The low-profile pipe collars are designed to be installed in concrete, brick, or masonry fire-rated walls and floors, and fire-rated plasterboard walls. The Allproof pipe collars consist of intumescent material encased in a steel surround with fixing tabs. The advanced intumescent technology allows Allproof to achieve a very low-profile height of only 27mm for the 25–80mm pipe collars.
When fire occurs, the intumescent material expands against the steel surround as the flammable plastic pipe running through the collar melts and burns away. The steel casing acts as an excellent heat sink, ensuring fast activation of the intumescent, forming a stable fire-resistant plug, maintaining both fire integrity and insulation.
Pipe collars are designed to be exposed in a wall or floor application (i.e., face-fixed). The collars should always be fixed to the underneath of the concrete floor. In wall situations, one collar should be used on each exposed side of the fire-rated wall.
Designed, made, and tested in New Zealand for NZ applications.
