HTF Impact Sound Insulation
HTF Trittschalldämmelement
HALFEN HTF Impact Sound Insulation units have been developed for supporting prefabricated staircases on in-situ prepared bearings of staircase landings. The load transmission is done via elastomer bearings. The landings are monolithically connected with the building in this case. The impact sound insulation is implemented between landing and staircase.

Quality features are
  • - Excellent sound insulating properties in a wide range of bearing pressures
  • - General constructional authority approval for the bearings
  • - For staircases from 100 to 120 cm width, broadness adaptable arbitrarily through insulation and landing strip
