Do-it-yourself garden house from sandwich panels. Sandwich panel houses are a great opportunity to quickly build a cozy residential building

Currently, among the urban population there are more and more people who want to exchange their dull apartment in the center of the metropolis for a house in a quiet village. Projects of houses from sandwich panels are an ideal solution for cases where residents do not have financial means for the exterior cladding and insulation of their new home.

Many construction companies face unpleasant situations when the customer cannot pay for a certain part of the work. This raises the question of the possibility of saving on individual components of the house, which, of course, will lead to a deterioration in the performance of the building. The modern building materials market has the necessary sealing and cladding materials that will help not only save a significant part of the family budget, but also give the house first-class insulation qualities.

Sandwich panel house project with carport

Sandwich panels have a lot of advantages over other heaters. This material is structural panels consisting of several layers. Due to the simple shape of the panels, they can be installed on any surface without fear of damage to the frame of the house. Wall panels covered with classic sandwiches are highly resistant to frequent precipitation, strong winds, critical temperatures and other adverse effects of capricious weather.

Sandwich panel coating protects the main structure of the house from fungal attacks and other destructive factors, which is very convenient when operating houses made of glued laminated timber and other types of wood.

The room creates a separate microclimate with a normal level of humidity and a favorable temperature.

Sandwich panel house project

In most cases, they are used in the construction of cottage settlements, urban settlements, small hotels, private houses and recreation centers.

The main advantage of construction is the possibility of carrying out work at any time of the year, the quite acceptable cost of the main building material, as well as its full compliance with all necessary technical parameters. Houses built from sandwich panels have a pleasant appearance and high environmental safety. In addition, it is impossible not to note the ease and speed of construction, installation of the structure, as well as the possibility of building a foundation in almost any climatic conditions.

Arrangement of the roof and assembly of the house structure takes only a few working days, which allows you to start interior and exterior decoration of the building as soon as possible. After the final finishing, the house can be settled.

In this video, you can learn more about all the advantages of prefabricated houses and cottages from sandwich panels.

Production of sandwich panels

Classic sandwiches are made of glass wool or other insulating materials, which are compressed by special insulating panels. At all stages of production given material is processed with special substances that give the product high resistance to any external influences.

Sandwich panels

Sandwich panels have first-class sound and thermal insulation properties.

Technology

The basis of the technology for using sandwich panels is application of three important materials:

expanded polystyrene foam;
flat-pressed boards containing wood chips;
dry calibrated antiseptic wooden frame.

Wall sandwich panels

During the production of the material, a special coating is applied to the outer surface of the panel sheathing, which provides reliable protection against corrosion, exposure to acid environments, ultraviolet radiation and mechanical damage (for example, abrasion).

After completion of the construction of the structure, if necessary, it is possible to carry out plasterboard finishing from the inside. It is attached with guides, which allows the walls to look perfectly smooth. When finishing the outside, you can use any material: plaster, lining, siding, block house, facing brick etc.

Typical wall sandwich panels

Structure wall panels:

sheet made of galvanized steel with finishing and coating;
special synthetic glue;
layer mineral wool;
labyrinth lock connection.

Roof sandwich panels

Roofing sandwich panels are indispensable for the arrangement of roofs of houses that are built using frame-panel technology. Roofs of roofs, equipped with this type of technology, have a high level of reliability, a wonderful appearance, and excellent indicators of heat and sound insulation. The structure of the roof panels is similar to the wall view.

The main difference between roof panels and wall panels is the presence of a high rib and a special lock connection, which prevent the penetration of moisture into the room. To protect the roof panels from deformation and aggressive effects of various weather conditions, a special coating allows outer surface skins. Roof coverings

The most common sandwich panel roofing today are metal tiles, bituminous tiles and bituminous corrugated sheets. Less popular, but just as popular are roofs, in the manufacture of which cement-sand or ceramic tiles were used, as well as various alloys or non-ferrous metals. In some cases, you can find a roof created using natural materials(straw, shingles, slate).

An example of arranging the roof of a house from sandwich panels

Economy class roof types

metal tile;
Slate (asbestos fiber sheet);
Bituminous tile (Flexible tile, Katepal, Shinglas);
Cement-sand or ceramic tiles;

Premium roof types

Roofs made of alloys and non-ferrous metals (zinc-titanium, copper, roofs with aluzinc);
Cement-sand or ceramic tiles.

On this video you can see how the construction of houses from sandwich panels is going on, and what your future country cottage will consist of. You can also evaluate ready-made projects of country private houses from sandwich panels.

NIAL-SK LLC offers services for the construction of houses from sandwich panels on Russian market low-rise construction and industrial facilities.

The term "Canadian technology" is the construction of objects and houses from sandwich panels. In Russia, North American technology has appeared relatively recently, but has already conquered a certain market segment. Today, we can confidently evaluate all the positive aspects of this development. Canadian technology materials are used that comply with the following characteristics: strength, reliability, durability, unique thermal insulation and many others.

All technical parameters of these buildings are ideal for Russian conditions - low temperatures air do not require high costs for space heating due to low thermal conductivity and high thermal insulation of SIP-panels. And mobility and ease of installation guarantee a short time for the construction of the facility.

Our organization always fulfills its obligations to customers on time on the basis of a concluded contract and an approved estimate, taking into account a flexible system of discounts and optimal solutions for each object.

Sandwich panel construction - not only at home

Our company offers you to make a choice and build a turnkey house from sandwich panels, as well as garages, change houses or other outbuildings. Technical capacities of production allow to carry out construction of cottage settlements. The construction of objects is carried out both according to ready-made standard projects, and according to individual sketches or the wishes of customers.

It is a fairly widely used material in the construction of houses. Its design assumes the presence of two sheets of metal along the edges, as well as a layer of insulation between them. For the manufacture of panels of this type, galvanized stainless steel is most often used, as well as polyurethane foam, basalt fiber and a number of other materials with good thermal conductivity.

The "layers" of metal and insulation are interconnected using a special adhesive or self-tapping bolts (the specifics of fastening depend mainly on the characteristics and properties of the materials used for their manufacture).

Application area

Sandwich panels are used most often in cases where a construction company is faced with the need for the fastest and highest quality construction of houses and some other residential structures. They are ideal for commercial premises, warehouses, car washes, hangars and some other buildings based on metal structures.

Kinds

Depending on the type of insulation used, there are three types of sandwich panels:

Sandwich panels using mineral wool are the safest because the material used for their production is highly fire resistant. This minimizes the risk of fires. However, high ability cotton wool to absorb moisture often leads to the fact that the structure sags, deforms and loses its original shape over time. Subsequently, this can lead to metal peeling. The use of sandwich panels with mineral wool in construction also leads to an increase in the load on the frame of the house, as well as its foundation. The installation of such sandwich panels is quite complicated and requires the use a large number physical resources.
Expanded polystyrene used in construction is moisture resistant and environmentally friendly. Due to its light weight, it is safe for both the foundation and the building frame. Sandwich panels of this type are quite easy to install; they are quickly produced and different affordable price. However, when comparing it with mineral wool, it is necessary to note the lower fire resistance.
The third type of sandwich panels is made using polyurethane foam. Due to the low thermal conductivity, this material is ideal for freezing equipment. However, at the same time, it is not environmentally friendly, and also has the lowest fire resistance of the presented materials.

Advantages and disadvantages

Houses made of sandwich panels have the following advantages:

The light construction of sandwich panels significantly reduces the load on the supporting structures of the building.
The high speed of the construction of the building is achieved due to a fairly simple technology.
The low cost of sandwich panels allows you to significantly save on construction.
Good fire resistance indicators allow houses made of sandwich panels to have a higher fire safety.
The materials used for the production of sandwich panels guarantee a high environmental friendliness of the house.
High flexibility gives the owner of the house ample opportunities for modernization.
Good heat and sound insulation significantly increase the comfort of living in a house made of sandwich panels.
Installation work related to sandwich panels can be carried out at any time of the year convenient for you.

However, at the same time, houses made of sandwich panels have the following disadvantages:

Despite the strength of sandwich panels, they are categorically contraindicated for long and heavy loads.
If installation work were carried out in the cold season, the panel joints may freeze.
The service life of sandwich panels most often does not exceed 50 days.
If the insulation for sandwich panels was produced with the addition of basalt, this may adversely affect its thermal insulation and strength characteristics.
To protect the supporting frame, it is necessary to use materials that protect against corrosion (metal) and from rotting and fungus (wood).
The presence of expanded polystyrene and polyurethane foam in sandwich panels significantly increases the fire hazard.

Construction

The construction of houses from sandwich panels is multi-stage, and each of them has its own rules and regulations.

Stages

At the first stage of construction, the installation of the foundation is carried out. The depth, as well as its type, depend on the geographical features of the area, the location ground water, relief. The cost of a sandwich panel house foundation is about a fifth of the cost of building a house as a whole.
The installation of the house building itself takes place almost in parallel with the construction of the foundation. At the beginning of construction, beams pre-treated with an antiseptic are attached to the foundation. Most often used for fastening. The sandwich panels themselves are interconnected using wooden boards, the thickness of which is usually about 4 cm. Subsequently, it is this design that will play the role of the frame of the entire building. To strengthen the structure, as well as to process the joints, a special mounting foam is applied to the joints of the sandwich panels. Particular attention should also be paid to "cold bridges", namely, places where condensate can form due to increased heat loss. Every two panels require about one bottle of foam. To improve the waterproofing of the panels, it is also possible to cover their undersides. The installation of other floors of the house is carried out at a similar level.
Roofing with sandwich panels is carried out traditional methods considering the load on constituent elements. After construction works are completed, be sure to consider covering the roof with waterproofing material.
Mounting engineering systems can be carried out at almost any stage of construction, however, it is best to carry out similar works after the whole box is assembled at home. It is desirable that all communication systems be as accessible as possible, and the external surfaces in contact with the pipes must be covered with insulating material.
Since the sandwich panels do not precipitate, the installation of doors and windows is already permissible. All other finishing works can be carried out autonomously from each other.

Peculiarities

It is best to start the installation of panels from the corner of the house; moreover, the maximum deviation can be a value from 1 to 1.5 mm.
The second panel is attached to the first strictly at a right angle using self-tapping screws.
Corner panels are mounted with the participation of a maximum of two assemblers.
Installation of wall panels with doorways, as well as solid wall panels, is carried out using the same technology.
The thickness of the sandwich panels used for the internal partitions of the living space is approximately 120 mm.

Sample projects

The design of buildings from sandwich panels is carried out depending on the characteristics of the material used for the construction of the frame, the distribution of loads on the load-bearing elements of the building, as well as environmental conditions.

Construction cost

The cost of building a house of this type depends mainly on the amount of work performed, the area of \u200b\u200bthe premises, as well as the cost of sandwich panels. However, it is worth noting that the construction of houses from sandwich panels is much lower than similar houses made of bricks or any other materials.

The rapid development of building technologies leads to the regular appearance of new materials. Sandwich panels can be counted among them: having appeared on the construction market not so long ago, they quickly gained great popularity.

Sandwich panels have a complex structure that includes several layers. Inside there is an insulating base, for the manufacture of which a foamed or extruded polymer or mineral wool is used. The extrusion filling is very durable, and has higher insulating characteristics. The heat-insulating core is closed on both sides with protective PVC sheets. On the front side, a better glossy or matte plastic is used, on the inside - a durable rough sheet, on which an adhesive is smeared. In addition to PVC, OSB board or steel sheet can be used to make the outer walls of the sandwich.

Sandwich panel device

A simpler version of the sandwich consists of two layers (there is no back protection). External walls and internal thermal insulation are securely connected with a special hot-melt adhesive: Hot-Melt technology is used for its manufacture. As part of a two- or three-layer structure, there are no toxins harmful to the body: this opens up wide opportunities for the use of sandwich panels in the social and housing sectors.

Appearance of sandwich panels

Multilayer panels can be safely attributed to universal materials that are used both in decoration and in the construction of buildings.

Sandwich panels are excellent as building material, from which various low-rise objects are constructed:

Industrial. The material is used for the construction of warehouses, hangars, production areas.
Public and household. We are talking about office space, retail outlets, change houses.
Filling, repair, washing stations for vehicles.
Sports. Gyms, indoor skating rinks, etc.
Agricultural. Farms for breeding poultry, animals, various greenhouses.
Refrigeration and freezing warehouses.
Medical and other sanitary facilities.

Sandwich panels are used in various kinds facilities

In addition, panels of this type are often used in cases where reconstruction or thermal insulation of dilapidated houses with insufficiently strong ceilings is carried out.

The main classification of sandwich panels - according to the type of internal filler:

In addition, there is a classification of sandwich panels according to the material of the outer sheets: they can be metal (galvanized), PVC or oriented strand boards (the so-called "SIP panels").

The undoubted advantages of sandwich panels include the following characteristics:

The material also has weak points:

Thanks to the sandwich panels, the emergence of the technology of rapid construction of buildings, which is very popular today, has become possible. Thus, it is possible to equip an object in a short time, regardless of the weather. Prefabricated buildings are built, as a rule, within 2-3 weeks (including the time for drafting the project). The complexity of the structure being erected in some way affects the duration of the construction.

Installation of sandwich panels

However, in any case, this happens much faster than when using bricks, foam blocks and other traditional materials. Such fast construction time is explained by the small total mass of the object. In this case, there is no need for a monolithic powerful foundation, the laying of which usually takes a lot of time and resources: and it is the foundation device that “eats up” a significant part of the time and money. The construction of prefabricated buildings is carried out by a small group of installers (3-4 people) without the involvement of specialized equipment. In this case, it is quite possible to do with manual devices.

The order of construction work:

Design. To save time, one often goes through the use of a suitable standard project, which can be customized.
For sufficiently large structures, it is recommended to use reinforced concrete panels as a foundation. However, if the building is small and light enough, consider a brick or concrete stone foundation with an additional layer of waterproofing.
To install individual elements, you will need a reliable frame, for the construction of which lumber or metallic profile. The installation procedure is carried out with a screwdriver and a special lock. With the proper qualification of the performers, the build-up of the structure occurs very quickly.

Sandwich and SIP panels are also used in the construction of the so-called. "inertialess" (frame) buildings. This technology is characterized by the use of materials with good insulating properties with low heat capacity. Such objects are distinguished by a very rapid increase in the air temperature in the premises, during which the camps remain cool. They try to make them as tight as possible, which makes it possible to spend minimal money on heating.

Frame building from sandwich panels

Inertialess structures made of SIP panels operate on the principle of a thermos: their walls cool down quickly, and the air remains warm for a long time even after turning off the heating. This technology is widely used in the construction of modern dachas and country cottages with temporary residence. Given the tightness requirements, such houses will require a rather complex ventilation system, the air ducts of which are constructed from ceramic pipes or brick ducts.

From the point of view of economy, frame structures are the cheapest (especially if SIP panels are used). Even taking into account the mandatory use of expensive forced-air ventilation, the cost of construction frame house inferior to brick counterparts by about 1/3. It should be borne in mind that any prefabricated building in terms of durability is an order of magnitude inferior to brick or foam block structures. Strictly speaking, similar building designed for one generation.

In order to maintain the overall style prefabricated buildings from sandwich panels, began to produce special products for roofing. In such cases, mineral wool acts as an inner layer, and the panels themselves have higher load-bearing characteristics. Using such products, designers have ample opportunities for a natural complementary overall design, when not only the appearance is maintained, but also the method of building the object. For the manufacture of roofing sandwich panels, only fire-resistant materials are used: basalt insulation, profiled steel sheathing, non-hot glue.

Sandwich panels for roofs and walls

Considering sandwich panels as a material for the construction of a building, first of all, it is necessary to determine the purpose of the object. As the main material, this material is most often used in the construction of industrial or social facilities. We are talking about various pavilions, hangars, gas stations, warehouses, etc. At the same time, the so-called. "industrial" style.

These materials are also used in the residential sector ( frame construction), which can significantly reduce the construction time. However, buildings of this type are not very durable, so if you want to get a cottage for centuries, it is better to use traditional brick or blocks. Sandwich panels in private construction are more appropriate to use for the construction of minor buildings (except for baths, due to the low heat capacity of the walls).

cost of sandwich panels

Sandwich panels are fairly inexpensive materials.

The final price depends on the following factors:

Manufacturer. Domestic samples are much cheaper than Western ones.
type of heater. The most expensive are products based on basalt wool.
Facings.(Type of material, number of layers).

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, cheapness and minimum costs for operation. 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, they 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

AT recent times advertising of houses from sandwich panels does not stop 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 start interior and exterior decoration 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 polystyrene foam, 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, it is necessary to arrange a forced supply and exhaust ventilation. 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 kind 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 durable sheet material is used: OSB (oriented strand board), magnesite board, fiberboard (hardboard), wooden planks. 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 with a thickness of 12 mm 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 glued 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 help construction organization still unavoidable in this matter. 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. truck and start assembling the house.

Foundation for a house from SIP panels

Prefabricated house from sandwich panels - lightweight construction, which 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 still recommend equipping such houses with 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 bottom strapping 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 when sandwich panels are ordered strictly according to the design at the factory.

Floor beams are attached to the beam of the upper trim in the 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 spiked beams attic floor. Then the crate is stuffed onto the rafters and laid roofing material. 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 with a 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.
