HI-TECH film is a high-performance, nano-ceramic automotive window film from HI-TECH’s Crystalline Series, known for its excellent heat rejection (around 50-60%), 99.9% IR99%UV protection, and superior clarity with minimal glare, making it ideal for windshields, while remaining signal-friendly for GPS/phones. It uses advanced multilayer optical film technology to keep car interiors cooler without dark tint, offering high Visible Light Transmission (VLT) and Total Solar Energy Rejection (TSER).
