of making a small foundation and erecting a frame - and you can assemble your greenhouse-architectural tetris from window frames of different sizes. And self-tapping screws and connecting compounds will be used: silicone sealant, cement and construction foam.

Stage I. Making the right foundation

If the greenhouse made from window frames will be located on clayey or swampy soil, it is necessary to make a cushion of gravel in advance, on top of which a layer of sand 10-15 cm high should be poured. After all, greenhouses and even a small greenhouse made from window frames are the heaviest, and they can easily sag on unstable soil. That is why it would be advisable to install pillars made of stone, brick, or even make them concrete at the corners of the greenhouse. In general, experienced experts advise starting the construction of a greenhouse from window frames only with the construction of the foundation - even if the future greenhouse will be located on “normal” soil.

So, a good foundation for a greenhouse can be a strip, 10x10 cm timber and sleepers.

How to make a foundation from timber

First, you should remove the entire fertile layer of soil and compact the next layer of soil if it turns out to be loose. Next, all work should be carried out according to the following algorithm:

1. A layer of sand or crushed stone is laid and filled with cement mortar to a depth of 15 cm.
2. You need to lay bricks or stones on the resulting “cushion” and fill it with cement mortar again.
3. A new layer of stones or bricks is laid so that they completely cover the seams of the bottom row.
4. On top of everything you need to lay 2 layers of waterproofing roofing material.

How to make a strip foundation

It is better to build a greenhouse from window frames on a solid strip foundation. In its manufacture, you should also remove the top fertile layer of soil and dig a trench. If the soil under the top layer turns out to be weak and crumbling, then formwork will be necessary, but in a denser one you can do without it. And making formwork is not difficult - just put old boards along the walls of the trench and cover them with film to prevent concrete from adhering to them.

There is another way - a rubble concrete strip foundation. To do this, you need to lay large stones at the bottom of the dug trench and fill the space between them with smaller ones or crushed stone. Then fill everything with concrete and repeat the whole procedure again.

Stage II. Preparation of building material

Window frames must be prepared before installation. All hinges, handles and latches must be removed. It is generally advisable to remove old paint and treat exposed wood with a special antiseptic.

If during the work the frames will be attached to the frame with nails, then it is better to remove the glass first and carefully position it. After all, on the glass itself there may be microcracks invisible to the eye, which from the vibrations of a hammer can easily turn into large cracks. But those windows that will not be used in the greenhouse should be sealed, carefully sealing all the cracks - after all, you can make a greenhouse from window frames without any windows at all, like.

Stage III. Laying the floor in a greenhouse

For the floor in the greenhouse, you need to dig a space at least 15 cm deep. The entire base should ultimately be well leveled and compacted. You can pour concrete into the floor directly over this compacted earth for extra strength.

So, it is necessary to pour fine gravel onto the prepared base, in a layer about 10 cm thick. Next, the gravel is covered with plastic or roofing felt - this will be an excellent barrier to dampness and undesirable growth of weeds underfoot. On top of everything you need to pour 5-10 cm of good construction sand and compact it again. To ensure that the floor in the greenhouse is compacted well, you can use a vibrating plate. And finally, it is better to lay the bricks closer together on the floor and fill them with construction sand so that all the cracks are filled.

Stage IV. Construction of frame and roof

The basis for a greenhouse made from window frames can be a frame made of boards of the same thickness as the window frames - 4-5 cm. In general, the frame will consist of a top and bottom trim plus racks. It is more expedient to make the bottom trim from two boards, because The height of window frames usually does not exceed 160 cm. The long sides of the frames will be located on the racks, due to which the gaps between them will be covered. It is advisable to attach the frames to the racks themselves with self-tapping screws, and to strengthen the frames in the frame, you can nail support bars to the inside of the racks. Moreover, the support bars can be safely made from boards of a slightly smaller cross-section.

In those parts of the greenhouse where there are not enough frames, polycarbonate sheets can be used. Best roof for a greenhouse made of window frames - gable and completely covered with polycarbonate. If a greenhouse is being built, then the roof can be made from them.

The height of the walls of such a greenhouse should be at least 170-180 cm. But the height of the greenhouse itself will depend on the angle of inclination of the roof slopes, which in turn is determined by the material used - for film it should be larger so that it does not sag, for polycarbonate - less. To prevent the film on the roof of the greenhouse from sagging at all, you can pre-stretch a nylon cord under it - a fine mesh, or initially purchase a reinforced film.

In order to build walls from window frames, you must first install vertical supports at the base. Using D-shaped notches in the cement, they need to be fixed, and wooden strips create a plane for installing the walls. The wooden sticks themselves should be nailed to the supports. And in order for the greenhouse roof to have the slope necessary for drainage, it is better to trim the upper edges of the supports.

Regardless of how exactly the old windows will be attached to the frame - with large screws or nails - between the frames themselves, it is imperative to seal all the cracks with polyurethane foam. Only then will a homemade greenhouse made from old window frames be truly reliable and durable.

Once the frame for the walls is ready, it's time to move on to the roof - nailing the strips in the same way. The roof of such a greenhouse can be made into a traditional gable roof, especially if old windows are used for its manufacture, or a single-pitch roof. The second option is much more economical and easier, and in winter the light film roof can be removed completely if the greenhouse is used in very coldy If it doesn’t, then there won’t be any risk of a collapse due to a ton of snow.

Now you can nail the windows themselves to the frame. If nails are used, it is advisable to nail them in as often as possible to make the walls strong.

But the roof can be covered with film, polycarbonate, and partially with windows - but not completely, otherwise it will be difficult to avoid overheating in the greenhouse later. Of course, a greenhouse made from photo window frames is far from being as beautiful as those made from expensive polycarbonate, but in terms of functionality and durability it is in many ways superior to any semi-plastic structure.

Spacious, "growth" greenhouse for growing early vegetables and seedlings is the dream of every gardener. Unfortunately, most often this desire does not coincide with the financial capabilities of the owners suburban areas - high prices on factory products, as well as the cost of building materials, can cool the ardor of even the most avid summer residents. To avoid unnecessary expenses and get a reliable and durable structure, just pay attention to the old window frames - perfect solution for making a greenhouse with your own hands.

Window frames as a building material: pros and cons

What home craftsmen come up with, breathing a second life into seemingly useless and unnecessary things. Today it is impossible to say who first came up with the idea of ​​building a greenhouse from used window frames, but the genius and simplicity of this solution deserves respect and admiration. Old windows are practically ideal option, because they have a number of advantages over other building materials:

• tightness ensured design features frame;
• high degree of light transmission due to large area glazing;
• mechanical strength;
• rigidity;
• the presence of vents for ventilation;
• installation speed;
• the possibility of building a greenhouse without the involvement of assistants;
• ease of repair in case of damage;
• low cost.

The demand for plastic windows simplifies the search for material for building a greenhouse

Although the use of window frames has so many undeniable advantages, this material should not be idealized. The weight of a wooden frame is, in fact, small, but when assembled with glass, the structure becomes heavy and requires a solid foundation - otherwise, ground movement can cause the structure to shift and damage the glass. Over time, the junctions between separate elements dry out and require sealing, and the wood itself needs protection from the harmful effects of a warm and humid environment, so you need to be prepared for small repair work at the beginning of each season. However, these shortcomings are not so significant as to refuse such a simple and accessible way construction.

Design and design features

Like other similar structures, a greenhouse made from old windows is installed on a solid wooden or concrete base. The choice of foundation depends entirely on the frequency of use of the structure, the structure of the soil, the topography of the site and other natural factors. On durable earthen soils as support, it is enough to use 50-60 mm thick boards made of hard wood, while sandy or sandy loam soil, as well as the danger of flooding with groundwater, will require thorough concrete work.

In some cases, a solid concrete base is indispensable

Of course, individual window frames can be attached directly to each other, but in order to obtain a strong, reliable structure, you must first assemble a frame from wooden slats with a cross-section of at least 50x30 mm. This solution will significantly increase the rigidity of the structure, which means that the risk of damage to windows when frames are deformed during installation and during operation will be reduced. Another factor in favor wooden frame is the ease of installation of doors and a significant simplification of the roof structure, so it is not worth giving up a strong frame in order to save money - in the future this decision will justify itself many times over.

Greenhouse frame construction from used windows

Some home craftsmen also use window frames as roofing material, arguing that the light transmission of the greenhouse increases and the structure becomes truly monolithic. However, this is not recommended for several reasons:

• moisture flowing into cracks and gaps between the glass provokes increased rotting of the wood;
• possibility of roof damage from hail;
• low structural stability under snow load;
• an increase in roof mass reduces the stability of the greenhouse;
• It is impossible to predict how old window frames will behave over time, so such a roof is considered potentially dangerous.

At the same time, for the construction of not a greenhouse, but a greenhouse, the use of window frames as roofing material is more convenient and practical.

One of the greenhouse options for a suburban area

An important issue that should be decided at the design stage is the type of roof. Gable or arched structures, although more complex, resist winter drifts very well - snow rolls perfectly along their inclined surfaces. Concerning pitched roof, then it is much easier to install and requires less building materials, but you will have to pay for it by reducing the reliability of the structure.

An arched roof copes best with snow and rain

To connect individual frames and building elements to each other, you can use furniture corners and metal strips, which are fastened with self-tapping screws. Of course, preference should be given to parts made of galvanized metal - we should not forget about high humidity, which provokes rapid corrosion of fasteners.

Corners and metal perforated strips from the nearest building materials store are suitable for attaching window frames.

Most likely, the frames intended for the construction of a greenhouse will differ in size. To simplify the work, you will need to take the dimensions of the windows and number them, and then make a small sketch indicating the sizes and installation locations of individual mounting blocks. Of course, it is better to use windows of the same height - in this case it will be easier to install them, and the greenhouse will turn out not only even and symmetrical, but also beautiful.

When drawing up a working drawing, be sure to take into account the recommended sizes of beds and passages between them

The length of the structure can be any - it all depends on personal preferences, availability of space and building materials. But when calculating the width, it is necessary to take into account the location and number of beds, as well as the paths between them. To make it convenient to work in the greenhouse, its passages are taken equal to 0.5 m - this will allow you to move around with a small wheelbarrow. The width of the beds must be at least 1 m, otherwise the plants will not have enough space for normal growth.

Tip: a larger greenhouse can be built from the same amount of material if it is built as an extension to one of the outbuildings located on the site.

Getting ready for construction

At the very first stage, a place for a greenhouse is selected, the site is cleared, and building materials and tools are prepared.

Choosing a place

The success of the entire event depends on how correctly the location for future construction is chosen. Firstly, the structure should be illuminated by sunlight for as long as possible, so shaded areas near tall buildings or trees should not be considered. Secondly, it is better to install the greenhouse in places with minimal movement of atmospheric layers - a decrease in wind load affects the stability of the structure and reduces heat losses. Thirdly, the fertility and condition of the soil must be taken into account. On bulk and unstable soils, it will be necessary to build a columnar or strip foundation, otherwise the walls will warp and the glass in the frames will crack.

The construction site should not be located in lowlands. Even if it is possible to avoid flooding or silting of the beds, then the plants will have a high level of groundwater will have a detrimental effect.

Before starting to arrange the foundation for a greenhouse, stumps are removed at the construction site, the area is cleared of debris, and cleared of weeds and bushes.

Scheme for choosing a location for installing a greenhouse or greenhouse

What you need to build a greenhouse

Depending on the chosen greenhouse design, in addition to the window frames themselves, the following materials will be needed for construction:

• roofing felt;
• sand and crushed stone;
• cement;
• steel pipes with a diameter of at least 100 mm;
• hardwood boards 50–60 mm thick;
• timber 50x50 mm;
• slats 20x40 mm;
• metal corners;
• self-tapping screws;
• polyurethane foam;
• polyethylene film or polycarbonate sheets;
• protective and antiseptic agents for wood processing.

You can’t do without polyurethane foam when building a greenhouse from window frames - it reliably seals all joints and gaps

It is better to prepare the tools in advance, otherwise the process of pleasant creation may turn into a tedious search. Here's what you might need while working:

• an angle grinder (“grinder”) with a cutting disc for working on metal;
• sledgehammer;
• shovel and bayonet;
• containers or stretchers for carrying bulk materials;
• wood hacksaw;
• a set of screwdrivers or a screwdriver;
• hammer;
• drill with a set of drills for wood and metal;
• roulette;
• building level;
• pencil.

If you plan to install the greenhouse on a solid foundation, then you should take care in advance about how the concrete solution will be prepared - you will need a metal vat or a concrete mixer.

Preparing window frames

To build a spacious greenhouse you will need a lot of window frames, so it is better to look for materials for construction in advance. Of course, you can ask friends and acquaintances about their availability, but it is best to look through newspapers for free advertisements or contact one of the installation companies plastic double glazed windows- there you can buy old windows for a nominal fee.

You can use a hair dryer to remove old paint.

Before starting construction, future wall panels should be prepared. This will increase their service life and make the structure more attractive. To tidy up old window frames, you need to:

• dismantle fasteners and fittings (handles, latches, latches, hinges, etc.);
• Use a sander or scrapers to remove any remaining old paint. In some cases, you can use a special remover, for example, the compositions “Antikras-Sprint”, “Zebra SP-6”, “Household” and others;
• treat the frames with antiseptic agents that can protect the wood from fungi and insects;
• Secure unused windows with self-tapping screws. Gaps on mating surfaces should be repaired using sealant or putty.

Some online resources suggest exposing glass from frames, arguing that it may be damaged during installation. We do not recommend doing this under any circumstances. Most likely, the glass will require replacement just after unsuccessful dismantling, especially if during its installation wooden glazing beads were used, mounted on ordinary enamel or oil paint.

Step-by-step instructions for building a lean-to greenhouse from window frames with your own hands (without a foundation)

We offer you an algorithm for building a spacious greenhouse from old window frames. Its installation does not require a solid concrete foundation, so installation can be completed within two weekends. The structure has a pitched roof and is distinguished by its simple and undemanding design - any home craftsman can replicate it.

Base installation

A properly arranged wooden base will last at least 10 years only if the certain conditions for his protection. Otherwise, the wood will rot much faster - a humid environment and contact with soil do not contribute to the safety of the boards.

So, you will need a beam with a cross-section of at least 100x100 mm made of larch, oak, acacia and other sustainable types of wood. It must be treated in several layers antiseptics, then tar it.

The place where the base will be laid must be prepared in advance. To do this, a trench up to 20 cm deep is dug along the perimeter of the structure, in which a sand and crushed stone cushion is installed. The drainage layer will remove excess moisture and promote durability wooden base. To achieve its maximum durability, the trench is covered with a layer of roofing felt and only after that the timber is laid.

The wooden base of the greenhouse is protected from moisture in any available way.

The individual elements are attached end to end using metal strips and corners, as well as using the “half-tree” method. To do this, indentations are made on the mating parts using a saw, hammer and chisel, after which they are connected to each other using nails or self-tapping screws. As a rule, additional fastening of the base to the ground is not required - the mass of the window frames will be enough for the structure to successfully withstand the wind. However, for reliability, pipe sections 0.5–0.6 m long can be driven into the ground from the inside of each corner, attaching them to the beam using metal strips.

One of the ways to attach a wooden greenhouse base

For significant differences in elevation, as well as in lowlands, use columnar foundation. It is equipped using metal pipes large diameter or by pouring concrete blocks. The boards laid on such posts are secured with dowels or metal corners, and the gap between the base and the surface of the area is covered with clay and carefully compacted.

Walling

The assembly of the greenhouse begins with the construction of the frame. To do this, a lower frame made of timber is laid on the base. You can use any type of lumber, it is important that their cross-section approximately matches the thickness of the frames. Most often, they take inexpensive pine beams with a cross-section of 50x50 mm, the individual elements of which are fastened with furniture corners or the “half-tree” method.

The frame of the greenhouse made of window frames includes vertical posts and horizontal lower and upper trim

Vertical posts are installed at the corners of the frame, as well as every 2–3 m (the distance depends on the width of the window frames). Their length is chosen taking into account the height of the windows, as well as focusing on one’s own height - it must be comfortable in the greenhouse, otherwise work “for the soul” will turn into punishment. The greenhouse has a pitched roof, so the posts on one side should be 0.5–1 m higher - this will provide the roof with the required slope.

For a small greenhouse, vertical posts installed at the corners of the structure will be sufficient.

At one end of the greenhouse, vertical posts are installed so that the resulting opening can serve as a door frame. Perhaps the width of the structure will not be enough to cover the remaining space with window frames. In this case, the space between the door and the corner posts is covered with plastic film.

From above, the vertical structural elements are connected to each other by horizontal strapping using the same screws and metal corners. Unlike greenhouses covered with plastic film, structures with walls made of windows do not require reinforcement of the frame. The structure will acquire the necessary rigidity after the wooden frames are installed in place. However, there is no need to rush to install them - you should first make the roof.

Frame assembly

Roof arrangement

Device pitched roof for capital structures is shown in the figure. In our case, there is no need to install additional racks and rafter legs - they, like ceiling beams, will be needed only in greenhouses more than 6 meters wide. In the greenhouse under consideration, the roof support in the lower part is the upper frame frame, so all that is needed is to attach the timber to the ends of the long posts and install the rafters. The best material for them is not timber, but a board installed “on edge” measuring 50x100 mm. It will not allow the roof to sag even with a significant snow load.

Shed roof design

If the greenhouse will be covered with film, then the rafters should be sanded and then covered with fabric or foam rubber. They will save roofing material from damage.

The rafter legs are mounted to the horizontal frame in the places where the racks are installed, at a distance of no more than 1 m from each other. To fasten polycarbonate sheets perpendicular to the rafters, 20 mm thick slats can be laid, while polyethylene film does not require additional lathing.

One of the mounting methods rafter leg

We have already said above that it is not recommended to use window frames as a roof - film or polycarbonate is much safer, and they are also easier to install. When choosing polyethylene fabric, preference is given to heat-stabilized materials - they are practically not susceptible to the destructive effects of ultraviolet radiation. The best option is considered to be a special reinforced film for greenhouses. As a rule, such coverage is enough for 2-3 seasons.

It is convenient to use thin slats or window beads to attach the film.

Mount roll material with a little tension, so this work is best done together with a partner. To attach the film, wooden planks are used - they provide sufficient pressure and prevent damage to the polyethylene. An overlap is made on both sides of the greenhouse, which will be sufficient to eliminate the gaps between the frame framing and the longitudinal beams of the roof. The gable openings are also covered with polyethylene or triangular polycarbonate panels. By the way, the latter option is more preferable due to its durability - it will not be necessary to renew the coating for many years.

Fixing window frames and installing doors

After constructing the frame and roof, they begin to install the window frames, checking with the previously developed drawing. Windows are installed with outside frame, after which they are fixed to the beams and to each other using nails, self-tapping screws, furniture corners and perforated metal strips. During installation, the frames are oriented so that the windows open outward. Excessive vibration that occurs during nailing of frames to the frame threatens to crack the glass. To reduce shock load, V in the right places perform through drilling. Their diameter should be 0.5–1 mm smaller than that of the nails used - a slight tension will only benefit the connections.

The gaps between the individual elements of the greenhouse are filled with polyurethane foam. After hardening, excess polyurethane sealant is cut off flush with the frames, and then plastered or covered with thin wooden strips. This will protect the sealing layer from the harmful effects of ultraviolet radiation and excess moisture.

A greenhouse made from old window frames is ready for use.

The door frame is made of wooden beams and attached to the frame using conventional metal hinges in such a way that the door opens towards you when visiting the greenhouse. Considering the increased operational load, it is better to sew up the sashes not with film, but with a polycarbonate sheet. When building a large greenhouse, you can use ready-made balcony door. Of course, in this case doorjamb must be reinforced, so it is made from a 50x100 mm board with a selected quarter.

Latch bolts and stops are mounted on the door and vents, which will allow them to be held in place. open position for ventilation internal space.

The success of a greenhouse mini-farm will depend both on the quality of the structure itself and on its internal filling. A properly equipped greenhouse will make it possible to work easily and comfortably, while maintaining a positive mood. And this, as you know, is half the success in any business.

One of the most important stages When building a greenhouse, the construction of beds is necessary. If the site is located on fertile soil and is not subject to flooding, then it is enough to install fences and pour a mixture of humus, peat and black soil inside. If there is a danger of flooding, as well as in places with high level groundwater, paths and beds are made only after drainage is installed on the floor.

Arranging beds in a greenhouse

For these purposes, soil is removed to a depth of 20 cm, after which the floor is covered with a 10-centimeter layer of fine crushed stone or granite screenings. The remaining space is filled with sand and compacted thoroughly. After this, the beds are formed, installing border tape or strips along their perimeter flat slate, creating frames from boards or doing brickwork. The internal space is filled with a fertile mixture. Its thickness should be sufficient to grow the selected garden crops, therefore this parameter is not standardized. For some, a layer of 20–30 cm is enough, while others prefer not to bend over, creating so-called raised beds up to 70–90 cm high.

The paths inside the greenhouse can be covered with crushed stone or sawdust - this will effectively remove moisture. The disadvantage of such a coating is that it creates difficulties when moving greenhouse equipment and complicates cleaning. It is best to spend a little money and lay out the paths with paving slabs, concrete or make a boardwalk. In the latter case, oak logs and hardwood boards are used. Before laying, the supporting elements of the structure must be tarred, and the platform itself must be treated with an antiseptic and coated with oil paint.

In a properly equipped greenhouse, work is a pleasure

So that the greenhouse is not only a functional unit, but also has a complete appearance, all wooden parts should be painted inside and out. This will not only make the structure more attractive, but will also make it more durable.

Video: features of building a greenhouse from old windows

Building a greenhouse from old window frames is not difficult at all. For this you will not need any expensive materials, nor a specific tool - only your desire and imagination. By equipping it with a drip irrigation system, installing heating and lighting, you can achieve excellent results in growing early garden crops and get fresh vegetables on the table at any time of the year.

The process of mass replacement by the population of old wooden windows freeing up a large number of window frames for fashionable double-glazed windows. Old wooden window frames in good condition, often with intact glass and working seals, are almost always scrapped. There are more rational uses for the material. If you manage to collect one and a half to two dozen wooden boxes, then it is quite possible to build a greenhouse with your own hands from window frames, the construction of which will cost several times less than the classic version made from corrugated pipe.

Requirements for the condition of window frames

To make even a small greenhouse, you can use almost any type of window frame, especially since the choice of material for construction is not particularly large; most often, what is on hand or managed to be exchanged with neighbors is used.

Minimum requirements for material for wooden greenhouse, come down to two points:

• The wood of window frames must be solid, without cracks or signs of rotting of the material due to fungus or natural wear;
• The window frame should not have deformations, deviations from the plane, “propeller” twists or distortions.

To build a greenhouse from old window frames with your own hands, even boxes with cracked glass, provided that the cracks do not pose a risk of destruction of the glass sheet. Before making a greenhouse from window frames, the cracks are sealed with tape or silicate glue, and the peeling paint is cleaned off with a brush and a sharp knife. The dried surface of the wooden parts of window frames is painted with white enamel and dried in the sun.

Where to get old window frames

One of the problems that one has to face when planning a greenhouse remains the task of selecting material. For a small greenhouse you will need 15-16 single frames measuring 100x110 cm; for a full greenhouse measuring 8x3.5 m you will need to prepare 30-35 pieces of old window frames. There are several options to obtain the specified amount of materials:

• Buy materials from pensioners who ordered the installation of new double-glazed windows;
• Agree with workers involved in the installation of metal-plastic windows for individuals;
• Buy frames for greenhouses from municipal or school institutions.

Typically, mass replacement of windows in institutions is associated with the accumulation of large quantity old frames, doors, window sills, everything that can serve as an excellent building material for building a greenhouse. Most often, managers themselves are interested in getting rid of garbage as quickly as possible, and will be glad to receive any help.

We build a greenhouse from old frames

Despite the fact that the window frame looks quite strong and durable, it must be used very carefully as a building material; any vertical or shear load, for example, from gusts of wind or snow cover on the roof of a greenhouse, can lead to cracking and destruction of the glass.

Therefore, when planning greenhouses from window frames, two simple construction principles are followed:

• Initially, a frame is assembled from a wooden beam and a metal corner, as is done for all frame buildings, which include greenhouses;
• Old window frames are inserted inside the frame, which are fastened together with steel plates and self-tapping screws.

Important! As a result, the entire load, including the weight of the window frames themselves, falls on the frame base of the greenhouse. This type of construction allows you to replace or remove any of the frames without the risk of destroying the entire greenhouse.

For the same reason, summer residents prefer to make a glass roof for a greenhouse from lightweight polycarbonate or tighten it with ordinary plastic film. If the plans for building a greenhouse include making a glass roof from window frames, then the weight of the very heavy transparent roof must be compensated with the help of struts, approximately as in the photo, and the frame itself must be made from the frames as an extension to the house.

Arrangement of the foundation for the greenhouse and the first tier of piping

The location for the greenhouse made from window frames is chosen on the sunny side of the site on the leeward side. The top layer of soil along the contour of the future building is removed and replaced with a mixture of crushed stone and sand. The weight of the greenhouse is small, so a pile-column option can be used as a foundation, as it is the simplest and cheapest. In the corners and at the middle points of the rectangular base, pine pillars 20-25 cm in diameter are driven into the ground, which will simultaneously serve as supports for the roof. The supports are driven into the ground to a depth of 70-80 cm, leaving 180-200 cm above the soil. All six pillars are tied along the upper level with timber with a section of 90x70 mm, and you can begin installing window frames.

The greenhouse frame is assembled in the following order:

For your information! The use of wooden poles and piles will require very high-quality wood treatment with antiseptic and bitumen coatings.

The remaining three long and two side spans are assembled in a similar way. The pillars and the lower tier of the framing are painted and covered with a vapor barrier film. To prevent the wind from tearing the insulation, the material is attached to the window frames of the greenhouse using wooden strips and staples or air nails.

An air gap of 20-25 cm high remains between the lower beam on which the window frames rest and the ground. It is usually used as vents and ventilation of the interior space of the greenhouse. When growing certain varieties of some in a greenhouse heat-loving crops, for example, tomatoes or eggplants, ground ventilation is required, therefore, in addition to the vents and transoms available in the window frames, the basement of the greenhouse walls is covered with folding panels made of boards lined with polyethylene.

Roof and additional parts of the greenhouse

The size of the greenhouse frame and the low strength of the walls made of window frames do not make it possible to make a glass roof. Alternatively, you can use cellular polycarbonate or polyethylene. The easiest way to make a roof for a greenhouse is according to the classic gable scheme.

The length of the greenhouse is quite large, eight meters, so to fix the ridge beam you will need to make and install three additional supports from profiled pipe. First of all, roof gables are installed on the walls of window frames, between which a marking cord is pulled. But the tension markings are set by T-shaped metal supports and the central girder of the beam. To prevent the knocked-down boards of the roof ridge from falling before the rafters are installed, the racks are temporarily sewn to the trim and window frames using a slab.

The easiest way to make a ridge beam is from three sections of 2.7 m each; the individual parts are connected to each other by bolts with metal plates 4 mm thick and 40-50 cm long. Other methods of splicing a ridge for a greenhouse are unsuitable; any fasteners using screws or nails the season is practically coming to an end.

After assembling the ridge strip, you need to assemble the rafter system. The rafters can be cut from slabs or timber; you only need the help of an additional worker to cut the required angle for support on the walls made of window frames.

In order to lay polycarbonate on the roof of the greenhouse, in addition to the rafters, you will need to sew a batten in increments of no more than 40 cm. This is one of the best roofing options for a regular greenhouse. To build from window frames, there is no particular need to use such expensive material.

Moreover, due to the fact that walls made of window frames have 40% higher light transmission, the roof of the greenhouse can be made translucent. On the one hand, this will reduce the thermal pressure when there is excess sunlight, on the other hand, it will allow serious savings on materials. Instead of a polycarbonate roof that costs several hundred dollars, building a roof on polyethylene or agrotextile is much cheaper.

To install a film roof on the rafters, it will be enough to stretch steel wire - wire rod and glue polyethylene using construction tape.

Small greenhouse option

There are no rules without exceptions, all of the above applies to full-size greenhouses and greenhouses. A small greenhouse of 10-12 m2 can be assembled by simply connecting several frames using an upper timber frame. To prevent the walls from moving apart under their own weight, the window frames are installed on a foundation made of wooden piles.

On pile foundation the harness is mounted from steel profile, on which walls from old window frames are exposed. Instead of metal, you can use oak timber impregnated oil impregnation for protection against moisture.

The third power element that holds the window blocks together into one frame is four pairs wooden rafters made of 70x50 mm timber, connected into rigid triangles. The rafter frame must be reinforced with cross members made of boards or timber.

In the corners of the top timber frame, triangular horizontal struts are additionally installed, which gives additional rigidity to the entire greenhouse frame. The result is a fairly strong frameless structure that does not require external struts or a heavy concrete foundation.

For the roof, you can use polyethylene in early spring or agrotextile fabric, which protects greenhouse plants from sunburn.

Conclusion

Greenhouses made from old window frames have one significant drawback. After several decades of service, the wood of a window block becomes covered with a network of tiny cracks. Therefore, every year the window frames will need to be painted. weatherproof enamels and seal the cracks with foam. In this case, the lower edge of the window frame is filled with mastic waterproofing. Any attempt to lay a brick or block foundation under window blocks will require the installation of very serious waterproofing and the installation of protective cladding made of PVC panels.

Only financial resources and thinking allow a summer resident to create certain structures on his site. After all, as a rule, at the dacha we try to create everything with our own hands. Today we can talk about creating structures such as greenhouses, and they will be made from old window frames. This is the most budget option of all the possible ones that can exist. And you don’t have to look for materials, since old windows can be found everywhere.

Where can I get window frames? It’s very simple: windows in a neighboring house or even an apartment, in a kindergarten, or in a school can be changed. Don't waste your chance: you need to take the frames to your garage. At the same time, you will even be grateful that construction waste (such as frames) will be removed from the site.

But just the availability of building materials will not solve the problem. You need to know how to properly make a greenhouse from frames for your greenhouse farm.

DIY greenhouses from old window frames

It is worth noting that a foundation must be laid for the greenhouse. Without it, the structure will collapse. The weight of the frames will be so great that over time the greenhouse will simply sag.

The highest quality and most reliable material is brick. However, the material is quite expensive. But with long-term use it pays off perfectly. Excessive moisture may cause the stone to deteriorate.

Natural stone is also expensive, but will be able to withstand the strongest greenhouse structures. Natural stone can also withstand the most humid environments, which makes it possible to give advantages in use to this particular material.

Wooden foundation

Wood is also a very durable material, but after five years you will have to replace the wooden foundation, which will begin to crumble under the influence of moisture and temperature changes.

Experts say that the best option is concrete. Such a foundation can last as long as possible. Of course, you can use absolutely any construction option. It all depends on what financial resources you have.

Frame of the structure

It is worth noting that the greenhouse itself, made from window frames, is already quite durable. You just need to strengthen it and mount it correctly. In order for the frame to be strong, it must be firmly strengthened with the base. Window frames are simply connected to each other on the base using corners, screws, studs and other fastening materials. Each person determines for himself what materials to use for fastening. It all depends on the budget.

So, let's look at the most common types of frame fastenings

Corners and screws are rightfully the most reliable. During the installation of the greenhouse, you will only need to properly install the greenhouse and secure it to the foundation. The parts of the greenhouse are secured with corners and then connected to each other with self-tapping screws. This way it is possible to achieve the maximum degree of stability.

You can also install the greenhouse using wood nails as well as beams. This option is even simpler than the previous method of connecting structures. Inside, the frames are connected using small cross-section beams.

There is another way that requires a minimum of time and effort. To do this you will need wire and clamps. Using the wire, you can wind it around the part of the connection and tighten it with pliers. Plastic clamps, which can be bought at a hardware store, are also used for tension.

Installation of a greenhouse from old windows

It must be said that any greenhouse structure can be created from the frames. The only thing is that you need to assemble everything correctly so that the structure lasts a long time. In order for the work to be completed efficiently, all work must be carried out step by step.

The frame and base are the most important parts of the greenhouse during installation. The fasteners must be strong and reliable so that the greenhouse lasts a long time. There may be connections that require welding.

How to cover a greenhouse from frames

Since the frames themselves are heavy, it is not recommended to use glass. In this case, the weight will increase even more. Glass is used when a small greenhouse is being assembled. The best option is to cover the greenhouse with plastic film. For this, a simple sheathing is used on the top of the structure. Once the film is placed over the top of the greenhouse, you can begin to stretch the film.

Once all work is completed, you need to check its quality. If no flaws are found, then you can begin planting various crops. Now on your plot at any time of the year you can plant various crops that can only be grown on the plot.

Greenhouse in temperate climate– construction required at any dacha. Sudden spring cold snaps and frosts near the ground surface destroy plants planted in open ground, but a greenhouse allows them to be grown starting in early spring.

And since few people want to spend money on complex designs and expensive materials, there is always a temptation make a greenhouse from scrap materials, one of which is window frames. If you or someone you know is replacing windows, this is a good chance to acquire cheap material for building a greenhouse.

Wooden and plastic frames: pros and cons

We are building a greenhouse with our own hands from old window frames: which frames to choose - wooden or plastic?

Window frames have undoubted advantages compared to other materials. First of all, this strength of window frames.

A wooden frame will have to be built in any case, but the frames fastened together will take part of the mechanical load on themselves, and the resulting structure will be stronger than wire arches or pine poles, from which greenhouse frames are most often made ( but no stronger than factory galvanized steel frames).

Additional advantage appears at such a greenhouse, if the windows can open. In this way it is very easy to regulate the temperature inside in late spring and summer, when on a sunny day in a closed greenhouse the temperature can reach a disastrous 60 degrees.

Opening and closing the necessary windows, you can adjust the temperature even in separate parts of the greenhouse, if it is large enough.

Double glass provides good thermal insulation in the absence of cracks through which heat could escape and cold winds could blow in.

Another plus - durability. Glass does not decompose in the sun like plastic film, and if for some reason it breaks, it is easy to replace, especially for wooden frames.

Finally, price. If you change the windows yourself, then you get the material for the greenhouse for free, if your friend changes them, he can sell the material he doesn’t need for next to nothing.

Disadvantage is less strength compared to metal frames, vulnerability to the effects of putrefactive fungi that decompose wood and various insect pests. This makes a greenhouse out of wooden frames short-lived.

A greenhouse made from window frames has its advantages and disadvantages, but if building a greenhouse is necessary, try it, do it yourself.

Plastic windows for greenhouses

As a rule, plastic windows have double-glazed windows, which allows them to provide more reliable thermal insulation than wooden frames with single panes of glass.

Positive aspects double glazing is strength(and structural rigidity), as well as resistance to negative environmental factors. They do not swell or dry out due to changes in humidity, like wood, and do not rot. Therefore, they do not need to be treated with antiseptics or painted.

Disadvantages of plastic windows are their heavy weight, inaccessibility and difficulty in repair(glass in a wooden frame can be replaced or you can simply fill the frame with film if the glass breaks and the double-glazed window has to be completely replaced).

Preparatory work

How to build a greenhouse from old window frames with your own hands, how to choose a location, what kind of foundation to make? Let's try to answer these questions.

Selecting a location

When choosing a location for a greenhouse, a summer resident usually has little choice. The main thing that the place was not shaded from the south, southeast and southwest. Particularly detrimental for greenhouse plants is the proximity to walnut, because this tree not only casts a shadow, but also releases phytoncides that inhibit the growth of all other plants.

Trees can be dangerous also because during a storm heavy dry branches break off from them, which can damage or destroy the greenhouse.

It is also desirable that the building was protected from the wind, which can destroy it.

The soil under the structure must be level, motionless and dry.. It is desirable that it be sandy soil. If the soil is clayey, you should fill it with gravel, pour sand on top and apply a fertile layer.

You can read more about the rules for locating greenhouses on the site by following the link.

Preparation of the project and drawing

When designing a greenhouse, it is important to consider the following points:

• ratio of window frame sizes to the height you need(it is desirable that the height of the walls is not lower than 180 cm), if it is not possible to stack the frames one on top of the other, you will have to build up the walls from below using other materials;
• roof: most likely, you will have to use a beam or a metal roof frame for it, since winter time may accumulate on the roof up to several tons of snow;
• the roof ridge needs to be oriented along the north-south axis to ensure proper lighting in the greenhouse.

If according to calculations it turns out that there are not enough window frames, You can use polycarbonate sheets instead appropriate size.

If the greenhouse will be heated by a stove, immediately think about where the smoke will come out. Chimney can come out both through the wall and through the roof, but if it is made of metal, it will become very hot, and therefore should not come into contact with either polyethylene or polycarbonate.

It is advisable to provide a special window for it (you can also use an existing window), and the space between round pipe and cover the square window frame, for example, with tin or plywood.

Foundation

Unlike conventional greenhouses made of wooden or steel frames and plastic film, greenhouses made of window frames foundation is needed. This is due to the fact that the frames are too heavy, and the soil under them will sag unevenly if you build a greenhouse without a foundation.

What materials can be used to create such a frame? It turns out there are quite a lot of options:

In areas where there are severe frosts, the foundation should reach maximum depth of ground freezing. Also use thermal insulation, for example, foam.

Step by step: building a greenhouse

How to prepare frames?

Before you start building walls, frames should be prepared. First of all, you should remove all metal parts such as hinges, awnings, latches and protruding nails. Then the frames are cleaned of old paint using metal brushes.

After this the tree is necessary etch with an antiseptic so that bacteria and fungi do not destroy it too quickly. Fortunately, the choice of antiseptics today is quite wide. After this you can additionally paint the frames, but the antiseptic itself provides sufficient protection against fungi, insects, rodents and moisture.

If you decide to nail the frames, glass must be removed during installation, if with screws, then you don’t have to do this.

Frame

How to build a greenhouse from old window frames with your own hands: photos and drawings will help us see this more clearly and build our own version of a greenhouse from wooden or plastic windows. To build the frame use timber 50X50 mm or a board 40 mm thick. The frame consists of racks, upper and lower frames. The latter should be made of identical boards and increase the height of the walls of the greenhouse. The racks should be spaced at such a distance from each other that the window frame fits strictly between them, and they, in turn, cover the gaps between two adjacent frames.

For real The roof frame must be strong. It is best for the roof to be gable, with additional supports under the ridge, otherwise it may collapse under the weight of the snow. Therefore, complete the roof frame best made from timber.

Rice. 4. Diagram of the structure of the frame and the placement of window frames on it.

Assembly

Installation can be done with both nails and screws. Screws hold more firmly, but are more expensive. Each frame is secured both externally and internally, on each of its four sides. Then the gaps between the frames are sealed with polyurethane foam.

Installation of a greenhouse from plastic windows will have to be done using bolts and nuts, drilling holes for them.

Roof

It is not advisable to use windows for the roof. Instead, you can stretch plastic film or use polycarbonate. Fully a transparent roof means it will be too hot inside in warm months, therefore it must be sprinkled with a chalk suspension (as for whitewash) to create a slight shadow. The light that penetrates through the walls is enough for photosynthesis. The film is attached using slats.

Doors

It is advisable to do them two at the ends of the greenhouse so that if ventilation is necessary, a draft can be created. The easiest way is to put together their frames from boards and cover them with plastic film, nailing it to the tree using thin slats.

Rice. 5. The role of the door is played by the opening window.

Conclusion

Thus, window frames are cheap and convenient material for self-construction greenhouses. The advantages of such a greenhouse are the availability of materials, ease of installation and operation, and the disadvantages are the need for a foundation and lower strength compared to a steel frame.

Useful video

Some more information about homemade greenhouses from window frames can be seen in the video.

Frames should not disappear - they can always be used for useful purposes!

In this article I will tell you how to build a greenhouse from window frames. This task is quite labor-intensive, especially if we want to get not a temporary greenhouse, but a permanent structure, but the result is worth it. Reuse using old frames makes it possible to significantly save on greenhouse glazing, so it’s definitely worth the tinkering.

Such structures can be erected according to a variety of schemes, so here I will describe general principles buildings tested in practice. Having figured out what's what, you can make adjustments to the algorithm I proposed in accordance with your wishes for the final result.

Preparatory work

Stage 1. Foundation

A greenhouse from window frames is assembled according to the principle of a designer, and the most difficult moment here will be finding the frames themselves. As a rule, construction begins after overhaul country house when several windows appear after replacement.

After all, it’s a shame to throw it away, but I want to attach it to some business. But, alas, for a fairly large structure this quantity is not enough, so you have to go to your neighbors and beg, barter or buy unnecessary windows.

That's what we need!

Usually for the construction of structures closed ground standard wooden structures are used, and that is what I will talk about in the article. It is also possible to build greenhouses and greenhouses from PVC windows, but this is quite an expensive pleasure, and therefore this layout option is practically not found.

Be that as it may, let’s assume that we have the required number of glazed frames. Now we have to somehow install them on the soil.

And here we need to lay at least some foundation: without a foundation, only a very small greenhouse can be built, since a capital structure will inevitably sag under its own weight.

Beam base on brick pillars

There are several options for arranging the base for a greenhouse made of frames, and I will describe them in the table below:

Material	Peculiarities
Tree	The easiest way to give the greenhouse the required shape and evenly distribute the load on the soil is to install it on a base made of wooden beams. A frame made of thick, mastic-impregnated timber is laid on the surface or slightly recessed, and a frame for glazing is formed on it. The performance properties of such a base are satisfactory, but over time, even wood treated with a moisture-proofing compound loses its strength. So the replacement of beams (and therefore the complete reconstruction of the greenhouse) must be carried out at least once every 5 - 7 years.
Brick	A columnar or strip brick base is a good option in terms of strength and durability. Brickwork, folded according to all the rules, can withstand significant loads, in addition, it also serves as additional thermal insulation in the soil layer of the greenhouse. The downside is the high cost of high-quality building stone - however, in order to save money, you can also use used bricks.
Concrete	A strip concrete foundation or a columnar structure made of concrete blocks is an ideal foundation for a permanent greenhouse. A concrete strip or blocks reinforced with steel bars can withstand significant loads, while waterproofing underground parts roofing felt or mastic effectively protects concrete from destruction under the influence of moisture. The disadvantages of this solution include the significant labor intensity of the arrangement and serious financial costs.

Having decided to make such a greenhouse with my own hands, I settled on a combined option:

Before you make a greenhouse from window frames, you need to pour something like this foundation

1. First, a layer was removed from the area fertile soil to a depth of about 30 cm. I folded the soil separately and then used it to form beds.
2. On the leveled area, I marked the foundation of the future greenhouse and dug trenches 50 cm deep and 40 cm wide.
3. Sand was poured into a 10 cm layer at the bottom of each trench and the cushion was carefully compacted.
4. I installed formwork from old boards, lined it with thick polyethylene and poured strip base made of concrete. Instead of reinforcement with a steel bar, I added broken stone to the solution.
5. After the initial polymerization of the concrete, the formwork was removed and the foundation was covered with polyethylene to prevent drying out.

Beam over concrete base

1. After 25 days (normally you need to wait 28 - 30 days, but I just couldn’t wait), I removed the polyethylene and mounted it on concrete base strapping made of timber with a cross-section of 150 mm. I placed two layers of roofing felt under the timber for waterproofing.
2. At the corners I connected the beams into half a tree and secured them to the concrete with anchors. The wooden parts themselves were treated with a moisture-proofing compound.

Naturally, this scheme is not the only possible one. Moreover, it is quite labor-intensive, so for simpler greenhouses you can use either only timber frames or only concrete tape.

Stage 2. Frame installation

A homemade greenhouse made from window frames is usually assembled on a frame. It consists of an upper and lower harness connected vertical posts on the corners.

If the walls of the greenhouse are of considerable length (4 m or more), it is worth strengthening the frame with additional vertical supports.

Fastening the stand to the dowel

1. In my case, the role of the bottom frame was a beam laid on a concrete foundation. On the sides I lined it with boards so that they protrude above the beam by at least 100 mm.

Fastening racks with cutting or with an overlay

1. At the corners I installed racks made of timber with a section of 50x50 mm. I fixed the supports with self-tapping screws, pulling them to the boards of the lower frame.
2. I made the top trim from the same timber, securing it to supports.

I needed a small greenhouse, so I did not install additional supports and reinforcing crossbars. If you need a large structure, then you should draw all the necessary drawings and see where it will be possible to strengthen the structure with racks, struts, etc.

Approximate frame diagram

Stage 3. Roofing

Much more often the roof is covered either cellular polycarbonate, or plastic film - this way the load on the rafter system will be significantly lower.

Gable option

It was the last option that I chose:

1. I cut rafters from a 100x25 mm board. At the bottom of each rafter leg I made a recess for the upper trim.
2. I connected the rafters in pairs, and then fastened them to the ridge beam.
3. I attached a frame for an opening window to the rafters.
4. With the help of two helpers, the resulting roof frame was lifted onto the frame of the greenhouse, installed on the top frame and secured to the rafters with metal overhead plates.

Such reinforced film suitable for roofing

1. I covered the top of the roof with a light-stabilized film (both slopes and gables), leaving only the opening for the window open.

The disadvantage of a woven roof is obvious: the film is not mechanically durable, and it is almost guaranteed that it will have to be replaced in two to three years.

On the other hand, the costs of arranging the roof will be minimal, and the lower (compared to glass or polycarbonate) transparency of polyethylene is compensated by additional lighting penetrating through the walls from the window frames.

Greenhouse assembly

Stage 4. Installation of frames

Now our construction is approaching its final stages: we need to install window frames, hang doors and vents, and also furnish the room from the inside.

Installing frames on a corner

Let's start the description with the installation of frames:

1. Old window frames must be prepared before installation on the frame. This preparation consists of dismantling hinges and locking elements, eliminating the most obvious damage, replacing broken glass, etc.

It is worth replacing the glass after installation is completed: this way there is less risk of breaking a new window during installation.

1. We begin to mount the products from the corner. We place the first window near the vertical support on the lower beam, level it and fix it to the frame using metal plates.
2. We install the following structures with minimal gaps, connecting them with steel plates on self-tapping screws.

We connect the frames with plates on self-tapping screws

1. If the greenhouse (what if you are so lucky!) is assembled from plastic windows, then join individual designs It is best to use a balcony connector. It is inexpensive, attaches simply (the protrusions snap into the grooves of adjacent frames), but it provides a very strong fixation.
2. After installing all the frames, fill the gaps between them with foam.
3. From the outside, fill each crack with a thin wooden plank– it will not only help minimize heat loss, but also serve as an additional stiffener.

The photo shows that the gaps are sealed with polyurethane foam

Everything is clear with the first row of frames, but the height of the structure will be no more than 1400 - 1600 mm. If you want to make the greenhouse taller, then the distance between the top edge of the row of installed frames and top harness It is best to cover it with film.

I would not install a second row of frames (even if laying them on their sides) - the base becomes too unstable.

Stage 5. Doors and vents

It is not enough to build a greenhouse - you need to equip it in such a way as to provide an optimal microclimate for the plants. And if in terms of heat everything depends on the tightness of the housing, then you need to think about ventilation separately.

Door to ensure inflow fresh air plays virtually no role in the greenhouse premises. That is why I use the simplest design on a wooden frame covered with several layers of polyethylene. I fix it on regular hinges and equip it with a simple lock that holds the door leaf closed.

Door on a timber frame

It is much more important that the greenhouse has efficiently functioning vents. It would seem that the answer to the question of how to make a window in a greenhouse is extremely simple - take and use any of the windows on the frames that now make up the walls.

But the fact is that such windows will have to be opened and closed independently, depending on the temperature inside the greenhouse - and this is quite troublesome, and there is always a risk of missing the right moment.

An automatic window that opens and closes depending on the temperature does not have these disadvantages. The easiest way is to equip it with a special hydraulic cylinder, but the price of such a device may seem too high to many.

Therefore, in this section I will tell you how to make a structure with similar functionality with your own hands from improvised means:

Hydraulic cylinder for greenhouse

1. I take a ready-made small sash or make it from profiled timber. I install axial hinges on the frame - so that the sash rotates around a horizontal axis, and in the vertical (or inclined, if we are making the structure on one of the roof slopes) position it is completely closed.
2. I attach the window to the bottom crossbar from the outside wooden block– it will act as a load for automatic closing.
3. I fill the jar with liquid (I use antifreeze, but you can also use water) about 40% and seal it tightly. I install a thin tube into the lid.
4. I securely secure the container with antifreeze and pipe under the ridge of the greenhouse.
5. I also close the second jar (smaller volume) with a lid with a tube. I make a hole with a diameter of 3 mm in the lid for air access. I fill the jar with antifreeze so that the bottom edge of the tube is immersed by about 10-12 mm.
6. I drive a long nail into the top crossbar of the opening window frame, from which I securely hang a small can.
7. I connect both containers with a flexible hose.

Homemade automatic window: 1) counterweight; 2) frame; 3) limiter; 4) suspension for smaller capacity

Self-opening windows in a greenhouse work according to the following scheme:

1. As the temperature rises, the liquid from the upper container will evaporate and flow through the hose into the lower container. Besides. Increased pressure will play a role when antifreeze expands.
2. Due to this, the weight acting on the upper crossbar of the window will increase, and the window will open, letting in fresh air.
3. As the temperature decreases, there will be reverse process: the liquid will be drawn into the upper (sealed) container, and the window will close under its own weight.

Before making such a design the basis of the entire ventilation system, it needs to be configured by selecting the optimal volumes of liquid for reliable operation of the system.

Actually, the arrangement of the greenhouse does not end there: you need to lay the beds inside, lay paths, if this is provided for in the project, install lighting and additional heating. But in any case, the design turns out to be quite reliable and functional!

Conclusion

A do-it-yourself greenhouse from old window frames can be created even by gardeners who have not previously been involved in construction and design. Its design is quite simple, and therefore, after reading the recommendations in the text and studying the video in this article, you can assemble this structure quickly and at relatively low cost.

If this idea interests you, then all questions you may have can be asked in the comments below: if I can, I will definitely recommend something useful!

If you want to express gratitude, add a clarification or objection, or ask the author something - add a comment or say thank you!

Far-sighted owners, in order to grow early greens and vegetables, are thinking about how to equip greenhouses. To do this, the most inventive and economical of them choose from a large number of building materials those that literally lie under their feet. One of the options for available materials used to build a greenhouse with your own hands is old window frames.

Alternative methods for constructing greenhouses

The simplest type of greenhouse is a cover greenhouse. It is a polyethylene film that covers the frame structure.

Practical

To create a frame you will need a material that has a certain strength and flexibility. This can be large diameter wire, pipes or any other material that has the appropriate properties. The frame, constructed by bending blanks, is covered with polyethylene, the edges of which are fixed to the ground with a board and covered with earth.

To implement another version of a similar structure, you will need an old pallet and boards covered with film. This design has compact dimensions. It is placed near the wall of the building, which is located on the sunny side. In this case, the calculation is that at night heat will be transferred from the wall to the greenhouse.

Using polypropylene pipe and films, you can create a more reliable and practical greenhouse. To assemble it, you need pipes and corners made of polypropylene. The frame of the required size is obtained by installing the pipe structure to the corners by welding and gluing. Polypropylene is easy to process, so you can easily assemble a greenhouse of the desired size.

Greenhouse made of polypropylene pipe and film

If you use a large diameter pipe, the film can be replaced with sheet polycarbonate. If you stiffen the entire structure with special ribs, you will get a reliable and durable greenhouse.

The large number of used plastic bottles gave impetus to engineering. To build a greenhouse from such material, a considerable amount of such empty containers will be required. A wire or strong thread is pulled in two rows on the mounted frame. Between them, bottles are installed in the form of columns, the bottom of which has been previously removed. For greater tightness of the structure, bottles should be installed with maximum density.

Greenhouse made from bottles

However, with all the advantages of the described designs, do-it-yourself greenhouses made from window frames are leaders in popularity and their qualities.

How to supply construction with materials?

The seemingly insoluble question of providing a construction site with a sufficient supply of old window frames has a simple answer. Moreover, the scale of the problem is exaggerated, since the dimensions of the greenhouse will not require many window designs. The massive transition of residents from wooden frames to modern double-glazed windows determines the availability of the required material close to the house. If it is not possible to find old window frames, you can seek help from specialists who install double-glazed windows. Most often, used frames are unclaimed.

Old window frames

The process of building a greenhouse from window frames

Site selection

The choice of construction site depends on the following factors:

• how well the area is lit;
• is there a shadow from other structures that are of great height;
• how protected the site is from wind;
• location relative to cardinal directions.

The choice of greenhouse dimensions is influenced by:

• dimensions of the plot;
• type of crops and their quantity;
• dimensions of window frames.

Greenhouse made of frames

An important factor is the characteristics of the soil. It is undesirable to build a building on swampy or very wet soil, as the risk of subsidence of the structure increases. For reliable installation of a greenhouse, dry soil with sufficient density is best suited. In addition, the availability of groundwater significantly influences the choice of construction site. Minimum depth their occurrence should be at least one and a half meters.

In this case, it is important to provide an appropriate height of the room, which allows for work to be carried out in the greenhouse. Having determined the approximate dimensions of the building, a selection of old window structures is made, which makes it possible to clarify the length of the structure.

At the end, a plan diagram is drawn up and the width of the structure is calculated, taking into account the location of the beds and paths that you wish.

Foundation or base

Due to the fact that the structure has a certain mass, the organization of the base for it is necessary step. In order to prevent subsidence or destruction of the greenhouse, as well as to give it strength and reliability, it is installed on a foundation.

Available various options foundation organization:

• Brick. It is characterized by reliability, but at the same time relatively high cost. At correct installation has sufficient durability. However, when exposed to moisture and temperature changes, it is prone to destruction.
• Stone. It is highly expensive, but at the same time extremely reliable. Can withstand the load of a larger structure. Impact resistant external factors and has a long service life.
• Wood. A foundation made of such material has acceptable strength and stability, but does not have a long service life. Durability does not exceed 5-8 years. It should be understood that the window frames themselves will most likely not last much longer.
• Concrete. Device strip foundation is optimal in terms of durability, performance characteristics and cost of construction.

The foundation is the basis of the greenhouse

Preparatory work with frames

Before you build a greenhouse from window frames with your own hands, to simplify the assembly of the structure, as well as increase its strength characteristics, you should carry out preparatory activities. Parts of the frames may become unusable, so they must be dismantled or replaced. Preparation includes:

• removal of fittings;
• removing old paint;
• antiseptic treatment;
• dismantling glazing in the presence of chips and other defects;
• fixing vents that will not be used.

The preparation and layout of the frames must take into account that the greenhouse must have a height of at least 1.7 m.

Floor installation

When arranging the floor, it is important to pre-organize drainage in order to prevent flooding of the structure and premature failure of its elements. For this purpose, it is necessary to dig a trench 150 mm deep, and create a cushion of sand and gravel at the bottom. If the floor is made of concrete, it is necessary to create a slope with a slight angle, and also provide a hole for draining water.

The correct organization of the internal space of a greenhouse is of great practical and certain aesthetic importance. It is advisable to fence the passages with curbs, which can be made of wood or plastic. This will prevent the soil from shifting into the passage.

In addition to concrete, the following can be used to organize paths inside the greenhouse:

• sawdust. They absorb moisture, create conditions for comfortable movement of a person, but impede the movement of equipment. The use of sawdust leads to clogging of the greenhouse area;
• ceramic tile. As a rule, significant We correctly design the paths inside the greenhouse

  the cost of the material does not imply its use in budget designs. But in the case where there is a residue or broken tile after repairs, it can be used to create a practical floor;

• tree. To create a floor, beams are laid along the greenhouse, to which planks are mounted in the transverse direction. Such flooring should be subjected to antiseptic treatment to increase the service life of the structure;
• brick. Bricks are laid on a sand bed. After this, wet sand is poured into the gaps between them and compacted. This design has long term operation and practical to use.

Making the right frame

To create a greenhouse from frames, it is better to use boards as a frame. Their thickness should be approximately the same as the frames and be 40-50 mm. The boards are connected in such a way that the structure is a strapping. The strapping should be at the top and bottom, while it is desirable that the bottom be made up of two rows of boards.

Correct frame

Walling

Installation of vertical posts will create the volume of the structure. The frames are attached to the racks along the long side. Existing gaps must be sealed using construction foam. To create a more rigid structure, the frames are fastened from the inside with bars that serve as support.

The cross-section of these parts may be smaller than that of the material of the main elements.

Vertical supports, which are recommended to be installed when constructing the frame, give greater stability to the structure. They are fixed using cement or by fastening them with nails to the posts.

To avoid drafts, be sure to ensure that all cracks are eliminated. The exception is vents intended for ventilation.

Supports

Roof structure

Before you make a greenhouse from old window frames, you need to decide on the type of roof. The roof can be made with one or two slopes. To a certain extent, the choice depends on the number of available structural elements. If their number is limited, you can decide to build a pitched roof, the slope of which should facilitate the unhindered drainage of precipitation.

At equal conditions device gable roof is preferable. Pre-prepared and processed frame blanks are placed on the top frame and nailed to them. After this, a ridge is constructed from wood or plastic. It is important that the joints are as tight as possible. The occurrence of leaks leads to disruption of the microclimate in the greenhouse and contributes to the development of mold.

If there is a shortage of frame blanks, you can use sheet polycarbonate or thick film specifically designed for the construction of greenhouses.

In this article I will tell you how to build a greenhouse from window frames. This task is quite labor-intensive, especially if we want to get not a temporary greenhouse, but a permanent structure, but the result is worth it. Reusing old frames makes it possible to save a lot on greenhouse glazing, so it's definitely worth the tinkering.

Such structures can be erected according to a variety of schemes, so here I will describe the general principles of construction, tested in practice. Having figured out what's what, you can make adjustments to the algorithm I proposed in accordance with your wishes for the final result.

Preparatory work

Stage 1. Foundation

A greenhouse from window frames is assembled according to the principle of a designer, and the most difficult moment here will be finding the frames themselves. As a rule, construction begins after a major renovation of a country house, when several windows appear after replacement.

After all, it’s a shame to throw it away, but I want to attach it to some business. But, alas, for a fairly large structure this quantity is not enough, so you have to go to your neighbors and beg, barter or buy unnecessary windows.

Typically, standard wooden structures are used for the construction of closed ground structures, and it is these that I will talk about in the article. It is also possible to build greenhouses and greenhouses from PVC windows, but this is quite an expensive pleasure, and therefore this layout option is practically not found.

Be that as it may, let’s assume that we have the required number of glazed frames. Now we have to somehow install them on the soil.

And here we need to lay at least some foundation: without a foundation, only a very small greenhouse can be built, since a capital structure will inevitably sag under its own weight.

There are several options for arranging the base for a greenhouse made of frames, and I will describe them in the table below:

Material	Peculiarities
Tree	The easiest way to give the greenhouse the required shape and evenly distribute the load on the ground is to install it on a base made of wooden beams. A frame made of thick, mastic-impregnated timber is laid on the surface or slightly recessed, and a frame for glazing is formed on it. The performance properties of such a base are satisfactory, but over time, even wood treated with a moisture-proofing compound loses its strength. So the replacement of beams (and therefore the complete reconstruction of the greenhouse) must be carried out at least once every 5 - 7 years.
Brick	A columnar or strip brick base is a good option in terms of strength and durability. Brickwork, laid according to all the rules, can withstand significant loads, in addition, it also serves as additional thermal insulation in the soil layer of the greenhouse. The downside is the high cost of high-quality building stone - however, in order to save money, you can also use used bricks.
Concrete	A strip concrete foundation or a columnar structure made of concrete blocks is an ideal foundation for a permanent greenhouse. A concrete strip or blocks reinforced with steel rods can withstand significant loads, while waterproofing underground parts with roofing felt or mastic effectively protects concrete from destruction under the influence of moisture. The disadvantages of this solution include the significant labor intensity of the arrangement and serious financial costs.

Having decided to make such a greenhouse with my own hands, I settled on a combined option:

1. First, I removed a layer of fertile soil from the site to a depth of about 30 cm. I folded the soil separately and then used it to form beds.
2. On the leveled area, I marked the foundation of the future greenhouse and dug trenches 50 cm deep and 40 cm wide.
3. Sand was poured into a 10 cm layer at the bottom of each trench and the cushion was carefully compacted.
4. I installed formwork from old boards, lined it with thick polyethylene and poured a strip base of concrete. Instead of reinforcement with a steel bar, I added broken stone to the solution.
5. After the initial polymerization of the concrete, the formwork was removed and the foundation was covered with polyethylene to prevent drying out.

1. After 25 days (normally you need to wait 28 - 30 days, but I almost couldn’t wait), I removed the polyethylene and mounted a frame made of timber with a cross-section of 150 mm on a concrete base. I placed two layers of roofing felt under the timber for waterproofing.
2. At the corners I connected the beams into half a tree and secured them to the concrete with anchors. The wooden parts themselves were treated with a moisture-proofing compound.

Naturally, this scheme is not the only possible one. Moreover, it is quite labor-intensive, so for simpler greenhouses you can use either only timber frames or only concrete tape.

Stage 2. Frame installation

A homemade greenhouse made from window frames is usually assembled on a frame. It consists of an upper and lower frame connected by vertical posts at the corners.

If the walls of the greenhouse are of considerable length (4 m or more), it is worth strengthening the frame with additional vertical supports.

1. In my case, the role of the bottom frame was a beam laid on a concrete foundation. On the sides I lined it with boards so that they protrude above the beam by at least 100 mm.

1. At the corners I installed racks made of timber with a section of 50x50 mm. I fixed the supports with self-tapping screws, pulling them to the boards of the lower frame.
2. I made the top trim from the same timber, securing it to supports.

I needed a small greenhouse, so I did not install additional supports and reinforcing crossbars. If you need a large structure, then you should draw all the necessary drawings and see where it will be possible to strengthen the structure with racks, struts, etc.

Stage 3. Roofing

More often, the roof is covered with either cellular polycarbonate or polyethylene film - this way the load on the rafter system will be significantly lower.

It was the last option that I chose:

1. I cut rafters from a 100x25 mm board. At the bottom of each rafter leg I made a recess for the upper trim.
2. I connected the rafters in pairs, and then fastened them to the ridge beam.
3. I attached a frame for an opening window to the rafters.
4. With the help of two helpers, the resulting roof frame was lifted onto the frame of the greenhouse, installed on the top frame and secured to the rafters with metal overhead plates.

1. I covered the top of the roof with a light-stabilized film (both slopes and gables), leaving only the opening for the window open.

The disadvantage of a woven roof is obvious: the film is not mechanically durable, and it is almost guaranteed that it will have to be replaced in two to three years.

On the other hand, the costs of arranging the roof will be minimal, and the lower (compared to glass or polycarbonate) transparency of polyethylene is compensated by additional lighting penetrating through the walls from the window frames.

Greenhouse assembly

Stage 4. Installation of frames

Now our construction is approaching its final stages: we need to install window frames, hang doors and vents, and also furnish the room from the inside.

Let's start the description with the installation of frames:

1. Old window frames must be prepared before installation on the frame. This preparation consists of dismantling hinges and locking elements, eliminating the most obvious damage, replacing broken glass, etc.

It is worth replacing the glass after installation is completed: this way there is less risk of breaking a new window during installation.

1. We begin to mount the products from the corner. We place the first window near the vertical support on the bottom one, align it and fix it to the frame using metal plates.
2. We install the following structures with minimal gaps, connecting them with steel plates on self-tapping screws.

1. If the greenhouse (what if you are so lucky!) is assembled from plastic windows, then it is best to join the individual structures using a balcony connector. It is inexpensive, attaches simply (the protrusions snap into the grooves of adjacent frames), but it provides a very strong fixation.
2. After installing all the frames, fill the gaps between them with foam.
3. On the outside, we fill each crack with a thin wooden plank - it will not only help minimize heat loss, but also serve as an additional stiffening rib.

Everything is clear with the first row of frames, but the height of the structure will be no more than 1400 - 1600 mm. If you want to make the greenhouse higher, then it is best to cover the distance between the upper edge of the row of installed frames and the top trim with film.

I would not install a second row of frames (even if laying them on their sides) - the base becomes too unstable.

Stage 5. Doors and vents

It is not enough to build a greenhouse - you need to equip it in such a way as to provide an optimal microclimate for the plants. And if in terms of heat everything depends on the tightness of the housing, then you need to think about ventilation separately.

The door plays virtually no role in ensuring the flow of fresh air into the greenhouse room. That is why I use the simplest design on a wooden frame covered with several layers of polyethylene. I fix it on regular hinges and equip it with a simple lock that holds the door leaf closed.

It is much more important that the greenhouse has efficiently functioning vents. It would seem that the answer to the question of how to make a window in a greenhouse is extremely simple - take and use any of the windows on the frames that now make up the walls.

But the fact is that such windows will have to be opened and closed independently, depending on the temperature inside the greenhouse - and this is quite troublesome, and there is always a risk of missing the right moment.

An automatic window that opens and closes depending on the temperature does not have these disadvantages. The easiest way is to equip it with a special hydraulic cylinder, but the price of such a device may seem too high to many.

Therefore, in this section I will tell you how to make a structure with similar functionality with your own hands from improvised means:

1. I take a ready-made small sash or make it from profiled timber. I install axial hinges on the frame - so that the sash rotates around a horizontal axis, and in the vertical (or inclined, if we are making the structure on one of the roof slopes) position it is completely closed.
2. From the outside, I attach a wooden block to the bottom crossbar of the window - it will act as a weight for automatic closing.
3. I fill the jar with liquid (I use antifreeze, but you can also use water) about 40% and seal it tightly. I install a thin tube into the lid.
4. I securely secure the container with antifreeze and pipe under the ridge of the greenhouse.
5. I also close the second jar (smaller volume) with a lid with a tube. I make a hole with a diameter of 3 mm in the lid for air access. I fill the jar with antifreeze so that the bottom edge of the tube is immersed by about 10-12 mm.
6. I drive a long nail into the top crossbar of the opening window frame, from which I securely hang a small can.
7. I connect both containers with a flexible hose.

Self-opening windows in a greenhouse work according to the following scheme:

1. As the temperature rises, the liquid from the upper container will evaporate and flow through the hose into the lower container. Besides. Increased pressure will play a role when antifreeze expands.
2. Due to this, the weight acting on the upper crossbar of the window will increase, and the window will open, letting in fresh air.
3. As the temperature drops, the reverse process will occur: the liquid will be drawn into the upper (sealed) container, and the window will close under its own weight.

Before making such a design the basis of the entire ventilation system, it must be configured by selecting the optimal volumes of liquid for reliable operation of the system.

Actually, the arrangement of the greenhouse does not end there: you need to lay the beds inside, lay paths, and if this is provided for in the project, install additional heating. But in any case, the design turns out to be quite reliable and functional!

Conclusion

A do-it-yourself greenhouse from old window frames can be created even by gardeners who have not previously been involved in construction and design. Its design is quite simple, and therefore, after reading the recommendations in the text and studying the video in this article, you can assemble this structure quickly and at relatively low cost.
