How to Install Heating Duct Insulation in Your Vista Home

How to Install Heating Duct Insulation in Your Vista HomeUninsulated HVAC heating ducts in attics, subfloors and basements regularly lose heat through the walls, consequently reducing the efficiency of your heating system. The best way to reverse this effect is to insulate all your ducts with non-conductive material.

Insulating your heating ducts restricts heat loss, increases your system’s energy efficiency and reduces overall operational costs. While some homeowners consult contractors for this task, you can handle it yourself. All you have to do to is:

  • Begin by carefully inspecting your entire HVAC system and ducts. Ensure they’re properly functioning before turning the heating unit off for about two hours to allow the ducts to cool.
  • Protect yourself with a duct mask, work gloves and safety glasses before accessing your ducts. Overhead and attic ducts should be safely accessed by a step ladder, while subfloor ones can be accessed through crawlspaces.
  • To comprehensively insulate all ducts, you need to obtain foil-face fiber glass insulation that’s sufficient enough to cover all surfaces. To do this, you need to first measure the surface area of all duct surfaces and ensure that the figures correspond to the insulation’s size.
  • Get some butyl, foil, or any other heat-approved tape, and wrap strips of it around all duct joints. An overcoat of duct sealer should then be applied with a paint-brush.
  • Place the foil-face insulation by taping it to individual ducts. To ease the process, use the tape to attach one end of the foil to the surface as you wrap it around the duct.
  • Overlap the two foil edges and pin or staple them together with 8D framing nails to ensure all duct surfaces are covered. Complete this procedure by taping over the seams with any heat approved tape.
