Suitable for open plan offices or other premises where strict demands are made on good acoustics and speech intelligibility. For applications where a suspended ceiling with a concealed grid is required, but individual tiles must be easily demountable. Ecophon Master™ Ds has a concealed grid and symmetrical edge design, allowing easier assembly, integration of light fittings and ventilation. The ceiling has an even appearance, with the bevelled edges forming a discreet groove between the tiles. The tiles are easily demountable. The systems consist of Ecophon Master™ Ds tiles and Connect™ grid systems, with an approximate weight of 6 kg/m². The tiles are manufactured from high density glass wool. The visible surface has an Akutex™ FT coating and the back of the tile is covered with glass tissue. The edges are painted. For best performance and system quality, use Connect™ grid and accessories. The grid is manufactured from galvanized steel. The system is patented.
