Straviwood WallBracket

Acoustic angle bracket for structural joints in CLT construction

An acoustically isolated angle bracket engineered for structural joints between perpendicular building elements, such as walls and slabs. It integrates resilient pads that minimise flanking sound transmission while maintaining the required structural performance for shear and vertical load transfer. Ideal for CLT and other timber construction systems, it combines acoustic efficiency with structural integrity.

Main Characteristics

  • Delivers superior acoustic comfort compared to rigid wall-to-floor connections by significantly reducing flanking sound transmission while providing the required lateral support
  • Complements Straviwood WallBreak-P and Straviwood WallBreak-S to create a fully decoupled CLT wall connection system
  • Compatible with different timber-based construction materials, providing flexibility across a wide range of projects
  • Designed for quick and error-free installation, with an integrated stop that automatically achieves the correct compression level without measurements or adjustments
  • Enables fast and straightforward installation without the need for specialised tools or adjustment procedures
  • Provides long-term durability and corrosion resistance thanks to its galvanised steel construction

The total vibration reduction index, Kij, can be calculated using norm ISO 12354-1 and expresses the attenuation of the vibrational power flow through a junction, playing a key role in transmission. However, the formulas suggested by this standard are only applicable to rigid connections where metal connectors or elastic decoupling materials are not being used. Significant differences have been noticed between the calculations based on the norm versus measured Kij values in situ.
