PMMA Sound Wall Barrier

Noise induced hearing loss can happen due to continuous exposure to loud sounds over an extended period of time. Long or repeated exposure to sounds at or above 85 dBA can cause hearing loss. Residential and office buildings that are close to railway lines and highways need to include protection from damaging noise levels to protect public health. Politem’s PTEROFLAT XT branded acrylic acoustic wall barrier sheets which are specially designed to absorb and reduce sound, provides solution to manage high noise levels in urban and industrial areas that are close to railway lines or highways.

Thanks to it’s light weight and virtually unbreakable structure, PTEROFLAT XT acrylic (PMMA) sheets can be installed next to highways and railways conveniently without need of any maintenance for years.
