Types of Duct Insulation

The five types of insulated air duct systems described in this guide can be used to meet all widely used architects’ or engineers’ specifications, local codes, owners’ comfort control requirements, installed and life cycle cost criteria, or the contractor’s crew skill levels and shop fabrication resources.


Duct Wrap Insulation

Fiberglass Ductwrap is a thermal and acoustical insulation for wrapping commercial and residential interior HVAC ductwork.


Flexible Blanket Duct Liner

Fibrous glass duct wrap insulation is designed for application to the exteriors of commercial and residential sheet metal heating, ventilating, and air-conditioning ducts and plenums operating at temperatures between 40˚F (4˚C) and 250˚F (121˚C). Duct wrap insulation reduces heat loss or gain through duct walls, conserving energy and controlling moisture condensation. Fibrous glass duct wrap insulations are useful in situations where acoustical performance is not an issue. Fibrous glass duct wrap insulations are flexible, resilient, light-density blankets of glass fibers factory-laminated to vapor retarder facings. These products are easily cut and fitted to achieve a neat, thermally effective insulation blanket over the exteriors of rectangular, round, oval, or irregularly shaped ducts. Fibrous glass duct wrap insulations are manufactured to comply with ASTM C 1290, Flexible Fibrous Glass Blanket Insulation USed to Externally Insulate HVAC Ducts.


Duct Insulation Boards

Fibrous glass insulation boards are also available for application to the outside of sealed sheet metal ducts, housings, and plenums. These are available unfaced, or with reinforced foil (FSK) or all-service jacket (ASJ) vapor retarder facings, in a range of densities and thicknesses. Some are flexible enough to conform to curved surfaces such as large round or oval sheet metal ducts. Fibrous glass insulation boards can be used in applications operating within the temperature range of 0°F (-18°C) to 450°F (232°C). Fibrous glass insulation boards are manufactured to comply with ASTM C 612, Standard Specification for Mineral Fiber Block and Board Thermal Insulation.


Fibrous glass insulation is used in air duct systems for four basic reasons:

Temperature control - Delivery of heated or cooled air at comfort levels suited to building occupancy requirements.

Acoustical control - Absorption of noise generated by central air handling equipment and movement of air through the ducts, as well as “cross-talk” carried by ducts from one space to another.

Condensation control – Prevents condensation in or on ducts when installed R-value recommendations are followed, reducing the likelihood of moisture damage to ceilings and other interior finishes.

Energy conservation - Reduction of HVAC system operating costs by controlling heat loss or gain through air duct walls, helping systems run more efficiently.


HVAC systems typically operate with internal air temperatures between 40˚F (4˚C) and 250˚F (121˚C). Systems operating outside this range are not considered in this guide, except that fibrous glass insulation boards may be used in systems operating at internal air temperatures between 0˚F (-18˚C) and 450˚F (232˚C).


Duct Insulation Price Costs

The cost of duct insulation varies greatly depending on a number of factors including the type and thickness of the insulation, the ease of access to your ducts and the cost of labor in your area. The average cost of duct insulation is between INR 55 - INR 280 per square foot.


Our HVAC Insulation Category is made up of a wide variety of materials used to insulate HVAC ductwork.  We offer a great selection of HVAC duct insulation products from leading brands.  Below are a few of the subcategories for these HVAC Insulation materials:

  • Board Insulation: All of the HVAC duct board materials and accessories that are necessary for insulating HVAC ductwork with insulation board including the fiberglass or mineralwool duct board, pins and fasteners, aluminum cladding, and tapes.
  • Duct Wrap Insulation: Fiberglass Ductwrap is a thermal and acoustical insulation for wrapping commercial and residential interior HVAC ductwork.
  • Weather Protection / Cladding: Aluminum Cladding membranes and tapes protect exterior HVAC insulation from UV and weather.
  • Pins / Fasteners: All of the fasteners and tools needed for installing HVAC Insulation both duct board and duct wrap.
