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

Scope

• Impact sound insulation of floorboards.
• Self-adhesive anti-resonant strip for the improvement of the plasterboard structure.
• Anti-resonant strip for metal structures on tiled roofs.

Advantages & Benefits

• Acoustic insulation DnTA>50 dBA.
• By shifting the frequency of coincidence, the lack of privacy that occurs due to the loss of insulation at the previous frequencies (where the human ear is most sensitive) decreases.
• Easy and quick to install.
• High resistance to tearing.
• Improvement of airborne sound level between rigid elements RA>3 dBA.
• Improves the sound insulation of partition walls or wall linings in single-panel systems by minimising the hollow sound.
