The Stywall acoustic wall isolation strip or bearing stops flanking noise such as impact sound and airborne sound transmission to the floor slab and side walls, improving the airborne noise insulation of the walls and the impact noise insulation under the floor.
Impact noise as well as airborne noise propagate themselves through the structures of the building in the form of vibration and after will transform themselves into re-irradiated noise in the rooms nearest to the noise source. This is sometimes known as flanking noise transmission. An efficient solution to block this transmission of vibration noise is to separate any structural wall with anti-vibration elements. This is the case with partition walls and any separating wall which can be disconnected from the base and neighboring walls with a Stywall acoustic wall isolation strip underneath the wall.
