Conventional window glass was not designed to resist windblown debris, earthquakes, explosions and terrorist attacks. Subject to such stresses, existing glass often breaks into lethal shards to be hurled from the window frame endangering school building occupants and passersby. Broken glass causes property damage that would not have occurred had the glass remained in its frame. Security window film can improve the ability of existing glass to mitigate the impact of explosive force and windblown debris. The primary function of security film is to hold glass intact in the event of it being broken, preventing glass from becoming lethal flying projectiles. In some cases, the glass may shatter but remain intact.
