Staircases have to comply with special building law requirements for sound insulation. With the impact sound insulation elements from H-BAU Technik, you can decouple stair landings and flights from living and working areas in terms of impact sound - for more peace and quiet and living comfort. Our insulation elements are also available with reinforcement cages. They are suitable for both in-situ concrete and prefabricated construction. In functional staircase systems, for example in multi-storey car parks, JORDAHL mounting rails can be used, for example, to place new treads and risers on the remaining steps, to attach pluggable railings or to fix signage.
