Quiet Natural Fiber Liner (Patent Pending) is a thermally bonded HVAC acoustic insulation that offers superior acoustic and thermal performance. Made from natural fibers, Quiet Liner contains no fiberglass and does not itch or cause skin irritation. The fibers used to manufacture Quiet Liner offer excellent sound absorption properties. The air stream surface of Quiet Liner is overlaid with a durable, fire-resistant black facing providing additional strength to the product. Both the insulation and the facing are treated with an EPA registered anti-microbial agent.

Uses

Quiet Natural Fiber Liner is used primarily as an acoustic duct liner designed for HVAC sheet metal to absorb unwanted noise from multiple sources. Quiet Liner HVAC acoustic insulation also reduces heat gain or loss. Quiet Natural Fiber Acoustic Duct Liner contains no harmful irritants and is safe to handle and install.
