Over the past 20 years, 3M Safety and Security Films have been blast tested by various private and government agencies from Australia to England. Windows treated with these films have been subjected to a variety of close range explosive charges, including TNT, pipe bombs, molotov cocktails and more. In test after test, the protective film has demonstrated the ability to retain shattered glass, even when the entire window has been blown out of its frame. These tests have concluded that 3M Safety and Security Film significantly reduces the potential of glass cut injuries. In this day and age, it seems no building is immune to the threat of terrorism. While heightened security cannot always prevent a building from becoming a target of a blast, precautionary measures such as the installation of 3M Safety and Security Window Film can work to minimize the resulting damage. When you buy 3M Safety and Security Window Films, you are backed by the resources of one of the largest and most respected companies in the world.
