System and product description
For applications requiring a dark ceiling having low light reflection and good sound absorbing properties. Ecophon Sombra A has an exposed grid system. Each tile is easily demountable. The system consists of Ecophon Sombra A tiles and Ecophon Connect grid systems, with an approximate weight of 3 kg/m² (6 kg/m² with X-bass). The tiles are manufactured from high density glass wool. The visible surface is a matt black batch painted glass tissue and the back of the tile is covered with glass tissue. The edges are natural. For special applications i.e. cinemas, tiles with a sound reflecting surface, Sombra A/gamma, are available. To improve absorption in the low frequency range, Sombra X-bass can be installed on top of the suspended ceiling. For more information see application "Ecophon in Cinemas". For best performance and system quality, use Ecophon Connect grid and accessories. The grid is manufactured from galvanized steel.

For Acousticians
"Acoustical evaluation of rooms requires several room acoustic descriptors. Reverberation time alone is not enough!" Erling Nilsson / Acoustics Specialist Ecophon
