WHIS®top
The WHIS®top provides an additional noise reduction of 4–5 dB on top of the reduction offered by (existing) noise barriers. This improvement is comparable to increasing the height of a barrier by 2 meters, without the need for major structural modifications. By adding the WHIS®top, you can significantly enhance the acoustic performance of your existing noise screens, helping to create a quieter environment for nearby residents and road users. Its modular design allows for easy installation and integration with current infrastructure, making it a cost-effective and efficient solution for noise mitigation.
