Our Fire Collars are designed to maintain the fire resistance of fire rated walls & floors where they are penetrated by plastic pipes.
They consist of a stainless steel shell which contains a heat reactive unexpanded graphite based intumescent material. Each collar is fastened to the wall using the integral “fixing lugs” at the base of the unit.
The unexpanded graphite material inside the collar expands up to 8 times its current volume restricting the passage of fire within plumbing penetrations.
FEATURES
- Provide up to 4 hours fire resistance
- Unaffected by moisture
- Standard and non-standard sizes available
- 10 years warranty on the intumescent material
Installation Instructions Fire collar can be surface mounted, or they can be cast in or semi-cast in when fixing space is limited.
- WALL FIXING: Where there is a fire risk on both sides of a wall, or the direction of fire risk has not been determined, then a Fire Collar should be fitted to both sides of the wall.
- FLOOR FIXING: Penetrations through floors require a fire collar fitted to the underside only of each penetration.
