Quiet Liner™ – Advanced Acoustic and Thermal Duct Insulation
Designed for performance. Engineered for comfort


Quiet Liner™ is a high-performance, natural fiber acoustic liner developed specifically for HVAC duct systems. Crafted from recycled cotton fibers, this fiberglass-free insulation delivers exceptional sound absorption and thermal control—ideal for projects prioritizing occupant comfort, environmental health, and sustainability.

Quiet Liner™ features a durable, black, fire-resistant scrim facing on the air stream surface, enhancing product strength and integrity. Both the liner and facing are treated with an EPA-registered antimicrobial agent to resist microbial growth and ensure long-term system hygiene.

Key Benefits:

  • Superior Noise Reduction – Excellent sound absorption across a broad frequency range

  • Thermal Efficiency – Minimizes heat loss and gain, improving HVAC performance

  • Class A Fire Rated – Meets critical fire safety standards for commercial installations

  • Healthy Indoor Air Quality – Free of formaldehyde and fiberglass; no itch or skin irritation

  • Low Air Resistance – Maintains airflow and system efficiency

  • Antimicrobial Protection – Helps prevent mold, mildew, and bacteria buildup

Quiet Liner™ is the choice for professionals who demand performance without compromise—perfect for noise-sensitive environments like offices, schools, healthcare facilities, and mixed-use developments.
