Millions of feet of PermaTherm EPS (rigid closed cell foam) pipe insulation systems have been successfully installed throughout the world. PermaTherm has developed a complete system for chilled water pipe insulation, cold service ammonia system and cryogenic insulation, for HVAC and mechanical insulation applications. At 1 lb/ft3 density, Permatherm brand 407 exceeds ASTM-84 25/50 requirements with a 5/50 Flame Spread/Smoke Development rating. At 2 lb/ft3 density, Permatherm brand 427 exceeds Class 1 ratings. PermaTherm has developed a proven track record for superior performance. Time after time it has been proven to be the most efficient insulation system in terms of cost versus performance.
PermaTherm produces the highest quality EPS pipe insulation available. Computer Numerical Controlled (CNC) cutting lines fabricate to any product shape. PermaTherm Expanded Polystyrene pipe insulation is superior in terms of cost and life-cycle performance when compared to alternatives such as fiberglass, cellular glass, and polyurethanes.
