Soundproofing: the fix for every sound problem
3-layer soundproofing
- 1
Layer 1: SoundBlanket® MLVThis product
The dense barrier that isolates sound and stops it passing through walls, ceilings and floors.
- 2
Layer 2: BassBloc®
High-density sound absorber over the MLV that controls low-frequency noise.
- 3
Layer 3: Echsorbix®, SoundaXe® or WDWL®
The final acoustic finish: Echsorbix® PET felt, SoundaXe® wooden acoustics or WDWL® wood wool panels.
Layer 2 can also be covered with gypsum or cement board before adding the final acoustic layer.
Different thickness in each layer will give different STC and NRC levels.
