Does a panoramic sunroof need heat insulation film?

Panoramic sunroofs require heat insulation film. The functions and precautions of applying heat insulation film are as follows: Functions of heat insulation film: Although car sunroofs inherently provide some heat insulation and sun protection, for larger panoramic sunroofs, the overall effect is not very significant. In such cases, if better shading is desired, applying a layer of film is necessary, which also offers some anti-explosion benefits. Precautions for applying heat insulation film: It's important to note that applying film to the sunroof increases the overall thickness of the glass. This tests the quality of the film application process. Poor application can lead to noticeable abnormal noises or even cause the sunroof to get stuck, which can significantly damage the motor. Therefore, it's best to have the film applied by professional technicians.

I just bought a new car last year with a panoramic sunroof, and driving in summer felt like having a mini sun right above my head. Later, a friend suggested applying heat-insulating film, and the difference was remarkable. Now, even in 40-degree heat, after driving for half an hour, the temperature above my head is 7-8 degrees lower than before. I don’t even need to crank up the AC as much, saving some fuel. The best choice is double-layer ceramic film, which offers over 60% heat insulation without affecting light transmission. But be sure to choose reputable brands—some low-quality films start bubbling within six months. Last week at the film shop, I met a Tesla owner who said after applying the film, the UV blocking rate reached 99%, and his wife no longer worries about getting tanned.

Just had a sunroof film installed on the company's new business vehicle. As the seasoned fleet manager, I can responsibly say this investment is worth every penny. Especially since we frequently take long-distance trips—without the film, even with the AC cranked up to max in summer, our backs would still be sweating. The most noticeable improvement after installation is that the car no longer feels like a sauna when entering, and the leather seats won’t scorch your skin. The installer taught me to check the specs: UV rejection should be above 95% to meet standards, while infrared rejection is best around 75%. One crucial tip: avoid washing the car immediately after installation; wait at least three days to let the adhesive fully cure.

As one of the first owners in the car club to install a panoramic sunroof, I recommend you directly apply window film. Initially, I thought the sunshade would be enough, but during summer outings with my kid, they kept complaining about their scalp getting sunburned in the back seat. The most comfortable part after applying the film is driving at dusk—the slanting sunset no longer glares. Choose films with low metal content to avoid affecting mobile phone signals. Don't skimp on price; mid-range films around 2,000 RMB can last five years. At last week's gathering, seven or eight fellow car owners regretted not applying it sooner and have now negotiated a group purchase price together.
