Impact sound insulation element for connecting staircases to landings with a straight joint

Schöck Tronsole® type T

Schöck Tronsole® type T can be used for acoustically insulated connections between in-situ concrete or prefabricated stairs and in-situ concrete or element landings. The range covers all landing thicknesses and stair widths. Connections do not require corbels. For sophisticated architectural designs.

  • 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 R90
    Complies with the requirements for fire resistance class R90 (subject to appropriate on-site additional reinforcement of the landing)
  • Suitable for emergency exits
    Confirmed in the fire safety certificate
  • Straight joint profile
    Enables straight joints and easy removal of formwork at the prefabricating plant or on site
  • Customised
    Type T can either be cut to length or ordered in the required length. Minimum lengths apply.
  • Integrated gripper
    For easy fastening to the formwork

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®: elastomer support developed for impact sound insulation

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.
