TBA Intumescent Wrap for PVC & insulated pipes

Firefly lntustrap is a high pressure intumescent wrap, which comes in a 25m long coil, easily cut to the required length using a long bladed Stanley knife. Used to wrap around thermally lagged copper pipes and small PVC /HDPE Pipes. In a fire the intumescent will expand to replace the gap left by the thermal insulation and plastic pipes as they melt away/break down, maintaining the full integrity/insulation of the fire seal.
