Safety at the forefront

Passive cavity fire barriers are an accepted method to support the achievement of fire safety requirements. These functional requirements are defined within UK Building Regulations and further practical guidance is described within ADB. Strategies to remediate at risk buildings are latterly considering passive fire control, including cavity fire breaks, in addition to the façade panel and insulation.

Cavities in the construction of a building provide a ready route for the spread of smoke and flame, which can present a greater danger as any spread is concealed.
