Fire Collars

FireClose pipe collar protects the integrity of fire compartments where pipes (and cables) pass through walls, floors and ceilings. Without a protective collar device, a fire would soften and then consume PVC, PVC-U and polypropelene pipes – leaving an opening for air to fuel the fire and for the fire to escape from the compartment.

The collar is hinged so it can be fitted to existing pipes and is locked with a steel clamp. It contains several layers of high pressure intumescent compound which are flexible – allowing a comfortable fit over nominal pipe sizes: 55, 82, 110, 125 and 160 mm. During a fire, the pipe softens and the intumescent material expands to completely fill the gap left by the pipe. FireClose can be cast-in or surface-mounted (brackets are included) in either vertical or horizontal planes. It is slim enough to fit into narrow corners which would be too tight for larger closers. It has been independently tested to BS 476–20 to give up to 4 hours fire resistance, depending upon the substrate. For non-standard sizes please see our FireWrap product page, in the related products section below.

Intumescent activation temperature is approximately 180°C.
