For a burglar to break into a home through a security double glazing window, they will have to break the glass. This is the last thing that they are going to want to do when trying to quietly break into a home. If they do break the glass, it will alert those in the home, or anyone in the nearby neighbourhood, bringing a lot of attention to the area of the crime.

Another deterrent that secure double glazing windows bring is the increased chance of injury. Not only this but breaking secure windows will scatter broken glass at the scene, which can capture small pieces of hair and blood. This is extremely useful for a forensic investigation in positively identifying the intruder.

Security double glazing is also generally more durable, and while it is still a glass window, it’s much stronger than a single glazing window. The force of a blunt object on the first pane of glass is unlikely to break the second, causing the burglar to have to hit it multiple times to break it.
