Spectrally Selective Film
Spectrally selective film is engineered to block specific wavelength bands (typically near-infrared) while letting visible light through, giving high heat rejection with low tint darkness.
Spectrally selective films use multi-layer optical engineering or precisely-tuned nano-ceramic particles to target specific solar wavelengths. The result is a film that can be optically clear yet still reject 60%+ of total solar energy.
This is the chemistry behind windscreen-legal films — the LTA's 70% VLT rule forces manufacturers to develop films that don't darken the glass but still meaningfully cut heat.
Spectrally selective films are typically the most expensive segment. Platinum99 Plus falls into this category. They are the appropriate choice for owners who want the maximum legal performance on the windscreen.
