Should the Front Windshield Film Be Applied Inside or Outside?
2 Answers
The front windshield film should be applied inside. The functions of the film include: 1. Blocking heat generated by infrared rays; 2. Filtering ultraviolet rays to prevent skin damage; 3. Enhancing safety and explosion-proofing, as the film has strong tear and puncture resistance; 4. Maintaining privacy and security; 5. Reducing air conditioning load; 6. Minimizing accidents caused by glare. The application method is as follows: 1. Install interior protection for the vehicle; 2. Cut the car sun film according to the window size; 3. Wipe and clean the front and rear windshield glass; 4. Use a heat gun to shape the film; 5. Fine-trim the film after heating is completed.
I've always found the idea of applying film to the front windshield quite interesting. Typically, the film should be applied to the inner side of the glass, not the outer side. If applied on the outside, the film is prone to scratches from rain and gravel, and it can also affect visibility, making the view blurry while driving, which is unacceptable. I remember a friend who tried applying it to the outside himself, and within a few days, the film started bubbling, eventually requiring a costly redo. A professional installer told me that applying it on the inside can block UV rays, reduce heat and noise, protect privacy, and prevent glare from bright lights. Of course, it's crucial to choose high-quality products to avoid issues like bubbling or peeling with inferior films. Regular maintenance is also important—clean the glass gently and avoid using hard objects to scrape it. Over time, experienced drivers realize how essential it is to apply the film correctly—safe and hassle-free. Spending a bit more time finding a reliable installer pays off in the long run.
