Key Features
- Fills cavities between layers to avoid cavity resonance and improve sound insulation (mass–spring principle)
- Reduces structure-borne noise from walking, banging and furniture movement in floating floors
- Example: brick wall 170 mm with plaster Rw 53 dB → Rw 62 dB with ReBond 40 mm + 18 mm gypsum board
Applications
- Wall & partition cavities
- Floating floors
- Sound absorption
- Impact noise control
Technical Specifications
- Standards
- ISO 140-3 · ISO 717-1
