Material
BIT – Version with weather-stably modified base unit and laminated bitumen connection sleeve. A stainless steel flange connection is used to secure the VaporBase. The base unit has been modified to make it weather-resistant. UV-stabilised, resistant to heat degradation and oxidative ageing as well as cold impact resistant. With a thickness of 4 mm, the connection sleeve consists of talc-coated elastomer bitumen with an integrated carrier insert, making it ideal for forming a reliable connection with bitumen roofing membranes.
