Is the car glass film inside or outside?

After buying a new car, many people's first choice is to apply film to the vehicle. There are three main functions of automobile window film. The first is thermal insulation and ultraviolet insulation.

Today's car window films have a good function of insulating heat and ultraviolet rays. Reduce the amount of heat generated by the sun shining on the window glass in summer and the damage to the human body caused by ultraviolet rays passing through the glass.

Another important function of the automotive glass film is explosion-proof, when the glass explodes spontaneously or bursts by external force, the glass film can stick to the glass fragments to avoid secondary injury to passengers and improve safety.

The third point is to protect privacy, car glass is generally transparent when leaving the factory, in order to protect privacy, you can choose to paste dark window glass film, which plays a role in protecting privacy in the car.

In general, car wraps are attached to the inside of the glass. In order to avoid damage to the film from the external environment. If the front windshield film is attached to the outside of the glass, the film and wipers will cause scratches and damage to the front windshield film.

Other glass films, if pasted on the outside, rain or wind and sand will continue to invade the film, affecting the effect of the film, and it will also damage the film during the car washing process.

The car film is to be attached to the inside of the car glass, because the inside will not be exposed to wind and rain, and the aging will be slower, so as to prolong the service life; At the same time, the film will not be subject to too much external interference during the use of the film, will not be damaged by hanging, will not experience wind and rain, the adhesive will be more firm, and there will be no corners and other conditions.

Extended Materials. There are 7 benefits of car glass film:

1. Heat insulation and sun protection. The film is a good barrier to a large amount of heat generated by infrared rays.

2. Ultraviolet insulation. The medium and long waves of ultraviolet rays can penetrate very thick glass, and most of the ultraviolet rays can be blocked by applying a heat insulation film. Preventing ** injuries can also reduce the aging of car interiors.

3. Safety and explosion-proof. The base layer of the film is polyester film, which has the function of being very tear-resistant and anti-breakdown, and the adhesive layer of the film can prevent the glass from accidentally breaking the glass and causing damage to the driver and passengers.

4. Create a private space. After choosing the right variety and applying the film, it is usually difficult to see the inside of the car from the outside of the car, while the outside of the car can be seen clearly from the inside of the car, retaining privacy and security.

5. Reduce air conditioning and save consumption. The loss of refrigeration capacity of the air conditioner can be compensated for by attaching a heat insulation film, which can instantly reduce the temperature in the car and achieve a certain degree of fuel saving.

6. Increase aesthetics. According to personal preference, the car can be personalized and beautiful through the film.

7. Anti-glare. Reduce accidents caused by glare.

We generally stick it on the inside, look.

The car glass film is pasted inside, because the film is pasted on the inside, so as to play a better explosion-proof effectFor example, when the glass of the vehicle is damaged for some reason, it will be due to the factor of glass film, so as to avoid causing greater damage to the people in the car. If it is pasted outside, it will definitely shorten the use time of the car glass film, and if it is pasted on you, it can also avoid the wind-based Zen blowing rain and prolong the service life.

The precautions for car film are as follows:

1. If you want to apply the film to the car, you must go to a regular institution to operate, so as to ensure the effect of the film and prolong the use time of the film.

2. When the car film is applied to the car, the car can not be washed within three days, otherwise it is easy to cause the film to fall off.

3. When the car film is too early, it usually takes more than 24 hours for summer, and it may take 48 to 72 hours if it is a cold winter. If you raise or lower the window too early, it may cause the film to shift.

4. When air bubbles are found after the film, it is recommended to go to the car beauty shop for treatment within 24 hours.

Car wrap is attached to the inside of the glass.

The main reason is to avoid damage to the film from the external environment.

Car film is to paste a film-like object on the front and rear windshields, side windows and sunroofs of the vehicle, and this film-like object is also called sun film or heat insulation film.

An important function of the automotive glass film is explosion-proof, when the glass self-explosion or external force impact burst, the glass film can stick to the glass fragments, avoid secondary injury to passengers, and improve safety. Automotive heat insulation films are usually around the same thickness.

The glass film is to be attached to the inside of the car glass. Because it is not easy to be scratched when attached to it, it can also play a role in protecting the people in the car. At the same time, sticking it inside can also prolong the service life, and at the same time, the film will not be subject to too much external interference during use, and will not experience wind and rain, and the sticking will be firmer, and there will be no corners and other conditions.

Car film is to paste a layer of film-like objects on the front and rear windshields, side windows and sunroofs of vehicles, and this film-like object is also called solar film or explosion-proof heat insulation film. Its function is mainly to block ultraviolet rays, block part of the heat and prevent the sudden burst of glass caused by injuries, and at the same time, according to the one-way perspective performance of the solar film, to achieve the purpose of protecting the privacy of the brothers. In addition, it can also reduce damage caused by UV exposure to the contents of the vehicle and personnel, which in some ways can save fuel consumption.

The former windshield as an example, because the film is attached to the inside of the car glass, so the wiper will definitely not hurt the glass film, and because the windshield wiper is on the outside, if the car film is attached to the outside, then the windshield needs to be removed for operation, which is too cumbersome and dangerous, and it is possible to damage the car glass if you are not careful. In addition, the car film is easy to age in the face of wind and sun on the outside, reducing the effect of explosion-proof heat insulation, therefore, the car film will be pasted inside.

The car glass film is generally attached to the inside:

1. Be sure to cover the necessary parts of the car before applying the film to prevent liquid from seeping in. The sprayed cleaning fluid and lubricating fluid can affect the interior electronics and interior seats.

2. Inside the window before the film. Exterior surfaces are cleaned (with a focus on interior surfaces and glass sealant areas). This is mainly to eliminate the dirt or other object construction quality problems between the heat insulation film and the window glass after the film, and ensure that the film and glass can be perfectly combined;

3. Pre-cutting of the film. Use a ruler to measure the size of the front and rear windshields, and cut the membrane rubber according to the measured size;

4. Spray installation fluid. It can avoid dust spots and reduce corrosion on the edges, obtain the viscosity required for shaping and better application results;

5. Dry roasting, wet roasting shaping. First, the heat insulation film is dry baked, so that the heat insulation Liang Xian Li film can be fully pre-shrunk. In order to further improve the applicability of the heat insulation film, it is also necessary to wet bake and shape the heat insulation film;

6. Extrude the installation fluid. In the process of using the wiper to remove the installation fluid, try to scrape off the installation fluid between the heat insulation film and the car window glass, which can reduce the drying time of the heat insulation film and obtain better bonding effect, overall performance and visual effect;

7. Check after pasting. Look at the entire insulation film for dust and air bubbles, see if the corners are firmly glued, and sit in the car to see if there are any areas that affect the view (especially the front and side windshields). After the film, it is recommended not to raise or lower the glass arbitrarily within 48 hours.
