Spray Foam • The Ultimate Rigid Ductwork Insulation
Closed-cell spray polyurethane foam is the ultimate insulation for your rigid [metal] HVAC ductwork. No other insulation option offers the advanced performance that spray foam insulation delivers. In one product application, your HVAC ductwork is air-sealed and insulated.
Spray foam is the logical choice if you have metal/rigid HVAC ductwork in your attic or under your raised home. It offers complete air sealing and superior insulation, which will help lower your cooling and heating bills and improve your indoor air quality.

Frequently Asked Questions
Insulating rigid/metal ductwork with closed-cell spray polyurethane foam insulation achieves two goals in a single application. First, it provides seamless insulation that will not sag or allow condensation to build up between the rigid ductwork and insulation. Second, it makes your ductwork airtight, eliminating air leakage and infiltration.
Yes! Leaky HVAC ductwork can increase your cooling and heating bill by up to thirty percent or more. Properly sealing and insulating your ductwork is one of the highest-payback energy efficiency improvements you can do. Plus, properly sealing your HVAC ductwork will significantly improve your indoor air quality.
Not when you consider all of the benefits of insulating your HVAC ductwork with spray polyurethane insulation. In one application of closed-cell spray polyurethane foam, your ductwork is air-sealed and insulated.
If you want to go the traditional route of insulating with fiberglass wraps, you first need to ensure that every seam and every connection is properly sealed with mastic and fiber tape so your ductwork is air-tight. Then, you need to wrap the ductwork with fiberglass and ensure that there aren’t any gaps or sags where condensation can build up.
Absolutely! When you insulate the ductwork under a raised house with closed-cell spray polyurethane foam insulation you get all the benefits of a single product application that air-seals and insulates, but you’re also not providing a potential nesting area in fiberglass wrap insulation for rodents and bugs.
