Pakon Sound board NL (stair string)

The Sound board NL is used to create the joint between stairs resp. landings and the staircase walls without acoustic bridges. All concrete elements can be made of in-situ concrete or as prefabricated parts. The boards made of PE foam are self-adhesive with no load-bearing function. An adaptation of the Sound board NL to different geometric shapes of the concrete elements is possible by cutting on-site.
