Fiberglass Pipe Insulation

This common insulation material is typically used on hot and cold water lines and in process piping. To use outdoors, add metal jacketing.

Tubes, elbows, and tees are formed to provide the best fit on pipe and are the easiest to install. If your pipe is larger than the sizes we offer, choose a sheet/strip.

Tubes have an all-service jacket (ASJ) made of kraft paper with an adhesive strip closure. Seal with reinforced insulation tape (sold separately).

Chemical-Resistant Cellular Glass Pipe Insulation

Very rigid with a 0% water absorption rate, this insulation is unaffected by corrosive environments, organic solvents, and most acids. It is typically used in chemical-processing systems and underground lines. Insulation is flame resistant, meeting ASTM E84 0/0 for flame and smoke. Seal with tape (sold separately). Outdoor and underground use require metal jacketing (sold separately).

Tubes have a kraft paper jacket with an adhesive strip for sealing.

Ultra-Insulating Low-Temperature
Polyisocyanurate Foam Pipe Insulation

This very rigid insulation offers the lowest heat-flow rate of our pipe insulation and restricts absorption of water, air, and gas. It is typically used in process piping and chiller plants and performs best in applications below 50° F. To use outdoors, add metal jacketing.

Tubes have a kraft paper all-service jacket (ASJ) that resists mold and mildew by allowing moisture to evaporate. They have an adhesive strip closure.
