Ecophon Master™ C

Suitable for schools, open plan offices or other premises where strict demands are made on good acoustics and speech intelligibility. Ecophon Master C is installed in a suspended grid system or directly to the soffit, creating a ceiling with a smooth appearance. The bevelled edges create a narrow groove between each tile. The tiles are not demountable.

The systems consist of Ecophon Master C tiles and Ecophon Connect grid systems, with an approximate weight of 5,5 kg/m². The tiles are manufactured from high density glass wool. The visible surface is available with three different surface coatings to meet different sound absorption needs: alpha (Akutex T coating), beta and gamma. The back of the tile is covered with glass tissue. The edges are painted. The grid is manufactured from galvanized steel.
