Knauf Firecollar consists of a white coated circular steel shell that splits in two to fit around the service penetrations by means of a simple ’slide-lock’ system.
The steel frame contains a graphite based swelling material that reacts to heat and fills the opening from the melting plastic through-penetration in case of a fire.
Knauf Firecollar are designed to maintain the fire resistance of fire rated walls and floors where these are breached by continuous plastic pipes, and may be used in gypsum, masonry and concrete walls and floors.
