Can the car windshield be left without film?
2 Answers
Car windshields can be left without film, as car window tinting is not mandatory or essential but rather a personal preference. Applying film can reduce exposure to sunlight and UV rays, and the windshield is the primary area where the performance of explosion-proof and heat-insulating films—such as explosion resistance, heat insulation, and anti-glare—is most evident. The car windshield has a laminated interlayer designed for explosion resistance, and modern windshields generally come with UV protection and heat insulation features. The vehicle's windshield is the main source of heat radiation that raises the temperature inside the car. Applying film can relatively improve the driving environment, reduce air conditioning energy consumption, and achieve energy-saving effects.
I've been driving a taxi for almost ten years and never put film on the windshield. Whether to apply it or not mainly depends on your own needs, but I have to clarify the legal requirement: the light transmittance of the front windshield film must exceed 70%. Some people think it can block sunlight and heat, but the actual effect is not as great as imagined. I've driven cars with film, and visibility at night is noticeably worse. On rainy days, when the wipers swipe, it's more prone to glare. If you get a low-quality film, it may bubble up after a couple of years, making it even more troublesome to remove. Nowadays, most car windows come with a built-in UV protection layer. If you're really worried about sun exposure, wearing sunglasses is more effective. Saving a few hundred dollars on film can buy you several tanks of gas.
