With the aid of the TSB impact noise insulation boxes, the noise generated in staircases (particularly in blocks of flats) can be isolated so that it is not transferred to the insides of flats or living areas. The TSB impact noise insulation boxes can be installed both in masonry and in concrete walls.

Pre-cast landings with supports in the form of integrated TSB impact noise insulation boxes are easy to install and prevent the formation of impact noise bridges. The different types are capable of absorbing positive, negative and horizontal shear forces.
