HVAC Quiet-Duct Wrap Soundproofing

Made from durable natural fibers, Quiet-Duct Wrap™ contains no fiberglass and does not itch or cause skin irritation. The fibers used to manufacture the Quiet-Duct Wrap™ offer excellent sound absorption properties and every fiber used is individually treated with an EPA registered anti-microbial agent that offers excellent protection from mold, mildew, fungi, and pests as well as fire resistance.

The Quiet-Duct Wrap™ has a pure aluminum barrier that reflects unwanted radiant heat and offers excellent protection from air currents, moisture, and vapors.
