The 150 – 160mm fire collar consists of a continuous pressed stainless steel flexible shell containing high-performance graphite-based intumescent material. This reacts under heat to exert pressure on the pipe as it softens, forming a carbonaceous char that creates an effective insulation plug, preventing fire from passing through to the adjoining compartment
The intumescent fire sleeve is designed to be used where a plastic pipe penetrates a fire rated wall or floor. For vertical pipework, one unit should be installed to the underside of the floor. For horizontal pipework one unit should be fitted to both sides of the wall. The fire collars have also been tested generally in accordance with the BS EN 1366-3: 2009 fitted to a plasterboard ceiling/timber floor both direct to the plasterboard.
The intumescent fire collar has been rigorously tested to BS EN 1366-3 (the fire resistance test standard for service penetrations) and classified to EN 13501-2 (fire classification of construction products and building elements). The fire collar has been fire tested in a variety of applications with some achieving 240 minutes* Integrity and Insulation fire resistance (EI 240), delivering a reliable penetration seal for plastic pipes through walls and floors. The intumescent fire collar has built in fixing lugs which are used to secure it to the structure.
*EI 240 was achieved using specific testing configurations. Please check the tested scope of application to ensure suitability for specific site conditions.
