A quick Google search on “UV window protection” indicates the answer is NO. With over 31,000 results, the first page is filled with UV-blocking films for sale that provide protection. That sun faded sofa at grandma’s house is a great visual reminder that UV does indeed pass through glass.
And what about in the car? All of a car’s windows will filter out the sun’s short-wave, UVB rays (all glass will filter UVB, but only the windshield in cars comes partially treated against the sun’s UVA rays). SunAWARE found that researchers at the University College Hospital in Besancon, France concluded that “participants showed significantly more clinical signs of facial aging on one side of their face due to driving or working close to windows over many years.”
Lucky for us, there are some easy solutions to protect from UV, including UVA-protective film for cars, homes and businesses. And if you’re not sure if your windows are treated, protect yourself with sun protective clothing and sun sleeves, UV sunglasses and the daily use of broad spectrum sunscreen.
Be SunAWARE and be Safe!
