Hello everyone, I'm Xiao Li. Today, I saw a hot list topic, saying that it is Xiaomi SU7's sunscreen and heat insulation "configuration is full", and it is not recommended to paste heat insulation film. I think if the configuration is really full, there is actually no difference between sticking and not sticking, maybe the film you pasted is not as good as the effect of the original car, then it is purely redundant. I bought 4 cars by myself, and after spending money to put heat insulation film on the car a few times, I realized that the water of the heat insulation film was too deep, and most people paid the IQ tax.
The first reason why Xiaomi SU7 is not recommended to paste heat insulation film is that the light transmittance of the front windshield is 71%, and the country has relevant laws and regulations, the light transmittance of the front windshield of the car cannot be less than 70%, so this tells you very clearly, if you stick it again, it will cause the light transmittance of the front windshield to decrease, which does not meet the requirements. But what you may not know is that even if the film that many people paste in the 4S store after buying a car, no matter how dark the color is, it does not have much heat insulation effect, which is purely an explosion-proof effect.
Because the glass of the car window is tempered glass, when it is hit, it will directly burst off in one piece, turning into small pieces of glass and falling everywhere. After the film is pasted, even if the glass bursts off, it is still a complete piece, and it will not fall all at once There are glass slags everywhere, which can protect the people in the car from being scratched by the glass to a certain extent. Why do I tell you that the film we put on the 4S store only has an explosion-proof effect, and the heat insulation effect is very poor? Because I have suffered too many losses when I bought those four cars, and the most loss-making time was the IQ tax paid when changing the windshield.
When I was running at high speed, I was smashed by flying stones when I was running at high speed, and when I changed the glass in the repair shop outside, I chose a film that I thought had a good thermal insulation effect from them, and the cost was more than 300, and you must know that the glass was only more than 400 yuan, and the price of the film was about to catch up with the price of the glass. I am willing to spend this money because I know that if the windshield film is not good, the air conditioning effect will be very poor during driving, especially when the sun is backlit, the sun shining on the windshield is no different from directly in the sun. When the glass store took the sample to me, it was used to open a tungsten lamp, so that I felt the effect through the film, and I was satisfied with it, but I didn't expect to spend 300 yuan and finally paid by mistake, the heat insulation effect was very poor, and it was not as good as the 3M film that I spent 1500 on the whole car in the 4S store when I first bought a car. Speaking of which, let's think about it carefully, I am willing to spend money to buy a good quality heat insulation film, we send a free car film in the 4S store, can the quality be good?
A good film you just paste a windshield will cost more than 2,000, not to mention the whole car has to be pasted, even if the quality is average, it will be hundreds, 4S shop a car to earn that money, it is impossible to give you a good film. The kind of film given by 4 is actually an ordinary dyed film, and you can buy it casually for 10 yuan a meter at a roadside stall. In order to gain your favor and facilitate the transaction, people want you to go back to consume later, so they send you this film. Experienced old drivers basically don't want it, but find acquaintances to spend money on better quality. The film on the Toyota Vios I drove before was pasted in a friend's repair shop, and it only cost a few hundred yuan for the whole sticker except for the front windshield, but it was much better than the more than 300 pieces of glass stickers in the glass shop.
Therefore, if you don't know anyone, or if you haven't found a conscientious store, the film you spend money on may be an IQ tax, and it is better to use a 4S store to send it. After the glass of a car like Xiaomi SU7 has done enough sunscreen and heat insulation treatment, the heat insulation effect itself must be good, and the film you spend money on when you go out may really not be as good as the original car glass.
I didn't know how deep the water was for the film, but after being pitted by the glass shop once, I went to a friend's car repair shop to chat and mention this matter, and I was laughed at before I realized that often this kind of invisible and untouchable thing is the most pitiful. And the bigger the brand of heat insulation film, the more fakes, just like the big brand of engine oil, although it is a penny, but I don't know if I get it in minutes. Finally, I advise everyone to buy a car, if you don't like the film sent by the 4S store, you must go to those regular car beauty shops with a large flow of people to apply the film, don't go my old way to be pitted.
