LAMIN-MEMBRANE SPEAKER 2MM M. A. D. 2 (610001)

Is a sheet bituminous navy composed by a mástico bituminous modified bitumen with elastomer (SBS), using as a loading filler of baryta, and in their outer faces, a film of high density polyethylene of 50 and 100 GG. Developed to increase the insulation of building elements, to be an effective substitute for lead.
Its purpose is to:
1. Increase the mass of the walls.
2. Decrease the resonance frequency of the rigid materials.
3. Transform acoustic energy into dynamic by improving the isolation at low frequencies.

Conditions:
R sound Insulation in dB at 100 Hz between rigid elements 5 A. Acoustic Insulation in dB at 100 Hz between elements by springs 9.

MODE OF EMPLOYMENT AND FIELD OF APPLICATION:
It is used between rigid elements such as cardboard plates-gypsum to improve insulation at low frequencies of other isolates, both in vertical as in horizontal.
Also as support band for leave floating walls and structures out of cardboard-plaster. Used between elements springs (fibers, rock wool) to increase the global isolation of the treatment, a significant improvement in low fracuencias, (effect membrane within systems mass-spring-mass).
