Cavity Fire Barriers


The Envirograf® Cavity Barrier range fully satisfies the requirements stated in Document B of the Building Regulations. According to Document B of the UK Building Regulations fire barriers must be installed in cavity areas that are vulnerable to the spread of fire.

Using the correct passive fire cavity protection system within a building is crucial, in the event of a fire, intumescent fire barriers activate and seal holes, penetrations and cavities, preventing the spread of fire and smoke, thereby fulfilling UK regulations.
