I just picked up my Xiaomi SU7 Ultra. Is it necessary to apply heat-insulating film to the windows?

You do not need to apply additional film to your Xiaomi SU7 Ultra to achieve an excellent sun protection and heat insulation experience. The front windshield of the Xiaomi SU7 Ultra uses triple-layer silver-coated glass, the panoramic roof uses double-layer silver-coated glass, and the four door windows are fully upgraded with acoustic laminated glass featuring UV-IR coating technology. In addition to further optimizing mid-to-high frequency noise in the cabin for a quieter and more comfortable environment, its ultraviolet sun protection and heat insulation capabilities have been significantly enhanced. Therefore, the sun protection and heat insulation performance of the SU7 Ultra's glass is excellent, and film application is unnecessary. If you still wish to apply film, especially on the front windshield, we recommend choosing a high-transparency1 film to avoid affecting your driving visibility.
