Noise is unwanted sound. Highway traffic noise tends to be a dominant noise source in our urban and rural environment. There are three sources of traffic noise, depending on the origin: vehicle engines, tyres and aerodynamics.

A sound barrier is an exterior structure designed to protect sensitive land users from noise pollution. Sound barriers are the most effective method of reducing traffic and industrial noise sources.

Knauf Insulation rock mineral wool insulation forms an integral part of the road sound barrier. With its outstanding properties, especially with superb acoustic performance, it absorbs noise and provides noise insulation to protect people and the environment.

It is particularly suitable as core element for sound barrier systems on roads, highways (incl. high-speed rails) and other important applications. 

We provide customized solutions for:

    • Road sound barriers made of metal
    • Road sound barriers made of wood
    • Other systems for sound barriers, which need sound absorption core element
