SIP panels - strong and lightweight wall material

The market of building materials is quite oftenreplenished with some new items. The fashion to build houses from CIP panels came to us quite recently. It is very interesting both in terms of its design and performance characteristics of the material.

Panel construction

The SIP panel consists of two OSB boards (OrientedStrand Board) and the rigid expanded polystyrene laid between them. OSP, in fact - a more modern, environmentally friendly analogue chipboard. The difference between these two materials is that the OSB is made from fine chips, which is glued together with resin under high pressure, and not from waste products like chipboard. Unlike the latter, the Oriented Strand Board (in translation - a plate with oriented chips) contains no harmful formaldehyde than a conventional wooden massif.

Despite the light weight and apparent brittleness, CIPpanels - very durable material, capable of withstanding enormous loads. If you put this plate vertically, you can put a load of up to 10 tons per 1 m2 of panel on top. Imagine a five-story building, in which the first floor is made of such panels, and the rest of the brick is a meter and a half. That's about the weight they can withstand.

In the horizontal position of the CIP panel alsostrong enough. The weight that they can hold without deflection is two to three tons. However, in this respect, their characteristics are not particularly distinguished. In addition to strength, they have remarkable thermal insulation properties and a high level of noise absorption. In addition, the OSB is not afraid of moisture and mechanical damage.

Application

The construction of houses from CIP panels involvesfirst of all, the use of this material for the construction of external and internal walls. Sometimes they are used as slabs of zero and attic floors, as well as roof finishing. You can not make them floor-to-ceiling. The fact is that these panels very well miss direct shock noises (roughly like a drum). For zero and interfloor overlapping, they are also used quite rarely. To the panel does not bend, it is made narrower than the wall, and put on beams. Therefore, most often it is more convenient to arrange conventional overlapping.

Convenience, for example, of a zero overlap of a CIPThe panel can only be that you do not need to arrange a rough floor. Laminate or other finishes are placed directly on the OSB plate. For walls, this material is an ideal option. The house can be assembled for 2 - 3 weeks by the forces of only two people. The foundation is stuffed with a bundling bar, then corner panels are installed with level control. Then they put all the rest. They are fastened with usual self-tapping screws. All joints and crevices are sealed with foam. Cut slabs can jigsaw, and polystyrene - a thin wire, parallel to the cuts on the OSB. From the inside, walls are usually finished with plasterboard without using a guiding profile, and then pasted with textured wallpaper.

Many have already built houses using CIP wallspanel. Reviews about them are often positive. For example, even in places where the air temperature reaches -50 g in winter. Celsius, in the buildings of this material the heat is very well preserved. In addition, such panels are easy and do not require the erection of a powerful foundation under the house.
