Polyolefin/XLPE (Duct Insulation)

Polyolefin closed cell tubular insulation was developed in Europe in the 1970s. Much of the development work was done in Belgium. It was first introduced in the United States in 1979 as a do-it-yourself insulation in semi-slit, three-foot lengths. During this time, the country was undergoing our first energy crisis, with government rebates for home insulation improvement, so polyolefin insulation quickly caught on as a pipe insulation for domestic hot and cold water.
Polyolefin insulations are easy to work with. No special tools or protective clothing are required. The most predominantly used form is preslit/preglued, which almost eliminates the need for additional adhesives on most jobs. It can be easily fabricated in the field with a sharp knife.

Common Applications Include The Following:

  • Hot and cold water (domestic and commercial)
  • Roof drains
  • Cold process pipes and equipment
  • Heating, ventilating, and air-conditioning (HVAC) equipment
