Straviwood WallBreak-S

Resilient strip for acoustic decoupling of CLT walls

A resilient strip designed to improve the acoustic performance of CLT constructions by limiting flanking sound transmission through walls while maintaining continuous load transfer to the slab. Its resilient design reduces rigid connections between structural elements, helping to control vibration and structure-borne noise throughout the building.

Main Characteristics

  • Ideal for wall-floor decoupling in CLT constructions
  • Suited for all wood-based materials
    Straightforward installation, no additional tooling required
  • Wide range of material options for optimal performance across all load conditions
  • Ensures reliable long-term performance through low creep and reduced differential deflection
  • Standard thicknesses of 12.5 mm (1/2’’) (and 25 mm (1’’))
  • Widths adapted to the dimensions of the wall
  • Quick and easy to install
  • Easily customized to the required length for a perfect fit
  • Detailed installation plan available upon request
  • High friction surface (coefficient of friction >=0.5) minimizes the risk of slippage during installation and service life

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.
