Description

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 A has an exposed grid system comprising of Ecophon Combison Duo A tiles and Ecophon Connect grid systems, with an approximate weight of 14 kg/m². Each tile is demountable.


Ecophon Combison Duo E has a recessed visible grid and a regular edge design, creating a ceiling with a shadow effect that accentuates each tile and partially conceals the grid system. It consists of Ecophon Combison Duo E tiles and Ecophon Connect grid systems, with an approximate weight of 14 kg/m². The visible surface of each tile is approximately 10 mm below the grid. Each tile is demountable.


Features and benefits:

  • 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 primed.
  • The grid is manufactured from galvanized steel.
