DANOSA ACOUSTIC MEMBRANE M.A.D.2
Danosa Acoustic Membrane M.A.D.2 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)。

Test Report
SCOPE
Used between rigid elements such as plasterboards to improve the low frequency insulation。
Used between spring elements (fibers, rock wool) to increase the overall insulation treatment, improving significantly against low frequencies through the membrane effect within mass-spring-mass system。
It used as antiresonant material in industrial acoustic insulation, providing acoustic mass to the galvanized steel sheet。
