The technology of mounting a house from sip panels. Proper fasteners for mounting SIP panels. Foundation for a house from SIP panels

Lightness and big size SIP panels makes this material one of the best for erection country houses. All the main parts for construction are produced at the factory, the required number is brought to the site and assembled like a designer. Big team is not needed for this, the task can be handled by a team of 2-3 people. In addition to the assembly readiness of the material, the simplicity of its docking is also attractive. Consider the key stages of the technology for assembling a house from SIP panels.

What foundation is right for you?

In the case of SIP panels, there is no need for an expensive, powerful base. Finished house on Canadian technology weighs no more than 15 tons, so it is enough to choose an economical strip foundation. In accordance with building codes, the foundation is laid to the depth of soil freezing, in our case, it is enough if corner grillages are laid along the entire perimeter at this depth.

Second stage: floor coverings

You can assemble a house from SIP panels at any time of the year, construction does not have wet stages. Installation begins with the installation of floor slabs. If the span is not more than six meters, standard panels are used for floor coverings. The inside of the panels is insulated with an antiseptic and bituminous mastic.

The joints between the panels are fixed with self-tapping screws and sealed mounting foam. To give the structure rigidity along the horizontal axis, strapping bars are placed in the technological grooves of the ends. Installation of floor coverings can be completed within a few hours.

We mount the walls

Before starting the installation of the first wall panels, a strapping circuit for the walls is prepared. To do this, a longitudinal beam 10 cm thick is attached to the floor with self-tapping screws. The template will help to check the correctness of its placement. The structure is fixed to the foundation with anchor bolts by drilling holes through the panels and timber. All parts must be treated with antimicrobial and water-repellent compounds.

The panels that form the corner are mounted first. The second is placed at right angles to the first. Due to strong fixation corner elements the structure acquires the necessary rigidity. Further, the panels are mounted in series using a tongue-and-groove connection. The connection between the panels is fixed with self-tapping screws or large ship nails.

When all the panels that form the walls of the first floor have taken their places, their technological grooves are filled from above with mounting foam and closed with strapping bars. Simultaneously with the construction of the perimeter, the ground floor space is divided into zones by partitions made of panels. Additional rigidity of the structure is given by the overlap that connects the walls.

The same technological cycle is repeated on the second floor. The ceiling is assembled in the same way as the installation of the floor, the frame of the previous floor serves as a support for it, the floor slabs are attached to it with self-tapping screws.

Attic and roof: no rafters

Roof installation is one of the standard technologies for working with SIP panels. Rafters are not needed during the construction of the roof, the own rigidity of the panels allows them to withstand all meteorological loads.

The lower base for the roof panels is a mauerlat fixed along the perimeter, the upper one is a ridge beam fixed between the gables. The stacked panels are fixed to the beam at the top and bottom with screws. The roof panels are fixed to each other in the same way as wall elements - with self-tapping screws or ship nails.

The attic, located under the roof of SIP panels, will always be warm. The design of the panels is such that the roof does not need a vapor barrier. The roof can be made from any material known today: bituminous, ceramic or metal tiles, others.

Sealing the finished house

After completing the assembly, the structure is sealed, smearing all joints polyurethane adhesive. This is very milestone, the thoroughness of its implementation guarantees long-term operation of the house.

Installation of doors and windows

Openings for doors and windows are provided by the project and prepared at the factory, which greatly simplifies installation.

Exterior and interior decoration of the house

Outside, the house can be lined with brick or siding, clapboard, timber, natural stone or its artificial imitation. The perfectly flat inner surface of the walls is also suitable for any finishing materials: wallpaper, painting, tiling and others. The use of drywall will give the walls additional fire resistance.

Engineering Communication

Communications are laid upon completion of the frame assembly. All of them will be easily accessible due to the external location. If necessary, they are covered with plasterboard partitions or suspended ceilings. Plumbing and sewerage one-story house do it under the floor two-story building arrange special mines. Distinctive feature construction using SIP - flexibility in terms of communications. All wooden elements, which will be in contact with the water supply and sewerage, are additionally impregnated with waterproof compounds.

Factory production of all elements, the lightness of the panels makes possible mounting in the shortest possible time.

Advantages of houses made of SIP panels compared to houses made of traditional technologies construction are obvious:

• Strength. The sip panel can withstand up to 200 kg of load per 1 m 2 with a deflection of no more than 12 mm.
• No shrinkage and smooth walls. You can attach to the exterior and interior decoration immediately after installation.
• Increased fire resistance. Temperature range -50ºC to +50ºC
• Ease of construction. Average weight Canadian technology houses
  no more than 15 tons.
• Increased heat capacity. For home heating SIP technologies 4-6 times less resources are needed than for heating brick.

Watch the house assembly process in the video:

Deciding to build a private house himself, often the emphasis is not so much on the quality of materials, but on their cheapness. Currently the most profitable and fastest way to build- construction of houses from sip panels.

Panel building gained popularity over 50 years ago. Initially this technique established itself in Canada, Europe, Japan. Today, the technology has gained many supporters among Russians.

Types of material: what are they made of?

SIP is a structural insulating panel consisting of two special sheets, between which a heater is placed.

Layers stick together under pressure With high pressure. The standard plate thickness is 9 mm or 12 mm.

Let's see what sip panels are made of?

outer layers can be made from the following materials:

• oriented strand board;
• a sheet of gypsum fiber or drywall;
• plywood;
• fiber board.

As a heater is used:

• polystyrene foam - a porous material that is 90% air, is absolutely safe;
• polystyrene - waterproof, but flammable, subject to rapid burning;
• polyurethane foam - has a high insulating threshold, does not conduct heat, is flammable;
• mineral wool - does not burn well, is safe for health.

In this article, you can learn about what a roof gable is and what it is for.

Advantages and disadvantages

sip panels have significant advantages:

The disadvantages of sip panels are the following:

1. not safe- First of all, it depends on the quality of the materials used in production. Many factories make panels using foam. It is better not to buy them, polystyrene releases formaldehyde.
2. Condensation forms at the junction of the frame and the plate, which leads to the appearance of joint defects.
3. The panels are hermetically sealed, therefore, buildings need compulsory system ventilation which increases the cost.
4. The service life is limited. The design loses its insulating properties after a few years. This problem is solved by replacing the worn-out insulation with a more durable polystyrene foam.

How to build a house from sip panels with your own hands?

Today, in the construction market, a huge number of companies are building houses from sip panels. Of course, you can build a house with your own hands.

Consider phased implementation works. So, we are building a house from sip panels with our own hands.

Preliminary work

At this stage, a project of the future dwelling is drawn up. Usually, suitable option choose from many standard projects and improve on their own.

Or they turn to the design organizations for help. Thoughtful planning ensures quality and durability of the future home.

Then produced calculation of the required amount of material, purchase quality tool(you will definitely need a screwdriver, a hacksaw). Seek help specialized organization will most likely have to.

Buying standard panels and then customizing them for your project is quite laborious. Consequently, it is easier to contact a company that will manufacture and deliver panels required parameters.

Foundation construction

most popular foundation types are:

• pile or pile-tape;
• monolithic slabs with shallow penetration;
• columnar or columnar-tape;
• tape deepening with a plinth;
• tape recess.

Piling installation has a relatively low installation speed, simplicity, efficiency and economy. Most experts consider piles to be the most acceptable basis for a panel house.

Screw pile is metal tube with a blade. The pile is screwed deep enough into the ground, which eliminates the deformation of the building.

Water supply, heating and electricity for the future home bred to the construction of the foundation.

Waterproofing, piping, building walls

At this stage, two layers of roofing material or bitumen are laid on top of the foundation, and then a strapping beam, pre-treated with an antiseptic. Then, starting boards are attached to the strapping beam with screws.

Panels are laid next, which will later serve as a floor. When docking, the grooves are treated with sealant, fixed with self-tapping screws. Butts also treated with sealant, sheathed with boards.

The sip panel is attached to the launch board. It should be mounted from the corners of the structure. The connection is simple, the groove is inserted into the ridge, the fasteners are reinforced with screws.

Be sure to use a level to protect the structure from distortion. For joints, foam is used. It is also worth doing with the ends of the sip panels before joining them to each other.

A sandwich panel is a design that consists of a heater and a few words roofing material and is used as the main construction material for the construction of buildings of varying complexity of design. For the manufacture of sandwich panels, only proven and suitable materials are used. The main material for the cover layer is usually "corrugated board" (galvanized steel coated with a polymer).

Heaters

When choosing sip panels, it is still better to seek help from specialists. But if this is not possible, it is worth studying the main types of heaters and their characteristics.

There are three main types of heaters:

• polystyrene (polystyrene foam);
• mineral wool ( basalt insulation);
• polyurethane foam.

And each of these heaters has its own advantages and disadvantages.

Polyfoam is positioned as a heater, distinguished by its durability. In addition, it is an environmentally friendly material. Possesses properties of water resistance and is not afraid of the sun. But at the same time, such material is very flammable and burns quickly.

Mineral wool practically does not burn and is also harmless to health.

This insulation also tolerates biological and chemical effects well. But with a set of such important advantages, basalt insulation has a very low resistance to moisture.

Polyurethane foam is a poor conductor of heat and is easily flammable, but it has a high insulating threshold.

The thickness of the building material, and, accordingly, the price directly depends on the thickness of the insulation itself.

The issue price of the SIP panel is 1,300 rubles per square meter. Its thickness is 174 mm, width is 1250 mm, height is 2500 mm.

In our country and the CIS countries, sandwich panels of the following sizes are used:

12+100+12=124 mm;

12+150+12=174 mm;

12+200+12=224 mm.

OSB (OSB)

Introduction to the concept OSB boards you should start with general classification. There are four main types of OSB. Each of them differs from others only in its indicators of moisture resistance and strength.

• OSB 1 is a board with the lowest moisture resistance strength. This type of plate is often used in the assembly of light weight parts. The advantage of these plates is their low price.
• OSB 2 - has a low moisture resistance threshold and at the same time high strength. Such plates are used mainly for the production of furniture, sometimes for load-bearing elements. Less commonly, OSB 2 is used in the construction industry, and then only for internal structures.
• OSB 3 is one of the most popular types plates. These boards combine strength and moisture resistance at a nice price. They are used more often in construction for the construction of both facade and interior finishes. Sometimes OSB 3 acts as a roofing material or floor.
• OSB 4 - these OSB boards have the most high threshold strength and moisture resistance. They are used to build structures high level loads and in areas with high humidity.

Construction of houses from sandwich panels: advantages and disadvantages

Like any material, the use of sandwich panels has both advantages and disadvantages.

First about pleasant. The main advantage of this building material is the conformity of its quality, which is evidenced by the high strength of the material, relative to the price. This factor plays a very important role in the calculation construction estimate. After all, the use of this material significantly reduces costs. Due to the lightness of the panels, the weight is lightened general design, which means that there is no need for a reinforced foundation.

See more projects of houses in the section "Projects of houses" on our website.

Do-it-yourself sandwich-panel house

The first thing that will be needed in this matter is the project of the future building. Should be given Special attention to its construction, not forgetting about the requirements and wishes. If it is not possible to build it yourself based on the complexity of the calculations, then there are a lot of companies ready to help in this matter. We will try to show you all the stages of construction in a photo report, with step by step instructions. But, all houses are individual, our photo can only be considered as an information guide.

By the way, not only houses, but also extensions to residential buildings can be built from SIP panels. They can accommodate verandas or kitchens.

The next step is to order SIP - panels or their independent production. You can order them directly at the enterprise that is engaged in production. Here you can also view catalogs and choose everything you need for subsequent installation. When choosing panels, do not forget about the foundation - the foundation. For a structure made of such material, usually, the foundation is installed on screw piles.

Water supply, heating and electricity for the future house must be diluted even before the foundation is poured.

To avoid curvature of corners or mismatch in height, all panels must be checked for integrity and dimensional conformity before installation. If inaccuracies are noticed, contact the supplier for a replacement material.

After the foundation is poured, you need to make it strapping with wooden beam. Then the corners are set and with the help percussion instrument holes are made. Using these holes, the beam is fastened to concrete with 12 mm anchors. Recommended distance 2.5 m. Further, the building itself is assembled on the established foundation. The assembly is started with a zero overlap, while the first SIP panels are laid on the timber.

Wall frames are assembled from timber. A mortgage board is fixed along its perimeter with special nails. The main thing here is to maintain vertical calibration and frame angles. After all, if you miss at least 1 mm somewhere, the wall will turn out to be a curve and there will be no possibility to correct it. After installing the frame, panels are applied to it.

After the construction of the general structure, the sealing of the holes begins. The joints and corners of the panels are filled with edged boards 25 * 100 mm in size. All cracks are sealed with foam.

Ceilings between floors and all bearing structures it is better to make wooden. You can use both timber and boards. Photos of the stages of construction are just below.

Foundation for a house from SIP panels

The foundation is, first of all, the foundation of the building. It transfers the entire load of the building to the underlying soil layers. In addition to the strength of the foundation itself, you need to consider:

• the total area of ​​​​support on the soil;
• the support capability of the soil itself;
• groundwater levels.

Experts consider the excessive abundance of concrete and metal in it to be the most common mistake when pouring the foundation.

by the most popular species foundations are:

• pile (pile-tape);
• columnar (column-tape);
• monolithic shallow slabs;
• tape deepening;
• tape deepening with a plinth.

But, it is worth noting that among this variety, for wireframe panel houses the best option would be shallow penetration.

Laying a strapping (crown) beam

For laying, a timber with a size of 2.5 * 1.5 cm is taken. Laying should begin from the middle of the foundation, while measuring its horizontal calibration. Next, the beam must be connected at the corners with a notch. After that, the details are fixed. For correct fastening holes are drilled in the timber with a length of 1–1.5 cm with a diameter of 2 cm and a dowel is driven in.

The fastening of the beam to the foundation is done with the help of anchor bolts with drowning. The fastening distance is about 1.5–2 m. The size of the bolts should be 35 cm long with a diameter of 1–1.2 cm.

Arrangement of the floor in the house from SIP panels

Another proof distinctive property Canadian construction technology, is the technology of arranging the floor.

Floors and ceilings are also built from SIP panels.

Although many contractors recommend laying ordinary wooden floor with insulation between the lags and beams. These floors are reliable and more durable. In addition, this floor will be easier to disassemble or repair.

Building walls from SIP panels

When building walls, you need to carefully choose source material, because the quality of the future home largely depends on its quality. The best option for outdoor work there will be a beam with a diameter of 15 cm. As for the height, here is a minimum of 1.5 m. For the inside, 10 * 15 cm is suitable. These are acceptable sizes that will help save on consumable, will minimize the number of seams and joints and achieve perfect smoothness of future walls. Assembling the walls is not easy, you need experience.

Before laying the timber in the crowns, all materials must be adjusted in accordance with the height and give them the desired shape. For corner connections it is better to use the “half-tree” or “tied with a root spike” method. Connections of the outer parts are best done with a cut or on veneers. And it is better to connect the internal sections of both joints and corners with a half frame.

To begin, direct installation is necessary with the laying of a crown beam treated with an antiseptic agent into the foundation.

Arrangement of the roof in the house from SIP panels

The roof for a house built using this technique can be the most common truss. This type of roof is characterized by support in the form of grooves or Mauerlat, which are cut into beams on attic floor. The rafters are installed on the supports, the crate is stuffed on them and the roofing material is laid.

As for insulation, for a cold attic there is no need for it. But if the plans are to install an attic, then it is worth putting a heater between the rafters and covering it with a vapor barrier film.

In addition to the truss, no less popular is the roof of SIP panels. For this type, the first step is to install the starting rafters, which are bolted to the Mauerlat. And only after that comes the laying of the panels. The panels are mounted on one side of the roof, gradually increasing the height in length with the ridge. As soon as work with the first skate is completed, you can proceed to the next one.

This installation method is more painstaking than traditional, but no less reliable.

Facade decoration

Facade finishing is the final stage of construction. Each owner makes it according to his taste and financial capabilities. Among the finishing options are now very popular: facing brick, siding, decorative plaster.

look interesting video about building a house from SIP panels.

A new material type is always associated with a good indicator durability, strength, availability. There is something to compete with, so manufacturers of SIP panels create a building material from which a residential building can be assembled in a few days. And for such work, cranes, tractors and concrete mixers on wheels are not needed.

All work is done on the assembly of the house at the expense of manual labor 1 brigade. Let's analyze it step by step construction processes from such interesting material.

We are preparing the foundation

A house made of SIP panels must be placed on an already dried foundation.

Need to know what future design not heavy, suitable type:

• Columnar;
• Tape;
• pile;
• Screw.

The basis on piles is more profitable, because the house can be built on any soil.

Even if there are further problems with the soil, the building will not be damaged. Pile foundations are also mounted very quickly, in one or two days.

About installation column foundation. About the strip foundation.

How we build a house

Please note that houses from SIP panels are assembled according to the project or instructions. Parts or structures are delivered to the object already in finished form.

They comply the right dimensions There are openings for windows and doors. The number and dimensions of SIPs are calculated and ordered several months in advance, so that later there are no delays during assembly. This is what savvy customers do.

Another situation is when the owners of future buildings want to work with their own hands. They take over the assembly, but are required to submit documentation for the preparation of SIP panels. It does not happen that right during the construction of the facility, the preparation of a new element begins.

We start construction

SIP structures are assembled with a base. This element is located on the foundation. The classic look is a timber construction. The base is assembled like this:

• Make strapping around the entire perimeter of the future structure;
• The crossbar is mounted. They must rest on pillars or pillars of the base.

The classic technology for assembling a house from SIP panels involves assembling the floor. So faster, there will be no waste of materials. There may be drawbacks, but there are no analogues in terms of speed.

Let's assemble the walls

The first floor begins with the installation of the uterus or guide rail. It is mounted to the base with anchor bolts. Here you need to work and measure very carefully. If you make mistakes, then snacking on future walls of SIP panels is possible.

Let's assemble the walls according to this scheme:

• We start from the corner of the first floor. Initially we put the panel. Then we securely fix it to the already fixed beam on the foundation. Any actions are checked by constant changes.
• We are engaged in the installation of the following SIP panels, which must be placed at an angle of 90 degrees. The seams of the connection of the planes must be foamed immediately. The angle must be ideal, since the direction is set from it, this is a guideline for the installation of the following parts of the structure.
• We collect the remains of the walls, put the prepared SIP panels. Here is the thorn-groove technology. Each of the elements is mounted on a guide beam, and is grasped between each other thoroughly due to self-tapping screws.

We see that such an assembly scheme is quite simple. A lot of time is spent on control and additional measurements, but in terms of installation there is nothing complicated. When we connect SIP elements, it is necessary to maintain right angles.

We complete work on the first floor with mounting foam. We process the entire perimeter with it, all the seams, the strapping. Foam adds practicality, often acting as a marker for installing SIP elements at the top.

About the roof

When the roof frame is also planned to be assembled from SIP panels, there is no need to worry about rafter system or other structural features. All the strength of the frame is already in the prepared roof panel. When they start building, they put a beam along the perimeter future roof, only it is fixed to the trim of the finish floor.

It is not difficult to assemble a roof from SIP panels, it is done like this:

• Assemble the pediments. The process is the same as with the installation of floors. You need to work without haste, constantly measure the corners.
• Before lifting the panels, it is necessary to install a beam, which will be a support.
• Further on the strapping and the above timber are mounted in the panel, then they are qualitatively fixed with anchors.

Any part of the house is built according to the same algorithm. Let the panel be quite strong, sometimes some corners or areas need to be reinforced with a connecting board, then this material will give rigidity, good resistance in case of natural disasters.

Results

The most simple technology when compared with any other modern approaches. Described the technique classical type, where the main skill of the installer is attentiveness and accuracy.

It is important to remember about the foam, the processing of gaps between the shields. And, by the way, it is better to use waterproof polymer glue.

No mention was made of internal partitions. Everything is the same here, only the SIPs themselves are slightly thinner. There is no need to use connecting boards indoors because the fastening system is sufficient for this part of the facility.

SIP panel is a building material, inside of which there is a layer of insulation, and the outer part is a layer of OSB.

Heaters

Inside the panel can be located different types heaters, each of which has its own advantages and disadvantages:

1. Styrofoam (durable and environmentally friendly, waterproof, UV-resistant, but not fire-resistant).
2. Mineral wool (almost does not burn, but at the same time does not have a harmful effect on health, is resistant to external factors, except water and moisture).
3. Polyurethane foam (practically does not conduct heat, but burns quickly).

The panel can be different thickness, which directly depends on the thickness of the insulation used. Standard sizes SIP panels (H*W*D): 174*1250*2500.

For the construction of walls of houses, OSB-coated material is often used. Moreover, there are 4 types of OSB boards, which differ in terms of strength and moisture resistance:

• 1 - First class plates are the cheapest, but are not suitable for mounting parts that will be under serious stress. The moisture resistance of these boards is also low.
• 2 - The moisture resistance of these boards is also low, but the strength is much higher compared to the first class. When building houses, such panels can only be used for mounting internal structures.
• 3 - The optimal class of slabs for building houses. They are ideal for building facades and for internal partitions. In the construction of small low-rise buildings, they can be used even in the construction of floors and roofs.
• 4 - Durable and moisture resistant material that is suitable for building houses in difficult conditions regarding load and humidity.

Advantages of houses from SIP panels

Due to the following advantages, the construction of houses from SIP panels is gaining popularity:

1. Savings on the foundation, due to the low weight of the panels.
2. Cost optimization due to the low cost of the material relative to other types of building materials.
3. Ease of installation, thanks to the lock assembly, evenness and large area of ​​the panels.
4. External and interior decoration are also made easier.

Flaws

1. Sip panels based on foam and mineral wool not as durable as polystyrene based panels. With time beneficial features sip panels are reduced.
2. In houses it is necessary to provide high-quality ventilation.

Building project

Buildings from SIP panels are built according to a finished project, equipped with calculations and drawings. Finished project can be ordered from a specialized company, where you can also order the construction of the house itself or rely on your own strength.

Then you should order required amount SIP panels, preferably with a small margin. Do not forget about the various structural elements and supporting materials. All elements after delivery to the site are checked for compliance with the characteristics, in particular, integrity, dimensions, evenness.

Assembly order

Sip panels are lightweight, so the installation of panels does not require the help of heavy construction equipment.

	First of all, proceed to the installation of the foundation. Ideal for SIP panels screw foundation. But the final decision on the type of foundation is made depending on the characteristics of the soil, terrain, and the wiring of communications (water supply, electricity, heating) must be done even before the foundation is poured, laying structural elements. Having completed the construction of the foundation, it is necessary to make a strapping from a wooden support beam. After checking all the parameters with a level, setting the corners, in concrete surface of the foundation, holes are made with a puncher and the beam is fixed with 12 mm anchors at a distance of 1-2 m from neighboring fasteners. Each beam must have at least 3 fasteners. If a grillage is made from a wooden beam, it is necessary to tighten its structural elements with M10 studs at a distance of 30 cm from each pile.
	In this case, irregularities may form, which are eliminated with a planer.
	On the piles, under the grillage, it is necessary to put pieces of roofing material. Then the grillage is attached to the piles using M10 studs.
	Under the nuts and washers make recesses.
	After installation, the timber is treated with mining or bituminous mastic. Then, in order to protect the wooden elements from damage, the lower part of the floor panels is treated with the same substance.
	The assembly of the house begins with the laying of the first floor - the first panel is placed on the strapping beam and fastened with self-tapping screws to the strapping beam.
	The end of the panel is moistened with water, foamed.
	Install a connecting beam (lag).
	Fix it with screws.
	The outer ends of the panels after assembling the first floor are moistened with water, foamed and the board is installed - fixed with self-tapping screws.
	Before installing wall panels, it is necessary to fix the mortgage board. It is treated with foam and installed around the perimeter of the ceiling.
	Fix it with self-tapping screws 280 mm.
	Then the first wall panel is mounted. On both sides, the panel is fixed with self-tapping screws to the mortgage board.
	The verticality of the installation must be leveled. Before installing the second wall panel you need to fix the connecting bar. Joints must be foamed. The panel itself is attached to the beam with self-tapping screws.
	Corner panels are pulled together with Spax 240 mm self-tapping screws or “wood grouses” in increments of 15 cm. Interior partitions are installed in the same way.
	After Assembly interior partitions proceed to the installation of the ceiling - install the beams, creating a temporary fastening with self-tapping screws. A beam support is installed in the flight of stairs.
	OSB sheets are laid on the beams and fixed according to the instructions.
	Further assembly of the house is carried out similarly to the first floor.
	The ends of the walls adjacent to the gables should be sawn at an angle. Then the beams are installed on the gables. The beams must also be sawn, according to the slope of the roof.
	Install the ridge bar.
	Cut it out at the required angle.
	The ends of the gables before laying the panels are covered with sealing material.
	After the erection of the walls and the installation of the beams, they proceed to the installation of the roof. This is done according to the drawings, taking into account the markings on the panels. If the roof extension is small, then first the first panel is laid on the gable with a length slightly more than the width of one roof slope, the second is positioned so that it rests with the long side on the gable, and the short side on the first panel. If a significant roof extension is provided, then the extreme row is made up of small panels, between which are inserted additional bars, and corner panel should consist of two triangles to insert the timber diagonally.
	Between themselves, the panels are fastened with a connecting beam, and the ends are covered with a board. On the ridge, the panels are fastened to each other.

Thus, houses are assembled from SIP panels. All work (depending on the size of the house) is carried out in a matter of days.
