DANOFON is a multilayer composite made of a high density bitumen based membrane between two porous textile layers. Acoustically it works as a low-medium and high frequency insulation.

Installation video



  • Sound insulation of partition walls between different users in public or private residential buildings.
  • 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

  • Acoustic insulation DnTA>50 dBA.
  • High flexibility, allows for continuity of insulation in difficult encounters.
  • Easy installation, can be mechanically fixed or adhesively bonded.
  • Greater privacy, isolation at low, medium and high frequencies.
  • Low thickness with high acoustic performance.

Instruction for Use

An installation of the DANOFON shown in the following pictures:

Indications and Important Recommendations

  • The final plaster or mortar finish of the partition walls must be at least 1 cm thick.
  • The facade cladding in a building must end at the dividing wall between different users. See SPD 2.1
  • Details can be found in the document "Sound Insulation Installation. Singular Point Details" (SPD) and in the DANOSA Solutions Manual SUF1 SUF2 SUF3.
  • 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
  • Impact sound insulation must be used (e.g. Impactodan System) See AA01 sheet.
  • Impact sound insulation (e.g. Impactodan System) must be used. See SUF1 SUF2 and SUF 3 sheet.
  • If the heating installations were central or water intake, decoupling by means of self-adhesive TAPE. 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.
  • Isolated sewage disposal systems with FONODAN BJ or ACUSTIDAN. See BAJ1 and BAJ2 sheet of "Danosa Sound Insulation Solutions.

Handling, storage and preservation

  • Store in covered and ventilated places that comply with current legislation regarding storage.
  • Consult the product safety datasheet.
  • The product itself is not classified as hazardous and is not toxic to the environment.
  • 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.
  • Stable at room temperature. Avoid being at temperatures above 70ºC 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.
  • Preferably transport on complete and packed pallets in order to avoid possible alterations to the product during transport.
  • In all cases, the Occupational Safety and Hygiene standards, as well as the standards of good construction practice, must be taken into account.
