UV, fading and window film: what film can and can't prevent
Last revised October 26, 2026 · Published by Shore Tint & More, a 3M Authorized Window Film Dealer. Editorial disclosure
UV is one contributor, not the only one
Manufacturers commonly rate quality films as blocking a very high percentage of ultraviolet radiation; check the data sheet for the exact figure. But fading also comes from visible light and solar heat, plus humidity and the dyes and finishes in your floors, rugs and artwork. Some materials fade quickly no matter what.
What helps most
- Choose a film that reduces visible light and heat as well as UV, if the room can tolerate a little less brightness.
- Rotate rugs and move artwork occasionally.
- Use shades during the brightest hours on west and south glass.
- For valuable art, ask a conservator — film is not a museum-grade solution on its own.
About 'no fading' promises
No film eliminates fading. Be cautious of anyone guaranteeing it. Film warranties typically cover the film itself, not your furnishings.
