Ecophon Master™ E

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 (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.

SOUND ABSORPTION: Test results according to EN ISO 354.
Classification according to EN ISO 11654, and the single value ratings for NRC and SAA according to ASTM C 423.
SOUND INSULATION: Dn,c,w=29 dB according to ISO 140-9 and evaluation according to EN ISO 717-1. CAC=31 dB according to ASTM E 1414 and evaluation according to ASTM E 413.
SOUND PRIVACY: AC(1.5)=190 (Master E/alpha) according to ASTM E 1111 and E 1110. Master E/beta and Master E/gamma are not suitable.
