DO Sunroofs have UV protection GV70?
When buying a car, we often pay attention to the core parameters such as the power, interior, and space of the vehicle, but it is easy to ignore a detail closely related to the daily ride experience-the ultraviolet protection ability of the sunroof. Especially for the luxury and comfort SUV, such as the GV70. The sunroof is not only a configuration to improve the lighting and vision in the car, but also a key factor to affect the ride comfort.
Necessity of ultraviolet protection for sunroof
In order to understand the ultraviolet protection ability of the GV70 sunroof, it is first necessary to make clear the harm of ultraviolet rays to the human body and the vehicle interior. Ultraviolet is a kind of electromagnetic wave with a short wavelength, which can be divided into UVA, UVB and UVC according to different wavelengths. Among them, UVA and UVB can penetrate the atmosphere and cause harm to human skin. Long-term exposure may lead to skin aging, sunburn, and even skin cancer. At the same time, ultraviolet rays will accelerate the aging of the vehicle interior, make plastics, leather, and other materials fade and crack, and shorten the service life of the interior.
In order to deal with the harm of ultraviolet rays, automobile sunroofs are usually protected by various technical means. Common protection methods include using anti-ultraviolet glass, adding thermal insulation coating, and equipping with a sunshade curtain. Ultraviolet-proof glass is made by adding special metal oxides, such as iron oxide and titanium oxide, in the glass production process, which can absorb or reflect ultraviolet rays, thus reducing the transmittance of ultraviolet rays. Thermal insulation coating is to spray one or more metal coatings on the glass surface, such as silver and aluminum, which can not only reflect ultraviolet rays, but also effectively block infrared rays and reduce the temperature inside the car. The sunshade curtain directly blocks ultraviolet rays from entering the car through physical shielding, and can also play the role of heat insulation and privacy protection.
Analysis of ultraviolet protection configuration of sunroof
As a luxury medium-sized SUV, the GV70 has made great efforts in sunroof configuration. According to official data, the GV70 is equipped with a large panoramic sunroof, which creates a wide view and a transparent sense of space for the car.
The sunroof of the GV70 is made of UV-proof glass and thermal insulation coating technology. For example, many luxury brand SUV models, such as the BMW X3. Mercedes-Benz GLC, etc., usually have an ultraviolet blocking rate of more than 99%, which can effectively protect passengers and interiors from ultraviolet rays.
In addition, GV70 is equipped with an electric sunshade, which further enhances the ultraviolet protection capability of the sunroof. The electric sunshade can not only close quickly when the sun is strong, but also prevent ultraviolet rays and heat from entering the car. It can also adjust the opening of the sunshade as needed to meet the lighting needs in different scenes. At the same time, the sunshade curtain is usually made of fabric with ultraviolet reflection function, which can further enhance the ultraviolet protection effect.
Protective effect
In addition to analyzing the UV protection ability of the GV70 sunroof from the technical parameters and configuration level, we can also know its real performance through the actual use effect and user feedback. According to the feedback from some GV70 car owners, in the daily use process, the ultraviolet protection effect of the sunroof is obvious. Even in the summer with strong sunshine, the car will not feel obvious ultraviolet radiation, and the skin will not feel burning. At the same time, the aging speed of the interior is relatively slow, and it can still maintain a good state after years of use.
However, some car owners report that the temperature inside the car will still rise after a long period of exposure, especially if the air conditioner is not turned on. This is mainly because although ultraviolet rays carry less heat, infrared rays and visible light can still enter the car through the sunroof glass, resulting in an increase in the temperature inside the car. Therefore, in order to further improve the ride comfort, it is suggested that car owners should use the sunroof together with the air conditioning system and sunshade to achieve the best cooling effect.
Improve the UV protection ability of the GV70 sunroof
Although the sunroof of the GV70 already has certain ultraviolet protection ability, if the owner has higher requirements for ultraviolet protection, the protection effect can be further improved in the following ways:
Professional thermal insulation film: There are many thermal insulation films specially designed for automobile sunroofs on the market. These thermal insulation films not only have a high ultraviolet blocking rate, but also can effectively block infrared rays and visible light and reduce the temperature inside the car. When choosing thermal insulation film, it is recommended to choose products with high brand awareness and guaranteed quality, and to be mounted by professionals.
Use a sunshade: When parking, you can put a sunshade on the sunroof to directly block sunlight from entering the car. Sunshades are usually made of reflective materials, which can reflect most of the sunlight back and reduce the heat accumulation in the car.
Regular maintenance of the sunroof: regularly check the sealing strip and drainage system of the sunroof to ensure that the sunroof is well sealed and prevent rain and dust from entering the car. At the same time, you can also use a special glass cleaner to clean the sunroof glass to maintain the transparency and protective effect of the glass.
FAQ
Q: Is the ultraviolet protection of the GV70 original sunroof enough for daily use?
A: The basic ultraviolet protection of the original sunroof can meet the needs of most daily commuting and short-distance trips. If people are exposed to the sun for a long time or are sensitive to ultraviolet rays, additional protection can be installed to further enhance the effect.
Q: Will the installation of heat insulation film affect the opening and closing of the sunroof?
Answer: As long as the thermal insulation film adapted to the size of the sunroof is selected and mounted by professionals, it will not affect the normal opening and closing of the sunroof at all. The thickness of the regular professional thermal insulation film is appropriate, and the adaptive space of the sunroof will be reserved when mounting, so you don’t have to worry about the problem of being stuck or unable to open and close.
Q: Will the ultraviolet protection ability of the sunroof decrease with use?
A: If you don’t pay attention to daily maintenance, scratches on the sunroof glass and aging of the sealing strip may affect the protective effect to a certain extent. Therefore, regular maintenance of the sunroof and maintenance of the glass and sealing parts can stabilize the protective performance.
