Danosa FONODAN 50 is sound proofing, acoustic barrier designed for acoustic isolation of partition frames.

Danosa Fonodan 50 is a two layer product made of a self-adhesive high density bitumen membrane thermally bonded to a cross-linked polyethylene. FONODAN 50 acoustically works as spring between the gypsum board and frame.

Uses:

  • Acoustic Isolation for metal frame partition systems, eg gypliner.
  • Acoustic Isolation for floor mounted stud partitions.
  • Self-adhesive anti-resonant strip for the improvement of the plasterboard structure.
  • Sound proofing for service penetrations.
  • Anti-resonant strip for metal structures on tiled roofs.
  • Impact sound insulation of floorboards.

Advantages of Danosa Fonodan 50:

  • Acoustic insulation DnTA>50 dBA.
  • Shifting the coincidence frequency reduces the lack of privacy caused by the loss of insulation at these frequencies, where the human ear is most sensitive.
  • Easy and quick to install.
  • High resistance to tearing.
  • Improvement of airborne sound level between rigid elements ΔRA>3 dBA.
  • Improves the sound insulation of partition walls or wall linings in single-panel systems by minimising the hollow sound.

Installation Guide:

Preliminary operations

  • The channel is riveted to the floating floor and the roof. See Danosa Solutions Manual DIV2 and FCH3.
  • The gutter is riveted to the floating floor and the roof. See tab AA 11 and AA 12 of the Danosa Sound Insulation Solutions Manual.
  • The uprights are then placed every 60 or 40 cm depending on the height and the plasterboard system.
  • Once the structure is in place, the FONODAN 50 is adhered following the steps below:

Laying FONODAN 50

  • The non-stick plastic is removed from the beginning of the roll and the product is glued to the side of the channel.
  • Once the beginning of the roll is attached, the plastic is removed and the band is pressed to the side of the carcass.
  • The same procedure is followed for the uprights.
  • It is not necessary for the FONODAN 50 strip to be completely end-to-end, as there may be small discontinuities. The important thing is that it is fixed in such a way that it cushions the rigidity of the panel.
  • Once the entire structure is covered on the plate side, it is fixed with sheet metal screws according to the proposed system.
  • The gypsum plasterboards are sealed and taped according to the criteria of the respective manufacturer.

Laying on tile battens.

  • Once the battens have been laid, the Fonodan 50 is fixed according to the previous section.

Laying on wooden battens.

  • Once the levelling mortar has been cleaned and the timber framework has been prepared, it is fixed to the base of the framework as described in “Laying Fonodan 50”.
  • For greater effectiveness of the system, it is recommended to fix the framework with staples on top of it, making a floating frame.
  • Finally, fix the decking to the framework with nails 2 cm longer than the thickness of the wood strip

Indications and Important Recommendations

  • The floating mortar must be strong enough to prevent cracking. (See SPD No. 1.3).
  • The facade cladding in a building must end at the dividing wall between different users. See SPD 2.1
  • Installations or elements liable to cause vibrations inside the partition walls shall be protected by cross-linked PE shells. See SPD 2.3
  • The structure’s anchorages must not be fixed to the building structure except on the roof. See SPD 3.2
  • In order for the system to be perfectly determined by the insulation, no unwanted lateral transmissions must occur.
  • Setting back the partition wall on the pillars.
  • Impact sound insulation (e.g. Impactodan System) must be used. See SUF1, SUF2 and SUF3 data sheets.
  • It will be taken into account that this product is part of a Sound Insulation system, so the Danosa Constructive Solutions Catalogue, Sound Insulation Commissioning must be taken into account. “Details of Singular Points” (SPD), as well as the rest of the Danosa documentation.
  • Isolated sewage disposal systems with FONODAN BJ or ACUSTIDAN. See BAJ1 and BAJ2 sheet of “Danosa Sound Insulation Solutions.
