Danosa M.A.D. 4<\/strong> is a high-density acoustic membrane made of modified bitumen, designed as an anti-resonance material<\/strong> to significantly improve sound insulation, especially in the low-frequency range. The membrane is reinforced with fiberglass fabric and has a double-sided polyethylene film coating, ensuring stability, durability, and easy integration into various acoustic systems. <\/p>\n

Due to its higher mass, Danosa M.A.D. 4 provides higher efficiency compared to thinner membranes<\/strong> and is a reliable, eco-friendly alternative to lead sheets.<\/p>\n","protected":false},"excerpt":{"rendered":"

Application<\/strong><\/h3>\n

Danosa M.A.D. 4 is used to increase the sound insulation of walls, ceilings, and industrial structures, such as:<\/p>\n

    \n
  • \n

    Anti-resonance layer between porous sound-absorbing materials, where it acts as a panel absorber with high efficiency at low frequencies<\/p>\n<\/li>\n

  • \n

    Intermediate layer between rigid elements (e.g., plasterboard) to improve insulation against low-frequency noise<\/p>\n<\/li>\n

  • \n

    Component in mass\u2013spring\u2013mass<\/strong> systems (in combination with mineral or rock wool) to significantly increase overall acoustic performance<\/p>\n<\/li>\n

  • \n

    Industrial applications \u2013 to provide additional acoustic mass and reduce resonances in metal structures<\/p>\n<\/li>\n<\/ul>\n
