For use as a suspended ceiling with high sound absorption 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, footsteps etc. Ecophon Combison Duo E has a recessed visible grid and a tegular edge design, creating a ceiling with a shadow effect that accentuates each tile and partially conceals the grid system. The visible surface of each tile is approx. 10 mm below the grid. Each tile is demountable.

The system consists of Ecophon Combison Duo E tiles and Ecophon Connect grid systems, with an approximate weight of 14 kg/m². The tiles are manufactured from high density glass wool, with a bonded gypsum board (13 mm) on the back of the tile. The visible surface has an Akutex™ FT coating and the edges are painted. For best performance and system quality, use Ecophon Connect grid and accessories. The grid is manufactured from galvanized steel.
