System and product description
Suitable for schools, open plan offices or other premises where strict demands are made on good acoustics and speech intelligibility. Ecophon Master E has a recessed visible grid and a tegular edge design, creating a ceiling with a shadow effect that accentuates each tile and partially conceals the grid system. The visible surface of each tile is 10 mm below the grid. Each tile is easily demountable.

The system consists of Ecophon Master E tiles and Ecophon Connect grid systems, with an approximate weight of 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, beta and gamma. The back of the tile is covered with glass tissue. The edges are painted.

For best performance and system quality, use Ecophon Connect grid and accessories. The grid is manufactured from galvanized steel.
