SIKA Index Vapordiffuser V 4kg Roll | WPD Group

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.

It can be applied on concrete substrates and over existing bitumen roofing membranes. Weight: 2,0 kg/m2.
