Wrapping the car is the top priority for the car owner after picking up the car. Among them, the front windshield film is related to the driving experience and driving safety of the owner, and occupies a particularly important position in the vehicle window film mounting.
In general, the front windshield film "shoulders" the three major functions of heat insulation, sun protection, and anti-glare
1. Thermal insulation - closely related to body comfort.
The front windshield is not only large in area, but also has a large inclination angle, and about 40-60% of the heat of the whole vehicle is penetrated through the front windshield, so it is necessary to install high-quality front windshield film to achieve high heat insulation. Especially in hot weather, the sun is exposed to the sun, and the temperature in the car is too high, which is easy to cause psychological and physiological signs such as mental exhaustion and irritability, which affects driving safety.
2. Sunscreen - let people and vehicles get corresponding protection.
Ultraviolet rays exist throughout the year, and the damage to the human body is mainly reflected in the **. Among them, long-wave ultraviolet rays can easily penetrate the dermis, causing roughness, blackening, aging and even cancer. Practice has proved that after the front windshield is covered with film (the ultraviolet blocking rate is greater than 99%), it can effectively protect the driver and passengers and the car interior, avoid damage due to ultraviolet radiation, and escort health.
3. Anti-glare - further improve the safety of driving.
The front windshield is an important "field of vision" for the driver to observe the outside world, and the importance of its clarity is undeniable. According to the provisions of the safety standards for automobile glass in the "Technical Conditions for Motor Vehicle Operation Safety", the visible light projection ratio of the front windshield and the glass other than the windshield for the driver's vision area is not allowed to be less than 70%. The high-quality front windshield film can reduce the dazzling glare during driving, create a good driving vision for the driver, and reduce the occurrence of accidents.
Of course, you can't afford to lose sight of one or the other when it comes to filming. Most car owners pay more attention to the front windshield with a wide glass area, but ignore the front side window of the main driver's seat. According to a survey, the average time that modern people stay in the car for about 8-12 working years in their lives is about 8-12 working years, and the main driver's seat, as the core position in the car, has more stringent requirements for the three performance requirements of the front side window film
1. Stronger demand for heat insulation: the main driver's seat is close to the front gear, and the perceived temperature will be higher than that of the rear row;
2. Higher requirements for clarity: reversing and changing lanes will look at the rearview mirror, and the clarity of vision is very important;
3. Stricter requirements for visible light reflection: the larger central control screen will be reflected at night, which will affect driving safety, so the front side window also needs to maintain a low visible light reflectivity.
Obviously, the front windshield film and the front side window film need to be applied together. So, what kind of window film combination is more suitable and practical?
At present, the mainstream collocation method is as follows: top front windshield window film + front side window film on demand. Taking new energy vehicles as an example, due to the wide area of the front windshield, it is necessary to choose a window film with strong thermal insulation performance, and other parts can meet the needs of new energy vehicles, such as "Weigu VK70 front windshield film + KC35 KC20 side window film", which is a popular combination that new energy vehicle owners like at present, and better interprets high practicability.
VK70 front film is the flagship window film product of VK, which is known as the "double crown of heat insulation and clarity". The product adopts advanced magnetron sputtering technology, which evenly sprays gold, silver and indium oxide on the high-specification PET substrate, uses the principle of reflecting infrared rays to achieve long-term thermal insulation, and blocks ultraviolet rays, filters a large number of dazzling glare, and protects the health of drivers and passengers. In addition, its outstanding performance can reflect a certain two-way effect, not only to protect the comfort of drivers and passengers in hot or sunny weather, but also to prevent the heat of the interior heating through the window conduction and loss in the harsh winter, and maintain the temperature in the car.
The V&G KC series is specially designed for new energy vehicles, using multi-layer nano-ceramic technology, with a total infrared blocking rate of up to 64%. The "strong combination" with VK70 front windshield film has a UV blocking rate of 99%, which ensures the normal operation of the automatic assisted driving system of new energy vehicles while efficiently insulating heat and sun, and the signal is sufficient to gallop at any time. Similarly, the selection of the industry's highest-grade PET substrate with low reflectivity also provides the owner with a high-definition driving vision (clear at night, rainy days, and fog).
The purpose of installing car window film is to reduce the discomfort caused by light and heat, as well as to ensure driving safety. Among them, the front windshield and front side window film is the top priority, paste a good film, get twice the result with half the effort, comfortable and safe all the way.
