SIKA Index Vapordiffuser V 4kg Roll

Vapordiffuser/V is an APP modified bituminous roof membrane, torch applied, flexible at -10 °C and reinforced with a glass fleece. The underside has thicker knobs with 3,5 - 4 mm, which covers almost 35% of the surface and allow the diffusion of the remaining moisture of the surface. To ensure the application, the underside has a polyethylene burn-off film. This semi-adhesion is also used to distribute and soften mechanical strain on the laying surface. It can be applied on concrete substrates and over existing bitumen roofing membranes. Weight: 2,0 kg/m2.
