Soundproofing: the fix for every sound problem

3-layer soundproofing

  1. 1

    Layer 1: SoundBlanket® MLV

    The dense barrier that isolates sound and stops it passing through walls, ceilings and floors.

  2. 2

    Layer 2: BassBloc®

    High-density sound absorber over the MLV that controls low-frequency noise.

  3. 3

    Layer 3: Echsorbix®, SoundaXe® or WDWL®This product

    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.
