Can the car windshield be left without film?

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.

Having been in the car modification business for so many years, whether to apply a front windshield film depends on the specific situation. Films do have benefits—they block a lot of UV rays, protecting the dashboard from aging, and reduce the air conditioning load in summer. But never go for the cheap options—those two or three hundred yuan films from roadside shops are a no-go. Not only is their light transmittance poor, but they also start bubbling within a year or so. If you decide to apply one, opt for a reputable brand’s ceramic film and have it installed by a professional. That said, I don’t have one on my own car—clear visibility is crucial on long drives, especially on mountain roads, where even a slight glare could lead to misjudgment.

As a mom of two, practicality and safety are my top priorities when driving. I have a lot to say about front windshield tinting—I followed the trend and got my windows tinted the first couple of years, only to find it made things harder with kids. Since children sit low in their car seats, the tint made the interior darker, making it difficult to see what was happening in the backseat when they cried or got sick. Sure, it reduced glare in summer, but later I bought sunshades that worked just as well. The most annoying part was last year’s vehicle inspection—the tint was too dark and nearly failed. Now I’ve ditched the tint altogether. Driving at night or in the rain is so much clearer, and I feel way safer. That’s a hundred times more important than sun protection.

Having worked in the auto repair industry for 15 years, I advise against casually applying film to the windshield. Many car owners don't realize that when a windshield cracks and needs replacement, the money spent on the film goes straight down the drain. Last week, I just helped a customer remove a bubbling low-quality film, and the adhesive residue left on the glass was particularly troublesome to clean. Films can also easily cause optical distortion, especially on curved windshields. If you must apply one, remember these three points: the light transmittance must meet standards, find a professional shop with a dust-free workshop, and keep the warranty card. But honestly, most mid-to-high-end cars now come with factory-installed glass that already has heat insulation, making the film redundant and a waste of money.

Living in an area with strong UV rays, I've compared the effects of applying or not applying a front windshield film. Cars with high-transparency films showed dashboard temperatures about 5 degrees lower than those without, and the burning sensation on arms under direct sunlight was noticeably reduced. However, the trade-off was approximately 20% reduced night vision, requiring extra caution while driving. After observing a car with film applied for five years, I noticed the edges of the film tend to turn purple and discolor, which can be unbearable for perfectionists. Without film, monthly application of glass coating agents provides good hydrophobicity without affecting light transmission. My current approach is applying sun protection film in spring and summer, while enjoying unobstructed visibility in autumn and winter—flexibly adjusting to what suits me best.
