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.
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 with a Stywall strip underneath the wall.
The Stywall strip stops impact sound and airborne sound transmission to the floor slab, improving the airborne noise insulation of the walls and the impact noise insulation with the under stair floor.
