Glass can become a dangerous material when the unexpected occurs. Accidents happen. Nature presents increased danger such as violent weather, high winds, or earthquakes. Vandalism and hostile acts are an unfortunate reality. Shattering glass or flying shards are a major cause of injury and damage in such events. While all Johnson window films somewhat increase safety when glass is accidentally broken, Safe Plus ™ Security films are specifically designed to provide practical protection from all the hazards above. These films have a thick polymer construction and tough adhesive which bonds to your windows, creating a "safety net" between you and the glass, holding broken shards in place.
