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.
Elbows and tees with PVC jacketing seal using reinforced HVAC 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).

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.
