Danosa Acoustic Bitminous Membrane

Danosa Acoustic Bitminous Membrane is a high density bitumen modified membrane specifically designed to behave as an anti-resonant material. It is an efficient substitute for lead sheets. Between porous absorbers materials works like a panel absorbers (most efficient at absorbing low frequencies).

Scope

It is used in industrial insulation as an anti-resonant material, providing acoustic mass to galvanised steel sheets.
It is used between rigid elements, such as gypsum plasterboard, to improve low-frequency insulation in both vertical and horizontal walls.
Used between spring elements to increase the overall isolation of the treatment, improving significantly at low frequencies.

Advantages & Benefits

By adhering to galvanised steel sheets, it improves the resonance of the sheet.
By increasing the insulation at low frequencies, cavaties used can be kept to a minimal size.
By increasing the mass of lightweight walls, a higher acoustic performance is achieved.
It shifts the resonance frequencies of the rigid elements making the insulation stronger.
Between insulators, it transforms acoustic energy into dynamics, improving insulation at low frequencies.
Easy to install by stapling to the surface or using M.A.D. Self-adhesive.
