Sliding glass windows or doors are commonplace in any modern home, especially when they are set up near a patio or the dining room. The big problem, though, is that they are vulnerable to breakage and need to have security window film installed.
A case for installing security film for windows and doors requires understanding how intruders think and plan when they usually strike. A careful analysis of your sliding glass doors and windows will show you how intruders can use them as points of entry. General wisdom states that all it takes for the suspects to get in is to smash a glass panel and gain access to the lock that way.
Some preferred security film products are meant to keep the cohesion of the glass under external induced forces. This is done by applying the entire sheet over both sides of a glass panel, where the transparent sheets limit the spread of the cracks from the point of impact.
Setting up window film has its advantages that also become apparent when the sliding-glass window or door has additional features to complicate break-ins at the attempted point of entry. You can start by setting up a charley bar over an inward track of the window to prevent it from opening fully.
