As car sun protection programs continue to evolve, since the 90s, the waistline of the car has been significantly increased, and the size of the four-door windows has also been reduced, thus reducing the damage of the scorching sun to the occupants. In order to better protect from the sun, the car has gradually introduced a special sunshade accessory - sunshade technology.
At first, the visor was external, but it was easily damaged by wind and rain and was difficult to adjust while driving. From 1932 onwards, built-in sun visors became popular, and their design became more flexible, with the ability to turn to the side to block the sunlight from the side, and this dexterous design soon became one of the standard features in cars.
Although some progress has been made in sun protection for automobiles, it has been relatively slow compared to the huge improvements in vehicle power, various comfort configurations such as car air conditioning, seats, etc. However, we didn't give up and looked for new solutions.
In the 90s and the beginning of this century, some models installed curtains in the car in an attempt to solve the problem of sun protection. However, with the implementation of national policies, the light transmittance of automobile windows is strictly required to prevent safety accidents caused by the impact of line of sight, and the regulations require that the light transmittance of the front windshield shall not be less than 70%, and the light transmittance of the side and rear windshields shall not be less than 50%. This makes the traditional method of curtains no longer fit and replaced with tinted glass.
Tinted glass is the addition of colorants to ordinary glass, mostly brown series, green series, blue series, etc. According to the function, it can be divided into privacy glass and heat insulation glass, but its visible light transmittance is still far lower than the requirement of 50%~70%. Therefore, although tinted glass satisfies some of the needs to a certain extent, its limitations remain.
In such a situation, people are turning to another solution – automotive glass film. Automotive glass films offer multiple benefits such as UV protection, thermal insulation, privacy, and added security, as well as enhance the appearance of the car. Nowadays, car wraps in the aftermarket have become one of the most common and popular car services.
Overall, despite the relatively slow pace of development of automotive sun protection programs, people never stop looking for better solutions, and through continuous research and innovation, we believe that the future of automotive sun protection technology will be more complete and provide better protection for drivers and passengers.
