How Often Should Car Window Tint Be Replaced?
2 Answers
Replace it approximately every 3 years. The replacement of car window tint depends on the degree of wear. Generally, it takes about 3 years. Most car window glass in the Chinese market is just ordinary glass or coated glass, with UV blocking rates of 19% and 37% respectively. More extended information is as follows: 1. Use tint film to compensate for the shortcomings of the car windows themselves: Car glass alone cannot meet the daily needs of heat insulation and UV protection, which is why tint film is used to improve the inherent deficiencies of car windows. Even for more expensive imported cars, whether to achieve good heat insulation and UV protection effects or to ensure a healthy driving life for yourself and your family, it is best to apply a layer of car window tint. 2. The functions of car window tint: It refers to the film applied to the surface of car glass, commonly known as explosion-proof film. In addition to heat and light insulation, it also has explosion-proof functions. High-quality explosion-proof film uses special polyester film as the base material, which itself has strong toughness and is combined with special pressure-sensitive adhesive. In case of an accident, the glass will crack but remain adhered by the film, preventing shards from flying and causing injury. Car explosion-proof film also has one-way visibility and reduces glare. Since its introduction, car window tint has gone through four stages: dyed film, metal reflective film, heat-absorbing film, and intelligent spectral selection film.
I've been driving for over a decade, and window tinting is quite common. My first car had a standard film, which started bubbling and fading severely after about three years, reducing its heat insulation in summer and forcing me to crank up the AC. Later, I switched to a ceramic film, which is of better quality and has lasted five years so far. The technician advised that replacement timing mainly depends on the film's quality and usage habits; if you live in a hot area or frequently park in direct sunlight, you might need to replace it every 3-5 years, whereas high-quality films can last up to 8 years. Don't just judge by appearance—if heat insulation deteriorates or visibility becomes blurry, it's time for a change. Avoid scratching with hard objects or using harsh chemical cleaners, and regular inspections can save you the hassle of premature replacement. Remember, good films may be expensive, but they save repair costs in the long run—don't skimp and waste money.
