Xiaomi YU7 Window Film Necessary?

Q: Just got Xiaomi YU7, is it still necessary to apply heat insulating film on the windows?

A: For vehicles to achieve good sun protection and heat insulation, the key lies in the performance of the sunroof and windshield, as these two pieces of glass receive direct sunlight and have the largest area. All Xiaomi YU7 models feature a laminated glass windshield with triple silver coating, achieving 99.5% UV blocking rate and 97.6% infrared blocking rate. The sunroof of Xiaomi YU7 Standard and Pro versions is also laminated glass with double silver coating, achieving 99.9% UV blocking rate and 99.1% infrared blocking rate. Xiaomi YU7 Max is equipped with the latest generation EC dimming sunroof, achieving not only 99.85% maximum shading rate but also 99.9% UV and infrared blocking rate, further enhancing heat insulation. Moreover, all Xiaomi YU7 models have laminated glass for the four door windows as standard, with a UV blocking rate of 99.9%; the infrared blocking rate for the front windows is 77.23%, while for the rear windows, due to privacy glass, it improves to 80.09%. Xiaomi YU7 has undergone high-temperature sun exposure tests; after being exposed at 38°C for 1.5 hours, the interior temperature was even lower than some models with physical sunshades. Therefore, the sun protection and heat insulation performance of Xiaomi YU7 glass is already excellent, meeting most users’ needs, so you can consider not applying extra film. Additionally, for enhanced comfort, Xiaomi YU7 includes an “In-Car High Temperature Protection” function. If the car is exposed to sun outdoors, you can enable this in “Settings > Services > In-Car High Temperature Protection”; the vehicle will monitor interior temperature and automatically turn on air conditioning to lower it. Specific instructions and precautions can be found in the user manual. You can also remotely start or schedule air conditioning via the Xiaomi Car APP for a comfortable cabin temperature upon entry.
