Description

This 110mm Intumescent Pipe Collar is a critical component for passive fire protection in commercial and residential buildings. It is designed for use with plastic pipes (such as PVC, PE, and PP) that penetrate fire-rated walls or floors. The collar is engineered to stop the spread of fire for up to 4 hours in both vertical and horizontal applications. It features a robust stainless steel outer casing and utilizes an intumescent material that expands aggressively when exposed to heat, crushing the melting pipe and sealing the penetration point. The intumescent material is reliably unaffected by water, non-flaking, and difficult to tear. Installation is quick and easy thanks to the tab closing device and welded lugs, allowing it to be face-fixed on various structures. This product is suitable for soil, waste, and drainage 'above ground' applications and is approved for use on concrete, masonry, and plasterboard partitions. It includes a 10-year guarantee.
