System and product description
Suitable for classrooms or other premises where strict demands are made on good acoustics and speech intelligibility, and where demountability is vital. Ecophon Master Rigid E has a recessed visible grid and a tegular edge design, creating a ceiling with a shadow effect that accentuates each tile and partially conceales the grid system. The visible surface of each tile is 10 mm below the grid. Each tile is secured in the grid by clips (patent pending), but fully demountable.

The system consists of Ecophon Master Rigid E tiles, Ecophon Extra Bass and Ecophon Connect grid system, with an approximate weight of 3,5 kg/m². The tiles are manufactured from high density glass wool utilizing the 3RD Technology. The surface is a reinforced sandwich construction. The visible surface has an Akutex™ FT coating. The product is also available with a sound reflecting surface (gamma) with the same visual appearance. The back of the tile is covered with glass tissue. The edges are painted.

Ecophon Extra Bass is used to improve sound absorption in the low frequency range, and is installed on top of the suspended ceiling. For best performance and system quality, use Ecophon Connect grid and accessories. The grid is manufactured from galvanized steel.
