SIDERISE BM/P Series Barrier Mat (formerly Lamaphon BM-PX)

A thin, bitumen free polymeric sound barrier offering exceptional flexibility. Combines a high surface mass with ‘limp’ mechanical characteristics, the product offers optimum sound reduction and dampening performance. Primarily designed to improve the sound insulation value of existing panels of metal, wood, plastic, GRP etc. It is particularly effective in reducing the effect of coincidence dip resonance found in these stiff, lightweight materials.

Additionally the product may be used in sandwich constructions between board materials or as an internal membrane in built up composites where final flexibility is required. BM/P Series Barrier Mat is clean and simple to use and can be readily cut to size with a sharp knife.
