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 F is installed directly to an existing plaster ceiling, boarding, battens or concrete, creating a ceiling with a smooth appearance. The bevelled edges create a narrow groove between each tile. The tiles are not demountable.

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 reinforced and painted. The weight is approximately 5 kg/m².
