UV Rejection (UVR)

UV Rejection is the percentage of ultraviolet radiation (typically 300–380 nm) a film blocks; quality tints reject 99% or more, protecting skin and interior trim from sun damage.

Ultraviolet radiation accelerates skin ageing, raises melanoma risk, and is the primary driver of dashboard cracking, leather hardening and fabric fade. Most quality window films — even budget carbon tints — reject 99% of UVA and UVB.

UV protection is therefore not a meaningful differentiator at the high end. The real performance question is what happens with infrared heat. UV rejection is the floor; IR rejection and total solar energy rejection are the ceiling.

For Singapore drivers who spend long hours in equatorial sun, UV rejection is a baseline expectation. Always confirm the film's certified UV figure before installation.
