The VST roof dormer is a formwork element that consists of 24mm thick cement-bonded particle boards (CBPB). Thanks to this precisely fitting solution for the roof connection quick, professional and long-lasting installation is possible. All types of breakthroughs and openings as well as the installation of built-in parts (e.g. electrical wire) are also carried out at the factory. The VST elements are transported to the customer‘s construction site and moved there according to the assembly plan and then poured with concrete. The concrete core connects to the formwork element; stripping is not necessary. After the core concrete has hardened, the formwork element itself does not assume any load-bearing function.
VST roof dormer have fire protection class A2-s1, d0.
