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.
