About Selecting Thermal Insulation

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.

Sheets/strips with foil facing reflect heat away from pipe. The foil facing is also known as FSK. Seal with reinforced HVAC tape (sold separately).
