Is it necessary to apply window film to cars in summer?

If you are not particularly afraid of sun exposure or have privacy needs, you can skip the film application, as the car will appear exceptionally bright and fresh. Pay attention to the following points when applying film: 1. Infrared radiation from sunlight is the primary source of heat in nature. The main function of high-quality car film is to reflect infrared rays, making the enclosed interior temperature significantly lower than the outside, thereby reducing air conditioning load and saving fuel. 2. Excessive ultraviolet (UV) exposure can burn the skin and cause diseases. Additionally, UV radiation accelerates the aging of various interior components such as the dashboard. Therefore, high-quality car films typically have an extremely high UV blocking rate. 3. For window films, especially those on the front side windows, choose films with a light transmittance of 85% or higher. This helps reduce the intense glare from the headlights of following vehicles reflected in the rearview mirror during night driving, making it much more comfortable for the eyes. 4. In the event that the glass of a car with high-quality film is shattered, the film will hold the broken pieces together, preventing them from flying and causing injury.
I think applying window film to cars in summer is absolutely necessary, as I have personally experienced driving in the southern regions. Without film, the direct sunlight makes the interior feel like a steamer, burning my arms and face red and painful. Turning up the AC leads to a surge in fuel consumption, and the interior materials age faster. After installing a good-quality heat-insulating film, the cabin temperature drops by at least 5 degrees, blocking most of the UV rays, making my skin much safer and driving more comfortable. It also helps a lot with privacy—outsiders can't see inside, giving me more peace of mind when parked. However, it's important to choose reputable brands, as cheap films can bubble and obstruct vision. It's best to have them installed by professionals. In the long run, the savings on AC costs and skincare can make up for the initial investment.
