UV Protection: If allowed to pass freely through your window glass, Ultraviolet-A and Ultraviolet-B rays can damage your home's contents like draperies, furniture, artwork, heirlooms, photos, and flooring. Zo-e-shield provides the ultimate in protection by blocking 95%-99.9% of UV-A and UV-B, while allowing the transmission of solar energy and ambient light.
EasyCare™: Who like cleaning windows? Nobody. EasyCare™ is a glass technology that keeps your glass cleaner, longer. Unlike ordinary glass, which causes water to bead up and dry spotty, EasyCare™ makes the glass smoother than ordinary glass causing water to spread out and sheet off the glass taking dirt and grime with it.
I have Weather Shield windows with this glass. My upholstery has not gotten bleached from the sun like my old windows did to my other furniture. It really does protect.
