System and product description

Suitable for schools, open plan offices or other premises where strict demands are made on good acoustics and speech intelligibility, and where demountability is vital. Ecophon Master A has an exposed grid system. Each tile is easily demountable.

The system consists of Ecophon Master A 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 primed.

To improve absorption in the low frequency range, Master Extra Bass can be 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.
