Product Details

Modern constructions often require external cladding and rain screens to be held away from the building structure to allow ventilation and improve the building energy efficiency. This resulting cavity creates a serious fire protection threat to structures and people. The void acts like an open chimney and allows the fire to spread quickly both vertically and horizontally around the building.

The FF102/50 Fire Blocks for rainscreen systems are high expansion intumescent seals offering industry leading performance as Ventilated Cavity Fire Barriers / ‘Open State’ Cavity Fire Barriers. The products have undergone extensive fire testing, including NFPA285, and are suitable for use within the majority of construction types, enabling the versatile system to be specified with confidence and provide the installer with a simple, time saving and site friendly solution.

The FF102/50 Fire Blocks are rigid, high expansion intumescent strips encased in aluminum foil. The FF102/50 can be mechanically fixed both horizontally and vertically within ventilated cavities behind rainscreen or cladding systems to act as a cavity fire barrier.
