Icopal Fastsafe Underlay

Icopal FastSafe is a fixed underlay designed for single-layer coverage and compatible with various roofing materials, including concrete and clay tiles, slate tiles, and metal roofs. This system ensures long-lasting durability and tightness during the construction phase and the remaining life span. It offers high strength, resistance against impact damages and perforations, and accommodates minor substrate movements. The SBS-bitumen coating provides cold weather flexibility, preventing cracks in low temperatures and extending the roof's lifespan.
