The automobile skylight must be covered with film.
The glass used in the automobile skylight is based on the safety standard of the automobile side window glass, that is to say, the tempered glass can be used. Automobile glass is generally divided into two main categories: laminated glass and tempered glass. Front windshield must be laminated glass, which is sandwiched with PVB film in the middle. When hit, the glass fragments will be glued to the film and will not splash. Side window glass safety requirements are low, the use of tempered glass in the impact will produce a large number of debris, although these debris is "obtuse angle", not as sharp as ordinary glass debris, but may hurt people.
