DANOSA M.A.D 4 Bituminous Membrane - 6m x 1m

• 4mm thick high-density bitumen acoustic membrane
• Specially designed for low-frequency sound control
• Acts as an anti-resonant material to improve system insulation performance
• Increases the mass of lightweight walls for better acoustic protection
• Enhances insulation without requiring large cavities
• Converts acoustic energy into dynamic energy when used between insulation layers
• Can be installed by stapling or using the self-adhesive M.A.D. variant
• Improves resonance performance when adhered to galvanised steel sheets

• Industrial insulation: Provides acoustic mass and anti-resonance properties when applied to galvanised steel sheets.
• Partition walls: Improves low-frequency insulation when used between rigid elements such as gypsum plasterboard.
• Ceiling and wall systems with spring elements: Enhances isolation performance in suspended ceilings and floating wall constructions.
  
  Installation Guidance
  
• Follow Danosa SPD guidelines and sound insulation system recommendations for proper installation.
• Ensure partition walls are plastered with at least 1 cm and are not anchored directly to structural elements, except at the roof where necessary.
• Apply impact sound insulation where required, following AA01–AA04 guidelines in the Danosa manual.
• Decouple heating and water intake installations with cross-linked polyethylene shells to avoid sound bridging.
• Avoid perforating the system with service installations in certain commercial building applications as per SPD 2.3 and SPD 4.4.
• Anchor ceiling dampers to floor joists or reinforced elements, and use ceiling grid systems with primary and secondary profiles for heavy ceilings.
• Always fix gypsum plasterboards to galvanised steel auxiliary structures, avoiding direct plate-to-plate screws.
• For drywall cladding over 4 m high, use elastic fasteners for added stability.

How does Danosa M.A.D 4 work?

Danosa M.A.D 4 works by absorbing and decoupling sound vibrations, preventing noise from traveling through the floor structure. This helps reduce both impact noise (like footsteps) and airborne sound (like conversations or music) from penetrating between rooms or floors.

Does Danosa M.A.D 4 work with underfloor heating?

Yes, Danosa M.A.D 4 is compatible with underfloor heating systems, but care should be taken to ensure the heating system is installed correctly to avoid any performance issues.

Is Danosa M.A.D 4 moisture resistant?

Yes, it is moisture-resistant, making it suitable for use in areas where humidity might be present, such as kitchens or bathrooms, provided it is installed according to the manufacturer's guidelines.
