Thanks to modern production technology and competent combination of several building materials, we can allow building a solid structure for building walls and floors with high thermal insulation. Nowadays, the construction of residential houses and holiday cottages are increasingly focused on efficiency, environmental friendliness and speed of erection of structures. An excellent material, and one of the leaders in terms of performance and installation are self-supporting insulated panels or SIP (Structural Insulated Panel).  A structural insulated panel has the form of briquettes with the possibility to cut out part of it in any form. The composition of the panel consists of two main components.
The external protection is made of OSB and internal filler in the form of polystyrene. In turn, there is a coating made from wood chips, compressed under high pressure, which perfectly protects the insulation, inside the SIP-panel. Expanded polystyrene is used in the manufacture of building construction has increased stiffness performance that enables high-strength panels.
