Barrier and Quilted
Fiberglass Absorber Composities
|
dB Engineering BSC
Composite features a non-reinforced loaded vinyl noise barrier septum
(middle) with a quilted fiberglass sound absorber on both sides.
Ideally suited as an acoustical liner, the inner layer of quilted fiberglass decouples the
barrier from the surface to improve its noise blocking ability while the outer layer adds
sound absorption to the treated environment.

dB Engineering BBC composite features a reinforced
loaded vinyl noise barrier with a quilted fiberglass sound absorber on one
side. The rugged durable exterior barrier is commonly used as a wrap or acoustical
jacket due to its ability to conform to any shape. The quilted fiberglass layer
decouples the noise barrier to enhance its acoustical performance.
