Sinton X3

For stair landings

The SINTON® X impact sound insulation element decouples landings in stairwells from the walls and thus from living and working areas in terms of impact sound. SINTON® X consists of a plastic box with integrated sound insulation bearings for load transfer. Depending on the design, positive and negative transverse forces as well as horizontal forces can be transferred.

SINTON® X has been tested in accordance with DIN 7396 and meets the requirements for increased sound insulation in accordance with DIN 4109-5. SINTON® X is suitable for use in both masonry and concrete walls. The stair landings can be constructed in in-situ concrete or as prefabricated elements.
