PUF PIR Panel Slab Boards
CFC Free PUF/PIR Pipe Section & Boards
“SRV Foam” ” Rigid PU foam cored pipe sections manufactured and are available in varied sizes and densities. Being CFC-free polyurethane Foam, it is “Environment Friendly” and has excellent dimensional and thermal insulation
“SRV Foam” ” Rigid PU foam cored pipe sections manufactured and are available in varied sizes and densities. Being CFC-free polyurethane Foam, it is “Environment Friendly” and has excellent dimensional and thermal insulation properties together with compressive strength.
PIR has low smoke emissions and will not melt or dip in a fire. PIR being Polyisocyanurate foam, has a higher hot surface performance up to 150°C compared to 110°C of normal Polyurethane foam.
