Air Handling Insulation

Duct Liner Fiberglass duct liners are blankets or boards of glass fiber insulation with either a coating or a fibrous mat on the surface facing the air stream. They are used as a thermal and acoustical insulation and are applied to the inside of sheet metal ductwork with metal fasteners and adhesives. They are available in a variety of densities and thicknesses.

Duct Board Fiberglass duct boards are widely used in residential and light commercial HVAC systems. The outside surface of the board is a reinforced aluminum/kraft laminate that serves as the air barrier and water vapor retarder. Fiberglass duct board systems control heat loss or gain through the duct wall, help to control moisture condensation, and are substantially airtight when properly fabricated and sealed.

Duct Wrap Duct wrap is a flexible, resilient blanket that is applied to the exterior of sheet metal ducts. It can be easily cut and fitted to achieve a neat, thermally effective exterior insulation blanket over rectangular, round, oval, or irregularly-shaped duct surfaces. Duct wrap is factory laminated to a vapor retarder facing and is available in various thicknesses and densities. When applied to the exterior of metal ducts, this product controls condensation and reduces heat loss or gain.
