Regular single pane windows are really only able to reflect about 25 percent of UV radiation. That same single pane window, with a coat of Low-E applied to it, is now able to reflect around 75 percent of UV radiation. If you have multi-pane windows, each with a Low-E coat, you will have rock solid, year-round protection for your entire home.
If you are moving into an older home, or you currently live in an older home and are wondering whether or not your current windows and doors are protected from UV, you might be surprised to find that they are not. If however, you are ordering new energy efficient doors and windows, they most likely already come with anti-UV coatings applied to the glass, so you can rest assured that you are getting the UV protection you need. There are different UV coating levels for different windows, and for different levels of protection.
If you choose the right combination of glass coatings, spacers and gas fillings, you can do wonders for your home’s energy efficiency and ensure that your windows are blocking out the vast majority of UV rays all year round.
