Automotive tinting specifics
Sunroof Tint
Sunroof tint is window film applied to a vehicle's sunroof or panoramic roof glass, primarily to reject infrared heat and reduce cabin heating from overhead sun.
Sunroofs — especially the large panoramic roofs on EVs like the Tesla Model Y, Polestar 2 and BYD Sealion — are massive radiant heat surfaces. Without tint, the sun beats directly onto occupants' heads and the headliner, raising cabin temperature significantly.
Tinting a panoramic roof typically takes more film and more installation time than a single side window because the glass area is large and often double-curved. Some OEM glass already has a tint layer baked in; an aftermarket film stacks additional rejection on top.
For Singapore drivers with panoramic sunroofs, a nano-ceramic film is almost essential — interior temperature drops noticeably and aircon load decreases.
