When selecting tinting films, it is important to know that heat and UV protection do not depend on the shade, but on the film quality. All Llumar films have the same UV protection degree, 99% but the level of heat protection differs, as each newer generation provides a greater heat protection level, which is especially noticeable in summer heat. Thus Basic films have a lower heat protection level than Standard films and nano-ceramic films, but better specifications than the films of other manufacturers who use older technologies in film production.

When it comes to shade, Black Glass recommends 85% dimming behind the post, corresponding to the shade of factory tinted windows, and 30% at the driver's level, as prescribed by the Law.
