Megasorber BR

Flexible Reinforced Noise Barrier

Features

flexible reinforced noise barrier

Megasorber BR is a flexible high-performance sound barrier. It is a low stiffness material which improves the sound transmission loss by effectively blocking noise.

Megasorber BR is a high temperature resistant noise barrier. It provides an excellent soundproofing effect at a wide range of temperatures, typically from -40°C to +130°C, where other traditional noise barriers would fail.

Megasorber BR has a reinforced backing to further enhance its mechanical strength. It is designed for hanging applications where the material is typically used as an acoustic curtain.
