Wall Decoupler.
 
The dBA WD is a anti-vibration wall decoupler. It is used to fix a wall structure to a previously existing wall, preventing the creation of acoustic bridges between the two of them. The Brick versions have a single fixing point which provides the needed stability together with a fast, very simple and less invasive installation. The Wood versions come with two fixing points which grant a stable connection, even in hostile surface structures. The WD series provide solutions for different wall constructions, gap dimensions and fixation requirements.
