Test campaign: Stravifloor & Stravilink on CLT

Learn more about how CLT-assemblies can provide satisfactory sound insulation by using acoustically decouple suspended ceilings and lightweight floating floors

CDM Stravitec conducted a second test campaign to measure the sound insulation properties of dropped ceilings with Stravilink acoustic suspension hangers and lightweight Stravifloor floating floor systems in combination with CLT (cross-laminated timber). Main goals of this complementary study were:

  • Studying the impact of acoustical suspended ceiling with resilient hangers and insulation material in the void in comparison with non-acoustical suspended ceiling;
  • Identify the impact of an acoustic treatment strictly from below a bare CLT slab.
