What is BROOF(t4)?
BROOF(t4) certification assesses a roofing system’s ability to resist external fire spread. The evaluation includes:
Surface Spread of Flame – Ensuring minimal fire propagation.
Burning Brands Resistance – Testing durability against burning debris and embers.
Heat Penetration – Measuring heat transfer prevention to underlying substrates.
This rigorous testing guarantees compliance with building regulations while enhancing real-world fire safety, protecting both property and lives.
