Duct insulation wraps HVAC ductwork with thermal material to reduce heat loss or gain as air travels through the system. It improves efficiency, lowers utility bills, and helps prevent condensation that can lead to mold or duct damage.

Duct insulation wraps HVAC ductwork with thermal material to reduce heat loss or gain as air travels through the system. It improves efficiency, lowers utility bills, and helps prevent condensation that can lead to mold or duct damage.
Why is duct insulation important?
It keeps conditioned air at the right temperature and reduces energy loss as air moves through the ducts.

Higher R‑values reduce heat loss and improve efficiency.
In an attic with unconditioned air, insulating ducts keeps cooled air cold and heated air warm, improving comfort throughout the home.
Seal duct leaks before adding insulation for the best efficiency gains.
“Seal duct leaks before adding insulation for the best efficiency gains.”
The DOE recommends insulating ducts in unconditioned spaces to at least R‑6 in many climates.
What R‑value do I need for duct insulation?
Most climates benefit from R‑6 or higher in unconditioned spaces, but local codes vary.
Can I insulate ducts without sealing them?
You can, but sealing leaks first delivers much better efficiency gains.
Does duct insulation reduce noise?
Yes. It can dampen sound transmission and reduce duct noise.
