Our whole building system SIPsCZ and its individual elements have a certificate and certificate in the field of fire resistance by an authorized person in the Czech Republic. They are subject to and meet stringent EU fire standards, which are a prerequisite for the construction of residential buildings.
The high strength of the middle layer of the OSB 4 TOP ensures a stable and highly load-bearing profile. It meets the most demanding construction requirements. Alternatively, the fire resistance can be determined by the burn-off rate. At a panel thickness of 30 mm, OSB 4 TOP boards have a fire resistance of more than 30 minutes and at the same time achieve a K230 encapsulation according to EN 13501-1 in the event of a fire. This makes the OSB 4 TOP visible cladding even in the case of fire protection requirements. In family houses, the standard layer of fireproof plasterboard is used as the final layer. It is installed directly by contact, without the need for pre-walls.
