Straviwood WallBreak-P

Resilient pad for acoustic decoupling of CLT walls

A resilient pad designed to improve the acoustic performance of CLT constructions by limiting flanking sound transmission through walls when discontinuous load transfer to the slab is permitted. By minimising rigid connections and contact areas between structural elements, it helps control vibration and structure-borne noise.

Main Characteristics

  • Ideal for wall-floor decoupling in CLT constructions
  • Suited for all wood-based materials
  • Straightforward installation, no additional tooling required
  • Can be glued in the factory or installed on site, helping to streamline construction workflows
  • 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 20 mm
  • Widths adapted to dimension of the wall
  • Discrete pad design minimizes contact area between structural elements, reducing flanking sound transmission paths
  • Detailed installation plan available upon request
  • High friction surface (coefficient of friction >=0.5) minimises the risk of slippage during installation and service life
  • Optional: Mineral wool infill helps reduce airborne sound transmission through the gap while maintaining acoustic decoupling
