The coating process plays a crucial role in determining the insulation performance of window films. In summer, even a thin layer of thermal insulation film can make a big difference. It not only helps block the intense sunlight but also provides UV protection, keeping your car cooler and more comfortable. Experts suggest that heat insulation is one of the main reasons why many people choose to install window films. Along with this, factors like light transmittance and UV resistance are also important for consumers to consider. However, there are several common misconceptions about thermal insulation films that many people still believe in.
When it comes to car window films, there are different areas to consider, such as the front and rear windshields, as well as the side windows. The front windshield is the most critical because of strict traffic regulations. According to the Ministry of Public Security, the light transmittance of the front windshield must be above 70% to ensure safe driving visibility. Dark films on the front windshield are not recommended, as they can reduce driver visibility and create safety risks. Additionally, when choosing the UV protection level, higher is generally better, as it helps protect the dashboard and interior from sun damage, which can cause premature aging over time.
For the side windows, the film should not interfere with the driver’s ability to see through the rearview mirror. This allows for more flexibility in choosing colors and styles. Many car owners prefer blue or other colored films for aesthetic purposes, as long as they meet safety standards.
It's also worth noting that the thermal insulation performance of a film isn’t directly related to how dark the color is. Instead, the quality of the coating process is the key factor. A higher insulation rate means the film reflects more heat. Most high-quality films on the market offer around 60% insulation, which is considered excellent. If a product claims to have an insulation rate of 80% or even 90%, it's wise to be cautious and verify its authenticity before purchasing.
If you have a GPS navigation system installed, it's best to go with a non-metallic film. Many popular films on the market contain metal layers, which can interfere with GPS signals and affect navigation accuracy.
Installing window film is a straightforward process, though it requires attention to detail. The steps typically include covering the area with towels to keep it clean, cleaning the glass thoroughly, applying the film, shaping it to fit the window, trimming the edges, cleaning the inside, sealing the film, using a hair dryer to remove bubbles, and finally ensuring everything looks smooth and professional. If the result isn't satisfactory, don't hesitate to ask the installer to redo it. A properly applied film will provide the best protection for your car's windows and enhance your overall driving experience.
