Installing a blind plastic window with your own hands. Installing a plastic window with your own hands: let's look at installing a plastic window step by step

Plastic windows have become so popular not only because of their operational and technical characteristics, but also due to their simple installation process. Even at home, without special construction skills, installing plastic windows with your own hands is quite feasible, due to the fact that the factory kit includes additional parts for fasteners, and the installation rules are simple.

In order to install plastic windows with your own hands, it is enough to follow the recommendations of specialists, be patient and invite a reliable person as an assistant.

Window measurements and calculations made before purchasing

Before buying a plastic window, you should take the most careful measurements of the window opening.. In this case, it is necessary to take into account the presence or absence of a quarter in it. This feature will play an important role in calculating heat loss, and therefore in the consumption of material for window production. The fact is that quarter openings are usually used in buildings made of foam concrete; they significantly reduce thermal energy losses. If the window opening is without a quarter, the window should be smaller than the opening by 5 cm in length and 3 cm in width. As a result, you will get gaps along the contour that will be foamed, 1.5 cm at the top, right and left, and 3.5 cm at the bottom, where you will install the window sill. According to GOST, the gaps around the perimeter can be 2.0 cm. Thanks to this, finishing the opening before installing plastic windows is greatly simplified.

When calculating the size of a window for an opening with a quarter, the measurement at the narrowest point is taken as a basis, and 3 cm is added to the width. The length is not taken into account.

The plastic window should be positioned inside the opening 1/3 deep relative to the plane of the outer side. However, for those who want to do this work with their own hands, this condition is not important: you can make a shift in any direction. The main thing is to take this circumstance into account in the calculations prior to installation, and when ordering window sills with external ebbs, add 5 cm to the width of these elements for each.

Before installing anchor plates in the opening, make small recesses for them. This will save you from having to level the surface before you begin installing the internal slopes.

Often, when installing a structure, specialists use these two methods, combining them with each other. To do this, the anchors are buried inside the wall through the base and sides of the frame, when the top is secured with plates.

Standards for installing plastic windows

When installing a metal-plastic structure in a window opening with your own hands, a prerequisite is the use of polyurethane foam. This material will give the frame-opening connection the necessary rigidity, provide additional fastening and act as an insulator. To prevent the layer of polyurethane foam from losing its technical capabilities over time, insulating strips are glued onto it: on the outside - with a waterproofing effect, on the inside - with a vapor barrier. Since wood has the ability to transmit steam, it is recommended to lay foil insulation around the perimeter of the wooden box.

The time of year in which the installation of plastic windows will be carried out is chosen by the owner. Experts often recommend doing it yourself in winter: this allows you to immediately identify possible flaws. When choosing polyurethane foam, pay special attention to the instructions. In it you will find data on the temperature values ​​at which the composition will harden faster, as well as a description of how to properly foam. Usually this process is performed from the bottom up, blowing the foam several times in small sections of 25 cm - this will help to avoid unnecessary consumption of material, which is not cheap.

Preparing the window opening before installing the structure

Installing plastic windows yourself implies complete cleanliness of the prepared surface. That is, the opening from the inside must be free of paint residues, dust or debris. If a plastic window is mounted in a frame made of wood that has already been used, the outer layer should be planed off, or completely eliminated if you think that it may peel off after the mounting foam dries.

Pay attention to the size of the gaps between the opening and the frame. If they are more than 4 cm, then filling them only with foam will not only be very expensive, but also of poor quality. In such cases, it is better to use scraps of timber, foam plastic or drywall for partial filling.

Preparing a plastic window for installation

To begin with, the frame should be freed from the doors by carefully removing the pin located in the upper hinge. To do this, use a screwdriver and pliers; these are the most suitable tools for DIY work. Then remove the sash from the lower hinge, lifting it slightly. If the window is solid, the glass unit is removed from it by first removing the longitudinal and then the transverse beads. To remove the bead, take a putty knife, insert it into the gap, and move it slowly to avoid damaging the glass surface.

A small plastic window can be installed without removing the double-glazed windows. To do this, it is enough to use mounting plates.

Place the removed structural elements on a surface previously covered with a soft, thick cloth or cardboard, leaning against the wall at a slight angle. Do not lay the glass unit flat. Any, even the smallest, obstacle under the base can subsequently lead to the formation of cracks in the glass unit, bending of slopes and other defects.

Now remove the layer of protective film from the frame. It is recommended to do this right away, otherwise you will have to face certain difficulties later.

Mark the places for fastenings in increments of no more than 40 cm, departing from the impost and corners by 15 cm. When using mounting plates, first secure them with self-tapping screws on the surface of the frame.

Installing a plastic window in the prepared opening

Self-installation and fastening of plastic windows with your own hands requires attention and accuracy. Therefore, follow it step by step, strictly adhering to the recommendations.

Along the perimeter of the opening, lay spacers - bars or plastic corners, which will provide a technological gap. Insert the frame, strictly aligning it horizontally and vertically, making sure that the side gaps are even. In order to control the position of the frame, use a plumb line and a spirit level.

Once there is no doubt about the correct installation of the frame, proceed to fastening it.

If the walls of the house are built of wood, screw (not all the way) screws through the holes located in the frame.

Before attaching the frame to a concrete or brick wall, you should mark the points for fastening through the holes on the surface of the frame, remove the frame and use a drill to make recesses into which the fasteners will be attached.

In case of installation using anchor plates, bend them so that they fit snugly against the anchor point. The finishing of the slopes following the installation of PVC windows will require precision.

Complete the final fastening of the window: carefully screw in the screws, making sure that the cap does not protrude more than 1 mm above the level of the double-glazed window frame.

Insert all the dismantled elements in reverse order, check how fully the structure as a whole functions.

Fill any gaps left and cover the seams with protective tape on the outside and inside.

The space under the drainage system for slopes should also be filled with foam. Attach it to the bottom profile of the frame with self-tapping screws, inclined relative to the surface of the window. This finish will prevent rattling during rain.

After the polyurethane foam has polymerized, install the window sill, placing it 2 cm under the sweet clover. Foam the space under it, this will provide a slight slope.

Immediately, or within a maximum of three days after installing the plastic windows, install the slopes.

Before you begin work such as finishing slopes with plastic, stock up on the following:

• a strip of plastic material about 10 mm thick;
• U-shaped profile, which will serve as a starting profile;
• F-shaped profile;
• wooden slats 10-15 mm thick and 40-50 mm wide;
• soft texture insulation.

Finishing of slopes is carried out as follows.

Using self-tapping screws, attach the starting profile along the outer edge of the frame. There should be no gaps at the junction of the internal walls at the point of vertical and horizontal connection of the starting profile. Then mount the rail around the perimeter of the opening: it should not protrude beyond the surface of the wall.

The F-shaped profile is made of a plastic strip and stapled to the edge of the rail closest to the wall. The slope panel will be inserted into the groove.

An acrylic sealant is placed inside the plastic profile and a pre-prepared panel is inserted. The gap is evenly filled with insulating material. The outer remainder of the workpiece is inserted into the F-shaped profile. The blanks are mounted on the sides of the frame in the same way. After installing the panels, the overlaps are carefully cut out. The joints are degreased and filled with liquid plastic. Carefully remove any excess. This completes the work of finishing the slopes with plastic.

When all work on installing a plastic window is completed, it is not recommended to use the structure for 16 hours, so that the seams remaining after installation dry out and do not lose their integrity, and the cladding is not damaged.

As you can see, installing plastic windows and finishing slopes yourself is a task that is feasible even for a beginner. These recommendations will help you not only do all the work yourself, but also control the process of installing plastic windows if you decide to use the services of an installation team.

Nowadays, most residents of apartment buildings already have plastic windows; few can argue with the advantages of their energy and heat saving, and also sound insulation. Thus, plastic windows have almost completely replaced their predecessors. At the same time, there are some points when installing windows that neutralize their main advantages. In order to install a plastic window, you need to follow several basic rules. But first things first.

Preparation for dismantling

Before you are going to install a window in your house or apartment yourself, you need to make sure that you have all the necessary tools for measuring, dismantling and installing plastic. Although the installation of plastic windows does not require special skills, do not neglect any seemingly unimportant tool, because you are installing the window for many years and cold winters, and any little thing can result in an unwanted defect or, even worse, in the need to replace the window.

Window opening measurements

To measure window openings, they do not use any highly specialized tools, but the complexity of the measurement itself lies in the fact that measurements are taken both from the inside and from the outside, if you live on the second floor or higher, and the window being replaced is not on the balcony, this This is already a problem, here it is better to call a specialist with special equipment, unless, of course, you are a climber. In all other cases you will need:

• yardstick;
• plumb line;
• pencil;
• screwdriver.

Window openings need to be measured to the nearest millimeter, taking into account the skewness (if any), which may not be noticeable to the naked eye; these measurements will be used when making the window; they are individual for each window. When measuring the outer part of the opening for installing plastic windows, keep in mind that the size of the window from the outside should exceed the dimensions of the opening by 3-4 cm in width and 1.5-2 cm in height. This is necessary to ensure that the window does not fall out of the opening. Here we also measure the width of the window sill.

Ordering a window frame

If you decide to install a window yourself, pay special attention to the window manufacturer. As a rule, the manufacturer does not provide a guarantee for plastic windows if the installation is not carried out by its employee. Here you need to be very careful when measuring and installing, since no one will return the money you spent or replace the window if something went wrong. It is better to buy plastic windows from time-tested manufacturers.

Before ordering a product, think carefully about its configuration, from fittings to mosquito nets. If the window is large, it is better not to save on “blind” shutters - during the operation of the window you may encounter many inconveniences. In extreme cases, caring for “blind” shutters is much more difficult compared to opening ones.

Removing the old window

Before dismantling the old window, you need to free it from all objects that are on the windowsill and remove the curtains and tulle. If there is furniture in the room, cover it with plastic wrap; for these purposes, you can also use fabric, preferably thicker. Provide easy access to electrical outlets. After this, you can begin dismantling. Below are instructions for dismantling step by step.

1. First, remove the sashes from the old window.
2. Next, take out the glass.
3. When the window is completely free of glass, remove the window sill.
4. Then the window frame is dismantled.
5. The last to be removed are the slopes.

If you do not have a wooden or plastic window sill, but, for example, a marble one, then you may additionally need a hammer to dismantle it. Such a window sill needs to be broken starting from the center, but there are times when they can be removed entirely, although in order to lift such a weight, you will need 2-3 people, in this case, call someone you know. To dismantle the old window you will need the following tools:

• hacksaw for metal and plastic (you can use a jigsaw).
• chisel;
• hammer;
• putty knife;
• pliers;
• chisel;
• screwdrivers;
• multifunctional knife;

Preparation for installation

When ordering windows from the manufacturer and coordinating the delivery time, please take into account that delivery times may vary slightly; this may be influenced by the number of orders, upcoming weekends, traffic jams, etc. The whole question is to prepare the place where the windows will be placed before installing them, and all because plastic and glass products have quite a decent weight and can damage the flooring. It is best to select a corner for the frames in advance and cover it with thick cardboard. Once delivery has been completed and the windows have been dismantled, we will begin preparing the opening for installation.

Before installing plastic windows, you need to level out the potholes in the opening using a cement mixture; it is best to do this with a trowel, which will allow you to achieve a result that will be similar to a plastered surface.

Do not leave potholes and uneven areas without a backfill, this can lead to loose installation of the plastic window and the passage of air, noise and undesirable influence of atmospheric phenomena. Such gaps in preparation can lead to discomfort and reduced service life of the windows.

Window installation in stages

Before installing a plastic window, you need to remove the sashes from the frame, then remove the glazing bead and remove the glass unit from it. We immediately remove the protective film from the outside, since under the influence of temperature changes it can very quickly “solder” to the plastic and it will no longer be possible to remove it. We leave the inner side with the protective film pasted until the work is completed; this will protect the window from contamination during installation. Correct installation requires compliance with several rules and steps.

1. We make marks on the frame and drill holes for the dowels (necessarily from the outside, so they will not break), on which it will be attached in the opening, and mark the boundaries of the quarter from the outside.
2. We attach the connecting profile to the bottom of the frame and begin its installation in the window opening. The frame must stand strictly vertical; for this, technological wedges and a level are used.
3. Then we take out the frame and select linings of the appropriate thickness for the double-glazed windows.
4. If you use sealing tape instead of foaming, stick it along the marks on the street side and below on the profile.
5. We install the frame in the opening again and fix it with wedges.
6. After installation, we drill the walls through the holes on the frame and insert dowels into them, while making sure that the position of the frame is not bent.
7. As a result, a seam is formed between the frame and the wall; it needs to be foamed. This stage cannot be delayed, the foam expands, after 10, maximum 15 minutes after foaming, the sashes must be attached and closed, otherwise the foam may deform the frame structure.
8. The next step is to deepen the butt cord into the side and top seams between the frame and the wall by 50% of the opening width. The cord is treated with silicone.
9. Next, we install the window sill in the foam, for which we apply a strip of silicone at the point of contact of the window sill with the frame.
10. The window sill is placed under the frame using a level and secured from below with wedges.
11. The ebb should be attached to the stand profile using self-tapping screws, and do not forget to foam the lower part of the ebb, this will reduce noise during precipitation.

If you are planning to replace or install new windows, you will need to learn the installation process. It all depends on how you will install the windows: either with your own hands or by hiring a third-party company. It takes approximately 4 hours to dismantle and install the structure if you do not have experience in this matter. For a company employee who does this often, such work will take no more than an hour. But installing tilt-and-turn windows yourself requires some construction skills.

Window system components

Before you begin installation, you need to understand the nuances and details. First, you should find out all the names of parts and materials. The main load-bearing part is the frame. In the version of plastic windows, its production is carried out from a plastic profile, which can be single-chamber, double-chamber, etc. A special insert is placed in the center of the structure to ensure rigidity. In plastic systems, this insert is made of plastic; in metal-plastic systems, metal is used.

The profile system is assembled from 2 or more chambers

In addition, the profile is divided into classes: premium, standard and economy. All profiles manufactured at the plant are subject to certain standards. If you want to make a choice in favor of good tilt-and-turn windows, take the standard class. In terms of color, white windows are most often found, but other colors can be used: wood, brown. Products made from colored profiles will be more expensive than white ones.

Components of a plastic window

The main element of a window unit is the frame

The design of a plastic window includes the following parts:

• frame – the main structural part;
• if you have a large window, most often it is divided by a vertical partition, there may be several of them - it all depends on the choice of design;
• the part that is motionless is called blind, and the part that opens is called the sash;
• double-glazed windows can have different properties, for example, tinted, energy-saving, reinforced, using inert gas. In addition, they are single-layer, two-layer, three-layer or multi-layer - the choice is great;
• In order for the glass to hold securely, they are pressed with a bead, which is a thin plastic strip. For tightness, a rubber seal is used, most often black;
• fittings are always used - this is a special set of tilt-and-turn mechanisms that help open and close the doors and provide various functionality;
• in addition, seals are needed to ensure the tightness of the entire structure;
• Ventilated holes for drainage are made on the inside of the frame, which are covered with caps. Moisture formed when the temperature changes outside and inside the room passes through them to the outside;
• another part of the structure is the ebb - it is mounted outside, and the window sill is installed from the inside;
• parts located on the side of the frame are finished with slopes.

Is it possible to install the window yourself?

There is an opinion that installing windows in a house or apartment is a rather complicated procedure. It must be said that this is not so. What do you need to know during installation? To perform these works, you do not need special professional tools and equipment, or vast experience. The procedure includes two main points:

• dismantling the old window block;
• installation of a new window.

Removing an old window takes an average of 1.5 hours

If we talk about the time required to complete the work, the first stage will require approximately an hour and a half. Installing windows yourself will take less than three hours. It must be said that if you nevertheless decide to opt for the services of specialists, then you should demand certain guarantees from them.

If you installed the tilt and turn windows yourself, this will void your warranty. In this case, it is necessary to purchase structures directly from a manufacturer who has been working on the market for a long time and has good reviews from customers. If you decide to buy single-chamber or double-chamber windows in winter, you can always count on a significant discount.

When a window is purchased from a company that also carries out installation work, the customer has a warranty on the fittings for about 5 years. If you install it yourself, you can get a warranty directly from the manufacturer, that is, at the place of purchase.

In order to install windows in a brick house, cinder block house, gas block house or apartment, you must first order a tilt-and-turn or blind structure from the manufacturer, and this requires accurate measurements.

Step-by-step instructions for correct measurements

When you place an order, you will be asked to indicate the following dimensions: the width and height of the structure, the width and length of the slope and window sill.

Before ordering a window, you must take correct measurements of the structure.

Before you start measuring, do not miss an important point - what type of opening you have: with or without a quarter. Look carefully at the window opening: if the outer part is narrower, it means there is a quarter-sized opening in front of you. The measurement is carried out as follows: you need to measure the narrowest part, you will need to measure in several places, find the smallest value, add 3 cm to it. The height is indicated as it is. If your opening is even, then the measurements are done as follows: after measuring the width, subtract 3 cm; measuring the height, minus 5 cm. Read a detailed article about.

Before taking measurements, you need to determine the type of window: with or without a quarter

To determine the size of the window sill, you need to add about 10 cm to the width of the opening inside the window. For low tide, the same is done, only along the outer part of the window. Everyone chooses the width for the window sill for themselves: it is better if it protrudes slightly beyond the radiator.

In addition, when placing an order, you need to decide what components your design will be made of: what options for two-, three- or single-leaf windows you need, how they will open, on which side the capercaillie is located. Don’t forget to decide on the type of fittings (handles, locks, ventilation mechanisms).

If you order several designs at the same time, the width of all openings may be different, but the height should be the same; you must choose the smallest size. Please note that window openings can be located at different distances from the floor. In apartments, the distance from the floor to the window is approximately 80 cm, while on the balcony the windows can be from the floor. Accommodation in a private house can generally be anything at the discretion of the owners.

Features of measurements for glazing balconies

To determine the width of the glass structure, it is necessary to measure the length of the part of the balcony on which the balcony window will be installed, minus 7 cm on each side. This distance will be required for the installation of the corner profile to which the structures of the side elements of the balcony are attached. The height is calculated as the distance from the support to the roof on the balcony or loggia, and a tolerance of 3 cm must be subtracted for the gap.

How to correctly measure windows in a country house

To correctly measure the dimensions of a structure in a private house, knock out part of the slopes on both sides. Very often it turns out that the window opening is much larger than the window that is installed in it. This means that when the structure is dismantled, some of the materials with which the space was filled will also be removed.

Preparing to install a window structure

After you remove the old window, you will need to inspect the resulting opening, remove all parts that may fall off or collapse; if there are protruding elements, they should be knocked down. Then clean the opening from construction debris and dust. If there are large depressions, it is better to cover them with cement. You can also treat everything with primer.

The base will need to be cleaned before installation.

Having finished working with the opening, you need to prepare the PVC window, which is to be installed. To do this, you need to remove the window sashes; if it is solid, double-glazed windows. If your frame has small dimensions, then you can install it without removing the double-glazed windows and sashes. The outer part of the frame should be freed from the film that protects it.

Installation Technology Guide

The finished plastic window is brought into the opening, placed on support blocks and aligned horizontally. After this, using a level, the window is aligned vertically and secured in this position with spacer blocks.

Installation of both fixed windows and opening sashes is the same. There are two options for installing windows: with and without expansion of the structure. When using the first option, holes are drilled through the frame through which anchor bolts are driven into the wall. This method is more complex and more reliable.

When installing a window using the unpacking method, holes are drilled in the frame and wall, into which anchors are then driven in.
Places for attaching anchors and support blocks

If the installation is carried out without unpacking the frame, the window is fastened using special ones, which are attached to the profile and then to the wall. This option is faster. However, it must be taken into account that under significant wind loads, the frame structure may warp or it may sag. If you decide to mount it on a plate, you should choose thick, wide options. Please note that if the region in which you live has a strong wind load or windows will be installed at a height, then you should use the option of unsealing the frame.

Mounting on anchor plates

There are nuances to placing a window in the opening. If the walls are made of foam blocks, brick, cinder block, gas silicate or concrete, then the frame is placed 2/3 deep from the internal thickness of the opening. If the walls are insulated with foam plastic, then the fastening must be done before the insulating layer. When insulating and facing with bricks, the window is installed in the insulation zone.

It is very important to choose the correct installation depth

The installation sequence must be followed:

• Having inserted the frame, level it using support and spacer blocks;
• then attach it to the wall;
• after installing the structure, it is necessary to assemble the window;
• then you need to check the normal operation of the shutters and all mechanisms; to do this, open and close the window;
• after everything has been checked, the doors must be tightly closed and the gap around the structure must be sealed. For this purpose they use .

However, it must be remembered that in direct contact with sunlight and the external environment, the material loses its properties and is destroyed. To protect it, you need to create, this can be a special film that needs to be glued to the outside and inside of the window. After the foam has dried, it is necessary to finish the slopes on both sides (external, internal) of the structure. You can open the window a day after blowing the gap with foam.

To ensure proper installation on both windows and windows, follow these simple rules:

• we install the ebb from the outside in a special slot in the frame or attach it to it with self-tapping screws;
• the window sill is installed as follows: it is necessary to trim it from the edges so that it fits the width of the window opening and rests against the end of the stand profile;
• the level is leveled using special pads, after which the space under the window sill is blown with foam or filled with mortar.

According to the principle described above, windows are installed on a balcony or loggia, in brick or concrete walls. However, keep in mind that the entire weight of the window structure will be carried by the parapet, so you need to strengthen it.

Mistakes you can make when installing windows

There are a number of points that you should pay attention to when installing the structure so that it has a long service life:

• you cannot install the window with the glazing beads facing outward, as this reduces the structure’s burglary resistance, since the glazing bead can easily be pulled out and the glass unit removed;
• you need to be careful about leveling the structures when installing the window, otherwise opening and closing the sashes will be difficult;
• It is imperative to protect the mounting foam from direct sunlight to avoid its destruction;
• It would be wrong to choose to fix the frame structure only with mounting foam: it is absolutely necessary to attach it to the wall, otherwise it may simply fall out.

By following all the installation rules, you can successfully install the window structure yourself, and if you seek the services of professionals, you will be able to monitor their work at any stage.

Most homeowners choose to install plastic windows not only because of their excellent performance, but also because of the ease of installation. This process is simple due to the fact that the design provides very easy-to-install fasteners and additional parts that are included in the package of the window. Many people are interested in how exactly professional installers install windows. With the most minimal skills in using tools, any homeowner can install such windows.

Of course, as with the installation of any structural element, when installing PVC windows you will need to observe a number of features and certain actions. It is advisable to carry out this kind of work with an assistant, even one who does not have any construction skills; when leveling the window, some difficulties may arise if you do this work alone. Proper execution of all installation nuances will help you complete the job accurately and save on the labor of hired workers.

Carrying out measurements and calculations

Before purchasing windows, you should take measurements of the openings - based on this data, you will place an order to the workshop. When taking measurements, you need to take into account whether they are a quarter or not. Foam concrete buildings are characterized by quarter openings, which greatly reduces heat loss. For an opening without a quarter, when ordering fiberglass windows, the length will be 5 cm less than the same parameter for the opening. 3 cm is subtracted from the value defined as the width of the opening. Gaps of 1.5 cm should be provided along the contour - they are necessary in order to carry out foaming. An additional 3.5 cm should be left at the bottom for installing the window sill. According to GOST, 2 cm should be left around the perimeter.

To take correct measurements for a quarter opening, measurements must be taken at the narrowest point. When ordering windows, add 3 cm to the measured width; the length does not change the value.

More often, PVC window structures are not installed in the middle of the opening, but at a depth of approximately 1/3 from the outer plane. But if you are going to install the structure yourself, you can move the window a little at your discretion. To order sills and window sills, you should definitely take these parameters into account. Add 5 cm to the widths calculated for the intended location of the windows.

When determining the width of the future window sill, it is necessary to take into account the battery - it should be covered by the window sill by about half. Add another 2 cm - the window sill will need to be placed under the base of the window frame. You need to leave a margin in length - at least 8 cm. But it will be much better if you add 15 cm - this allows you to cut the window sill more beautifully.

Plastic side plugs are usually included with ebb and window sills. You shouldn’t refuse them, although some masters do just that.

Window frame installation methods

The technology for installing polyvinyl chloride windows does not depend on how many internal chambers are in the metal-plastic profile, nor on the number of chambers in double-glazed windows. When developing an installation plan, you will need to take into account the following points: the material from which the walls of the home are made, and the dimensions of the plastic window structure. Depending on this, the method of fastening and the devices that will be used are determined.

Plastic window frames can be fixed in the opening using the following elements:

• using dowels, mounting anchors, which must be inserted into the walls through special through holes, which are made in the profile in advance;
• Another option is special toothed plates pressed into the profile, which are not embedded in the wall, but are placed “off-the-cuff” and fixed with screws.

Option 1 is considered the more reliable of them. It is more often used in cases where it is necessary to install window systems of considerable size and weight. Window frames with through fastening quite well resist various shock loads that can arise, for example, when using PVC systems with sashes that open in different positions. Anchors passing through the plastic frames allow more precise adjustment of the structure during installation both vertically and horizontally.

Those who want to find out the method of correct installation of PVC windows that are small in size with fixed double-glazed windows may be interested in fixing the structure using anchor plates. Fastening elements will not spoil the appearance of the window - they are covered by slopes.

To install anchor plates in wall openings made of brick or concrete, you will need to make recesses. If you do not do them, you will need to apply an extra leveling layer before installing the internal slopes.

Sometimes installers try to combine these 2 methods. The anchors are inserted into the walls through the bottom profile, that is, the base of the window structure and the sides of the frame, and the upper part is fixed using plates. If PVC windows are installed in a bathhouse built of wood, anchor plates should not be installed - they become loose during operation. In some cases, galvanized screws are used instead of anchors.

The nuances of installing plastic windows in wooden buildings

The installation process will be significantly influenced by the type of material from which the housing is built. For example, for walls made of hollow or solid bricks or foam concrete, the differences will only be in the depth to which the anchors are installed. But openings in walls made of logs or beams will require a special approach. Here you will need to take into account the installation method and choose the right time for this.

Plastic windows can be installed in walls made of wooden building materials only a year after the construction of the house. It’s even better to wait 2 years - during this time the shrinkage process will enter the stage in which subsequent operation will be longer and more reliable. For buildings made of laminated veneer lumber, the shrinkage period lasts the fastest.

Window installation should not be carried out immediately in the opening, as is sometimes done in villages.

A plastic window should be inserted exclusively into a wooden frame, which will protect the window structure from distortion. The window unit itself must be free of any damage; the presence of defects and rot is unacceptable. Before starting work, it should be treated with an antiseptic composition.

After the PVC windows are installed in place, the shrinkage of the log house does not end. True, it will not continue as intensely. To prevent it from causing crushing damage to plastic structures, it is recommended to leave a gap of 3-7 cm between the top edge of the frame and the window frame. After the window is put in place, the gap is filled with jute insulation and closed on both sides with platbands.

The building codes do not contain precise recommendations on what materials should be used to install ebbs and window sills in wooden houses. As a rule, standard sills are installed, which are ordered in one set with the window design. Window sills can be made of wood or polymers. The bottom profile can be supported on a wooden window sill, that is, it can be installed before installing the window.

For those who are planning to install windows themselves, but do not have much experience in this matter, the following information may be useful. Since wood allows moisture vapor to pass through well, the technical qualities of the polyurethane foam used to install the window are seriously reduced. To ensure that the foam blown around the perimeter of the structure is not exposed to moisture and does not get wet, a foil polyethylene tape should be applied to the window block along the line on which it is applied. This nuance is not specified in the regulations, but experienced installers highly recommend not neglecting such equipment when installing a window.

Standard methods for installing plastic windows

The technology for installing plastic window structures includes the use of polyurethane foam. In addition to providing insulation, it will add additional rigidity to the connection between the opening and the frame. Thus, a layer of polyurethane foam, obtained as a result of its polymerization, simultaneously protects the opening and fixes the structure. To ensure that the foam layer does not lose its technical properties under the influence of adverse external influences, it is better to surround it with additional insulation.

As to when exactly to install PVC windows, the decision is made by the homeowners. You can also come across the opinion that it is better to do the installation not in summer, but in winter - in this case, all installation flaws will appear immediately and can be corrected very quickly. When choosing polyurethane foam for work, pay attention to the information on the composition - it should indicate at what temperature this product can be used. The foam will only cure at the temperature specified in its performance characteristics, so you should not use foam intended for use in extreme cold conditions for summer work, and vice versa.

You can read about how to carry out foaming in the instructions that the manufacturer attaches to a specific product. Usually foam starts from the bottom, gradually moving upward. Movements should be rotary and circular. To reduce the consumption of expensive material, it is better to blow out the foam in several stages, calculating segments of approximately 25-30 cm.

To shift the dew point, it is better to perform foaming with different densities. In practice, it looks like this: they try to compact the outer layer of foam less than the layer facing inward. The foam must be poured around the perimeter of the window frame as evenly as possible, without gaps or voids.

How to prepare a window opening for work?

To install PVC windows, you will need to carry out preparatory work before work. Before installation, any contamination should be completely removed from the window opening: dust, construction debris, particles of old paint. When carrying out work independently, craftsmen should know that when installing a new plastic structure in a used wooden window frame, it is better to completely plan off the top layer. It is not reliable enough; it is better to remove it completely so as not to disturb the adhesion of the foam to the surface.

If the gap between the opening and the window frame does not exceed 4 cm, they are filled only with foam. If the gaps are wider, it is better to partially fill them with other, cheaper materials. These can be pieces of timber, drywall, polystyrene foam, brick fragments and other construction waste.

If you or someone you know has previously used the services of companies installing double-glazed windows, then you know that installation can be normal and in accordance with GOST. The second option is more expensive, but if all the requirements are met, the quality will be much higher than in the first (you can read more about the standards in GOST 30971-02).

Consists of several stages.

Note! Manufacturers do not provide a guarantee if the measurements were not carried out by their employees. If installed incorrectly, the windows will soon begin to freeze, and if even the slightest mistake was made in the calculations, the structure simply will not fit into the opening.

However, if you study all the intricacies of the process, then no difficulties will arise during installation. Moreover, this way you can save a decent amount of money.

Stage 1. Measurements

In most apartments there are openings without a quarter.

Note! A quarter is an internal frame 6 cm wide (or ¼ brick, hence the name) that prevents the window from falling out and strengthens the structure as a whole.

If there is no quarter, then the frame will be installed on anchors, and the foam will be covered with special covers. Determining the presence of a quarter is quite simple: if the internal and external widths of the frame are different, then there is still a quarter.

1. First, the width of the opening is determined (the distance between the slopes). It is recommended to remove the plaster for a more accurate result.
2. Next, the height is measured (the distance between the slope above and the window sill).

Note! The measurements must be repeated several times and the lowest result taken.

To determine the width of the window, two installation gaps are subtracted from the width of the opening. To determine the height, the same two gaps plus the height of the profile for the stand are subtracted from the height of the opening.

The symmetry and straightness of the opening are checked, for which a mounting level and plumb line are used. All defects and irregularities must be indicated in the drawing.

To determine the width of the drainage, add 5 cm to the existing drainage for bending. Also, the width of the insulation and cladding is taken into account (subject to subsequent finishing of the facade).

The dimensions of the window sill are determined as follows: the width of the opening is added to the size of the overhang, and the width of the frame is subtracted from the resulting figure. Regarding the offset, it should cover the heating radiator by a third.

Note! measured after installation is complete.

Stage 2. Order

After measurements, the finished drawing should be taken to the window manufacturer, where all the necessary fittings will be selected. It is worth remembering that installation can be performed in one of two existing ways:

In the first option, you will have to pull the package out of the frame, insert it into the opening and install the glass back. In the second case, the entire structure is attached as a whole. Each option has disadvantages - if you pull out the package, it can; and vice versa, if the window is installed assembled, it can be damaged due to its heavy weight.

Stage 3. Preparation

This stage of installation begins only after delivery of the ordered windows. First, the workplace is cleared, all furniture is covered with plastic wrap (there will be a lot of dust).

Step 1. If required, the glass unit is removed from the window. To do this, the glazing bead is slightly pryed with a staple and pulled out. First of all, the vertical beads are removed, then the horizontal ones. They must be numbered, otherwise gaps will form after installation.

Step 3. The bolts are unscrewed after the plugs are removed from the canopies. The handle is turned to the “ventilation mode” (in the center), the window is opened slightly and removed. All that remains is the frame with imposts.

Note! Imposts are special jumpers designed to separate the sashes.

Then you need to make a marking for the anchors and make holes along it - two on the bottom/top and three on each side. To do this, you will need ø1 cm anchors and a drill of the required diameter.

If the material from which the walls are made is not dense (for example, cellular concrete), then fastening is carried out using anchor suspensions. The latter should be fixed to the wall and frame with hardened self-tapping screws (eight pieces for each).

Note! To avoid the formation of a thermal bridge in the window sill profile, it should be filled the day before installation. This way the element will not freeze.

Stage 4. Dismantling work

This procedure is recommended to be carried out immediately before installing a new window. In most cases, the old ones are thrown away, so the structure can be torn out along with the fastening, and if necessary, the frame can be sawed.

Step 1. First, the seal and thermal insulation are removed.

Step 3. The window sill is removed and the cement layer underneath is cleaned off.

Step 4. Adjacent surfaces are treated with a primer material (by the way, many installers forget about this). In the case of a wooden opening, a layer of waterproofing material is laid around the perimeter.

Note! Installation can be carried out at a temperature not lower than -15ᵒC. Polyurethane foam must be frost-resistant.

Stage 5. Installation of a plastic window

Step 1. First, wooden wedges are placed around the entire perimeter, a window is installed on them (this will make it easier to level the structure), only after this is it fastened to the wall. You can leave the backings - they will serve as additional fasteners.

Step 2. The absence of a support profile can be considered a gross violation of GOST standards, since it is not only needed for stability, but also makes it possible to install a low sill with a window sill. In the absence of a profile, they are attached directly to the frame, which violates its tightness.

The correct location of the stand profile is shown in the diagram.

Step 3. Next, the evenness of the window is checked in three planes, for which a mounting level and plumb line are used. It is typical that traditional bubble levels are not suitable for this due to insufficient measurement accuracy, so it is better to use.

Step 4. If the window is level, then it is secured with anchors. To do this, a wall is drilled using a hammer drill through pre-prepared holes in the structure (approximately 6-10 cm). The lower anchors are fixed (not completely), the evenness of the package is checked again, after which the remaining points are attached.

Note! The final screed is made only after the final inspection. Do not tighten too much, otherwise the structure will “skew”.

Stage 6. Drainage

From the outside, the ebb is attached to the stand profile with self-tapping screws. The joints are carefully sealed with sealant to prevent moisture from penetrating into the structure.

The edges of the ebb are recessed several centimeters into the walls, having previously made indentations using a hammer drill.

Note! Before installation, the bottom gap is also sealed.

Stage 7. Window assembly

After attaching the anchors, the glass unit is inserted back.

Step 1. The glass is inserted and fixed with glazing beads (the latter should snap into place, for which you can lightly tap them with a rubber hammer).

Step 2. The doors are opened and their tightness is checked. In the open position, arbitrary opening/closing of the sash cannot happen if the window is installed level.

Step 3. The assembly seam is sealed on the sides. Polyurethane foam will provide high-quality waterproofing and prevent glass fogging. Before and after sealing, the seams are sprayed with water to improve polymerization.

Note! The seams are filled to no more than 90%, otherwise the structure will “lead.” If everything is done correctly, after drying the foam will protrude out a few centimeters.

Step 4. The perimeter of the window is glued with a special vapor barrier tape, and material with a foil surface is used underneath.

Stage 8. Installation of the window sill

Step 1. The window sill is cut so that it fits into the opening and at the same time rests against the lining profile. There remains a small gap (about 1 cm) for thermal expansion. Subsequently, the gap is hidden by plastic

Step 2. Wooden wedges are placed under the window sill. It needs to be laid with a slight slope towards the room, and then applied with something heavy until the foam dries. Additionally, the window sill can be fixed with anchor plates.

conclusions

Now you know how plastic windows are installed, so you can safely get to work. The final check of all elements can be carried out only 24 hours after completion of installation (then the foam will have already “set”).

The described technology is also quite applicable to, although it also has its own nuances - such as, for example, installing a parapet to create a partition.
