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 offers 2 versions, one which provide maximum visible light penetration, and another 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 - look into the VULCAN Solarshield series for more information.
