Louver type sound barrier noise barrier

Louver sound barrier: The noise barrier panel is perforated with a louver, the sound wave will sink into the hole when it hits the sound barrier. In the middle of the panel, there is a thick layer of absorbent cotton. The noise is not easy to get out from it . The absorbent cotton is coated with alkali-free water-repellent glass cloth.
This kind of louver design fully considers waterproof and dust-proof. Its angle is set at 45 degrees. Sound absorption is not affected in dusty or rainy environment . Drainage measures have been set up to avoid water accumulation inside the components. The noise barrier panel can be powder coated , with strong corrosion resistance and long service life.

Louver sound barrier Material:

Galvanized panel: The thickness of the plate is from 0.5mm to 1.2mm. The material is hard, it is not easy to be deformed, and the service life is 12-15 years. It is an important part of the sound insulation wall (sound barrier) and the best choice raw material for the sound barrier.
Aluminum panel: The thickness of the plate is from 0.7--1.2mm, the material is soft, and the most important is light. It is generally used on the bridge sound barrier to reduce the load on the bridge.
