Description Technical features and measures Related documentation

M.A.D.6 (short for Membrana Acústica Danosa, or 'Danosa Acoustic Membrane' in English) is a 6mm thick 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).

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.

Indications and Important Recommendations

For very heavy ceilings, it is recommended to use a ceiling grid system consisting of primary and secondary profiles. This system helps to spread loads if any shock absorber anchorage point breaks. See SPD 4.3.
The ceiling dampers are always anchored to the floor joist or a reinforcing construction element. See SPD 4.2
The facade cladding in a building must end at the dividing wall between different users. See SPD 2.1
In dry wall cladding for heights over 4 m, we recommend the use of elastic fasteners. See SPD 2.5
Gypsum plasterboards must always be anchored to the galvanised steel auxiliary structure, never use plate-plate screws.
Partition walls must be plastered with at least 1 cm. See SPD 3.
Partition walls should not be anchored to structural elements (except for roofs in dwellings) such as pillars and facades. In order to maintain the stability of the system, the tiling element must be bonded to the internal floating partition walls.
It is not possible to perforate with installations in the proposed solution in commercial premises located in tertiary buildings or commercial ground floors in residential buildings. See SPD 2.3 and SPD 4.4.
Impact sound insulation must be used. See "Sound Insulation Solutions Manual" sheets from AA01-AA04.
It should be borne in mind that this product forms part of A Sound Insulation system, so the Danosa Building Solutions Catalogue, sheets AA13 to AA15; AA23 to AA25; and AA30 to AA33, Installation of Sound Insulation, should be taken into account. Details of Singular Points (SPD), as well as the rest of the Danosa documentation.
In the case of central heating or water intake installations, decoupling by means of a cross-linked polyethylene shell. See SPD 1.2
