Scope

  • Sound insulation of partition walls between different users in public or private residential buildings.
  • Insulation of downspouts in commercial premises.
  • Insulation within the airtight chambers of wall linings and floating ceilings for low, medium and high frequencies in low-noise commercial premises.
  • Renovation of partition walls between different users in residential buildings.

Advantages & Benefits

  • Sound insulation for noisy premises with night-time DnTA>65 dBA.
  • By increasing the mass of lightweight walls, a higher acoustic performance is achieved.
  • High flexibility, allows for continuity of insulation in difficult junctions, such as corners.
  • High tensile strength and nail-tear strength, can be installed mechanically.
  • As a membrane resonator, it provides isolation at low frequencies.
  • In downpipes, it prevents noise from entering the pipe.
  • Low thickness with high acoustic performance.

Indications and Important Recommendations

  • The facade cladding in a building must end at the dividing wall between different users. See SPD 2.1
  • The air chambers must be completely airtight.
  • 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 the floating roof with installations in the proposed solution in commercial premises. See SPD 4.4 and files TEF3 and TEF4
  • In order to improve the performance of the roofing system, it is possible to place a screed perpendicular to the joists every 40 cm prior to the installation of the product. The product is then fixed with a sheet metal screw and washer.
  • For cutting, a MAKITA 4191 DW water-cooled low speed radial cutting machine or similar shall be used, with a MAKITA 85 - 6 asphalt cutting disc. ELYWOOD SAW BLADE 3-3 / 8 ”x 15 mm.
  • Impact sound insulation must be used. See "Sound Insulation Solutions Manual" sheets from AA01-AA04.
  • It should be taken into account that this product is part of a Sound Insulation system, so the Danosa Building Solutions Catalogue, Sheets AA23, AA31 and AA51, should be taken into account. The Danosa "Implementation of Sound Insulation 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
  • If a battery-powered drilling machine is used (never with a mains power cable), the drill bit can be soaked in water to prevent the drill bit from becoming embedded in the asphalt.

Handling, storage and preservation

  • The product itself is not classified as hazardous and is not toxic to the environment.
  • Store in covered and ventilated places that comply with current legislation regarding storage.
  • Consult the product safety data sheet.
  • The product may present a colour variation due to the mixture of fabrics, or the yellow colour may darken with the passage of time. This variation in appearance does not affect the acoustic conditions of the material.
  • In all cases, the Occupational Safety and Hygiene standards, as well as the standards of good construction practice, must be taken into account.
  • Stable at room temperature. Avoid being at temperatures above 80ºC as that would alter the material’s properties, accelerating its degradation.
  • No personal protection is required during transportation and handling. During application, appropriate measures must be taken with regard to the handling of machinery (mechanical fixing) or the application of adhesives via solvents.
  • For further information, please contact our Technical Department.
  • Preferably transport on complete and packed pallets in order to avoid possible alterations to the product during transport.
