Car window glass film is a thin film product applied to the inside of car windows, mainly composed of substrate (mostly PET) and coating (such as insulation layer and explosion-proof layer). It can improve the performance of car windows, such as reducing the heat caused by direct sunlight, protecting occupants and items inside the car, and enhancing the safety of car windows. It is one of the car accessories that most car owners choose after purchasing a car.
Characteristics and Applications of Car Window Film
Divided by function, there are four common types of window glass film. One is the sun protection and insulation film, whose core function is to block the entry of solar heat into the car. In summer, it can lower the temperature inside the car, reduce the frequency of air conditioning use, and is suitable for car owners in hot climates; At the same time, focus on blocking ultraviolet rays (especially UV and IR), reducing the damage of ultraviolet rays to the skin of passengers in the car, and preventing the aging and fading of seats and interior due to ultraviolet radiation; The second is explosion-proof film, which has a certain degree of toughness. When the car window glass is accidentally broken, it can stick to the glass fragments, avoiding splashing and injuring people, and has strong safety; The third is privacy film, which has a low light transmittance and makes it difficult to see the inside of the car from outside. It can protect the privacy inside the car. However, it should be noted that different countries have different regulations on car window film. Generally, the light transmittance cannot be lower than 70% (front windshield) and 50% (front side window) to avoid affecting the driving line of sight.
Size and Installation of Car Window Film
The size of the window glass film needs to be adapted to the window size of different car models. Conventional products are mostly rolled, with a common width of 1.52 meters and lengths of 10 meters, 15 meters, and 30 meters. The wholesale size is usually 1.52x30M. If you are interested, you can contact us. Our factory often has inventory and supports 1 roll.
Install a general wet sticker and pay attention to cleaning the car window. Compared to installing the car film, installing the car window film is relatively simple. If it is installed on complex surfaces or edges, a hot press gun can be used to assist with installation.
The Price of Car Window Film
Generally, adhesive car window film is relatively poor, and currently the lowest quality requirement on the market is 1-2 ply dyed film, 1 roll 1.52x30M, 28USD/roll-50USD/roll, excluding transportation. Ceramic film metal film with better insulation effect, 1.52x30m 85USD/roll~300USD/roll, excluding transportation. Explosion proof glass film, generally thickness 2mm-12mil, 1.52x30m 40usd/roll~250usd/roll, excluding transportation. The price of chameleon car window film is relatively higher, 1.52x30M 150USD/roll~350USD/roll, excluding shipping. Mirror glass film, generally 50usd/roll~80usd/roll, excluding transportation, etc. Gradient type also would need higher price, most popular for big car like trucks.
The same series of different VLTs generally have the same price. VLTs are commonly 5%, 10%, 15%, 20%, 35%, 50%, 70%, 75%, 80%, 90%, etc. The lower the VLT, the darker the window film, and the higher the VLT, the more transparent the window film. An error of 0-5% is within the normal range, and some customers may require less than 3%. IRR, UVR, TSER are generally data on thermal insulation effect, with higher values indicating better performance. If you are interested, please feel free to contact us for more detailed information.
Summary
Window glass film is a practical automotive accessory with a wide range of types to meet different needs (such as insulation, explosion-proof, privacy). Its size can adapt to most car models, and its core purpose is to improve the interior environment, protect personnel and interior, and enhance safety. The price range is large, ranging from a few hundred yuan to several thousand yuan, and can be chosen according to budget and demand. However, when making a purchase, it is important to choose products that meet the national light transmittance standards to avoid low-quality films affecting driving safety. It is also recommended to have the film applied in a regular store to ensure the effectiveness of the film (such as no bubbles or corner adhesion) and extend its service life.
FAQ (Frequently Asked Questions)
1. After the window glass film is attached, how long can it be used to open the window?
It is recommended to let it sit for 3-5 days after pasting before opening the window. The film that has just been applied has not yet fully cured, and opening the window too early may cause the film body to shift and the edges to curl, affecting the bonding effect; If it is rainy or humid, it should be extended to 5-7 days to ensure that the adhesive is completely dry.
2. What should be done if there are bubbles or delamination on the window glass film?
If small bubbles (with a diameter less than 5 millimeters) appear within one month after pasting, you can contact the construction store and use specialized tools to squeeze out the air inside the bubbles and re compact them; If the bubbles are large or delamination occurs, especially for membranes that have been used for more than 1 year, it indicates poor membrane quality or improper construction. It is recommended to replace the membrane with a new one to avoid bubbles affecting vision or delamination releasing harmful substances.
3. How to remove the old car window glass film? Can it be torn off by oneself?
I don’t recommend tearing it yourself. It is recommended to go to a professional store, use a hot air gun to heat and soften the backing adhesive, and then slowly peel it off with a special tool, while cleaning the residual adhesive marks, which is both efficient and can protect the glass. If you try it on your own, use a hair dryer or hot press gun to heat it at low temperature and slowly tear it off. When wiping, be careful not to scratch the glass.
