Noise Protection – our passion!

Aluminium noise protection elements

Bongard & Lind - Aluminium noise protection systems are designed for use as structural noise protection systems along streets, railways, airports or other noise sources.

They are suitable for outdoor use and because they are very lightweight ideal for bridges, supporting structures, or as noise absorbing cladding on reflective surfaces.

Bongard & Lind – noise protection elements are manufactured depending on requirements in reflecting, single-sided or double-sided high-absorbing variants. The seawater-resistant aluminium alloy single element guarantees high corrosion resistance even in the absence of surface coating and thereby ensures long durability.

The aluminium elements can be laid as required, horizontally, vertically or in another installation shape. The cassette-form individual parts are connected by a simple connecting system without the need for rivets, brackets or bolts. A tongue and groove system ensures precise fitting and excellent noise protection. The internal sound-absorbing insulation mats are at an optimal distance from the exterior on the holed side, protecting them against the weather and dust.

Transparent noise protection elements

Transparent noise protection elements are required where views of the surrounding area are particularly important and where noise protection structures infringe on visual free space. Die Bongard & Lind GmbH & Co. KG manufactures and builds transparent noise protection walls. The benefits of light aluminium frame systems are used in combination with transparent materials.
