The entire Eggboard collection is based on the principle of acoustic absorption to limit sound reverberation, particularly with respect to human voice frequencies. A vertical suspension and a number of panels with grazing light intended for wall or ceiling installation are the new elements making up the lightscape and ensuring perfect environmental quality. They both work freely on the lighting performances that can be combined with the acoustic element. The suspension version can combine indirect diffused light with direct controlled light thanks to the patented Eggboard Matrix optical units. In the wall and ceiling versions, grazing light can be associated on each side.
