The 3M Ceramic Series products are available in three visible light transmissions to meet your specific needs - CM 30, CM 40 and CM 50. Using nanotechnology 3M created ceramics so fine they are not only invisible to the naked eye they are imperceptible with an ordinary microscope. These ceramics allow us to create a film that is tough, won’t corrode and is so clear your view will remain beautiful. The ceramic series will look good not just the first year, but for years to come. Sputtered metal films can corrode, often changing color on the edges. Films that rely on dyes are prone to fading over time, changing to a purplish hue. By using advanced ceramics, our film retains its color and appearance over time. With energy costs seeming to increase every year, 3M Ceramic Series films are a great way to save money and help the environment. By rejecting up to 59% of the total solar energy and up to 80% of the heat-producing infrared rays, your cooling system will work less and you’ll be able to maintain a more even temperature throughout your home or office. Depending on the size of your home or office you could save hundreds or thousands of dollars each year. Creating a beautiful home or office takes an investment of time and money. Damaging ultra-violet (UV) rays from the sun can ruin that investment, fading your fabrics, photos, artwork, wood, carpet and wallpaper. But, because our advanced film blocks over 99% of UV rays, you can fully enjoy your beautiful interiors for years to come. In addition to its low reflectivity that doesn’t detract from the beauty of your architecture, one of the Ceramic Series’ most impressive characteristics is its amazing clarity. Day or night, 3M's film has a clarity that rivals glass.
