Frame construction is very popular in the world, regardless of climatic conditions. The technology has become widespread, in particular, due to the fact that, having sandwich panels, in just a summer you can build warm housing. Particularly popular frame houses in countries such as the US and Japan. The technology has stood the test of time and has been used on the Scandinavian Peninsula for five centuries.
Sandwich panels conquer the construction market
The word " sandwich" on English language they call a sandwich from several layers, where bread is on top and bottom. In construction, this is a material of a special design, which is used to obtain various structural elements. The term SIP panels is also found in the literature - from the English abbreviation SIP (Structural insulated panel). The basis, or frame, is a heater, which is covered on both sides with sheets of hard material.
Sandwich panels have the following advantages over their competitors:
Less thermal energy is required to heat a building made of sandwich panels
But the material also has disadvantages:
Houses made of SIP panels are always low-rise
The scope of SIP is quite wide. It is used in combination with other materials - for example, for superstructures on existing buildings, as well as for the construction of garages, warehouses, shopping and office centers, etc.
The outer layer of SIP panels is represented by the following materials:
Thickness of one plate - 9–12 mm.
Used as a heater:

The more severe the climate, the lower the material should be.
Attention! When choosing a building material, you need to pay attention to quality - it should not be toxic or combustible. So, in developed countries (Japan, the EU states, the USA), boards with a formaldehyde emission level of at least the first class are used.
Several types of sandwich panels are in demand in construction:
Sandwich panels: advantages and disadvantages
There are other types of SIP panels, but they lose the listed products in terms of technical characteristics. For example, for internal partitions produce drywall with insulation. Those made of steel or fiberboard are used mainly for the construction of workshops and commercial buildings.
LSU panel made of glass magnesite
Attention! According to experts, panels with basalt additives retain heat worse than homogeneous materials.
In addition to modern materials, reeds and sawdust act as fillers. Although they are environmentally friendly, performance characteristics lose to synthetic counterparts.
The most popular in the construction of houses are SIP panels with an outer layer of OSB-3 12 cm thick. They are intended for load-bearing structures and are resistant to operation in conditions of high humidity.
Table 2. Basic dimensions of sandwich panels
Sandwich panels
The building material has become so popular that it is now produced not only for walls and ceilings, but also for other structural elements of the building.
SIP panels began to be used for the construction of the roof. The material has gained popularity in this area because it is ready roofing cake. If you use this design, then even additional insulation is not required. Under such a roof, you can arrange a fairly warm attic.
The framework of roofing sandwich panels is formed by sheet steel. Sheets are galvanized and coated polymeric materials, which not only give aesthetic appearance, but also protect the metal from moisture and other adverse conditions that cause corrosion. Both polystyrene foam and mineral wool are used as insulation. The roof of SIP panels withstands a snow cap, strong wind.
Separate elements of the roof are fastened together with locks ROOF-LOCK. They provide a tight connection, and do not allow leaks at the joints.
Roof sandwich panel
SIP panels for roofs are gaining popularity for the following reasons:
Table 3. Characteristics and dimensions
Important! The slope of the roof where it is planned to build such a roof should be at least 5–7 °.
The use of sandwich panels
SIP panels are increasingly used for mounting window slopes. They have this structure:
F-profile is fixed to the inner edge window slope- it closes the end of the structure. For this reason, there is no need to re-glue the wallpaper after installation. Under this profile lies a rail, which is adjacent to U-shaped profile. The structure rests on it.
In this case plastic window maximum protection from street noise and drafts. When using this finish, double-glazed windows can last 20-30 years without major repairs.
Builders note the following advantages of the material:
It is easier to work with this material, because it does not crumble and does not form a lot of construction debris. The front layer of the panel is usually covered with a material that can be washed, but without abrasive cleaners.
SIP panel for slope
But the use of this material on slopes has a number of disadvantages. So, if the side is sunny, and the coating is of poor quality, the possibility of deformation of the upper coating is not excluded. White plastic exposed sunlight turns yellow over time, which worsens the appearance of the window.
The installation of the structure is carried out in the following sequence:
Step 1. Carry out measurements of the window along the contour.
Step 2 Cut out pieces of the desired size from the sandwich panels.
Step 3 On the edge window frame attach the U-shaped profile.
Step 4 Mount the sandwich panel.
Step 5 Pour the foam into the gap between the wall and the panel.
Polyurethane sealant
Step 6 An F-shaped profile is installed on the edges of the window.
When buying a new SIP panel, the seller should ask for a certificate of conformity. If he does not have this, it is better to look for a suitable product elsewhere.
Before starting the installation, prepare a layout scheme for the selected type of material. Particular attention is paid to the location of the castles.
Slope from sandwich panels
The panels are inspected in order to detect damage and corrosion in time. If there are such places, the material is processed or replaced with another panel. Sheets on which chips peel off, friability is noticed, they are not suitable for work. Carefully work with butt elements so that later there is no depressurization of the joints.
Since the panels are produced in the same size, they will have to be cut. For this, only cold methods are used: high temperatures can damage insulating material or filler, and the service life of the structure is reduced. Internal and outer panel cut not at the same time, but one by one.
Depending on the material of manufacture, the following tools are used:
To make the incision even, the panel is fixed, a clear marking of the sheet is made. The front layer is always cut first.
Attention! A grinder and other tools with a high cutting speed are not recommended. They can cause ignition of the insulation and damage to the integrity of the protective coating.
The construction of a house from sandwich panels can often be carried out by the future tenants themselves, if they have at least basic skills in construction.
The process consists of the following steps:
SIP flooring
Elements of a frame house
Attention! Panels are installed from the corner of the frame. Since the first sheet is the guide for all the others, it is carefully placed under the level.
Since sandwich panels have a smooth, flat surface, then finishing the house is cheaper and takes less time. So, inside it is enough to paste over the walls with wallpaper.
Another building that can be built from sandwich panels is a garage.
Approximate drawing of a garage
For the construction of the premises is also enough screw foundation. But in this option it is impossible to build a viewing hole. If it is necessary, then the foundation should be tape.
Stages of building a garage:
Installation of flashing and reflux
Hangars and warehouses are built in a similar way.
For the construction of such premises, used SIP panels are also used, if their performance characteristics are preserved.
Since the material is very popular, there were craftsmen who learned how to make it with “handicraft methods” at home. On the one hand, the design is quite simple. On the other hand, there are many subtleties that beginners do not know about.
To make a panel, you will need:
There are two types of glue - one-component and two-component. One-component adhesive mixtures harden on contact with air. Two-component analogs consist of a polyol component and an isocyanate activator, and harden when these substances enter into chemical reaction together.
Attention! For home production, it is recommended to use one-component adhesives. Experts say that two-component adhesives effective only in fully automated production.
The glue has the following requirements:
The technological process looks like this:
Thermal insulation materials
Polyurethane adhesive is applied very quickly, because it dries quickly, after which it cannot be dissolved by any products. It softens only under the influence of a temperature of 300-500 ° C, but at home it is impossible to heat the workpiece to such an extent. To ensure the desired speed of work, you will need an assistant.
Attention! The curing time of the adhesive is extended if the panels are assembled in a dry and cool environment.
As mentioned, at the last stage, a home-made SIP is sent under pressure. The pressure over the entire surface should be about 300 g/m2. To do this, use a press - as a rule, a manual protracted, folding prefabricated panels one to another. If there is no such mechanism, they resort to using a vacuum pump:
The lock between the panels is made with the help of bars. To do this, on the one hand, a bar is laid along the length of the panel, on the other hand, a heater is cut to a depth corresponding to the entry of the bar.
Castle in panels
SIP panels- comfortable, modern construction material. With proper handling, it can be used to build energy-efficient and durable housing, and for a reasonable price.
A sandwich panel is a building material, the outer sides of which are made of a solid material, most often metal, and the inner side is made of insulation. They got their name due to the fact that the layers resemble a sandwich (eng. sandwich ["sænwɪʤ]) - the same materials from the outside and one more from the inside. For the first time, sandwich panels were used in 1930 in America during the construction of a residential building. Later, mass panel production. Russian Federation this building material began to be manufactured in 1974, and it quickly occupied its niche in the construction market.
Sandwich panels are often used in construction
Basically, sandwich panels are used for the construction of low-rise buildings for commercial, industrial or other purposes. Due to the "official" appearance, it is rarely used in the construction of residential buildings. Most often this finishing material designed for walls. Installation is carried out by fastening to a metal frame with self-tapping screws.
One of the areas of application of sandwich panels is the construction of industrial buildings. Source 2gis.ru
There are several types of panels.
Sandwich panels for exterior walls. They are made of metal sheets and insulation. They are mainly used for the construction of partitions, cladding of the walls of the building, for the purpose of insulation.
Roof panels. Used to cover roofs. Long term in use. They are made of fireproof materials, retain heat for a long time and isolate loud street sounds. Fastening is carried out using a unique technology that protects against deformation in warm time of the year.
Three-layer panels. Convenient to use. Installation of such plates occurs quickly, without any difficulties. There is no need to strengthen the supporting structures of the building. Manufactured from galvanized steel, polymer coating is possible. Currently this species sandwich panels are the most commonly used. This is the most modern building material. Moreover, the use of three-layer panels significantly reduces financial costs.
Corner sandwich panels. Used to create a complete image of the building. They can be semi-circular or angular. Produced from heat-resistant fireproof material.
Corner panels reduce labor costs in the construction and decoration of buildings Source kingspan.com
The panels are varied in color, which is defined by international color standards. The color must be chosen according to the climatic conditions. It is necessary to take into account the ability of light reflection and light absorption of the material. The service life of the building directly depends on this.

First of all, external wall panels are usually distinguished by internal composition insulation:
polyurethane foam. The material is practically not subject to corrosion and deformation. Resistant to thermal and mechanical influences. It is a pure ecological product. Durable enough. The cost of such panels is quite high. In this case, the material is not safe in case of fire.
Styrofoam. It has high heat and sound insulation. Not exposed to thermal influences. Eco-friendly and lightweight material. Retains its shape with prolonged contact with water. The advantage is the ability to install panels in the cold season. The main disadvantage of the filler was such characteristics as fire hazard, color change when exposed to sun rays, changes shape at temperatures above 1000⁰С, causes various allergic reactions.
Polyisocyanurate foam filler. Leading material among sandwich panels. Environmentally friendly, not subject to corrosion and deformation. Possesses the minimum thermal conductivity, elasticity. Durable, fire resistant and durable. Of the shortcomings of the building material, one can only distinguish its high cost.
Mineral wool filling. The advantages of insulation are incombustibility, good sound insulation. The material is environmentally friendly. It is not subjected to thermal deformation. In contact with metal, the possibility of corrosion is reduced to zero. It is easy to use and install. Panels filled with mineral wool also have a number of negative characteristics. First of all, it's harmful. When installing such sandwich panels, you must use a respirator. Over time, the material loses its heat-insulating properties. Work with panels is possible only in good weather, as mineral wool is not a moisture-resistant material. In contact with water, the panel may delamination. Sufficiently large weight requires additional strengthening of the supporting structures.
Mineral wool eco-friendly material, but eventually loses its properties Source s-paneli.ru
fiberglass insulation. The filler is similar in composition to mineral wool, but differs significantly in properties. Virtues this material are incombustibility, sufficiently high heat and sound insulation. The product is light, elastic, durable and environmentally friendly. Of the minuses, one can single out the high absorbency of liquids, the inability to use when high temperatures, deformation with a sharp change in temperature. May cause severe allergic reactions if inhaled.
Combined fillers. The composition of the filler includes a mixture of various building materials. Basically, it is mineral wool and expanded polystyrene.

Just like the internal filler of sandwich panels, their outer layers are made of various materials.
Paper. The addition to the paper is aluminum foil or polyethylene. You can find panels in which paper is impregnated with bitumen. Panels with such sheathing have a relatively low price and are economical to use.
Metal. Mostly thin stainless or galvanized steel is used. The metal is covered with aluminum foil, cloth or paper. It serves as a protective function upper layers panels.
PVC. Between the PVC sheets there is a layer of insulation. Such panels are used for the construction of partitions, finishing door and window openings.
Drywall, fiberboard, plywood. The product is sewn on both sides. different material. Used in the construction of office partitions. Convenient if necessary to hide the wiring.

Sandwich panels also differ in the type of polymer coating. Let's take a look at some of the main types.
Pural (pural). The material is resistant to sudden temperature changes, does not react when exposed to ultraviolet rays. It is mainly used for exterior cladding of buildings.
PE (polyester).
Polydifluorionad. The coating is resistant to aggressive chemical compositions, air temperature changes and external mechanical influences.
Plastisol. Panels with such a coating are used not only for the exterior of buildings, but also for the interior.
Panels coated with plastisol can be used both indoors and outdoors. Source usider.it
The width of the sandwich wall panels can be different. It depends on the material from which the product is made. Width varies from 100 to 103 cm. Thickness from 5 to 25 cm. Length finished product can reach 14 meters.
In detail about wall panels in the video:
The cost of the product depends on the dimensions of the wall sandwich panels: width, thickness. The choice of color also affects the cost. Prices may vary from store to store. Depending on the characteristics of the panels, prices range from 750 to 1780 rubles per m 2 *.

Although sandwich panels are rarely used for building and insulating houses, they remain an effective solution for outbuildings. In any case, professionals should be involved in the installation, because the use of any building material has its own pitfalls, which become known only through experience.
What is a sandwich panel? This term refers to a multilayer building material that is used for the construction frameless structures. During construction, the elements of the panels are interconnected by interlocking, forming a solid monolithic surface.
The first sandwich panels appeared on the construction market in 1930 year. The inventor of the design is engineer Lloyd. First used for assembly, panels immediately began to gain worldwide popularity, allowing buildings to be quickly erected. for various purposes. Russian manufacturers mastered the technology in the 90s last century.
Standard sandwich panels consist of several layers: an outer cladding and an insulating layer between them. The main components are joined together by hot pressing, or bonded with an adhesive based on polyurethane.
External cladding
Two-component adhesive layer No. 1
Two-component adhesive layer No. 2
Trapezoidal mineral wool slats
Internal lining
Protective film

Structural mineral wool lamellas
Due to the composite structure, sandwich panels have a mass undeniable merits. In particular, the pressed material has a minimum weight, which significantly reduces the load on the foundation. Enjoy sandwiches and high level thermal insulation, while the insulation layer is reliably protected by the outer lining, so the panels do not lose their properties over time.
Sandwich panels are divided according to several criteria, which determines their characteristics and application features.
By purpose, the material is divided into three groups:
Usually these are durable products designed for vertical installation. The outer cladding is made of durable polymer-coated material, color palette implies a wide range of shades. A lock system is used to connect wall elements to each other. Z-LOCK.
Such a connection ensures hermetic joining of the panels, which eliminates the formation of cold bridges, reliably protects the insulation from any external influences. It should be noted that for additional protection of butt joints, additional elements, sealant, construction tape and mounting foam are used.
In its structure and composition, the material resembles wall counterparts, however, there are some differences. For example, a lock connection belongs to the class F-LOCK which prevents moisture from entering the roof. For these purposes, a pronounced profile of the outer lining is also provided.
To protect panels from aggressive impact environment and direct exposure to ultraviolet rays, anti-corrosion coating is used. It should be noted that the panels of this category are a complete element of the roof, so they do not need additional protection of the joints.
It should be noted that according to GOST standards, some deviations in the dimensional grid are allowed, which does not classify the panels as defective. It is important to understand that the given sizes are relevant only for domestic manufacturers. In Europe, other standards apply, so sandwich panels manufactured abroad may differ from Russian standards.
As the name implies, such panels have a rather limited scope. They are used to protect the corners of buildings from moisture, improve the appearance. The panels are mounted on the corner slopes of wall structures, which provides reliable thermal insulation.
The picture above shows the façade cladding options for the so-called piece-by-piece sandwich panels.
If we talk about solid sheets, then the following materials are used here:
Galvanized or stainless steel with polymer coating.
Combined materials, where one metal sheet is replaced with drywall or DSP (cement particle board). Such options are usually used for arranging internal partitions.
Both layers are made of PVC.
The outer layers are made of special paper, aluminum foil or polyester. Such products are usually used for additional thermal insulation of floors or foundations.
Typically, manufacturers use the following materials:
mineral wool. This is a fibrous composition obtained from silicate magma and metallurgical slag. The material is completely incombustible, but very sensitive to damp environments. When installing such panels, it is mandatory to use personal protective equipment, Special attention is given to the tightness of the joints. In addition, sandwich panels with mineral wool have a rather large structural mass.
glass wool. According to its properties, the material is almost identical to mineral wool. However, due to the large size fibers, such panels have greater elasticity, respectively, are more resistant to dynamic loads.
polyurethane foam. This material has absolute environmental safety, resistant to any external influences, has excellent thermal insulation properties and moisture resistance. The only drawback of such a filler is flammability.
Styrofoam. Sandwich panels with such heat-insulating layer often used in the construction of commercial establishments, arrangement cold rooms. The material has a porous structure, which provides reliable insulation interior spaces. However, expanded polystyrene has a relatively low strength, which negatively affects its durability.

Knowing these features, it will not be difficult to choose a sandwich panel in accordance with individual requests.
Structural mass of sandwich panels directly depends on the type and thickness of the heat-insulating layer. In addition, the density of the insulation also plays a key role. For example, for mineral wool, this indicator is 110 kg/m2, at polystyrene - 25 kg/m2. Accordingly, subject to standard sizes, the weight of wall sandwich panels with mineral wool can vary within 16-39 kg. Similar products, where foam is used as a heater, will weigh 12-17 kg.

The company constantly tightens quality control of production, modernizes technological processes and uses European equipment. At the same time, the sandwich panels of this manufacturer are distinguished by affordable prices. Let out production completely conforms to the Russian and international quality standards.
It should be noted that these are not the only manufacturers of sandwich panels in Russia, however, here are the most competitive companies whose products deserve the highest ratings from consumers.
Many are tormented by a misunderstanding of what is a sandwich panel? An interesting question, but a bit of history. Quite recently, everyone who decided to build a house or a commercial premises sighed heavily. And there was a reason for this, since there was a lot of work to be done. In addition, it was necessary to select many types of different building materials. But nothing stands still, products appeared on the market that quickly gained popularity. They made it possible to build any objects quickly enough, and in structure they resembled a sandwich (sandwich). That is, several types of materials are combined together. Because of their structure, they got the name - sandwich panels.
As already noted, this type of material has a multilayer structure. Therefore, everything that more or less resembles a sandwich is mistakenly referred to as a sandwich panel. Which causes some confusion. More specifically, to be determined, the following should be said about them:
Multilayer composition of sandwich panel On a note! Often the filler can consist of several elements, each of which has its own purpose. And together they give a better result.
Basically, even the most modern material has its positive and negative sides. The first include the following:
The use of sandwich panels allows you to refuse additional expenses for finishing materials Should know! Sandwich panels can also act as an additional finishing material when you need to quickly insulate the building. They simply need to sheathe a brick or concrete wall.
There are disadvantages, they are:
The following types of material are distinguished - wall and roofing. The former are the most common, they are also most often used in construction.
Composite sandwich panels have another name - facade panels. From their second designation, it becomes clear that they are used for exterior decoration of building objects. The material has the following characteristics:
Composite sandwich panels The composition of composite panels is simple:
The scope of composite panels is quite large. They are used in the construction of commercial, sports, office and other facilities. The exceptions are schools and medical institutions.
Composite panels in the decoration of the facade of the building On a note! It should be noted that composite panels can be made from various kinds metal. So, very often galvanized or stainless steel sheets are used.
Also, these products may be different decorative forms. The most commonly used panels are brick.
Composite panels come in a wide range of decorative shapes and colors Consider what is an OSB sandwich panel and how it differs from aluminum. Unlike composite, SIP panels are used to create internal partitions of the room and roof. Material properties:
OSB sandwich panel is one of the most popular building materials. Such sandwich panels make the walls smooth and very warm. There is no need for a deep foundation, which can significantly save money and time.
It is worth noting that there are many types of decorative sandwiches that imitate the main types of coatings. They allow not only to quickly clad any building, but also to give it the necessary appearance.
Sandwich panels imitating other types of coatings
Brick panels are a self-supporting structure, which is used for facade decoration. They have the following benefits:
Sandwich panels allow you to quickly build a building or carry out finishing work The dimensions of the sandwich panels that go on sale have a certain value. Namely:
It should be noted that roofing products are larger. The size of composite panels does not differ.
Sandwich panel dimensions On a note! During construction, when it is required to finish a large area, the size and characteristics of this material can be ordered individually.
Before making the final choice, you need to pay attention to such nuances:
Good house building for a long time. 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 warm and secure home, which can easily withstand Russian frosts, can be erected 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 mistrust, progressive technology has established itself in the domestic construction industry, conquering developers with the speed of construction and quality that does not suffer from speed construction works. Turnkey sandwich panel houses are increasingly turning into an option worth considering and choosing.

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.

The panels are used for the construction of walls, interfloor ceilings and load-bearing partitions and also as a finishing material. Type 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.
The material is widely used in the installation of not only pitched roofs, but also other types. roof structures with an angle greater 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 required for roofing panels - durability and high load-bearing capacity.
Facade cladding with sandwich panels
Sandwich panels for the house are widely used for cladding the facade parts of houses, finishing window and doorways(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.
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.

For the outer layers, rigid sheet material is used with protective coating; most often it is:
Cink 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 impact 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.
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 Source pinterest.es
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 flammable, emits toxic substances in a flame, therefore it is not recommended for buildings with high demands fire safety.
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".
The quality of houses built using the sandwich panel technology directly depends on the reliability of the connection of the elements. Connections affect strength, appearance and thermal efficiency panel walls. In the arrangement of the elements, a connecting lock of the popular “thorn-groove” design (tongue-and-groove connection) is used.
Classic tenon-groove connection Source isobud.com
Bends (thorns and grooves) are formed during profiling external surfaces. Thanks to lock connection Panels are perfectly joined with each other, providing fast 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).
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.

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.

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).

Every year everything 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 houses made of turnkey sandwich panels, projects and prices of which are designed for wide range 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.

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.
