Turnkey sandwich panel house project. House from sandwich panels - we build ourselves, quickly and reliably. Decorative or finishing sandwich panels

A sandwich panel is a structure that consists of insulation and a few words of roofing material and is used as the main building material for the construction of buildings of varying design complexity. 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 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 SIP panels is 1,300 rubles per square meter. Its thickness is 174 mm, width - 1250 mm, height - 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 should start with a 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 board types. 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 highest threshold of 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 its own 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 calculating the construction estimate. After all, the use of this material significantly reduces costs. Due to the lightness of the panels, the weight of the overall structure is lightened, 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. Special attention should be paid 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, SIP panels can be used to build not only houses, but also residential buildings. They can accommodate verandas or kitchens.

The next step is to order SIP panels or them. 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, you need to make it strapping using wooden beam. Then the corners are set and holes are made using a percussion tool. 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 supporting structures are best made of wood. 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.

The most popular types of foundation 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 proper fixing, holes are drilled in the timber in a length of 1–1.5 cm with a diameter of 2 cm and the dowel is driven.

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 of the distinctive properties of Canadian construction technology is the flooring technology.

Floors and ceilings are also built from SIP panels.

Although many contractors recommend laying a regular wooden floor with insulation between the joists and beams in such houses. These floors are reliable and more durable. In addition, this floor will be easier to disassemble or repair.

Building walls from SIP panels

When erecting walls, you need to carefully choose the 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 consumables, 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 joints, it is better to use the “half-tree” or “tied with root tenon” 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 the beams on the attic floor. The rafters are installed on the supports, the crate is stuffed on them and laid roofing material.

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 finishing

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 bricks, siding, decorative plaster.

How to build a house so that it is inexpensive, warm and prefabricated? To accomplish this task, you can use the design of the sandwich panels. Sandwich panel is a building material, which is a slab consisting of three layers.

The middle layer is insulation. It can be polystyrene foam, polyurethane foam, mineral wool or fiberglass. The two outer layers are metal, thermoplastic vinyl chloride polymer (PVC), fibreboard (Fibreboard) or magnesite board.

The use of sandwich panels ensures a high speed of work on the construction of the building. In order for the assembly speed to be maximum, it is necessary to design the building with high quality. With the finished project, you should contact the panel manufacturer. According to a given project, all blocks will be made individually. After that, it will not be necessary to adjust the joints during installation.

House building technology

To start building a house from sandwich panels, you need to purchase the necessary tools:

• screwdriver;
• drill;
• syringe device for applying construction foam;
• building level;
• paint brushes for applying mastic;
• panel saw.

Construction begins with the construction of the foundation. A house made of sandwich panels is lightweight, so a monolithic strip shallow foundation or a foundation on screw piles with a wooden grillage is suitable for it. Before arranging the foundation, communications should be laid: sewerage, water supply and electricity supply.

Fastening panels to reinforced concrete structures. Option number 1: 1. Wall panel. 2. Flashing. 3. Self-tapping bolt. 4. Thermal insulation. 5. Self-tapping screw. 6. Silicone insulation. 7. Seal.

A wooden strapping beam with a section of 100 x 150 cm is laid on the foundation. Before laying, the foundation is smeared with bituminous mastic for waterproofing. The beam is attached to the concrete with anchor bolts, recessed into the foundation by at least 10 cm. In the corners, the beam is connected “in a paw” or “half a tree”.

Along the entire length of the timber, anchor bolts must be additionally provided for fastening in increments of half a meter. The heads of the bolts or their ends with nuts must be completely recessed into the tie bar.

The floor is proposed to be mounted in two versions. In the first version, the floor is made as usual: boards are laid on the logs, and insulation is laid between the logs. The logs are installed with support on the strapping beam and are connected to it “half-tree” in such a way that their level coincides with the level of the strapping beam. With this option, it is easier and more affordable to make repairs in the future.

The second option suggests using the same sandwich panels as the floor. They provide adequate insulation. In this variant, beams are used, which are both lags and spiked beams that form a connection between the panels. The cross section of these beams depends on the dimensions of the sandwich panels and is available in two versions: 150 x 50 mm or 200 x 50 mm.

Fastening panels to reinforced concrete structures. Option number 2: 1. Wall panel. 2. Flashing. 3. Self-tapping bolt. 4. Self-tapping screw
5. Silicone insulation. 6. Seal. 7. Supporting corner. 8. Self-tapping screw.

The floor boundaries in the second option will coincide with the contour of the strapping beam along its outer edge. The panels are laid out on a strapping beam and cut to the desired size. Trimming can be done with a regular saw. Then the panels are placed on the edge and on one of the sides, which will be at the bottom when laying, bituminous mastic is applied.

If it is required to remove the insulation from the end of the panel, then a thermal cutter is used. The thermal cutter is sold complete with sandwich panels. It can also be made independently. The principle of operation of the thermal cutter is based on the manufacture of a tubular electric heater - a heating element. It looks like a rectangular frame with a side of 150 or 200 mm. The frame should have a limiter for the depth of immersion in the end of the sandwich panel.

The panel groove is filled with building foam, a beam is inserted into it and pressed for a few seconds. The beam in the panel is fixed with self-tapping screws or wood screws in increments of one and a half decimeters. Further, from the side of the beam, a second panel is attached with preliminary foaming.

The grooves remaining along the perimeter of the floor are tied with boards 2.5 cm thick. The entire floor along the perimeter is attached to the strapping beam with long screws. On the surface of the floor, it will be possible to lay a warm floor with electric or water heating in the future. Sandwich panels are strong enough to withstand furniture and other indoor furnishings on the floor.

Further along the perimeter of the floor, a strapping board is laid, which is a beam with a cross section of 150 x 200 mm, on which the walls are mounted. The dimensions of the board depend on the thickness of the sandwich panels. The first wall panels are mounted from the corner. Installation of panels is checked by level. The fastening of the panels to each other is done in the same way as on the floor. When all wall panels are installed, a strapping board is installed in their upper common groove.

Fastening panels to reinforced concrete structures. corner option: 1. Wall panel. 2. Flashing. 3. Self-tapping bolt. 4. Thermal insulation. 5. Self-tapping screw. 6. Silicone sealant. 7. Seal.

To reinforce the floor structure, additional beams are installed using mounting brackets or brackets. Overlapping can be done according to the same principle as the floor, using sandwich panels. On top of the ceilings at the ends of the building, a pediment is installed, which structurally consists of the same sandwich panels. The roof is trussed.

The gable roof rests on the end gable of the building. A ridge beam is laid at the top of the pediment, which has bevels made at an angle that provides the necessary slope. Parallel to the ridge beam, additional load-bearing beams are laid in the grooves on the pediment. The lower part of the slope does not rest on the wall, but on the Mauerlat. This is a beam that fits on top of the wall and rests on a groove in the pediment of the building.

An attic roof made of sandwich panels is laid on the ridge beam, load-bearing beams and mauerlat, as well as the floor and walls. The rafters in this design are at the same time beams connecting the panels to each other. For windows in the walls, openings in the construction of sandwich panels should be provided. Openings can be cut into a solid mounted wall. Windows are standard.

In rainy weather, work should not be carried out, because the ends of the panel cuts are not protected.

Prefabricated houses and other structures made of special sandwich panels have gained popularity in the current construction. Block buildings have proven themselves with better side in the construction of residential premises and in the construction of shopping and sports centers, markets, hangars, warehouses, etc. Buildings made of such material are economical and have a number of other advantages. There is an opinion that this material will become massive in modern and future construction.

The best reviews of sandwich panel houses come from users

Perfectly proved themselves in the construction of sandwich panels. This one is from several layers (3-4). Rigid sheets are installed on both sides different materials(galvanized metal sheet, PVC, OSB or fiberboard sheets, magnesite tiles). One or more layers of filler are laid between the layers. All component parts are glued together with polyurethane adhesive, consisting of several components.

Cold or hot pressing of all components provides finished blocks of sandwich panels. Both outer and inner balls of such products are made of various materials. Moreover, the construction industry is constantly improving, using all new materials as components, and sometimes a combination of different fillers.

When completing building sandwiches, they most often use:

• mineral wool;
• polyurethane foam;
• polystyrene foam;
• fiberglass;
• polyisocyanurate foam.

Excellent reviews about houses made of sandwich panels exist among builders and owners of such buildings.

Positive feedback on prefabricated houses

Often, in the vicinity of large cities, literally in a few months, cottage settlements built in a block way grow up. Such buildings have positive reviews of prefabricated houses among developers and consumers. This type of construction is suitable for the investor due to the cost-effectiveness and speed of construction. Residents are satisfied with the properties:

• excellent thermal protection;
• incombustibility;
• aesthetics;
• ergonomics;
• good sound insulation, etc.

Benefits of building from prefabricated blocks

The biggest advantage of building structures from block systems is the speed of erection. Residential buildings are being built at a certain capacity. Large shopping centers, bus stations, airports have a fundamental basis. All reviews of sandwich panel houses are positive. Small and temporary structures of warehouses, hangars, construction change houses can be installed without a foundation. In a few days, such a structure can be dismantled and moved to another place. Such movement is also an advantage of block construction.

Compared with capital construction from and similar materials, buildings made of sandwich panels are very economical and easy to use, easy to transport and install. They provide excellent thermal insulation and sound protection. Many units contain non-flammable or only fusible fillers, which will prevent fire and serve as a permit from the fire services to put the facility into operation. Therefore, there are excellent reviews about prefabricated houses from consumers.

Variety of sandwich panels

The most common in housing construction are. They include OSB chipboards on both sides, and between them - polystyrene foam insulation. This composition of components for housing construction has the most best reviews about prefabricated houses. In commercial construction, sandwich blocks are most often used, having a base made of galvanized sheet on both sides. For such blocks use a profiled or conventional a metal sheet from 0.55 mm to 1 mm thick. Insulation in this case is most often mineral wool or other fillers. The main thing is that reviews of houses from sandwich panels have no complaints.

Plasterboard sandwich panels

Recently, sandwich panels have become popular, the surfaces of which consist of gypsum boards. Rigid polyurethane foam or others are used as a filler. Partitions are installed from such blocks in residential buildings and other premises. This material can be separated workplace storekeeper from the space of the entire warehouse. Many stores that rent certain square meters, separate the space with the help of such plasterboard partitions.

Cons of building a residential building using new technology

Summing up, I would like to note that, as in any field, this technology has its drawbacks:

1. Difficulties in finishing. Not every finish is applicable for this type of construction. Concreting, plastering and gating will have to be excluded. It is recommended to lay electrical wiring on top and sheathe the walls with drywall, install suspended or stretch ceilings.
2. You need to carefully select a reliable panel manufacturer, otherwise you risk ending up in a new, but cold or damp house.
3. It is necessary to strictly observe the construction technology. Most often, prefabricated houses suggest, the assembly of which has its own characteristics.
4. The subsequent sale of a residential building made of sandwich panels can also cause difficulties due to the lack of awareness of citizens and the experience of living.

In today's turbulent world, where time has acquired an unprecedented value due to the fact that it is constantly in short supply, and you want to get results immediately and immediately, even in building technologies and materials, speed of execution, low cost and minimal operating costs have come to be valued. That is why those seeking to quickly move to their own separate housing increasingly prefer to build houses from sandwich panels. Such houses are built literally in a matter of days at any time of the year, quickly warm up and keep heat well, which reduces heating costs, have good sound insulation, and most importantly, their construction is very cheap. Let's figure out what a sandwich panel is, is it worth building such a house and how to do it yourself. Babushkinsky district of Moscow is a great place to live.

Construction of houses from sandwich panels: advantages and disadvantages

Recently, advertising of houses from sandwich panels has not stopped for a minute. From each iron we are assured that these are the strongest houses in the world, everything around is collapsing, and the panel buildings remain intact, that they are the warmest and most economical, do not deform or sag, and in general - it is simply impossible to find anything better. But the most absurd thing is something else: you can often find ads like this: “We are building houses from sandwich panels. ECO housing for ridiculous money”, etc. So - a house made of SIP panels is by no means environmentally friendly and harmless to health. The only reason why such a house can be called ECO is that by living in it, you can save on heating, which means saving natural resources. Those. ECO from the word "savings". Let's see, nevertheless, what are the advantages of the technology of building houses from sandwich panels and what are the disadvantages.

Benefits of houses made of sandwich panels:

• Very fast build. The box at home is easily mounted within a week or two.

• Can be built at any time of the year. There are no limits on building temperature.
• thin walls, due to which the usable area inside the building increases.
• Excellent thermal insulation. They warm up quickly and perfectly retain heat, since the lion's share of the thickness of the walls is made up of insulation.
• Do not shrink or deform. You can proceed to the internal and exterior finish immediately after the construction of the building, and then immediately call in and live.
• The material of the sandwich panels perfectly soundproofs.
• The walls are strictly vertical and even. It is very easy to install the panels in a vertical position.
• You can save on heating.
• No reinforced foundation required.
• durable. Withstand hurricanes.
• Sandwich panels are easy to transport and assemble as a constructor.
• cheap. The price for a house made of sandwich panels is the lowest - and this is the most significant plus of this technology.

As you can see, the list is rather long, but there are also limitations:

• fragility. The service life of sandwich panels is not as durable as wood, brick or concrete. The maximum is 25 - 30 years. Although the stated period is 50 years, let's face it and take into account our climatic conditions.
• The strength of such a house is very relative. Maybe he can withstand hurricanes, but cutting a hole in the wall with an ax will not be difficult and does not take much time.
• Absolute non-environmental. Sheathing sandwich panels made of OSB (Oriented Strand Board), which uses a resin binder and other additives. And the inner filling is a heater, for example, polystyrene foam is an absolutely synthetic product. Like it or not, but all this during operation emits not the most “pleasant” substances. On the other hand, there are people who build houses from fixed formwork from the same polystyrene foam or simply insulate their houses with foam plastic, so this is everyone's choice. I like to live in a thermos, no one can forbid it.
• Absolute tightness. To create normal living conditions, the arrangement of forced supply and exhaust ventilation is required. Otherwise, the movement and renewal of air simply will not occur. And these are additional costs that offset the cheapness of construction.

• Sandwich panels are on fire. All statements that the material has a flammability class G1, we will leave on the conscience of the manufacturers. Not only do they burn, but in addition, during combustion, polystyrene foam turns into a liquid state and simply drips or pours “rain from fiery lava” from above. We will keep silent about the fact that in the process of burning OSB boards and polystyrene foam any poisonous muck is released.
• Require a special type of heating system - air. You can, of course, install the usual one for us - radiators under the window, but it will not be practical due to the complete tightness of the structure.
• Due to improper operation and lack of proper ventilation in the panels mold, fungus can form.
• When selling such a house, it cost will be much lower than brick.

Now the choice is for everyone, to build or not to build. Of course, the low cost of a house made of sandwich panels is a significant argument, which is why such houses are often built in dachas for temporary residence. If you decide that you need just such a house, let's understand further.

Meet SIP panels (sandwich panels)

SIP(Structural insulated panel) or sandwich panels are a three-layer material.

As outer layers used durable sheet material: OSB (Oriented Strand Board), Magnesite Board, Fiberboard (Fiberboard), Wooden Boards. The thickness of the plates is 9 mm or 12 mm. Most often in SIP panels for the construction of houses, OSB-3 (OSB-3) slabs 12 mm thick are used, intended for use in load-bearing structures at high humidity.

core sandwich panel is insulation: expanded polystyrene, polyurethane foam or mineral wool. The thickness of the material varies according to the needs of the customer and can be from 50 mm to 250 mm. Most often, expanded polystyrene PSB-25 or PSB-S-25 with a density of 25 kg / m³ is used.

The outer layers are bonded to the core under high pressure. The result is a new durable composite material.

In the CIS, SIP panels of various sizes are used:

12+100+12=124 mm;

12+150+12=174 mm;

12+200+12=224 mm.

OSB (OSB)

OSB (Oriented Strand Board) or OSB is made from wood chips with a diameter of no more than 0.6 mm and a length of no more than 140 mm. The chips are laid in three layers perpendicular to each other, a waterproof adhesive resin is added and the material is pressed under high pressure and temperature. The result is a material with increased flexural strength and increased elasticity. The surface of the OSB boards is waterproof, and the boards themselves are easily sawn with any wood tool. Distinctive feature OSB boards from other similar materials is that the ability to hold fasteners is provided not by resin, but by the way the wood chips are laid.

Styrofoam

Expanded polystyrene is 98% composed of carbon dioxide, thanks to which it has its own thermal insulation qualities. It burns, melts from an open flame and releases compounds in the process. Mice love to settle in polystyrene foam, gnawing nests in it. In SIP panels, expanded polystyrene is closed on both sides with OSB boards, which ensures (albeit partial) fire safety of the structure. It is used in SIP panels due to its low cost and lightness.

Mineral wool

Mineral wool with a density of 100 - 120 kg/m³ can also be used in SIP panels. It does not support combustion, does not burn itself and does not spread fire. May release during heating unpleasant odors binder, but, nevertheless, much more environmentally friendly than expanded polystyrene. It is rarely used in SIP panels due to its high weight (the panel will weigh 2 times more than with PSB) and high cost. The use of mineral wool as a core increases the cost of a house made of sandwich panels by 1.5 - 2 times.

Projects of houses from sandwich panels

Having decided to build a house from sandwich panels, you first need to create a project for the house. Panel construction technology provides a large field for choice finished project and allows you to adapt other projects.

SIP panels are produced in standard sizes 2500x1250 mm and 2800x1250 mm. This determines the typical height of the first and second floors of the house. Although you can build walls of any height, but then you have to finish the panels, which is not very beautiful and reliable.

The thickness of the panels 124 mm, 174 mm, 224 mm determines the area of ​​the internal space. For internal partitions, panels with a thickness of 124 mm are used.

Without the help of a construction organization in this matter, it is still impossible to do. Making sandwich panels on your own negates all the savings and low cost of such a house, since this is not an easy and time-consuming task.

By contacting a design bureau or a construction company, you need to develop a project for your home. Then, on the basis of this project, SIP panels of the required size and parameters are manufactured. It is also possible to buy strictly standard panels and then customize them for the project, but it is laborious and time consuming. When the order for the production of panels is completed, they are delivered to the construction site by a truck and the assembly of the house begins.

Foundation for a house from SIP panels

A prefabricated sandwich panel house is a lightweight structure that does not require a heavy buried foundation. The most commonly used tape shallow foundations or slab, pile-grillage, tape-columnar.

Consider the option of a shallow strip foundation:

• We carry out the marking of the site and excavation to a depth of 50 - 60 cm with a width of 40 cm.
• We compact the soil, fill in a layer of sand 10 cm and carefully tamp, then a layer of crushed stone 10 cm and also tamp.
• Then we install a wooden formwork for the foundation to a height of up to 50 cm above the ground. We make holes in it for air in advance.
• We tie the reinforcing cage and lower it into the trench.

• We prepare a concrete solution or order a mixer and pour the foundation. Remove air bubbles with a vibrator.

Let the foundation dry completely for 28 days, then remove the formwork. We waterproof the surface of the foundation, laying roofing material in 2 - 3 layers or hydrostekloizol, coat it with bituminous mastic on top. It is better to do this shortly before the start of the construction of the walls, so that the waterproofing layer is not exposed to the open air for a long time.

Laying a strapping (crown) beam

We take a beam with a section of 250x150 mm and lay it in the middle of the foundation. We carefully measure the horizontal position of its location.

We connect the beam in the corners with the help of a cut “in half a tree” or “in a paw”. Then we fix the connection with a wooden dowel. To do this, we drill a hole in the bars with a diameter of 20 mm and a length of 100 - 150 mm. We drive in a dowel with a length slightly less than the hole. We finish it with a mallet.

We fix the beam to the foundation with the help of anchors. There are two anchors in the corners and at a distance of 1.5 - 2 m from each other. The length of the anchor should be 350 mm, diameter 10 - 12 mm. We embed the heads of the anchor bolts into the strapping beam.

Arrangement of the floor and ceilings in the house from SIP panels

A feature of construction using Canadian technology is that it is possible to build a house from sandwich panels completely, including the floor, the floors, the attic floor, and even the roof.

But our domestic construction companies nevertheless, it is recommended in such houses to equip an ordinary wooden floor on logs, laying insulation between the logs. So it will turn out more reliable and durable, such a floor is easier to repair and disassemble in case of unforeseen situations or breakdowns.

Consider the option of arranging the floor from SIP panels:

• We prepare the bars, which will act as floor lags and spike beams, which must be inserted between the panels. The length of the beam should be such that it easily fits on the foundation and into the groove in the strapping beam. The cross section of such beams depends on the thickness of the sandwich panels: 150x50 mm if the panel is 174 mm thick, 200x50 mm if the panel is 224 mm.
• We lay out the panels for the floor of the house. We cut them to the required size with a regular saw. If you need to remove the insulation, then we use a home-made thermal cutter (some companies offer it along with panels).

Important! The gap between the edge of the OSB board and the surface of the insulation inside the panel should be 20 - 25 mm. This is enough to tightly connect the panels with a beam 50 mm thick.

• We start the assembly with the corner panel, splicing them along the length in a row. We foam the groove of the panels with mounting foam and insert the beam inside. Press firmly and hold for a few seconds. We fix with galvanized self-tapping screws with a pitch of 150 mm or wood screws 3.5x40 mm.
• Then, from the side of the beam, we fasten the second panel. To do this, we also foam the groove in it. We put the panel on the beam and press it.
• Repeating all these steps, we assemble the entire floor.
• Then it is necessary to fill all the grooves remaining around the perimeter with boards 25 mm thick. The procedure is not too different: the groove must be filled with foam, then the board must be inserted, pressed and fixed with self-tapping screws.
• The resulting structure with the help of a lever mechanism or heavy equipment must be laid in place for the floor. The protruding parts of the beams / log must be fixed to the foundation with anchors using steel angles. Insert the logs themselves into the places of the cut in the strapping beam.

Important! Sometimes they do it differently. The connecting beams do not have protruding parts, they are the same dimensions as the dimensions of the future floor. After the construction of sandwich panels is assembled, into the grooves of which the beams are inserted, the panels are also connected along the perimeter with a solid strapping board 40x200 mm. Then this design is installed on the beam of the lower trim and fixed with anchors.

Construction of walls from SIP panels

The next stage in the construction of a house from sandwich panels is the laying of a guide board, it is also called "lying". The dimensions of this board are completely dependent on the thickness of the sandwich panel. Let's assume for simplicity that our sandwich panel is 224 mm thick. Then we need a board 50x200 mm.

• We lay the board on top of the strapping beam or floor (depending on the method of floor installation), align the strict horizontal and fix it with self-tapping screws 5x70 mm in increments of 350 - 400 mm. In this case, it is necessary to retreat from the outer edge of 10 - 12 mm.
• Having carefully studied the layout of the wall panels, we begin the installation from the corner.

Important! When constructing walls from sandwich panels, it is extremely important to install the first corner panels evenly. All other panels will only repeat the spatial arrangement of these two, and it will be impossible to make a mistake and put them non-vertically.

• We put two panels vertically in a corner. We pre-foam the bottom groove of the panel and put it on the bed. Align strictly horizontally and vertically. We fasten the panels to the bed with self-tapping screws 3.2x35 mm in increments of 150 mm.
• We connect the panels together. To do this, you can insert a square-section board between them, or you can fasten them together at once, we foam the grooves, press them tightly and fasten them with self-tapping screws 12x220 mm in increments of 500 mm.

• All other panels are mounted in the same way. The groove of the installed panel is filled with mounting foam, the bottom of the installed panel is also filled, the latter is put on the bed. A timber / board with a section of 50x200 mm is inserted between the installed and installed panels. The connection is tightly pressed and fixed: from below to the bed with self-tapping screws 3.2x35 mm, from the side between themselves with self-tapping screws 12x220 mm.

• After the walls are completely mounted, the upper groove of the panels is also filled with foam, then the upper strapping board / timber 150x200 mm is inserted into it. The beam is fixed to the panels with self-tapping screws 4.2x75 mm, both panels are fixed to the beam on both sides with self-tapping screws 3.5x40 mm.

Openings for windows and doors can be cut in already installed walls or in advance, which is somewhat more difficult to accurately calculate, except for those cases when sandwich panels are ordered strictly according to the project at the manufacturer's factory.

Floor beams are attached to the beam of the upper trim in a standard way. There are several such fasteners: by cutting, using corners or brackets. You can choose any.

Important! As already mentioned above, the floors of the second or attic floor can also be completely made using sandwich panels, just like the floor. But this method is not strong enough and more laborious.

Arrangement of the roof in the house from SIP panels

The roof for a house made of sandwich panels can be made as a regular rafter, where the rafters rest on the Mauerlat or on the grooves cut in the stud beams of the attic floor. Then the crate is stuffed on the rafters and the roofing material is laid. If the attic is cold, it does not make sense to insulate it. If an attic is planned, then a heater is laid between the rafters and closed from the inside vapor barrier film. From the side of the roof, a waterproofing superdiffusion membrane is stuffed onto the insulation.

But there are other ways as well. On the photo showing houses made of sandwich panels, it can be seen that the roof is completely made of sandwich panels. In this case, the installation of the roof is carried out, starting from one edge, with a gradual build-up along the ridge. First, the first rafters are installed, which are fixed with self-tapping screws to the Mauerlat. Then sandwich panels are attached to them, just like in the walls.

Then the next rafter is installed, which is inserted into the groove of the previous panels, etc. This method is more time-consuming than the installation of a conventional roof with insulation.

In general, assembling a house from sandwich panels is not very difficult task. Two or three people will cope with it in two weeks if the weather is favorable. In rainy weather, it is better not to work with panels, as the edges of fresh cuts are unprotected and susceptible to moisture. Best way to install windows standard sizes so you don't have to order individually.

Houses from sandwich panels: video - lesson

SIP panels or sandwich panels are now in great demand in the construction of structures such as low-rise buildings, cottage villages, hotel complexes, private houses and recreation centers. It is possible to build a house from sandwich panels at any temperature, and the price of this building material considered to be quite acceptable. In addition, the projects of such houses are characterized by a beautiful appearance and are environmentally friendly.

Pros and cons of projects of residential buildings from sandwich panels

Before proceeding to the direct design of a house from sandwich panels, you should understand what is advantage of such structures:

• It will take a little time to build such a house.
• Building a house from sandwich panels can be carried out at any time of the year.
• The erected structure has thin walls, as a result of which it is possible to expand the usable area inside the house.
• Excellent thermal insulation performance. Such a house warms up very quickly and keeps heat for a long time, so you do not have to think about.

• Residential buildings made of sandwich panels are not subject to shrinkage and deformation. It is possible to carry out finishing inside and outside the building immediately after it has been erected.
• Excellent level of soundproofing.
• Savings on heating.
• It is not required to erect a reinforced base.
• Houses made of this material are highly durable.

Each material has its pros and cons. SIP panels are no exception, for them the following shortcomings:

• Short service life.
• Complete tightness, resulting in optimal conditions special ventilation is required.
• Material such as SIP panels undergoes a combustion process, as a result of which a large amount of toxic substances are released.
• If used incorrectly or if there is no adequate ventilation, fungus and mold can live in the panels.

In the case of the sale of such a structure, its price will be much less than that of a house built of brick.

Building design process

There are a large number of projects of houses made of sandwich panels. Today, two-story buildings erected from SIP panels with an area of ​​​​100 m2 are in great demand.

Thanks to a convenient layout, such houses are very convenient in terms of use, as a result of which such buildings become more functional. In the basement, you can place a garage in which you can store tools.

On the second floor, it is best to place the living room, hall, kitchen, bathroom and boiler room, which would lead to the garage. Connect the first and second floors with an elegant staircase, climbing which you would get into the office. On the second floor there can be an additional bathroom and 3 bedrooms. You can enter the house from the main facade. The kitchen, located on the ground floor, should have its own exit to the terrace. Equip the attic as a study or bedroom.

How to build a private house

You can easily build a private house from sandwich panels with your own hands if you have at least a little experience in the field of construction.

Main stages of construction:

1. Building a foundation.
2. Installation of crown beam.
3. Floor arrangement.
4. Wall construction.
5. Roof installation.

Foundation construction

Prefabricated houses made of sandwich panels have the appearance of a lightweight structure, so there is no need to equip a reinforced foundation. For example, consider the arrangement of a shallow tape base:

• Mark the area for construction and excavate the soil, 50-60 mm deep.
• To compact the soil, fill in a layer of sand, 10 cm thick, then tamp it well and cover it with a layer of crushed stone of the same thickness, tamp again.
• Install wooden formwork, 500 mm high. Prepare air holes in it in advance.
• Tie the reinforcing cage and install it in the trench.
• Prepare a solution of concrete, pour the foundation. Remove air bubbles with a vibrator.
• Wait 28 days for the foundation to dry completely before removing the formwork.
• Lay 2-3 layers of roofing material, and apply bituminous mastic on top. It is better to carry out this procedure before you build walls so that waterproofing material has not been outdoors for a long time.

The installation process of the crown beam

This process involves the following procedure:

• Install a beam with a section of 250x150 mm in the middle of the base. It is extremely accurate to measure the horizontal position of its placement.
• Using a notch "in the paw", connect the timber in the corners.
• Secure the connection using a wooden dowel.

The burs can be attached to the foundation with anchors 350 mm long and 10-12 mm in diameter.

Floor and floors

When you build a prefabricated sandwich panel house, installation of the floor and ceilings is carried out according to the following plan:

• Prepare the boards that will be used as the floor lag and stud beams, and insert them between the panels. In order for the laying of the beam on the base of the house and in the groove-cutting to be easy, you need to choose its correct length. The cross section of the beams is selected depending on the thickness of the SIP panels.
• Lay out the floor panels, cut them to the desired size using a regular saw. To remove the insulation, you need to use a homemade thermal cutter. Between the edge of the plate and the surface of the insulating material, a space of 20-25 mm must be left, then it is possible to achieve a tight connection of the panels with a bar, the thickness of which is 50 mm.
• The assembly must begin with the corner panel, connecting them in a row along the length. Foam the panel groove with polyurethane foam and insert the beam inside. Fix with galvanized self-tapping screws at a distance of 150 mm.
• From the side of the beam, fasten the 2nd panel in the same way. As a result of repeating all the steps described, assemble the entire floor.
• All grooves that are around the perimeter must be filled with boards, the thickness of which is 25 mm. This procedure is practically no different from the previous one.

How to make a crate for corrugated board, you will read.

Using heavy equipment, place the resulting structure on the floor area. Those parts of the lag that protrude should be attached to the foundation with anchors. The installation of the log is carried out at the cutting site in the strapping beam.

Wall construction

When you have erected the foundation, floors and equipped it, you can proceed to the next stage, namely, the construction of walls:

• Lay a board with the required cross section (here it all depends on the thickness of the material used) on top of the floor strictly horizontally and fix it using self-tapping screws 5x70 mm for this purpose, at a distance of 350-400 mm from each other. When building walls from the presented material, it is very important that the installation of the first corner panels occurs perfectly evenly. Subsequent panels will be located similarly to these two, and here it will be impossible to make a mistake.
• Install 2 panels vertically in a corner, pre-foaming the groove of the panel at the bottom, put it on the bed. Panels must be installed strictly vertically and horizontally. Using self-tapping screws 3.2x35 mm, screw the panels to the bed at a distance of 15 cm.
• To fasten two panels to each other, you need to insert a board with a square section, foam the grooves and screw them using self-tapping screws 12x220 mm, at a distance of 50 cm.
• Installation of all other panels is carried out according to the same principle. The groove and the bottom of the installed panel must be filled with mounting foam, and the latter is put on the bed. Taking a board with a section of 50x200 mm, you need to install it between the already delivered and mounted panel. Fixing the connection occurs when using self-tapping screws 3.2x35 mm.
• At the end of the installation of the walls, the upper groove of the panels should also be filled with foam, after which the correct strapping board with a section of 150x200 mm should be inserted into it. The fastening of the beam occurs when using self-tapping screws 4.2x75 mm. Panels are fastened to the board with self-tapping screws 3.5x40 mm.
• Window and door openings are best made in already mounted walls.

If the attic is planned to be used, how living quarters then it needs to be insulated. To do this, lay the insulation and close it from the inside with a vapor barrier film.

This completes the construction of the house from metal sandwich panels.
