Pre-Insulated Pipe System

POLY-THERM® Premier Engineered Series has been tested and passed the ASTM E-84 Class 1 requirement for fire retardancy (both flame & smoke).

POLY-THERM is a non-flammable, fabricated with tough fiberglass reinforced (FRP) outer jacket and void-free polyisocyanurate (PIR) foam insulation. POLY-THERM’s FRP jacket provides a seamless waterproof jacket protecting against corrosion under insulation while delivering maximum thermal efficiency and optimum performance in the most demanding projects, such as cryogenic, LNG, and LPG.

The outer jacket’s standard color is available in white or black.  Also, available in any color, please ask PERMA-PIPE for more information.
