Trotec TroGlass Duo Night and Day, 3 mm - lastra quarto

Sign makers and display designers often need a material that looks completely different depending on the lighting. The Trotec TroGlass Duo Night and Day sheet offers exactly that: in daylight it appears as a deep opaque black, but when backlit it transforms into a brilliant translucent white. This 3 mm thick cast acrylic quarter plate (610 x 305 mm) is perfect for creating dynamic signage, POS displays, architectural models, and backlit panels that demand high visual impact.
