Noise protection can look this good

Noise harms health and can cause a range of complaints

Purpose-built walls provide effective protection against noise, and today they no longer have to be made of concrete or be an eyesore.

RAU.bayern stands for densely planted noise barriers. What all our models have in common: they are living structures that blend into their surroundings while effectively keeping noise out.

RAU noise barriers also need very little care and maintenance. That is what the suffix "Extensiv" after the model name stands for, as opposed to high-maintenance "intensive" planting.

The planting is done at the foot of the wall, so the climbers growing up it always have enough water. A RAU noise barrier therefore makes use of natural rainfall and needs no irrigation.

If required, we can add a further planted layer along the top of the wall, which likewise needs no irrigation. We mainly fill the RAU Klimawand with processed recycled crushed stone, for which the supplier provides a certificate; in some regions gravel or crushed stone from gravel pits is used. Best of all is suitable material from the construction site itself: the excavated soil then needs no disposal, and no fill has to be bought and delivered. This fill keeps its volume and is highly durable, giving the wall a long service life. RAU Rock is built differently and has no fill: a sound-insulating fibre-cement panel with water-repellent stone wool does the work.
