Quiet Liner™
Quiet Natural Fiber Liner (Patent Pending) is a thermally bonded HVAC 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.
Features and Benefits:
Excellent Noise Absorption
Recycled Cotton – “Green” Material
Class A Fire Rated
Reduces Heat Loss/Gain
