Cavity fire barriers are designed to inhibit the spread of fire and smoke in concealed spaces, typically within roof voids and above suspended ceilings. There are two generic types available:-

Firstly, the traditional mineral fibre type which provides up to 120 mins integrity and 120 mins insulation, with good acoustic performance.

The second is the lightweight woven fabric non-respirable type, which provides fire & smoke barriers only, up to 2 hours, and insulated barriers which provide up to 1 hour integrity with 38 minutes insulation.

Benefits to the Product:

• High insulation performance limiting heat transfer through the barrier, preventing ignition of combustible materials an the adjacent areas
• Penetration Management
• Suitable for continuation of compartment wall within void
• Positively fixed
• No maintenance required
• Can accommodate access hatches and fire doors

Applications:
Compartmentation of structures within voids to provide up to 120 Mins integrity and 120 mins insulation between areas. Reduction of transmitted sound between rooms of up to 50dB.

Appearance:
For use in concealed areas, either mineral fibre (may be foil faced) or woven fabric appearance.
