BlokAll® - Noise Barrier Composites
Noise Control Specialist offers two types of Noise Barrier Composites, the Barrier Backed Composite (BBC) and the Barrier Septum Composite (BSC)
The BBC model Barrier Backed Composite in constructed with a reinforced loaded vinyl noise barrier with a quilted fiberglass absorber on one side. The heavy-duty 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 broaden its acoustical performance.
The BSC model Barrier Septum Composite has a non-reinforced loaded vinyl noise barrier septum (middle) with a quilted fiberglass sound absorber on both sides. It performs best as an acoustical liner. The inner layer of quilted fiberglass decouples the barrier from the surface to which will improve its noise blocking capability while the outer layer adds sound absorption to the treated environment.
