Safety window films are most commonly used to strengthen glass and contain fragments in the event of accidental breakage. Primary areas to consider are doorways with glass or windows that may be vulnerable to accidental or intentional breakage. Safety window films are designed to contain all or most of the glass fragments thus preventing injury or contamination (in the case of food manufacturing). The recommended thickness of the Safety window film will depend on the desired level of protection. For example; a food processing plant should use the highest strength window film available (7mil with a break strength of no less than 110 lbs./sq.in.) which will ensure the best protection possible. The window film should be installed on the side of the glass where fragments are to be contained. Optionally, the window film can be installed on both sides of the glass which would result in a much higher retention of glass fragments. Also, it is recommended to apply a bead of silicone around the edges where the window film meets the frame.
