The reason for the heat insulation and sunscreen of automobile film mainly comes from the heat insulation layer, not the dyeing layer. Poor quality car film, even if the color is dark, can not play a very good sunscreen effect, so only look at the color, is not reliable.
In fact, the current car windshield has explosion-proof function, can withstand strong impact. Even after a collision, small debris will not harm the driver. The depth of the film does not affect the safety of this aspect.
More importantly, a good car film must also have a good transmittance and clarity. Otherwise, if the visibility of the coated glass is less than 50%, the driving safety will be seriously reduced.
The disadvantage of dark automotive film is that it will reduce the transmittance of the glass and affect the line of sight. In terms of privacy protection, dark film has certain advantages over light film, but in a dim environment, the visual condition is not good, coupled with the influence of black film, the observation of the rearview mirror will become difficult. But the light film obviously has a wider view and is easier to drive. Therefore, in many places, it is stipulated that a triangular window must be set aside for observation
Many car owners stick to the film, mainly because it does bring very obvious benefits. Everyone can consider which kind of film to stick according to their own situation. The market is also full of fake and shoddy products, some of the fake film can not achieve the actual effect, and will backfire, have to identify themselves.
