OSB 4 - these OSB boards have the highest threshold of strength and moisture resistance.Sometimes OSB 3 acts as a roofing material or floor. They are used more often in construction for the construction of both facade and interior finishes. These boards combine strength and moisture resistance at a nice price. OSB 3 is one of the most popular board types.Less commonly, OSB 2 is used in the construction industry, and then only for internal structures. Such plates are used mainly for the production of furniture, sometimes for load-bearing elements. OSB 2 - has a low moisture resistance threshold and at the same time high strength.The advantage of these plates is their low price. This type of plate is often used in the assembly of light weight parts. OSB 1 is a board with the lowest moisture resistance strength.Each of them differs from others only in its indicators of moisture resistance and strength. In our country and the CIS countries, sandwich panels of the following sizes are used:Īcquaintance with the concept of OSB boards should begin with a general classification. Its thickness is 174 mm, width is 1250 mm, height is 2500 mm. The issue price of the SIP panel is 1,300 rubles per square meter. The thickness of the building material, and, accordingly, the price directly depends on the thickness of the insulation itself. Polyurethane foam how to start for sandwich panel Polyurethane foam is a poor conductor of heat and is easily flammable, but it has a high insulating threshold. But with a set of such important advantages, basalt insulation has a very low resistance to moisture. This insulation also tolerates biological and chemical effects well. Mineral wool practically does not burn and is also harmless to health. But at the same time, such material is very flammable and burns quickly. Possesses properties of water resistance and is not afraid of the sun. In addition, it is an environmentally friendly material. Polyfoam is positioned as a heater, distinguished by its durability. But if this is not possible, it is worth studying the main types of heaters and their characteristics.Īnd each of these heaters has its own advantages and disadvantages. When choosing sip panels, it is still better to seek help from specialists. The main material for the cover layer is usually "corrugated board" (galvanized steel coated with a polymer). For the manufacture of sandwich panels, only proven and suitable materials are used. A sandwich panel is a design that consists of a heater and a few words roofing material and is used as the main construction material for the construction of buildings of varying complexity of design.
