Our new Cap sheet is a Broof (t4) tested membrane. When it comes to flat roofs, fire safety is non-negotiable. It is the gold standard in fire performance of roofs in the UK. Broof (t4)is the highest European fire safety classification for roofs, indicating superior resistance to external fire exposure (burning brands, wind, and radiation). It proves a roof system restricts flame spread and prevents penetration for at least 60 minutes, ensuring compliance with UK Building Regulations.
