It's a known fact that polycarbonate is highly transparent to visible light, with transmission rates on par if not better than all thermoplastics, and offer better light transmission than many kinds of glass.
For those requiring only maximum visible light penetration, VULCAN Valuview Clear polycarbonate sheets provide maximum visible light penetration, and LiteGuide which provide maximum but glare free visible light penetration.
What if you wanted maximum visible light penetration but at the same time, minimum heat buildup? In the past, people could only choose one over the other, because heat reduction was automatically associated with lower light penetration. Not any more.
With improvements in machinery and material technology, VULCAN is now able to meet both demands on the same sheet.
VULCAN Solarshield Polycarbonate sheets not only provide maximum visible light penetrations, identical to glass, but also blocks Infrared (IR) radiation to prevent heat buildup, which share similar properties with Low Emissivity (Low-E) glass.
