Anyone who works in an office building knows how nice it is to have a little natural light to offset the fluorescent glow. But there are a few drawbacks, including computer glare and damaging ultraviolet (UV) rays.
UV radiation is part of the natural energy produced by the sun. On the electromagnetic spectrum, UV light has shorter wavelengths than visible light, so your eyes can’t see UV, but your skin can feel it. Two types of UV light are proven to contribute to the risk for skin cancer: ultraviolet A (UVA), which has a longer wavelength, and ultraviolet B (UVB), which has a shorter wavelength. Both UVA and UVB rays can cause sunburn and tanning, which damage the DNA in your skin cells and increase your risk for skin cancer. UVA rays also cause the unwelcome signs of premature aging, including dark spots and wrinkles. Those UVA rays account for up to 95 percent of the UV radiation reaching the Earth’s surface and are quite good at finding you. They can bounce off reflective surfaces like water and, most relevant during the workday, they can penetrate window glass. If you’re sitting next to a window on a sunny day, those UVA rays hitting your skin are doing damage.
3M Window films block both UVA and UVB radiation (window film can block up to 99.9 percent of UV radiation) and even though its UV-blocking benefits are normally the main reason for installing it, once installed you will immediately notice a few more perks once the film is fully installed in your home or office. The mid-afternoon glare that usually seeps through the window will diminish significantly. You will also find that your home or office will be more temperate thanks to the film, keeping the afternoon sun from heating up your home or office. Also, when the weather is cooler, it reflects the heater’s warmth back into the office, rather than letting it escape out.
Reducing UV radiation is not only good for the home or working environment but it is good for your skin and health too. The Skin Cancer Foundation recommends 3M window films for UV reduction and a list of recommended films is available from The Skin Cancer Foundation website here: https://www.skincancer.org/recommended-products/
