QFA Absorptive Exterior Grade Acoustic Curtains
QFA-2″ Quilted Fiberglass Absorbers
Exterior Grade Quilted Fiberglass Absorbers reduce the reflection of sound waves by covering reflective surfaces with a suitably UV-protected, porous, sound-absorbing product. The exterior Quilted Fiberglass Absorber consists of a heavy-duty vinyl-coated polyester facing on both sides of a 1” or 2″ thick quilted fiberglass. The outdoor sound barrier curtains are constructed with grommets across the top and bottom and are sewn with an exterior grade thread.
