Sound barrier - SX-N

Hig density mineral wool has good sound deadening properties and can be encased in either high specification pre-galvanised and painted steel or aluminium panels to produce a light weight sound absorbing barrier. These are used extensively throughout urban areas and on structures.

Each panel is made of corrosion-resistant aluminium steel, and perforated for acoustical absorption.

The size and pattern of the perforations are designed to protect and maintain the sound-absorptive capability of the acoustic fill inside the panels. The reverse side away from the road, is made to non-perforted galvaised steel, also corrosion-resistant.

Metal structures cut the build up of reverberant sound between parallel barriers and resulting in noise reduction higher than that providedby the hard -surface alternate.

A unique design feature of the aluminium and steel barrier construction is that steel barrier construction is that individual panels can be removed and replaced. Panels are not bolted, welded, or otherwise permanently fastened to each other or to the support posts.

Should replacement be called for as a result of structural damage, no more than three workman using ordinary hand tools will be able to do the job.
