The Isocheck Universal Acoustic Angled Flanking Band is specially designed to act as a sound barrier between the floating layers and the surrounding structural elements, including door linings, walls, services and other structural elements. Flanking noise transmission is a common occurrence in floating floor systems and must be eliminated otherwise you are risking serious problems with acoustic bridging and noise leakage. By using the Isocheck Flanking Band means dealing with expansions are dealt with, leaving no room for air gaps and noise leakage. .
