Description
Cast in Concrete Fire Sleeve
The cast in concrete fire protection sleeve is a cylindrical metal tube, for use around services in fire-rated concrete floors or walls. A circular oblong or square metal collar with an intumescent lining, designed for setting into concrete to allow services to pass, including cables, pipes, etc. Fitted with an intumescent, fire-resistant sponge to provide passive fire protection. Fastened to reinforcing mesh with wire ties, then cast into the concrete. After casting and before the concrete has set, the ends are simply wiped clean with a damp cloth.
Supplied with removable end-caps made from acoustic sponge and fireproof card, easily cut to any size with a sharp blade. Acoustic end caps provide excellent attenuation to airborne sound. Metal end caps are an alternative solution for use after setting, allowing heavy traffic to flow. Sleeves are suitable for use in either domestic or industrial applications, such as computer rooms, hospitals, laboratories, etc. In a fire, the intumescent liner expands to fill the gap around services and blocks passage of smoke and fire.
