POLYTHERM is a fiberglass jacketed; spray applied polyurethane foam insulated piping system for above and below ground distribution of liquids from -320F to 250F. PERMA-PIPE's multi-directional filament winding process produces a high strength fiberglass reinforced polymer resin jacket (FRP) over the insulation for maximum protection from the environment. This high-strength fiberglass jacket is applied to systems having an outside diameter as large as 48 inches. Electric heat tracing is an option with this system.

POLYTHERM's spray insulation process assures void-free insulation. By applying insulation before the jacket is applied, complete visual inspection of the insulation is performed. This process assures void-free insulation and therefore, maximum thermal efficiency to provide optimum performance of cryogenic and heat thermal distribution systems. The POLYTHERM system is fully engineered to job specifications, thereby reducing field costs by providing custom made, factory-fabricated fittings which reduce the number of field connections as compared to the field kit method.
