Curtain Wall Fire Stop Board

ABM® Curtain Wall Fire Stop Board is designed specially for all types of curtain walls. The product has higher temperature resistance, higher melting point, longer fire resistance time and smaller high-temperature linear shrinkage.

CFS series can be applied not only as the fire and smoke barrier between curtain wall and floor slab or curtain wall and partition, but also as the barrier between other construction gaps around wall penetration pipes or floor penetration pipes. In order to enhance the smoke barrier capability of CFS series, fire proof aluminum foils can factory-laminated to the rock wool board.
