Automotive tinting specifics
Windshield Tint
Windshield tint is window film applied to the front windscreen; in Singapore the LTA requires it to maintain at least 70% Visible Light Transmission across the combined glass + film stack.
The front windscreen is the most regulated piece of glass on a Singapore-registered vehicle. The LTA's 70% VLT minimum exists because the windscreen is the driver's primary forward visibility surface, including at night.
The technical implication is that windshield tint must be a spectrally selective film, one that rejects heat and UV without darkening the glass. A film like Platinum99 Plus is designed specifically for this application.
Installation on the windscreen is also more demanding than side windows because of the compound curvature and the importance of dust-free finish — any contaminant is visible at eye level.
