Fire Barriers for Ventilated Cavities

Modern constructions often require external cladding, curtain walls 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 the event of a fire.

These innovative Fire Barriers are suitable for a variety of Cladding Applications with cavities ranging from 0.6" to 20" and have been tested in both Timber Frame and Non-combustible Constructions.
