The most effective noise control barriers combine the properties of both blocking and absorption. Barrier Backed Composites feature a reinforced loaded vinyl noise barrier with a quilted fiberglass sound absorber on one side for maximum noise reduction. 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 enhanced its acoustical performance. BBC Composites are available in bound or unbound rolls as well as custom fabricated panels and die cut pieces making it an extremely versatile sound control product.
