The problem it solves
What acoustic cellulose spray fixes for you
Echo under hard concrete ceilings
Sound absorbs into the sprayed layer instead of bouncing off the slab.
Ceilings where panels will not fit
Curves, domes and irregular shapes get a seamless acoustic finish.
Loud restaurants and retail floors
Reverberation drops, so conversation and music stay clear.
Offices and classrooms with poor speech clarity
25 mm and above gives maximum absorption in the speech frequencies.
Designs that cannot show grids or joints
A continuous, jointless surface in the colour of your choice.

Soundproofing: the fix for every sound problem
3-layer soundproofing
- 1
Layer 1: SoundBlanket® MLV
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.
