How Often Should You Replace Car Glass Film? Do You Know?

How Ofen Should You Replace Car Glass Film?Do You Know? 

Most car owners apply car glass film after purchasing a vehicle. Car glass film serves three main purposes: first, blocking ultraviolet rays; second, enhancing shatter resistance; third, ensuring privacy for passengers. But how long is the service life of car glass film? How often should we replace car glass film? I believe many car owners have no idea. Today we’ll talk about this topic.

First and foremost, the service life of car glass film is closely related to its material and production process. The lifespan of low-quality car glass film and high-quality car glass film can differ by more than ten times. Car glass film is divided into three types based on production processes.

1.Dyed car glass film: Dye is directly coated on the base film or adhesive of car glass film. It is characterized by low price and strong light shading, but it has no heat insulation performance. Dyed car glass film basically fades in about one year, and is prone to blistering after long-term use. After absorbing heat to saturation, it will generate far infrared rays for secondary radiation, which causes greater harm to the human body.

2.Vacuum evaporated car glass film: Metal is heated to vapor at high temperature and evenly coated on the base film of car glass film. Most low-priced metal car glass film common on the market is vacuum evaporated car glass film, with a service life of two to three years.

3.Magnetron sputtered car glass film: It is the best car glass film available on the market at present. For example, multi-layer composite metal car glass film, ceramic car glass film and others all fall into the category of magnetron sputtered car glass film, with a service life of more than 10 years. Merchants offer a warranty of more than five years for this type of car glass film, and of course, the price is not low.

High-quality Window Film Requires No Frequent Replacement

There is no need to replace car glass film frequently if no following conditions occur. Low-quality car glass film usually shows problems in one or two years, such as blistering, cracking, and rippling. High-quality car glass film is generally replaced around the 5th or 6th year. Although the product you buy may have an 8-year, 10-year or even longer warranty, it can be used for more than 5 years in actual application. The service life of car glass film is also greatly related to vehicle use and maintenance. For example, if a car is parked in an underground garage every day and not exposed to the sun, the service life of car glass film will definitely be longer. Repeatedly tearing off and reattaching car glass film will cause damage to the glass, which cannot be avoided even with the highest craftsmanship of the car glass film installer.

Too Many Types Of Car Glass Film On The Market

At present, there are too many types of car glass film on the market, and there are also many unscrupulous merchants. So how can car owners identify high-quality car glass film? Let’s teach you some basic knowledge.

1.Clarity: Regardless of the color depth of car glass film, the clarity of high-quality car glass film at night should be more than 6 meters, while low-quality car glass film will give a hazy feeling.

2.Hand feel: High-quality car glass film feels thick and smooth, while low-quality car glass film feels thin and brittle and is easy to wrinkle.

3.Color: The pigment of high-quality car glass film is integrated into the film, durable and not easy to fade. The pigment of low-quality car glass film is in the adhesive. Scratch the film with your fingernail after tearing off the liner of car glass film, and the color will fall off; the scratched part of the film will become transparent. When the scraper is used to smooth the film during the application process, the color may fall off on its own. This type of car glass film will fade in the same year, and the fading will be more obvious after one year.

4.Blistering: Tear off the plastic liner of car glass film and reattach it; low-quality car glass film will blister, while high-quality car glass film remains intact after reattachment. The transparent heat-insulating and shatter-resistant car glass film for front windshields is evolved from transparent bulletproof film, with a light transmittance of more than 70%.

5.Heat insulation: The quality of car glass film depends on its heat insulation performance, which is difficult to identify only by naked eyes and hand feel. A simple test can be used for comparison: place a piece of glass with car glass film on an iodine-tungsten lamp. High-quality car glass film will make you feel no heat at all when you put your hand near it, while a burning sensation on the hand immediately indicates poor heat insulation performance, meaning it is low-quality car glass film. High-quality car glass film can generally be used normally for 5 to 10 years.
