Noise Barrier

Noise Barrier is an outdoor acoustic fence system for highways, railways, residential boundaries, factories, bridges and construction perimeters. It consists of perforated metal acoustic panels, internal sound‑absorbing material and steel H‑posts. The perforated side faces the noise source; the solid back sheet blocks airborne sound. Common panel thicknesses are 80 mm, 100 mm and 120 mm. Standard panel modules are 500 mm high, in lengths of 2000 mm or 2500 mm. Typical overall barrier heights range from 2 m to 5 m, designed according to site layout, noise source height and project requirements.
