Signal-Friendly Film

A signal-friendly film is one that does not attenuate radio, GPS, mobile or ERP signals — essentially any non-metallic chemistry, including all ceramic and most multi-layer films.

In Singapore, signal transparency is not optional. ERP gantries read the In-Vehicle Unit through the windscreen, GPS lock matters for navigation, and Bluetooth audio underlies CarPlay and Android Auto. Any tint that attenuates those signals is a problem.

All ceramic and multi-layer optical films are signal-friendly because the rejection mechanism is dielectric, not conductive. Metallised, sputtered and hybrid films with metallic content can attenuate signals to varying degrees.

When in doubt, ask the workshop for a confirmation that the film is "non-metallic" or "dielectric" — Platinum99 and similar premium nano-ceramics meet this standard.
