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 A has an exposed grid system. Each tile is demountable.

The system consists of Ecophon Combison Uno A tiles and Ecophon Connect grid systems, with an approximate weight of 13 kg/m².
