Fire Rated Cavity Seals.

Many external wall systems are designed with an open cavity to provide back ventilation. The cavity acts like an open chimney to allow for moisture dissipation and to create a back pressure to repel rain ingress.

However in a fire situation this chimney effect creates an open path for the hidden spread of fire both vertically and horizontally behind the external wall system.

The Astroflame range of fire rated cavity seals will maintain the ventilated cavity in normal conditions, leaving a continuous free air space, but in the event of a fire, the intumescent ventilated fire barrier will quickly expand to seal off the cavity to prevent the spread of fire.

Astro Clad Ventilated Fire Barrier ‘Open State’ Cavity Barriers are designed to prevent fire spread and provide compartmentalisation in the external façade. It is essential that the correct fire barriers are specified and installed, therefore to place your Cavity Barrier order please fill in and email us the following interactive PDF form:
