01 / The product

BassBloc ® Sound Absorber

Roll Size: 6X3 Feet

Thickness: 20mm, 40mm

Key Solution: Provides sound absorption for low to high frequencies.

  • Applications

    Cavity Wall Solutions for Residential Sound Separation: 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. Performs best with the combination of SoundBlanket.

    Acoustic Insulation in Commercial Spaces: Installed in the cavities of external walls and suspended ceilings, BassBloc effectively blocks low to high-frequency noise in commercial settings with moderate sound levels, such as bars, restaurants, and supermarkets.

    Soundproofing Between Shared Living Spaces: Used to renew and enhance sound isolation in walls separating different living units within residential buildings, providing improved noise control in shared living environments.

    Industrial Noise Separation: Acts as a barrier between office spaces and production areas within industrial buildings, reducing noise transfer for a more comfortable and productive work environment.

Frequently Asked Questions

Who manufactures BassBloc Sound Absorber in India?

MMTPL (Mahabir Multi Tech Private Limited) manufactures it at its Palwal plant in Haryana, India, and supplies studios, offices, cinemas and industrial sites in India and 25+ export markets.

What is the NRC of BassBloc Sound Absorber?

BassBloc Sound Absorber has an NRC of 0.85, measured to ASTM C423. NRC is a single-figure average, so match the thickness to the frequency you need to control: thicker foam works lower down the spectrum.

What density is the foam?

The foam is high-density open-cell polyurethane at 32 to 50 kg/m3, which is what gives it absorption at mid and high frequencies rather than just at the top end.

Can BassBloc be left exposed?

No. BassBloc is a barrier layer at 100 kg/m3 and must be fully covered by acoustic panels, gypsum or wooden panelling. It is installed beneath the finish, not as the finish.

Is the foam fire rated?

Standard grade is supplied non-FR. A UL 94 Class HS1 fire retardant grade is available on request, which is what most institutional, government and tender projects specify.
