Ultraviolet Radiation

Ultraviolet (UV) radiation is the high-energy portion of the solar spectrum below 380 nm, divided into UVA, UVB and UVC, with UVA and UVB reaching Earth's surface and damaging skin and interior materials.

UVA (315–380 nm) penetrates deep into skin and is the primary cause of premature ageing and melanoma. UVB (280–315 nm) causes sunburn. UVC is absorbed by the atmosphere and does not reach the ground.

Premium window films reject 99%+ of UVA and UVB across the spectrum. This is both a health benefit (skin protection on long drives) and a preservation benefit (dashboard, leather, fabric and plastics survive longer).

For drivers spending hours in Singapore sun — taxi, private hire, sales — UV protection is one of the more underrated benefits of quality window film.
