Noise Barrier For Highways and Railways

Metallic noise barriers are made of acoustic elements placed horizontally or vertically between the supports railings. They allow a large architectural flexibility (colors, motifs, structures…). Their lightness allows producing them quickly, which is economical.

These barriers are isolating and absorbent and meet the strictest criteria of the European standard EN 1793 regarding devices for the reduction of road traffic noise. Acoustic absorption according to EN 1793-1 & Acoustic isolation according to EN 1793-2.

Elements are made in aluminum or galvanized steel . They contain a mineral wool protected by a non defiberizing geotextile that will eventually be neoprened. A perforated grill in aluminum insures the mechanical protection of the absorbent material.

Metallic noise barrier which comprise the great majority of noise barriers are generally located at the edge of the road to reflect traffic noise. Some noise is transmitted through the barrier, but is slightly less intense than the noise level on the other side of the barrier. The height of these barriers is usually greater than other types. Often traffic noise levels increase for vehicle occupant
