3M Crystalline

3M’s Crystalline Series is a range of patented multi layer and metal free nano-technology optical films. The films have more than 200 layers in what is less than the thickness of a 3M Post-ItNote®. This unique technology is the reason a virtually clear film can reject more heat than darker films. They provide a high performance combination of high visible light transmission, low visible light reflectivity, with exceptionally high heat gain reduction capabilities. Additionally, the films block almost the entire range of UVA and UVB rays which are the main cause of fading and skin damage.
