Fiberglass DUCT Wrap Insulation
- Material:Fiberglass
- Color:Yellow
Hot air escaping through ducts, cold spots in rooms, energy bills that keep climbing. Leaky ductwork wastes up to 30% of your heating and cooling costs every month. This yellow fiberglass duct wrap with foil facing seals around rectangular and round ducts to keep conditioned air where it belongs.
We stock this duct wrap insulation year-round and install it within days of your call. No waiting weeks for special orders, no surprise charges when we arrive. You get quieter HVAC operation and lower monthly bills.
This duct wrap insulation is designed for commercial, industrial, and residential HVAC systems. The yellow fiberglass core provides thermal resistance while the foil facing acts as a vapor barrier and reflects radiant heat.
Common applications include wrapping supply and return ducts in unconditioned spaces like attics, basements, and crawl spaces. Also used around mechanical equipment and piping that requires thermal protection. The flexible roll format makes it easy to wrap around curved surfaces and irregular shapes.
Each roll comes ready to install with the foil facing intact. You will need separate tape or mastic to seal seams and joints. The material can be cut with a utility knife for custom fitting.
This insulation is not suitable for direct contact with hot surfaces above standard HVAC temperatures. Regular inspection is recommended to ensure the foil facing remains intact and properly sealed.
