Straviwood WallBreak-P

Resilient pad for acoustic decoupling of CLT walls

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

Main Characteristics

  • Minimizes the contact surface (less material needed)
  • 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 20 mm (other thicknesses available upon request)
  • Detailed installation plan available upon request
  • Coefficient of friction ≥0.5
  • Can be glued to the CLT wall either on site or in our factory
  • Available as loose pads or glued to HPL (clustered)
  • Optional: the gap between the pads can be filled with light dense mineral wool (on site or in factory)
  • Quick and easy to install
