Do Windows Block UV Rays in Your Home?
Summary: Do Windows Block UV Rays in Your Home? Most standard windows don’t block enough UV—they stop UVB but let damaging UVA rays through, which can age skin and fade interiors. UV rays still harm you indoors, especially if you spend time near large windows or in sun-filled rooms. Tinted glass helps, but not all tint is equal—aftermarket films can degrade or void warranties, while built-in UV-blocking glass is safer and longer-lasting. Modern replacement windows offer better protection with built-in Low-E coatings, energy savings, and clear, glare-reducing options. Davis Window
