Is it necessary to apply film to the front windshield of a sedan?

Applying film to the front windshield of a sedan depends on personal needs. Below are the pros and cons of applying film to the front windshield of a sedan: 1. Advantages of applying film to the front windshield of a sedan: 1. UV protection: This is essentially the biggest selling point of front windshield films. High-quality films can block up to 99% of UV rays, significantly reducing damage to the car's dashboard, center console, and various interior decorations, preventing aging of car instruments and fading of interior decor. 2. Anti-explosion: High-quality front windshield films generally have anti-explosion functions, preventing the windshield from shattering in emergencies, thereby avoiding secondary injuries to the driver and front-seat passengers. 3. Anti-glare: Front windshield films can effectively reduce the visual stimulation caused by harsh glare, alleviating eye fatigue from prolonged driving and improving driving safety. 2. Disadvantages of applying film to the front windshield of a sedan: 1. Reduced light transmittance: Traffic laws and regulations require that the light transmittance of vehicle glass should generally be above 70%. The front windshield itself has a light transmittance of about 75%, which means the film must have a light transmittance of over 90% to comply with traffic regulations. Otherwise, drivers may face penalties for violations. However, films with over 90% light transmittance are relatively rare in the market. 2. High cost: Currently, high-quality front windshield films from reputable brands are generally expensive, which often deters many drivers. 3. Poor-quality films obstruct vision: The front windshield films are the most expensive in the car market, leading to the emergence of manufacturers producing substandard films under the guise of international brands. Applying such films to the front windshield not only fails to provide the intended benefits but can also interfere with the driver's vision, increasing the risk of traffic accidents.
