A high-density polyurethane sound absorber designed to isolate low-frequency sound transmission through walls, ceilings and floors. Manufactured by MMTPL at the Palwal plant, Haryana.
Applications
Where BassBloc® goes
Cavity walls in residences
Ideal for use within cavity walls to isolate sound between adjoining dwellings, flats and individual rooms in residential buildings, ensuring privacy and reducing noise transmission.
Commercial spaces
Installed in the cavities of external walls and suspended ceilings, BassBloc® blocks low to high-frequency noise in commercial settings with moderate sound levels, such as bars, restaurants and supermarkets.
Shared living spaces
Used to renew and enhance sound isolation in walls separating different living units within residential buildings, for improved noise control in shared living environments.
Also used in
- Industrial noise separationActs as a barrier between office spaces and production areas within industrial buildings, reducing noise transfer for a more comfortable and productive work environment.
- Home theatresInside walls and ceilings behind the finish.
- Recording studiosLow-frequency control in isolated rooms.
- HotelsGuest room and corridor partitions.
- OfficesMeeting room and cabin partitions.

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®This product
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.
