Noise protection along roads

Our highly-absorbing aluminium noise barriers are located where traffic noise has a lasting impact: on motorways, busy roads and bridges.
Thanks to their specialised design, they ensure that the environment and surrounding areas are protected from being exposed to excessive noise. We would be happy to advise you on your road construction project!
This is why noise protection on roads & motorways is important
The Federal Immission Protection Act (BImSchG) and the Traffic Noise Protection Ordinance (16. BlmSchV) set out regulations regarding noise protection. A distinction is made between two time zones (day & night) and four area categories (industrial area, core / village / mixed area, general residential area, hospital / school / health care home / old people's home).
Depending on the requirements, maximum decibels are set, which your road must not exceed. One suitable measure for reducing the sound level is noise protection barriers.
Area category |
Day |
Night |
---|---|---|
near hospitals, schools, health care centres and old people's homes | 57 dB | 47 dB |
in general residential areas and small settlement areas | 59 dB | 49 dB |
in urban centres, villages and mixed areas | 64 dB | 54 dB |
in commercial areas | 69 dB | 59 dB |
The effect of noise barriers along motorways

No noise protection

With noise protection
Noise protection barriers have a noise shielding effect. If they are placed near a source of noise, they prevent the propagation of the sound to the surrounding environment and residential areas. This enables noise reduction of up to 20 decibels.
The actual effectiveness of a noise barrier depends on various factors such as height, construction, source of noise and distance to it. Overall, noise barriers are a proven means of protecting surrounding areas from traffic noise.
Noise barriers made of aluminium and glass for roads
We manufacture our noise barriers from aluminium and optionally acrylic glass. You have full control over the design and can decide whether transparent noise protection elements provide a view of the surroundings or whether the street is completely shielded by noise protection cassettes.
In addition, we offer different design options so that the sound insulation fits into the environment in the best way possible. Thanks to our in-house production, we can always offer you the highest quality. We would be happy to assist you in choosing between aluminium frame systems with transparent materials and highly absorbing noise protection cassettes!
