Sika Index Vapordiffuser V - High-Performance Waterproofing
The Sika Index Vapordiffuser V is a premium APP modified bituminous roof membrane designed for professional waterproofing. This torch-applied solution remains flexible at temperatures down to -10 °C and is reinforced with high-strength glass fleece. The underside features 3.5 - 4 mm knobs covering roughly 35% of the surface, creating a semi-adhesion system that allows for the diffusion of residual moisture while distributing mechanical strain.
