Pre-Insulated Pipe System


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

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 and thermal distribution systems.

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