Cottage from metal sandwich panels. An affordable turnkey price for a country house made of sandwich panels, reviews and photos of which can be found on the Internet, make these buildings in demand

LLC "NIAL-SK" offers services for the construction of houses from sandwich panels in the Russian market of 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. For construction using Canadian technology materials are used that meet the following characteristics: strength, reliability, durability, unique thermal insulation and many others.

All technical parameters of these buildings are ideal for Russian conditions - low air temperatures 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.

Only modern materials

We use modern construction technologies from sandwich panels, adhering to all applicable standards and regulations. By choosing us as a contractor, you will save time, money and get a comfortable and warm home.

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.

A good house takes a long time to build. This axiom served as a guide for many years for those who wanted to acquire their own housing. It is difficult for people who value quality to come to terms with the idea that a warm and reliable house that can easily withstand Russian frosts can be built in 3 months. The technology that originated in the United States came to Russia from Canada, a country that is also famous for its remoteness from resorts and harsh climate.

Despite the initial distrust, progressive technology has established itself in the domestic construction industry, conquering developers with the speed of construction and quality that does not suffer from the speed of construction work. Turnkey sandwich panel houses are increasingly turning into an option worth considering and choosing.

A house built using frame technology is beneficial in all aspects

Sandwich panels: appearance and purpose

The material got its name due to its similarity to a three-layer sandwich, in which the role of bread is played by two facing surfaces, and the role of the filling is a layer of thermal insulation. The most famous type of material is considered to be SIP-panel (structurally insulated panel). Panels have found application:

In housing construction. They serve as the basis for prefabricated frame structures.

in commercial construction. For the construction of industrial and large public buildings, trade and warehouse visits, halls and car washes, panels with metal cladding are chosen.

This frameless building material, which meets all production standards, serves as the basis for houses known under the names: modular, panel, frame, frame-panel. By functionality, the panels are divided into wall and roofing.

Installation of roof sandwich panels

Wall

The panels are used for the construction of walls, interfloor ceilings and load-bearing partitions, as well as a finishing material. According to the type of external profile, they are smooth and profiled. The latter are divided into simple and decorative (with the effect of siding or a log structure).

The material is applicable for insulation and reconstruction of old buildings. The key properties that determine the quality of the panels are strength and thermal parameters, as well as fire resistance limits.

Roofing

The material is widely used in the installation of not only pitched roofs, but also other types of roof structures with an angle of more than 5 °. Roofing sandwich panels have a metal cladding and a wave-like profile, which increase the rigidity of the products. Profiling can be double-sided or front. Additional requirements for roofing panels are durability and high load-bearing capacity.

Facade cladding with sandwich panels

Decorative (finishing)

Sandwich panels for houses are widely used for facing the facade parts of houses, finishing window and door openings (shaped elements). They have an excellent appearance, reliably isolate the building from moisture (which is especially important when installing ventilated facades) and are resistant to UV radiation. Decorative panels are made from:

Wood. Are applied to external and internal finishing works.

Plastic. Practical budget option.

Metal. They can be used for finishing loggias and balconies, during restoration and repair.

Material and design

The scope of use of the panels is determined by the type and characteristics of the materials of the shell and filler. The choice of raw materials determines the quality of sandwich panels even before the start of the production cycle.

Construction of galvanized panel

outer layer

For the outer layers, rigid sheet material with a protective coating is used; most often it is:

Galvanized steel(or metal alloy). The surface is reliably protected from corrosion. A house made of metal sandwich panels is durable (the thicker the zinc layer, the more durable the structure).

Drywall. Eco-friendly (two sheets of building cardboard separated by a layer of gypsum); popular way of decorating residential premises.

Plastic. Various types of material serve as reliable protection against temperature extremes, mechanical stress and moisture.

PVC. A type of plastic; due to its rigidity, it is widely used for the production of window slopes.

OSB(oriented strand board). It serves as the basis for SIP panels. The manufacturing process of the material consists in gluing wood chips under high pressure.

insulation

A common material for insulation is:

Basalt fiber(mineral wool). The most popular option with unsurpassed heat and sound insulation. Cotton wool is environmentally friendly, non-flammable and practical: it is often used in fireproof partitions.

In Finland, 40% of houses are built from SIP panels

Fiberglass. According to the characteristics, it resembles mineral wool, surpasses the ability to sound absorption.

polyurethane foam(PPU, PUR) and its modifications. Lightweight and durable material with a honeycomb structure. It is harmless to health, absolutely non-flammable and reliably protects against moisture.

Styrofoam(Styrofoam). Panels with this material are used in the construction of non-residential (warehouses, workshops, swimming pools) and residential buildings (Canadian technology). The material does not absorb moisture, is combustible, emits toxic substances in a flame, therefore it is not recommended for buildings with high fire safety requirements.

On our website you can get acquainted with the most popular projects of houses on panel-frame technology from construction companies presented at the exhibition of houses "Low-Rise Country".

Compound

The quality of houses built using the sandwich panel technology directly depends on the reliability of the connection of the elements. Joints affect the strength, appearance and thermal efficiency of panel walls. In the arrangement of the elements, a connecting lock of the popular “thorn-groove” design (tongue-and-groove connection) is used.

Classic tongue-and-groove connection

Bends (thorns and grooves) are formed when profiling external surfaces. Thanks to the locking connection, the panels fit perfectly with each other, ensuring quick installation. Manufacturers produce products with high-precision double and triple locks (the number depends on the thickness of the element). If the docking locks are of poor quality and do not fit well together, the seams will be leaky (they will lose heat).

Advantages and disadvantages of sandwich panel houses

The material began to be used in mass construction more than half a century ago. The accumulated experience allows us to draw a conclusion about the qualities of the technology. The advantages of sandwich panels include:

economy(compared to wood and brick). The cost of a turnkey house is 2-3 times less than a brick one.

Construction time. Works are 3-4 times faster than traditional methods.

All season. Installation is carried out all year round.

Ease of erection and processing. The panels are easily machined with standard tools for wood and metal.

Life time. It is 60-70 years old, the building becomes obsolete morally rather than physically.

Panel house device

Strength. Houses made of sandwich panels are not afraid of hurricane winds and earthquakes. The design can withstand a load of up to 10 t/m 2 vertically, transverse - 2 t/m 2 .

Thermal efficiency. The thermal insulation properties of a wall made of SIP panels are equal to those of a brick wall 2 m thick. With the same thickness, a panel house is 5 times warmer.

Moisture resistance and tightness of the structure.

Resistant to temperature extremes and ultraviolet.

Environmental Safety.

Disadvantages of sandwich panel houses:

Construction features. The house is assembled as a children's designer, each element requires an exact fit (otherwise the thermal efficiency will suffer).

Insufficient soundproofing. Eliminated by interior and exterior trim.

Frame features. The metal supporting frame must be additionally protected from corrosion, wooden - from decay.

A house made of sandwich panels needs a well-thought-out ventilation system

On our website you can find contacts of construction companies that offer the service of building houses using panel technology. You can directly communicate with representatives by visiting the exhibition of houses "Low-Rise Country".

Insulation features. Mineral wool absorbs moisture and can be deformed, polystyrene foam is flammable.

Instability to mechanical damage.

Low level of ventilation. Eliminated by installing a ventilation system.

Unprofessional installation. It is the cause of heat loss during the operation of the house (in winter, freezing of the joints is possible).

The project of houses from a turnkey sandwich panel

Every year more and more people decide to build a house from sandwich panels, taking into account the benefits not only during construction, but also during operation. Construction companies offer turnkey sandwich panel homes with designs and prices to suit a wide range of tastes and budgets. When concluding a contract, the company prepares a house project taking into account the wishes of the client and performs a full range of work. Construction goes through several stages.

Ready-made standard project with calculated cost and price

Project selection

At the customer's disposal are extensive catalogs with projects of various formats. Within any budget, you can choose a house based on the area, architectural style and additional options (type of finish, type of roof). Panel technology makes it possible to implement any architectural ideas, design ideas and interior solutions.

For the selected project, a preliminary cost calculation is made. A house made of sandwich panels is a great way to save on:

Time. The implementation of an object from sip panels will require up to 3 months.

Foundation and excavation. A massive (and expensive) foundation is not needed.

Rental of heavy construction equipment. She is not needed.

building materials.

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 a structural panel 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 using 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, this material is treated 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 of using sandwich panels is the use 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, 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, any material can be used: plaster, lining, siding, block house, facing brick, etc.

Typical wall sandwich panels

Wall panel structure:

sheet made of galvanized steel with finishing and coating;
special synthetic glue;
a layer of 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 roofing panels and wall panels is the presence of a high rib and a special locking connection, due to which moisture is prevented from entering the room. To protect the roof panels from deformation and aggressive effects of various weather conditions, a special coating of the outer surface of the skin allows. 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.

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 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 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 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, therefore, 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 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 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 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. A distinctive feature of OSB boards from other similar materials is that the ability to hold fasteners is provided not by resin, but by the way the 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. During heating, it can release unpleasant binder odors, but is nevertheless much more environmentally friendly than Styrofoam. 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. The panel construction technology gives a large field for choosing a 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) timber

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 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 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

A roof for a house made of sandwich panels can be made as a regular rafter, where the rafters rest on a mauerlat or on 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 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 a 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. It is most convenient to mount windows in standard sizes, so that later you do not have to order individually.
