Rockwool Firepro 2 hr stop Pipe Collar

Tested to the harmonised European Standard EN 1366-3:2009, Rockwool FIREPRO® Pipe Collar CE provides up to 4 hours fire stopping in rigid floor constructions and up to 2 hours fire stopping in flexible/rigid wall constructions. The penetration seal is certified to internationally recognised standards such as Certifire and CE marking. Rockwool FIREPRO® Pipe Collar CE is slim in design (depth 30mm or 40mm) allowing it to be installed around a service where space is restricted. FIREPRO® Pipe Collar CE can be installed on flexible wall, rigid wall and rigid floor constructions. When used around plastic combustible pipes, FIREPRO® Pipe Collar CE will form a penetration seal to reinstate the fire resistance performance of the wall or floor construction. FIREPRO® Pipe Collar CE consists of a corrosion resistant powder coated steel sleeve, containing a flexible graphite based intumescent liner which is manufactured to suit standard diameter plastic pipework. Under fire conditions, the intumescent material within the collar expands, crushing the pipework and closing the void left by the pipework, preventing the passage of fire.
