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。

INSTRUCTION FOR USE

An installation of the Danosa Acoustic Membrane is shown in the following pictures:

1、Staple on 1st plate (wall)

2、Place the second plate (wall)

3、Staple on 1st plate (floating ceiling)

4、Set the 2nd plate (floating ceiling)
