This study analyzes US demand for insulation by material, market, and region. Data is given in a variety of units, including dollars, pounds, square feet, and square feet of R-1 equivalent. Both thermal and acoustic insulation are included in the scope of this study.


Materials broken out include:

  • fiberglass, including batts and blankets, loose fill, rigid boards, sill sealers, water heater and pipe jackets, and specialty pipe and duct wraps
  • foamed plastics, including rigid polyurethane (PUR) and polyisocyanurate (PIR) board, spray polyurethane (SPF), extruded polystyrene (XPS), expanded polystyrene (EPS), phenolic, elastomeric, polyolefin, and melamine
  • cellulose, including blow-in and spray applied
  • mineral wool, including slag wool and rock wool sold as blankets, batts, felts, loose fill materials, and a number of specialty forms
  • reflective insulation and radiant barriers
  • other materials (e.g., perlite and vermiculite)

The major market segments analyzed are:

  • residential buildings, including all single-family (including manufactured homes) and multifamily dwellings, including both new and retrofit applications
  • commercial buildings, includes demand for insulation installed during new construction or the retrofit of offices, industrial/manufacturing, retail and wholesale, lodging, educational, healthcare, religious, transportation, and all other commercial buildings
  • industrial and plant equipment, both OEM and onsite, including coverings for machinery, boilers, pipes, and tanks
  • HVAC/air distribution equipment, both OEM and onsite, including coverings and linings for HVAC equipment and duct work
  • appliances, including insulation installed at the manufacturers’ level for refrigerators, freezers, dishwashers, and clothes washers and dryers
  • transportation equipment, encompassing OEM demand for insulation in the industries for automotive, aerospace, marine, rail, refrigerated transport vehicles, and all other transportation equipment
  • other insulation markets (including insulated coolers and thermoses, insulated packaging, furniture, bedding, nonbuilding/infrastructure construction, and heavy machinery)

Materials are also broken out by product form and, for foamed plastics, by type of resin. Additionally, mineral wool is broken out by type.

The residential and commercial building markets are further segmented by project type (i.e., new building and retrofit). The commercial building market is also broken out by building type (e.g., office, retail and lodging, institutional, industrial, and all other commercial buildings).

Demand for insulation is also broken out by US geographic region and subregion.
