System and product description
For use as a sound absorbing ceiling and for sound insulation between rooms if the partitions do not extend all the way up to the soffit. Also suitable for sound reduction of vertical noise, generated by ventilation, foot steps etc. Ecophon Combison Uno Ds is installed in a suspended grid system, creating a ceiling with a smooth appearance. The bevelled edges create a narrow groove between each tile. The tiles are demountable.

The system consists of Ecophon Combison Uno Ds tiles and Ecophon Connect grid systems, with an approximate weight of 11 kg/m². The tiles are manufactured from high density glass wool, with a bonded gypsum board (9 mm) on the back of the tile. The visible surface has an Akutex FT coating and the edges are primed.

For best performance and system quality, use Ecophon Connect grid and accessories. The grid is manufactured from galvanized steel.
