RAINSCREEN FIREBLOCK

FIRE BARRIERS & FIRE BLOCKS FOR VENTILATED CLADDING & RAINSCREEN SYSTEMS

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.

TENMAT’s range of Intumescent Fire Barriers are designed to maintain the open, ventilated cavity in normal conditions but will expand to seal off the gap in a fire situation and serve as a fire block. TENMAT Fire Barriers are suitable for a variety of Cladding Applications with cavities ranging from 0.6” to 19.6” and have been tested in both combustible and non-combustible constructions.

The FF102/50 Ventilated Fire Barriers are high expansion intumescent seals offering industry leading performance as Ventilated Cavity Fire Barriers / ‘Open State’ Cavity Fire Barriers with air gaps of up to 2″.

The VFB Plus Ventilated Fire Barrier is a ‘Open State’ Cavity Fire Barrier system for ventilated cavities of up to 19.6″ (500mm) which employs a high expansion intumescent seal fixed to TENMAT High Density Mineral Wool.
