How Long Does Window Tint Film Generally Last?
2 Answers
Window tint film generally lasts for more than five years. The specifics are as follows: 1. Dyed film: Absorbs heat but does not block it, with a short lifespan of about 1 year. 2. Vacuum thermal evaporation film: Poor clarity, severe reflection, lifespan of 2-3 years. 3. Multi-layer magnetron sputtering film: High clarity, stable heat insulation, lifespan of over 5 years. Information about window tint film is as follows: 1. Window tint film: Also known as heat insulation film, in modern production technology, it is often made by vacuum deposition or magnetron sputtering technology to create multi-layered, dense metal films of aluminum, gold, copper, silver, etc., for high heat insulation. 2. Heat insulation principle: For films exposed to strong light and heat from a lamp, the darker the color, the better it can block and absorb the heat emitted by the lamp.
I've worked in auto repair shops for twenty years, and typically, window films last about five to six years. Some regular customers park their cars in the sun all day, where UV rays and high temperatures cause the film to fade, bubble, and crack, affecting visibility and heat insulation. Cheap, low-quality films might only last three years, while expensive ceramic films can endure seven or eight. It's best to regularly check the film's clarity and replace it before it turns purple, or else the summer heat will pour into the car, making the AC work in vain. Avoid using rough cloths to clean windows—just use soapy water to prevent scratches and extend the film's lifespan. In short, choosing a reputable brand and careful maintenance are key.
