Cavity Fire Barriers for Facades

Fire-tested for fire-stopping performance

Tenmat have developed and fire-tested a range of fire-stopping cavity barriers for facades to allow architects to specify high-level products, which meet the regulations necessary for building safe environments.

Passive fire protection is essential in high-rise developments, such as apartment blocks, where there are multiple dwellings. In this type of property, the risk of fire spread is increased, therefore passive fire protection should be thoughtfully considered during the planning phase.

Cavity Fire Barriers for Facades

Continuous testing ensures best-in-class performance

Our products can be specified through NBS, and are being continuously tested, which ensures that the range is the best on the market, as well as having the trust incorporated by being tested by third-party fire test laboratories.

Our technical support is in the form of qualified fire engineers who are available to support on a project-to-project basis, as well as having a regional technical sales team. This gives you the confidence that building regulations are fully understood and adhered to.

All our products are tested to the relevant industry standards, such as TGD19 for open-state cavity barriers and EN 13501-2:2016 for closed-state cavity barriers. These products enable you to meet the requirements of Approved Document B. Tenmat Cavity Barriers are readily available through all distribution routes.
