HALFEN Impact Sound Insulation Products

Sound transmission caused by footsteps on staircases can be an unpleasant experience. Whether it is your good nights sleep in a hotel, or your recovering in a hospital--insufficient impact sound insulation can cause discomfort to your rest or to your recovery.

HALFEN has engineered and designed a diverse range of sound insulation products which can be used individually or in combination with each other to provide maximum sound insulation.

HALFEN HBB bi-Trapez-Box is used as a point-load support for staircase landings. The load of the staircase is transferred into the building via a profiled elastomer support elements. The elastomer supports minimize the sound impact, i.e., individuals walking up and down the stairs. The HALFEN HBB product can be used for cast in-situ staircases or precast elements to connect them to concrete or masonry walls.

HALFEN HTF Impact Sound Insulation units have been engineered and developed to support pre-fabricated staircases on in-situ staircase landings.
The load transmission is achieved through an elastomer support. The landings are monolithically connected with the building. The impact sound insulation is installed between the landing and the staircase.

HALFEN HTT Impact Sound Insulation Units are engineered to connect precast or in-situ staircases to the staircase landings that are cast on site and carrying predominantly stationary loads. The HTT Elements are particularly well suited for transferring shear and horizontal loads.
