Pipe Insulation

We stock a wide range of foam and fiberglass types pipe insulation for pipes up o 4" in size, including for copper, PEX, black/galvanized/stainless steel, brass, cast iron and PVC/ABS (Sch 40/80) pipes. Both insulation types are widely used for minimizing heat loss, preventing condensation and dampening sounds.
Foam pipe insulation is a popular choice for all types of plumbing, heating and cooling applications - except steam (and other high-temperature applications).
Fiberglass pipe insulation is a popular choice for steam pipes and locations where fire code compliance is required or desired.
Pipe Outside Diameter (OD) = Insulation Inside Diameter.
For example, 7/8" ID insulation works for 3/4" copper/PEX/CPVC pipe or 1/2" steel/plastic pipe, since all these have the same OD equal to 7/8".

Foam vs Fiberglass Pipe Insulation - What's the difference?

Foam, or more specifically, closed-cell polyethylene foam insulation is a virtually universal choice for majority of plumbing, heating and cooling applications due to solid performance (great insulating properties and resistance to moisture and condensate), making it ideal for typical hot and cold water pipes, baseboard/radiator/boiler pipes and others commonly found in residential applications.
Fiberglass insulation differs from foam type mainly by it's fire-resistant properties (suitable for buildings where fire-resistant insulation is required by code or desired) and high temperature resistance (much higher than foam), making it ideal for steam pipes.
