Polycarbonate Noise Barrier

Constituents :-

The polycarbonate noise barrier comprises of a metallic frames made of steel or aluminium. The supporting frame is galvanised to ensure that it is protected against weather. The noise barrier sheets are made either of polycarbonate material or acrylic sheets. These sheets are fitted into the groves of the metallic frame to ensure a perfect fit. To warrant a total noise protection the grooves are lined with rubber to prevent the leakage of sound.

Salient Features of Enviro Polycarbonate / Acrylic Sheet Noise barrier:-

The polycarbonate / acrylic noise barriers are designed to be eco-friendly. It provides the required acoustic attenuation and is built to sustain in an outdoor environment. Outdoor properties: The noise barrier structure can withstand high velocity wind and air pressure changes. The structure is firmly fixed and will not give way in adverse weather conditions. Safety: The noise barriers are totally safe from every aspect. The possibility of a mishap from the barrier structure is eliminated. The barriers are made from safe materials that are non-harmful to the atmosphere. Noise blockage: The barriers are designed in a manner to provide a substantial noise blockage. The height of the barrier is calculated as per the sound attenuation requirement which takes into consideration the height of the source as well as the height of the area that needs noise protection. Low maintenance: The noise barrier structure has been designed in manner that calls for little or no regular maintenance. The polycarbonate / acrylic sheets are maintenance free materials with a plain surface that does not allow dirt particles to settle on its smooth surface. If required the surface is easy to clean. The noise barrier provides effective sound absorption and very little transmission loss. The gasket seals at the joints ensure that there is no sound leakage. The standards noise reduction level is 36 dB(A).
