Tenmat Cav Guard 65 6mm x 75mm x 6.3m

Tenmat CavGuard 65

Tenmat's CavGuard Roll 65 is a cavity fire barrier designed to firestop the cavity behind external walls consisting of outer substrates of masonry or brickwork. The low smoke zero halogen highly expansive intumescent material allows ventilation to be maintained in non-fire conditions.

The CavGuard Roll 65 is specially designed and made from a flexible material, allowing it to be provided as intumescent material rolls. With a thickness of only 6mm, the low profile design offers significant space and labour saving over traditional cavity socks, whilst also ensuring the external cavity is left unobstructed and free to ventilate. It is also covered with a protective layer of polythene for ease of handling and to protect it from water.

In the event of a fire the CavGuard Roll 65’s intumescent material will expand to close the external wall cavity, providing effective fire resistance, for integrity (E) and insulation (I) for 60 minutes* depending upon the construction of the external wall cavity. The CavGuard Roll 65 is designed to close off a total cavity of 65mm which allows for building tolerances of up to 15mm (above the typical maximum cavity
ventilation requirements of 50mm).
