I have a metal pipe which is insulated with foamed insulator, do I need to install a collar for this application?
Yes, the insulation material will at somenpoint be affected and consumed when exposed to elevated temperatures.nTherefore, when this insulation material is consumed, the void between thensupporting construction and the metallic service can be exploited by fire,ncompromising the fire resistance of the wall or floor. We recommend that thisnfire stopped using a Pyroplex fire collar.
