Tenmat

Tenmat offers a range of ventilated fire barrier products to the construction market that can be used across a wide range of cavity sizes.  

Creating ventilation in rainscreen cladding systems improves a buildings energy efficiency, but with this comes the threat of rapid spread of fire, when in the situation of a building fire. Tenmat offer a range of products that control the spread of fire using intumescent ventilated fire barriers or ‘open state’ cavity fire barriers. They operate by rapidly expanding to seal the gap in the event of a fire but in normal condition, will maintain the cavity for ventilation.

Supplied as a 6.3 metre length and fire tested up to 30 minutes, it is a great solution for timber frame and masonry cavities. The intumescent, low profile design of the cavity fire barrier roll will not obstruct the ventilation chimney, unless activated, and is less likely to be damaged once installed. Installation is easy by simply stapling into position.
