BMW iX Panoramic Sunroof Smart Glass Replacement Costs USD 16K?! How to Maintain It?

This year (2022) BMW launched the new BMW iX pure electric travel series, which is very popular among car owners. It not only has an avant-garde and innovative appearance with a sense of future technology, but also has interior configurations and space performance that are among the best in its class. Among them, the panoramic sunroof adopts an Electronic Control Glass (PDLC) design, which not only can adjust the transparency to provide more privacy protection in the car, but also has the function of blocking ultraviolet rays, which enhances the visual and spatial sense. It can also be switched between transparent and atomized, which is highly discussed in Taiwan.

However, some car owners at home and abroad have shared that their sunroofs were broken due to gravel impact while driving, which caused a lot of discussion and usage doubts. Here we will briefly talk with you about why this situation occurs and how to maintain it to avoid similar situations.

The previous article explained to you "Reasons for the application of Electronic Control Glass” and “What technology is mainly used?”, so I won’t go into details in this article. Due to different application scenarios, the design specifications and weather resistance of Electronic Control Glass for automobiles and Electronic Control Glass technology partitions for general household use will be different. Considering the overall appearance design and accessory compatibility, the thickness of Electronic Control Glass skylights for cars is about 3 mm, while the thickness of Electronic Control Glass technology partitions for general household use is 10-12 mm. Glass thickness is inversely proportional to the impact resistance coefficient, and because the thinner the glass, the more difficult it is to strengthen technically, so it is also less able to withstand impact. In order to make up for this situation, it is recommended that car owners use it with an "safety film" (please refer to:Why do you need window tint film when buying a car? Wouldn't it be better to put black paper on it? Chapter 6'58'' introduces the test of safety film imported from the United States) A small investment can prevent car windows from cracking due to the impact of gravel.

When applying Electronic Control Glass technology partitions in homes and commercial spaces, we are often asked the question "whether they will crack." If you use a Startek brand product, you don't have to worry because it has passed the SGS impact resistance test and will not produce cracks under impact in general usage scenarios (an adult man punching, a 3-year-old kid jogging).
