Block Radiant Heat in Summer

Your AC’s chilled air glides through insulated ducts untouched, staying frosty even when the attic reaches extreme temperatures.

Retain Warm Air in Winter

During winter, insulated ducts prevent warm air from escaping and stop cold attic air from entering the system, keeping your home comfortable and energy-efficient.

Enhance HVAC System Performance

By improving thermal efficiency, Energy Shield duct insulation reduces HVAC run times 17–23%, quiets your system, extends its lifespan, and lowers energy costs. Stable duct temperatures mean improved airflow, reduced workload, and long-term savings.

Enhance HVAC System Performance with Ductwork Insulation

Energy Shield insulation helps maintain stable duct temperatures, reducing system strain and lowering energy bills. Over time, this translates into fewer repairs, less maintenance, and improved comfort for homes or commercial buildings.

Radiant Barrier Protection for Unconditioned Spaces

Uninsulated ducts in attics, basements, or crawl spaces waste energy and accumulate moisture. Energy Shield reflective insulation acts as a radiant barrier and vapor shield, reflecting up to 97% of radiant heat while preventing condensation and mold.

Installing basement insulation or crawl space insulation complements ductwork insulation, creating a fully insulated envelope that improves comfort and reduces energy bills.

Ductwork Insulation FAQs

How does ductwork insulation work?

Reflective insulation blocks radiant heat while the core reduces conductive heat transfer, keeping conditioned air at its intended temperature.

Is ductwork insulation worth it?

Yes. It reduces energy loss, improves comfort, and protects your HVAC investment

Can I install duct insulation myself?

Yes. Our products are lightweight and flexible, perfect for DIY installation.

Does it reduce HVAC energy bills?

Yes. Reflective insulation maintains temperatures inside ducts, lowering energy costs. Energy savings are further enhanced when ductwork insulation is paired with radiant floor insulation.

Does it help with noise, condensation, or mold?

Yes. It reduces condensation, minor noise, and prevents mold in unconditioned spaces.
