Danosa Fonodan is a two layer product made of a self-adhesive high density bitumen membrane thermally bonded to a cross-linked polyethylene. Danosa Fonodan acoustically works providing the acoustic mass of the tube body and removing resonant frequencies.

Scope

• Increases insulation in the noisiest area of the downpipe, such as junctions and elbows.
• Reduces noise from siphon pipes and sagging pipes inside false ceilings.
• Specially designed to minimise noise from drainage pipes in all types of buildings.

Advantages & Benefits

• Double reinforcement at bends and junctions increases acoustic performance.
• Easy and quick to install.
• High resistance to tearing.
• Prevents mould growth in the insulation.
• Insertion loss IL>17 dBA (complete system).
• Low thickness, easily adapts to the downpipe.
