PerMAP Metal Noise Barrier Panels

Designed as a highly absorptive noise barrier panels which is lightweight yet able to provide superior sound insulation, PerMAP panels have been used extensively as transportation noise barriers on elevated expressways, LRT/MRT rail links where loading on parapet walls is a major concern.  It is also ideal for use as noise barriers for compressors, cooling towers and other industrial noise control purpose.  

The prefabricated modular post-and-panel system allows for speedy and trouble-free installation at site.  The noise barrier system is also complete with safety features such as anti-glare coating and anti-fall containment to prevent secondary accident upon vehicular impact.
