Schöck Tronsole® type B with type D

Schöck Tronsole® type B can be used to provide acoustically insulated support where the base of an in-situ concrete or precast staircase rests on the floor slab (e.g. cellar stairs). Schöck Tronsole® type B separates stairs and floor slab across the entire surface, thus minimising the risk of acoustic bridges.

  • Schöck Elodur® elastomer support
    Ensures an impact sound level delta of ∆Lw* ≥ 27 dB to ∆Lw* ≥ 33 dB on all products, tested to DIN 7396.
  • Fire resistance class F90
    Joints connected with Tronsole® type F/B are classifiable as fire resistance class F90 under DIN 4102
  • Integrated strips
    Can be stuck onto precast elements to stop the product slipping when moving the stairs. For fast and efficient execution
  • 4 (V2)-5 (V1) standard lengths and 2 standard widths
    Can be easily cut to length to reduce waste
  • Suitable for emergency exits
    Confirmed in the fire safety certificate

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.

Schöck Elodur®

Schöck Elodur® is an elastomer support that was developed specifically for impact sound insulation. It is the key component in Schöck Tronsole®. Unlike conventional impact sound insulation supports, Schöck Tronsole® achieves an improvement of about 10 dB in impact sound insulation performance by using the elastomer support, Schöck Elodur®. This is approximately equivalent to about half the perceived loudness level.
