In order to avoid glare the PHOENIX ventilator can additionally be equipped with lighting grids. Apart from their function as smoke and heat extractor and ventilator, NSHE such as PHOENIX or FIREFIGHTER offer the additional benefit of allowing daylight to enter the building due to their polycarbonate multi-wall panel infill. Subject to the use of the area below the NSHE a disturbing glare might occur, which can be avoided, if lighting grids are laid on top of the fall-through safety grids of the system.
The lighting grids are made from 0.6 mm aluminium with a honeycomb size of 15 x 15 mm. Being 30 mm high the division bars offer a cut-off angle of 63°. The light opening of the grid (free section) is 92%.
