Owens Corning 147329 drain trap

3 ft fiberglass pipe insulation

This Owens Corning pipe insulation is a 3-foot length of fiberglass tube designed for 3-1/8 inch copper tube size. It features a 1-1/2 inch wall thickness with an R-value of 10.6 and an ASJ facing with a slit, adhesive, and flap for installation. The tan-colored insulation is plenum rated with a flame spread index of 25 and smoke developed index of 50. It operates effectively from 0 to 1000 degrees Fahrenheit.

Suited for high-temperature piping systems

This insulation suits contractors insulating copper piping in commercial or residential mechanical systems requiring plenum-rated materials. It fits 3-1/8 inch copper tube specifically and handles extreme temperatures up to 1000 degrees Fahrenheit. Buyers needing different pipe diameters, lower temperature ratings, or non-ASJ facing materials should look at other options. The slit adhesive flap design simplifies installation on straight pipe runs.

R-value 10.6 thermal performance

The R-value of 10.6 determines the thermal resistance this insulation provides for the covered piping. This rating indicates its capacity to reduce heat loss or gain on hot and cold water systems operating within the 0 to 1000 degree Fahrenheit range. The fiberglass material and 1-1/2 inch wall thickness achieve this performance level for the specified 3-1/8 inch copper tube size.
