Ecophon Master™ CSuitable 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, 3rd generation 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. The grid is manufactured from galvanized steel.

The tiles are not demountable.

Cleanability

Daily dusting and vacuum cleaning. Weekly wet wiping.

Visual appearance

White Frost, nearest NCS colour sample S 0500-N, 85% light reflectance (of which more than 99% is diffuse reflection). Retro reflection coefficient 63 mcd/(m²lx). Gloss < 1.

Influence of climate

The tiles withstand a permanent ambient RH up to 95% at 30°C without sagging, warping or delaminating (EN 13964).

The tiles are also available for especially demanding hot and humid conditions. Please contact Ecophon for specifying your project.

The glass wool core of the tiles is tested and classified as non-combustible according to EN ISO 1182.

mechanical properties

Additional live load has to be fixed to the soffit.

Installation

Installed according to installation diagrams, installation guides and drawing aid. For information regarding minimum overall depth of system see quantity specification. Rendered surfaces must have sufficient strength to be able to carry the load imposed by the tiles. If doubts, test gluing should be carried out. The surface should always be dry and clean. For best result the surface should be even.
