Protective (impact-resistant) films are used to increase the level of security and ensure the preservation of property. They are used as an alternative to gratings, which makes it possible to place objects under protection. Armoring films on windows are usually installed where there is no need to use expensive armored glass or other mechanical protective means. Armored (protective) films are irreplaceable where there is a direct threat of explosions and consequences caused by the resulting fragments. Booking the windows of buildings allows you to refuse to install bars and protects against penetration into the premises. For example, if a stone or brick is thrown at your window, the glass may crack, but the fragments will be retained by the film and you will not need an urgent replacement of the double-glazed window. It is not so easy to break into a building with an armoring film, and even with the use of special tools it will take a long time (which depends on the protection class (glass armoring) and physical abilities of the attacker).
