Protecta FR Collars
Collars are a surface mounted solution used to firestop around combustible pipes, metal pipes with combustible insulation and cable bundles, penetrating fire resistant walls and floors. Collars contain an intumescent graphite polymer within a powder coated steel sleeve. In a fire, the intumescent material rapidly expands, generating a high pressure seal which closes off voids left by molten plastic and combustible materials. The resulting char forms a robust seal preventing the passage of fire, smoke and hot gases.
