Yes, quality window film blocks up to 99% of UVA and UVB rays, the same UV that causes skin cancer, fades fabric, and damages timber floors. This FAQ explains how UV-rejecting film works, which products to choose, and what to expect for skin and interior protection.
How much UV does window tint block?
Genuine 3M window films block 99% of UV radiation (both UVA and UVB) across the entire visible-light spectrum. That's the same UV protection as SPF 1000+ sunscreen, applied permanently to your glass. Even clear, untinted films (3M Scotchshield, 3M Prestige Clear) achieve 99% UV rejection.
Do regular house windows block UV?
Standard glass blocks most UVB but lets through 50–75% of UVA, the long-wave UV responsible for premature skin ageing and interior fading. That's why timber floors fade in patches near windows even though the glass feels cool. UV-rejecting window film closes that gap.
Will UV-blocking film stop my furniture fading?
Window film blocks the single biggest cause of fading (UV ~40%), but fading also comes from visible light (~25%) and heat (~25%). For maximum fade protection, choose a spectrally selective or ceramic film that rejects UV, infrared radiation AND a portion of visible light. Most museums in Australia use 3M Prestige for exactly this reason.
Is window tint safe for skin protection?
The Skin Cancer Foundation recommends UV-protective window film as part of a comprehensive skin cancer prevention strategy, and 3M films carry their Seal of Recommendation. For anyone working near a window, driving long distances, or with photosensitive skin conditions (lupus, melasma, polymorphic light eruption), UV film makes a measurable difference.
Does clear film really block 99% of UV?
Yes. UV rejection is delivered by a chemical inhibitor layer in the film, not by the colour or tint level. 3M Prestige and Scotchshield Safety Ultra are visually clear (you can't tell the window is treated) but still block 99% of UV.
Which film should I choose for UV protection?
- Clear UV protection only: 3M Scotchshield Safety Ultra (great for north-facing apartments)
- Clear + heat rejection: 3M Prestige 70 (no visible tint, 97% IR rejection)
- Privacy + UV: 3M Night Vision 25 (one-way mirror look from outside)
- Maximum performance: 3M Ceramic Architectural CA35 (best heat + UV + glare balance)
UV rejection is only one part of what a film does — solar window film explains how infrared and total solar energy are handled as well.
