Patio Doors

Patio or sliding doors are becoming more common. While patio doors contain a large glass area, breaking glass is one of the least desirable ways a burglar uses to gain entry. The amount of noise involved in breaking the glass and the potential for suffering an injury, ensures most burglars will look for an easier and safer mode of entry.

Measures should still be enacted to protect the glass areaagainst breakage. The application of an impact-resistant material, such as security film, can be considered. Security film has limitations, but a superior glazing product would be laminated glass, similar to a car windshield. It offers a penetrating resistance other glass products do not possess.

Patio doors can also be defeated by prying the lock, sliding the door open or by lifting the door out of the track. Fortunately, these types of attacks can be prevented. Secondary-locking devices such as pins or "charlie bars" can be used to prevent forcing the door open. Available at most hardware stores, these devices are inexpensive and easily installed.

To prevent the patio door from being lifted out, it is recommended a homeowner use evenly-spaced screws inserted in the upper track of the sliding door. The head of the screws should protrude just enough to allow free movement of the door, but prevent the door from being lifted out of it's tracks.
