Straviwood ModuBreak

Resilient pads for acoustic decoupling of CLT modules

The resilient pads, Straviwood ModuBreak, have been specially designed to acoustically decouple stacked modular building parts of CLT, minimizing flanking sound transmissions, improving the vibration and structural noise isolation thanks to a decrease of stiff contact between modules throughout the building.

Main Characteristics

  • Ideal for decoupling of CLT modular 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, 20 mm, and 25 mm
  • Can be designed to meet natural frequencies between 10 Hz and 25 Hz
  • Can be manufactured in a variety of dimensions to accommodate acoustic design loads up to 10 MPa
  • Lifespan greater than 50 years
  • Quick and easy to install
