- Product Summary
- ROOFCRAFT BASE® is a factory laminated composite roofing base sheet and support panel. The base sheet on the upper surface of the panel is made from a strong reinforcing mat (available with 180g. polyester core or 95g. fibreglass core). The base sheet is coated with a SBS modified bitumen. The base sheet allows superior elasticity and moisture resistance with exceptional cold weather flexibility. Both base sheets (180g. polyester or 95g. fibreglass) have thermo-fusible film on the upper surface and sand on the lower (laminated) surface for better adhesion.
- The lower composition of ROOFCRAFT BASE® is a SECURpan® fire-retardant high density fiberboard panel. The SECURpan® fiberboard panel is made from 100% recycled wood fiber. The fiberboard eases the installation with its light weight and it advantageously complies with environment focused projects (LEEDTM and Green Building), with a 60% content of post consumer and 40% content of post industrial. SECURpan® fire retardant fiberboard panel has a flame and smoke spread rating lower than 25.
