1-Inch Copper Pipe Insulation

Owens Corning 200239 is a fiberglass tube designed for 1-inch copper pipe with a 1-3/8-inch outside diameter. It arrives new with a tan ASJ facing and a pre-slit adhesive flap for quick installation. The product suits residential and light-commercial plumbing jobs that require thermal protection on hot or cold lines.

0 to 1000 Degree Operating Range

The insulation performs continuously from 0 degrees F up to 1,000 degrees F, covering most domestic hot-water and hydronic-heating temperatures. Its flame spread index of 25 and smoke developed index of 50 meet typical plenum-rating requirements for air-handling spaces. Builders needing higher temperature resistance or different fire ratings must select another material.

R-11.5 Thermal Resistance

A 1-1/2-inch wall thickness delivers an R-value of 11.5, reducing heat loss on hot pipes and preventing condensation on chilled lines. The three-foot length covers standard runs but requires multiple pieces for longer circuits. Projects demanding higher R-values or thicker walls will need a different specification.

Questions about this item

Should I choose the 1-inch or 1-3/8-inch size for my copper pipe?

The insulation is made for 1-inch iron pipe and 1-3/8-inch copper tube, so match the size to your pipe material.

What does the R-11.5 rating mean once the wrap is on the pipe?

R-11.5 shows the thermal resistance of the 1-1/2-inch fiberglass wall, reducing heat loss or gain through the pipe surface.

Is the ASJ facing plenum rated and what does the 25/50 flame spread index allow?

The ASJ facing is plenum rated with a 25 flame spread and 50 smoke developed index, meeting common building-code limits for exposed duct insulation.
