high performance barrier-absorber composite

Sorberbarrier is a unique composite noise control product that offers both excellent noise transmission loss and high noise absorption. It was developed to meet market requirements for reducing noise in industrial and domestic enclosure, OEM and marine markets.

Sorberbarrier combines the superior performance of the flexible mass barrier, Wavebar® together with the high absorption properties of Sorberfoam™. Wavebar is laminated to the Sorberfoam layer to alter the natural absorption curve enhancing sound absorption in mid to high frequencies.

Sorberfoam is applied by using a sophisticated process that optimises flow resistivity and maximises sound absorption. With a black finish and a more discreet look.

The high performance of Sorberbarrier is achieved by its unique construction. Placing the mass barrier between two layers of absorbing foam, keeps the barrier separate from the structure to which it is bonded, allowing it to remain flexible at all times. This increases the noise transmission loss.

Tests have revealed that altering the thickness of foam that separates the noise barrier from the structure, improves the product’s performance in some frequencies without an increase in overall weight.

Sorberbarrier targets specific frequency ranges. The combination, makes it the most versatile product for controlling noise in the market place.
