AlphaSorb® Composite Foam combines a mass loaded sound barrier with layers of absorptive acoustic foam to double up on sound control. This composite foam combines a the one pound per square foot sound barrier between two layers of acoustical foam. Together, these layers both absorb, block and isolate mid to high frequency noise. This reduces the overall transmission of sound when constructing sound enclosures or partitions.
The thicker, one inch foam should face towards the source of the noise to absorb sound within the space. Then the barrier layer provides a sound blocking layer to lower sound transmission through the panel. Finally, the thinner melamine foam layer provides an airspace to decouple the panel from the surface to which it is mounted. Our composite foam is fiber-free, so you’ll have no handling issues. They are also easy to cut to any size and install. For further ease of installation, we offer a peel and stick (PSA) option. Just make the necessary field cuts, peel off the backing and stick the sheets to the substrate. Composite foam is the perfect choice for lining enclosures to reduce machine noise. To lower create an effective soundproof enclosure, all surfaces of the system, partition, box, wall or enclosure should be covered seamlessly.
