Straviwood WallBreak-S

Resilient strip for acoustic decoupling of CLT walls

The resilient strip, Straviwood WallBreak-S, has been specially designed to minimize the flanking sound transmissions via CLT walls when continuous load transfer on the slab is required. The overall vibration and structural noise isolation of CLT constructions is improved thanks to a decrease of stiff contact between the structural elements through the building.

Main Characteristics

  • Ideal for wall-floor decoupling in CLT constructions
  • Suited for all wood-based materials
  • No additional tooling required for correct installation
  • Material range with high load capacity, offering a wide range of workloads
  • Excellent long term behaviour (low creep / differential deflection)
  • Standard thicknesses of 12.5 mm (and 25 mm)
  • Widths cut to dimension of the wall
  • Quick and easy to install
  • Easy to cut
  • Available with different types of resilient material (CDM-10x (7 types) & CDM-90x (13 types))
  • Detailed installation plan available upon request
  • Can be glued (see installation manual for recommended glues)
  • Coefficient of friction ≥0.5

Case Studies

  • Paviljoen Pannenhoef Leemerhoef (exterior)

    Paviljoen Pannenhoef Leemerhoef

    The façade elements were acoustically decoupled using a polyurethane foam strip called Straviwood WallBreak-S to address the flanking transmission.

  • Brahmslaan Leiden

    Brahmslaan

    To counteract flanking transmission, the CLT roof floors are placed on Straviwood WallBreak-S polyurethane foam strips at Brahmslaan Leiden.
