Panel houses are familiar to every Russian from the numerous high-rise buildings in residential areas of the city. Because of not High Quality construction, there is a rather skeptical attitude among consumers towards this technology. According to the established opinion, panel technology only applicable in multi-storey construction budget housing and does not provide the opportunity to build warm and beautiful house. We hasten to dissuade you. A panel house is a modern, warm and, in many cases, pre-fabricated structure with your own hands.
Competitive technologies for rapid construction of buildings
It's about three technologies: “sip panels”, three-layer concrete panels, KA-panels. Cost of building a box one-story house for 150 sq. meters with the choice of project will cost:
- from vulture panels - $8.5 thousand, frame construction time - 1-3 weeks;
- made of three-layer concrete panels - $6 thousand, construction period of the box - 10 days;
- from KA panels (calar load-bearing panels) – $7.5 thousand, 120-year guarantee, construction period – 10-15 days.
The listed construction technologies are offered at comparable prices for building a box house. Each has its own characteristics, advantages and disadvantages that are worth special attention.
Three-layer concrete panels for house construction
Concrete three-layer panels are considered by many to be more reliable design compared to other prefabricated technologies. Thanks to the insulation, the house also becomes very warm. Due to the hollow core filled with mineral filler, the design of the box does not create an increased load on the foundation, while a building made of concrete structures is definitely stronger and more stable than a house made of vulture panels.
House kits based on standard designs and with a tiled facade are offered for sale. Purchasing a ready-made kit allows you to assemble a box in 10 days, which from the inside only requires inexpensive repairs thanks to the perfect smooth walls. Reinforced concrete structure has high strength. With its help you can build tall houses.
The disadvantages of this technology include the need for installation using heavy construction equipment. Wherein panel houses You can build from three-layer concrete with your own hands (photo) 20-30% cheaper than a similar structure made from vulture materials. This is a very significant plus and a factor contributing to the choice of this particular construction method.

Another option for constructing a panel house involves the use of sip panels. We are talking about well-known special building panels made of polystyrene foam and OSB boards. There are both standard structural elements on sale that can be used to build your home, as well as ready-made house kits.
The Canadian sip panel is technologically related to multilayer sandwich panels; it was developed in Canada, so in advertising you often hear about Canadian houses. This material, despite its lightness and apparent fragility, it is able to easily withstand temperatures in the range from -50C to +50C, earthquakes up to 7.5 points. In terms of its heat capacity, a plate based on polystyrene foam retains heat 6 times better than brickwork. Despite the porous structure, the insulation of the sip panel does not burn.
You can freely build a house using sip panels according to any chosen project with your own hands; for this you will need 1-2 assistants. Construction can take from 3 weeks to build a box up to 3 months on a turnkey basis; installation can be carried out both in winter and summer time. The advantage of this type building material is the ease of construction, ease of installation and a wide variety of standard projects that can be chosen for the construction of a cottage.
There are many opinions regarding the environmental friendliness of sip technology. Buyers need to independently assess the risks and read the materials about the two components of the sip board: expanded polystyrene and OSB. Both materials are time-tested and environmentally friendly.
Buying a ready-made house kit will help you avoid mistakes in design calculations. Assembling a house according to your own sketch from standard elements will cost less. If there is a need to further reduce the cost, you can make a sip panel yourself. The panel house shown in the video instructions can be assembled with your own hands in a video within a few weeks or less. How to design a house, draw up a drawing and do the installation is told by an experienced architect in a video.

Based on the list of works for installing KA panels, this option panel construction more suitable for self-installation. Simple and quick assembly is undoubtedly key feature this construction technology. This is a promising building material.
Conclusion
Buyers today have a choice of how to build a house, cottage, or outbuildings from sip panels, KA panels or reinforced concrete sandwich panels with their own hands. Each of the described technologies is available for self-construction. The panels allow you to build a house similar to a house made of profiled timber, but the structure will cost much less.
The construction market offers modern, more convenient to use, cost-effective, environmentally friendly clean materials. Thanks to technological progress and high competition, they have affordable prices and good quality. Such modern building materials are sip panels.
Gaining popularity, this is an excellent type of construction country house.
What are sip panels?
The sip panel consists of two OSB boards (oriented strand board, similar to chipboard, but more durable and elastic) and polystyrene foam between them. They are glued with polyurethane glue under high pressure. Expanded polystyrene is an excellent insulation material, does not support combustion and is not affected by moisture.
The slabs vary from 9 to 12 cm, polystyrene foam from 10 to 20 cm. Depending on the thickness of the panel, the material is selected for the floor, for the walls or for the ceiling.
Advantage of SIP material
The advantage of sip panels is:
- ease of installation (no need to insulate walls or sheathe insulation);
- in ease;
- at an affordable price;
- the ability to order the desired size and desired shape;
- naturalness and harmlessness, thanks to the wooden surface;
- high noise and heat insulation;
- ease of installation with your own hands;
- fire resistance, thanks to special impregnation.
What are the advantages of structures made from sip panels?
For construction country house, it is advisable to use sip panels. Their main advantage is their compactness: with a small thickness they have high thermal insulation, comparable to the thickness of an insulated concrete or brick wall. 
The lightness of this design does not require a reinforced deep foundation, which greatly simplifies the work.
Ease of installation helps rapid construction country house and the absence of errors in the design. The presence of individual panels in size and shape speeds up and simplifies the process as much as possible.
Technology for constructing a country house from sip panels
Construction of a country house with your own hands is possible for anyone. First you need to study the construction technology.
Preparatory stage
Having decided to build a country house from vulture panels, you need to contact the organization that produces them. They will provide many projects, one of which can be selected and edited to suit individual wishes. 
According to the approved project, the manufacturer creates a set of materials of the required sizes and shapes, with each panel marked. Such parts do not require additional processing, trimmings, they are simply mounted in place.
For installation it is necessary to prepare well-dried wooden boards the size of the grooves of sip panels.
Foundation structure
For a light frame country house, a shallow strip foundation made of monolithic reinforced concrete. To reduce its buoyancy, the base is covered with sand.
A concrete foundation involves laying pipes for communications before pouring concrete. So strong stable base has a labor-intensive process. 
An even more labor-intensive type of foundation - on screw piles. Requires a special drilling machine. Its advantage is the creation of a ventilated cellar, which is important in humid conditions of the dacha.
The foundation is coated with mastic, and a strapping beam is laid on it - the basis for fastening the sip panels. At the corners, the structure is fastened with locks made of grooves and tenons, screwed to the foundation using anchors, and is also treated with waterproofing.
Walling
The construction of the walls of the house occurs in the following sequence:
- A board of width and thickness corresponding to the groove of the selected panel is laid on the strapping beam along the entire perimeter. It is attached using self-tapping screws, every 15-20 cm. Foamed grooves of the panels will be inserted into it.
- Connecting bars are installed in the corners to join the two panels. The grooves are also treated with a small volume of polyurethane foam; it should be taken into account that it expands. After docking.
- Then the remaining panels are joined to the corner elements, the grooves are foamed, and the connection is fixed with self-tapping screws.
- After installing all the walls, the upper grooves are foamed, and the upper trim beam is placed in them.
Roof installation
The roof of a garden building should protect from bad weather and noise, and retain heat. These functions are perfectly performed by sip panels.
For fastening, a roof frame is created with spikes corresponding to the grooves. Thus, the structure is assembled very quickly. If garden house large, construction will require additional crossbars to hold the panels.
Installation of windows and doors
A garden house built in this quick way is not subject to shrinkage, and windows and doors can be installed immediately. Installation is possible with your own hands.
To do this you will need: support wedges for leveling, a level, fasteners, polyurethane foam, and tape.
Installation procedure:
- Windows (doors) are inserted into the finished holes and secured on the sides with wedges.
- Then the level is checked and adjusted.
- After alignment, you can fix the fasteners to the opening, the free space is foamed.
- The waterproofing film of the window and walls is connected using tape.
External and internal finishing
Finishing of the structure can begin immediately after completion of construction. This is important to maintain a presentable appearance. 
The surface of the sip panels is flat and smooth – it does not require careful leveling, which will speed up the finishing process. There are even options for varnishing sip panels, which emphasizes the closeness to nature and naturalness.
This building material is suitable for any type of external and internal decoration.
Building a country house with your own hands is much faster and easier if you use modern material. Its cost is paid off not only by ease of installation - time savings, but also by subsequent savings on heating costs.
Technology frame construction is strongly associated with the high speed of construction of houses, their efficiency, and variability in the selection of materials. One of the most practical options are SIP panels (SIP panels). Based on translation from in English, they are often called thermally insulated, structural. What distinguishes them from sandwich panels and how to properly build frame houses from SIP panels?
SIP panels - what is it?
SIP panels are one of the modern multilayer materials that are used in construction residential buildings. Their performance properties are determined by their special structure and manufacturing method.
Three-layer SIP structure
SIP are three-layer construction panels that are made by pressing. As a result, the material is almost seamless. The first layer is oriented strand board (OSB), the second is polystyrene foam, the third is another OSB.
Oriented strand boards are made from several layers wood shavings, which are interconnected by synthetic resins. They are pressed at high temperature and pressure. In each layer, the chip direction is different, which gives the finished sheet high strength.
Please note: the greater the number of chip layers, the better adhesive composition, the higher the moisture resistance and strength of OSB.
Oriented strand boards have stable dimensions, provide excellent noise and heat insulation, are resistant to temperature changes, and are easy to install.
Expanded polystyrene consists of individual microporous granules, inside of which there are voids. They determine the lightness of this insulation, its good soundproofing properties. Expanded polystyrene does not release toxic substances into the air, is frost-resistant, and resistant to mold.
The advantages of these two materials largely determine the advantages of construction from SIP panels.
Sandwich panels and SIP panels - what are the differences?
It’s worth mentioning right away that at its core, SIP is a type of sandwich panels. It is characterized by: a combination of OSB and expanded polystyrene, a certain set of performance qualities.
There are other sandwich panels:
- casing: galvanized steel with polymer coating, rigid PVC sheets, plasterboard, chipboard, ;
- thermal insulation: mineral wool, .
The general prefix “sandwich” only means multi-layered material.
The manufacturing technology also distinguishes SIP from other sandwich panels. Densely compressed into monolithic sheets, they are superior to analogues made from other materials. But most sandwich panels can be easily disassembled into layers.
Concerning bearing capacity, then SIP can be structural elements houses, to bear the vertical load from floors, roofs, etc. Sandwich panels are more suitable for internal partitions, additional insulation external walls.
Advantages and disadvantages of the material
Equipped houses made from SIP panels are different high level heat saving. They can be almost 1.5 times warmer than similar buildings made using standard frame technology. This allows you to reduce energy and heating costs.
A favorable microclimate is formed inside the building. During cold weather, the air in the rooms quickly heats up, but takes a long time to cool down.
To build a warm “box” at home it will take literally 10-14 days, regardless of the time of year. And upon completion of the work, you can immediately begin finishing, since the walls practically do not shrink.
Also, thermally insulated panels in most cases do not need additional steam and wind protection.
Their disadvantages include: high cost when using high-quality OSB, the flammability of wood and the “thermos” effect. The latter implies the need to install forced ventilation under conditions of an almost closed thermal circuit.
How to build a house from “warm” panels
Building a frame house from SIP panels with your own hands is not difficult. Not the least role in this is played by the relative lightness of the material and its strength.
The sequence of work will be as follows:
- Carrying out earthworks to determine soil quality.
- Marking the foundation and laying it. Due to the lightness of SIP, it can be a budget tape, pile or screw option.
- Construction of the lower tier of the building (subfloor). The slabs are laid from the corner, not forgetting to do technological holes for communications.
- Construction of external walls and partitions inside the house. The connection of the panels should be as tight as possible, without voids.
- Laying of floor panels from SIP panels, construction of the second floor using already proven technology.
- Installation rafter system and its SIP sheathing.
Construction of a residential building from SIP panels saves time and labor. Instead of covering the external walls and insulating them (with the installation of sheathing), you should only install a ready-made three-layer material With the right set properties.
Connecting panels to each other and to other structural elements
High-quality SIP fastening means the absence of cold bridges, ease of assembly of individual parts, and the strength of their connection. Each of the main structural units has its own characteristics.
Fastening panels to the foundation
To install wall SIPs to the foundation, waterproofing (roofing felt) is first laid on it, and trim boards are secured.
After this, the floor panels are laid. They are fixed to the base using anchors. The distance between fasteners should not exceed 2 m.
Installation of this type of SIP panels occurs as follows:
- Self-tapping screws with a diameter of 4.8 mm and a length of 95 mm connect the ceiling to the trim boards.
- Using 3.1x50 mm self-tapping screws, fix the wall panel to the DO. The distance between fasteners should not exceed 150 mm.
During the installation process, check the evenness of the SIP fastening using a building level.
Corner connection of wall elements
In outdoor and internal corners(90°) panels are joined together using wooden dowels. Typically these are boards 50 mm thick and 150 mm wide. An alternative for building a house is I-beams.
Please note: joints individual elements foam first polyurethane foam.
The dowel is attached to one of the walls using self-tapping screws 4.8 mm in diameter. The distance between them should not exceed 200 mm.
The panel of the other wall is fixed to the dowel with 3.5 mm screws, maintaining a pitch of no more than 150 mm. Projecting part OSB boards fixed to the end of the wall panel in the same way.
Joining wall and floor panels
This is a complex SIP connection unit at home, which involves the use large quantity fasteners.
- The floor slab is fixed to the lower wall using self-tapping screws, the diameter and length of which are 6.3 and 240 mm, respectively. The distance between them should not exceed 300 mm.
- A trim board is mounted on top of the ceiling. To do this, use 4.8x95 mm self-tapping screws, screwing them in increments of 100-200 mm.
- Using 3.5x51 mm self-tapping screws, fix the panels of the upper wall to the trim board. The distance between them should not exceed 150 mm.
- OSB on the floor trim board is also secured with 3.5 mm self-tapping screws. However, a step of 300 mm is acceptable.
All installation joints when assembling a house pre-foamed appropriate composition.
Angle of connection between roof and wall
To connect the roof and wall, perform the following steps:
- A mauerlat is fixed to the wall panel - a support for the lower level of the rafter system. To do this, use 4.8x95 mm self-tapping screws in increments of up to 200 mm.
- WITH end side The roofing SIP is attached to the strapping board. Self-tapping screws with a diameter of 3.5 mm are installed at least 150 mm apart from each other.
- The roofing elements are connected to the Mauerlat with 6.3x240 mm self-tapping screws. The distance between them should not exceed 300 mm.
note: fasteners with a diameter of 6.3 mm are also used to secure roofing panels to a ridge beam.
Construction from SIP: conclusion
If you are still not sure whether to build a house from SIP panels, pay attention to more than 20 years of experience in Canada and Finland in this area. For countries where there are strong hurricanes and no less very coldy, he is more than successful.
The secret lies in the unsightly wooden dowels used for joining panels. They are bonded into a rigid, frame that, when paired with durable SIPs, is able to withstand the elements.
However, to obtain such a safety margin, it is important to follow the house construction technology down to the smallest detail. One mistake can jeopardize the work of many people and the lives of future residents. That's why part construction work It is recommended to entrust this to experienced specialists.

SIP panels are a type of so-called sandwich panels. Their function is bearing support, for this reason they are used for the construction of frame-panel structures.
Canadian technologies have made it possible to connect panels using a tongue-and-groove method. The panels include three layers: insulation and two rigid sheets. The wooden frame performs a load-bearing function and can withstand heavy loads. 
Types of sip panels:
- Roofing;
- Wall;
- For floors.
The composition of such panels includes OSB and foam boards; their combination gives high strength and thermal insulation. The materials are joined with a special polymer glue. Polyurethane foam, fiberglass, mineral wool, and polyisocyanurate foam can also be used as insulation.
How are houses built from this type of panels?
Frame, floor, roof frame, interfloor ceilings built from beams different sections. Thanks to insulation, you can build attics with less money.
OSB boards are made from shavings, the fibers of which are laid in different directions, and are impregnated with a special moisture-resistant composition. External finishing can be done with siding, brick or ceramic panels.
Walls can be insulated waterproofing film and drywall.
Pros and cons of building houses from sip panels
A house made of sip panels is hygienic, environmentally friendly and fire resistant, without posing a danger to people or animals. 
A thick layer of polystyrene foam will keep the house warm even at high temperatures sub-zero temperature outside and will save the family budget on heating. Even panel and brick houses. For comparison, for a brick house to have the same thermal conductivity, the walls must be 1.5 meters wide.
Along with this, the panels have high sound insulation.
The use of sip panels allows increase the speed of building construction several times (1-2 months), and you can work with them at any time of the year. They are easy and convenient to transport.
Price issue
Let’s find out how much it costs to build such a house. To date construction from sip panels is the cheapest option. Price per square meter“turnkey”, including foundation, finishing, roof, electricity, heating is 300-450 USD. For example, for this price you can build a brick house box.
Due to its lightness, the impact on the foundation is minimized.
The main disadvantage of “Canadian houses” is the conservatism of the population. Many are afraid to use new technologies to build a house as a reproach to the usual ones (brick, panel houses). Of course, all building materials have their disadvantages and advantages, but in the case of sip panels there are no serious disadvantages.
Often, competitors create a negative opinion about these buildings. This applies to both sellers of building materials and builders who adhere to traditional construction methods.
Myths about sip panels
Ventilation must be carefully considered
This is not necessary, the ventilation just needs to be better than in traditional houses. By the way, it is often simply absent from them. 
Fire hazard of the building
Any building can burn down. To prevent fires, there are now many drugs on the market, including protective agents wooden materials(fire retardant paints and compounds). And of course, follow basic safety measures.
Rodent problems
This minus can also be applied to all houses, even in brick houses There may be rodents. It is worth noting that they do not eat basalt wool and foam plastic.
The need for insulation
A house made of any building material must be insulated in accordance with the prescribed norms and rules.
Stages of construction of a vulture house
Now let's talk in more detail about the construction of a Canadian house.
1. Project selection
Any construction must begin with a project. If you do not pay close attention to this stage, the results of the buildings may turn out to be sad.
In buildings without a design, you can often see a single load-bearing frame, which is responsible for the strength of the structure. Cutting panels is minimized to save time. However, the danger of structures is not taken into account. 
The basis can be any project, since the features of sip panels are taken into account not at the draft stage, but already at the stage of detailed design. Here you need the help of a qualified specialist.
The architectural part of the project outlines the appearance and layout. Independent floor planning can lead to such shortcomings as narrow corridor, steep stairs, etc.
The cost of the finished project varies from 200 to 600 rubles per square meter. How to design a house yourself? You can select a project in any catalog or take published projects on the Internet as a basis and remake them for yourself. Many people do just that.
The construction of two-story houses will be much cheaper than one-story houses with the same area. However, it should be taken into account that the useful space in a two-story building goes under the staircase hall and an additional bathroom.
The main thing is to find the option you like, determine your needs, and compare them with your capabilities. If necessary, change the area, remove excesses.
Studying finished projects, you need to pay attention to the fact that total area is considered differently. Exist different rules calculations, which can distort the final result even by half.
Surely many have wondered how to build canadian house yourself. You will have to use the services of construction organizations in any case.
Panels with the required parameters can be manufactured according to the project. You can of course buy ready-made panels standard size, and then cut them to fit the project. But this is long and labor-intensive work. After completing the order, the panels are transported to the construction site and the assembly of the house begins.
Buying a house kit
There are also now many companies selling house kits created on the “we build it ourselves” principle. This adult building set includes finished frame, which simply needs to be assembled at the construction site; assembly instructions are included.
All wooden components are cut according to the design at the factory, and the buyer receives ready-made, marked products.
3. Foundation
A sip house is considered lightweight, and therefore does not need a heavy buried foundation. Often a strip, pile-grillage, or strip-column structure is erected.
To build a shallow foundation, it is necessary to mark the site and excavate the soil (depth 50-60 cm, width 40 cm). Next stage- this is its compaction.
To do this, sand is poured into a 10 cm layer and compacted. Next, crushed stone is poured using the same principle. Now you can begin installing the formwork, the height is 50 cm above the ground. Before doing this, you must make holes.
After this, it is tied and installed in the trench. The foundation is being poured concrete mortar and dries within a month. The wooden formwork is removed.
A two- or three-layer roofing material is laid on the foundation, onto which it is coated bitumen mastic. Afterwards it is laid in the middle of the foundation and connected at the corners. We secure it with a dowel.
4. Gender
Canadian technologies provide for the complete construction of a house with sip panels (walls, roof, floor). But Russian companies are of the opinion that it is better to make ordinary floors on logs. The space between the joists must be filled with insulation. 
This method is more reliable and durable; you can easily install the floor if an unforeseen situation occurs.
Let's talk about the stages of laying a floor from sip panels.
- To begin with, prepare the bars.
They will also be lags, beams that are inserted between the panels. Their length should allow them to easily lie on the foundation.
- The panels are cut with a saw in accordance with the required size.
If necessary, you can remove the insulation with a thermal cutter. Please note that the gap between the insulation and the edge of the OSP board should not exceed 2-2.5 cm.
- The corner panel is used first during assembly.
- Next, the second panel is attached.
It is pre-foamed, the beam is attached and pressed. Further everything follows the same principle.
- The grooves around the perimeter are filled with boards 2.5 cm wide.
The algorithm of actions is simple: fill the groove with polyurethane foam, insert the board, press it, fix it. Heavy equipment will allow you to lay the resulting structure. The part of the beam that protrudes is secured to the foundation with a steel angle.
5. Walls
The main task is to minimize panel joints, and only after that think about how to reduce waste. 
The lower groove in the two panels is filled with foam and placed on the bench; these panels are installed in the corner and secured with self-tapping screws.
Then the installation scheme is the same: we fill the groove and the bottom of the panel with foam, which we put on the bench, insert a square beam between the panels, press it, and fix it.
After the final installation of the walls, we treat the upper groove with foam, insert the strapping beam there, and fix it with self-tapping screws.
6. Roof
Then to the top strapping bars We fasten the covering beams. The roof can be made of traditional rafters, which will rest on grooves in the beams. Next, the sheathing is filled and the roof is laid.
For attic lovers, we can offer roof insulation. The space between the rafters is filled with insulation and covered with vapor barrier film. On the outside, a waterproofing superdiffusion membrane can be applied to the insulation.
It is much easier to insulate the space between horizontal beams than in walls. In the ceiling, the insulation does not shrink much.
I would like to pay attention to the beams ( wooden frames). Wood is a living material and can become deformed and crack. To avoid these troubles, you should first dry it in the chamber. But this is a budget and not the most reliable method.
The most rational way is to use laminated timber(wooden I-beams, LVL of timber). These materials are several times more expensive, but quality and safety are paramount.
Before laying soft tiles, as well as other roofing, you should carefully consider the ventilation gap. Otherwise, the steam will not find a way out and will entail negative points. Pay due attention to vapor barrier of joints; this can be done with adhesive tape.
We suggest watching the following video to make the above information more clear.
If the roof is planned to be made entirely of sip panels, then installation begins from one edge and builds up along the ridge. First, the first rafters are installed and fixed with self-tapping screws, then the panels are attached using the already familiar algorithm.
Wiring
Separately, it is worth mentioning the installation of electrical wiring. First of all, a diagram is developed, then the markings of the electrical route and electrical points are made. The bases of fasteners for switches, sockets and lighting fixtures must be metal.
In case of using metal pipes or hoses ( hidden wiring) fireproof material is laid between them and the sandwich panels - a box and PVC corrugation. At the bends of the pipe it is necessary to weld or seat on threaded connection. A plastic insert is installed at the edges of the pipes. 
The video below is an example high-quality installation electrical wiring. The disadvantage of the material is its excessive length, however, the authors acknowledge this disadvantage and recommend watching it before 10:27 and after 30:46.
Basic mistakes
At self-construction Sip houses often try to save as much as possible, while making typical mistakes:
- Simplification of the power structure.
Under no circumstances should this be done. Installing floors between floors with long panels, as well as installing floors with solid slabs, will lead to a sad result in the future. The slabs will become loose and begin to creak.
- Total savings.
Saving time and money is, of course, good, but everything should be in moderation. There is no need to build a house from large sections of panels. By saving on timber and cutting parts, you endanger your living in the house.
- Poor quality panels.
This can be the biggest problem when buying panels. You can often find cheap homemade sip panels in hardware stores. They have very poor gluing and such a construction can simply be dangerous.
- Incorrect calculation of the installation gap.
It is also called the dilatation gap; at the joints it should be 3 mm. However, following this recommendation is very difficult. You can simply trim the outer panel if there is a slight discrepancy with the strapping.
In the very general view— building a house and installation technology are not difficult, although they require the well-known “measure seven times, cut once” approach. In general, when compared with other materials and methods, building a house from sip panels can be done easily and quickly; 2-4 people can handle this task.
