Services   >>   Passive Fire System   >>   Cavity Smoke Barriers

The purpose of a cavity barrier is to prevent the spread of smoke and flame from penetrating and/or moving within a concealed space in a fire compartment.

In fire situations, smoke usually kills more people faster than heat, flames or structural collapse. Most modern buildings today have an engineered smoke control system which frequency involves the use of smoke reservoirs by means of constructing smoke channelling screens and curtains. Smoke reservoirs are used to prevent the lateral spread of smoke and to collect smoke for removal.


Smoke curtains and screens must meet the requirements of BS7346: Part 3: 1990, which requires the screen to withstand a fire temperature of 600oC (-+20oC) for aminimum of 30 minutes. We offer a permanent, easy to install, maintenance free and cost efficient method to meet and exceed the requirements of the above standard.
