Echo Eliminator

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

  • No Formaldehyde

  • Resists Microbial Growth

  • Low Air Resistance

  • No Itch or Skin Irritation

  • LEED™ (more information)

Color:

Blue

Applications:

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