VST Air and Light Duct

The VST air and light ducts are formwork elements made of 24mm thick cement-bonded particle boards (CBPB). With this tailor-made prefabricated solution, both the direct and the subsequent installation of air and light ducts is quick and easy. The VST air and light ducts can be thermally decoupled, so that there is no need to insulate the element and thus save time and money. 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 air and light ducts have fire protection class A2-s1, d0.
