About Selecting Thermal Insulation

Compare R-value and temperature range to find the insulation material that best suits your application.

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).
