The building materials market is often replenished with some new products. The fashion to build houses from SIP panels came to us recently. This is a very interesting material both in its design and performance.
Panel deviceSIP panels consist of two OSB boards (Oriented Strand Board) and hard polystyrene foam laid between them. OSB, in fact, is a more modern, environmentally friendly analogue of particleboard. The difference between the two materials is that the OSB is made from fine wood chips that are glued together with resin under high pressure, and not from industrial waste like chipboard. Unlike the latter, Oriented Strand Board (in translation - a plate with oriented wood chips) contains no more harmful formaldehydes than ordinary wood.
Despite its light weight and apparent fragility, SIP panels are a very durable material that can withstand huge loads. If you put such a plate vertically, you can put on top a load weighing up to 10 tons per 1 m2 of panel. Imagine a five-story building, in which the first floor is made of such panels, and the rest of the brick is one and a half meters. That's about a mass they can withstand.
In horizontal position, SIP panels are also quite durable. The weight that they can hold without deflection is two to three tons. However, in this regard, their characteristics are not distinguished by anything special. In addition to durability, they are distinguished by remarkable heat-insulating qualities and a high level of sound absorption. In addition, the OSB is not afraid of moisture and mechanical damage.
Application
The construction of houses from SIW panels involves primarily the use of this material for the installation of external and internal walls. Sometimes they are used as slabs of zero and attic floors, as well as roof trim. It is impossible to make interfloor ceilings from them . The fact is that these panels very well pass direct shock noises (approximately like a drum). For zero and interfloor ceilings, they are also rarely used. So that the panel does not bend, it is made narrower than the wall, and placed on the beams. Therefore, more often than not, the device of conventional ceilings is more appropriate.
The convenience, for example, of zero overlap from a SIP panel can only be that you do not need to arrange a rough floor. Laminate or other finishes are laid directly on the OSB plate. For walls, this material is ideal. The house can be assembled in 2 - 3 weeks with the help of just two people. A strapping beam is filled on the foundation, then corner panels with level control are installed. Then they put all the rest. They are fastened with ordinary screws. All joints and cracks are sealed with foam. Plates can be cut with a jigsaw, and polystyrene foam with a thin wire drawn parallel to the cuts at the OSB. Inside, the walls are usually finished with drywall without using a guide profile, and then pasted with textured wallpaper.
Many have already built houses using SIP panels for walls. Reviews about them are most often positive. For example, even in places where in winter the air temperature reaches –50 g. Celsius, in buildings made of this material, heat is stored very well. In addition, such panels are lightweight and do not require the construction of a powerful foundation under the house.
