Schöck Tronsole® type L: For insulating impact sound at the joint between stairs and wall

Schöck Tronsole® type L

Load-bearing Schöck Tronsole® types can be upgraded to surrounding soundproof systems using Schöck Tronsole® type L. Sound insulation measures can only be effective if all joints between staircase wall and staircase (steps and landing) remain free from soiling. All sound insulation performance figures for Schöck Tronsole® types relate to systems incorporating type L in the joint areas. Alternatively, a sufficiently wide architectural air joint is also possible. It must, however, be wide enough to prevent acoustic bridges forming when dirt drops through.

Impact sound insulation compared.

For the first time, DIN 7396 describes clear test conditions for measuring the acoustic properties of impact soundproofing elements. Tests are performed on common staircase geometries and under the loads usually occurring in buildings. The characteristic values specified in DIN 7396 can be used for soundproofing certification according to DIN 4109. All Schöck Tronsole® types have been tested using this procedure.
