The Industrial QFA -4 Rolls consist of a 1″ quilted fiberglass
absorber with a vinyl facing on both sides, and are used to reduce the reflection of sound waves or reverberant
noise energy within a piece of equipment, a room, or a building. All products
have a Class A flammability rating (per ASTM E-84 ).
Quilted Fiberglass Absorbers are fire safe, high performance acoustical fiberglass
blankets that are used to reduce reverberant (reflected) airborne noise energy
in many diverse industrial and architectural applications as well as on original
equipment. They are an excellent alternative to urethane foams since they are
fire safe, exhibit low smoke emissions and possess high mechanical strength.
Additionally, they have a wide range of temperature limits, can be cleaned,
and are unaffected by moisture, humidity, dust, dirt, oils and most chemicals.
Flexible quilted absorbers are easily installed, will not degrade, and have
extremely long service lives.
