Is it better to choose a metal film or a ceramic film for car tinting?

1. In terms of heat insulation performance, metal films significantly outperform ceramic films. Metal films are made from various precious metals using advanced processes like magnetron sputtering, allowing for selective passage of light. Conversely, ceramic films, composed of ceramic materials, may produce secondary heat radiation when the ceramic layer reaches thermal saturation. Consequently, metal films provide superior heat insulation compared to ceramic films.

2. From the perspective of light transmission, metal films tend to have darker colors, resulting in reduced transparency but offering better privacy. Ceramic films, on the other hand, feature lighter colors, allowing for more light transmission but providing somewhat weaker privacy. For car owners who frequently drive at night, opting for ceramic films can be a practical choice, as it aids in better visibility during nighttime road conditions.
