Combined road equipment:
 crash barrier and noise screen in one solution

​​As a starting point, guard rails and noise reduction are installed as separate solutions, as they are two different functions that must be fulfilled. In some cases, however, this is not an option due to a lack of space or a desire for an integrated solution.

​DAV NORDIC therefore offers a product that meets this need. It is a solution where the noise screen is mounted directly behind the crash barrier. The obvious advantage is that you save space. Another advantage is that the closer the noise dampening solution is to the noise source, the more noise it picks up.

One of DAV NORDIC's noise reduction solutions is noise barriers. The noise barrier is a noise-absorbing crash barrier system that consists of a crash barrier and noise reduction in one system. It has the same height as other crash barrier systems, and significantly reduces noise. Of all traffic noise on roads, 80% comes from tire noise. With a short sound source, if the guard is close to the sound source, there is no need for a tall screen to attenuate the noise.

DAV NORDIC is a dealer of this crash barrier, which in addition to making traffic safer, must also help to reduce the noise from traffic. The crash barrier has the advantage that it is close to the noise source and that it is efficient and inexpensive to install. The advantage of attenuating the noise at the crash barrier is that the closer to the source the noise is blocked, the more effective the noise attenuation is. If the noise screen is set up further away from the roadway, the noise will often go across the screen.

As the crash barrier is perforated, the noise will pass through the crash barrier and be absorbed by the noise wall behind instead of being reflected. The system has been crash-tested in accordance with current EU standard EN 1317 and is suitable for solutions in many municipalities, where the noise barrier can often be placed close to the noise source.

We are happy to provide technical advice in connection with our noise barrier and are available for a chat. Of course, we are also happy to make a non-binding offer on a specific case. Call us on +45 86 82 29 00 or write to us at info@davnordic.dk.


​REBLOC - Combined traffic guard and noise screen

​Many possibilities for combinations

Noise occupies more and more space in the soundscape today, and this also means that noise-reducing solutions have become more relevant.

In general, designing and installing a noise screen is a project that requires time and space, but in some situations it is not an option. This is where REBLOC comes into the picture. With this solution, you can get both noise reduction and traffic safety in one installation. This also means that here you get two solutions, which normally require a lot of space, in one solution that does not require very much space. REBLOC's system is also not mounted on buried foundations, which makes them obvious to use in many situations where you cannot simply dig foundations.

​REBLOC's solutions can be combined in many different ways, both in height and width, and can function as both a temporary and a permanent solution. This means that you can save both assembly time and money by choosing one of these solutions.

The combined guardrail and noise shield solution is available in many different solutions, and product browsing can be found below.
