What are the functions of front windshield film?
3 Answers
The functions of front windshield film include: 1. Sun protection and UV protection: The front windshield has a large heating area and is exposed to more UV radiation. The film can effectively block UV rays, protecting the health of the driver and passengers; 2. Heat insulation: The film can block a portion of the heat; 3. Anti-glare: During the day, the bright sunlight can cause glare, and at night, the strong headlights of oncoming vehicles can also produce dazzling glare, especially when driving on rainy nights when the lights are more chaotic. Front windshield film can effectively reduce this glaring light; 4. Anti-explosion function: Since the front windshield is made of tempered safety glass, if the glass shatters, the film can prevent the fragments from flying, thereby protecting the safety of the driver.
As a rideshare driver, I spend over ten hours in the car every day. Front windshield tinting is particularly practical for someone like me who drives long hours. The most noticeable benefit is the excellent heat insulation in summer—without tint, the steering wheel gets too hot to hold, but with tint, I can reduce the AC by at least two settings. I also highly value the UV blocking feature; during long drives, my left hand doesn’t get two shades darker than my right, and the dashboard doesn’t age or fade as easily. Additionally, anti-glare is crucial for night shifts—it reduces the glare from truck taillights on the highway, making my eyes less prone to fatigue. Privacy is secondary since we’re in the service industry. Although tinting costs a few hundred, I find it well worth the money because it significantly improves driving comfort.
My old car has been running for eight years, and the change after applying window film is quite noticeable. The primary function is heat insulation and energy saving. After being exposed to the scorching summer sun, the interior temperature can be 7-8 degrees lower, and the air conditioning cooling efficiency has improved. The film also blocks UV rays, preventing the plastic parts on the dashboard from discoloring or becoming brittle, and the leather seats haven't cracked. Once, a stone hit the windshield on the road, and if it weren't for the film holding the shattered glass together, the car would have been filled with fragments. Although dark films offer better privacy, it's advisable to choose a lighter shade for the windshield with a light transmittance of over 70% for safety. Remember to opt for reputable brands, as those with metal coatings can interfere with ETC signals. When replacing the film, I realized that cleaning off the adhesive residue is the most laborious part, requiring specialized adhesive removers.
