SORBERFLEX® ALR

SORBERFLEX® ALR is a composite sandwich material comprising of a flexible high mass noise barrier, based on Wavebar® technology, laminated between two layers of flexible acoustic foam with a top-side facing of reinforced aluminium.

Both the decoupling foam and ALR faced absorptive layer are composed of Pyrotek’s SORBERFOAM® combustion modified, polyether polyurethane foam that provides excellent hydrolysis resistance. This foam is especially suited for use in wet and humid areas, such as boats or tropical environments.
