4X greater stretch for break-and-entry protection.
Glass is the most vulnerable point in any building. 3M S2400 is a 24-mil polyurethane security film that helps hold broken glass together during forced-entry, smash-and-grab, and blast events — deterring unwanted entry and protecting people from flying glass. Epic installs S2400 exclusively with the Epic Method, our patent-pending structural attachment process, so the film performs as rated under real-world conditions.
