SSG® Luminescent Glass illuminates in the dark. It is the result of glass combined with luminous coatings to give a special visual effect in the absence of light. The special coating gets energised by normal lighting to glow in the dark. SSG® Luminescent Glass is available in heat-strengthened, tempered on clear or tinted glass substrates either in full coat or custom patterns. Coloured versions can also be achieved with colour PVBs in laminated glass.
