When you think of building security products, you might think of surveillance systems, security guards, metal detectors and card checkers. You probably wouldn't think that the most common type of security systems starts with windows and doors. According to the building.com's article "Doors and Windows Prove Vital to Building Security," doors and windows often play the most integral part of a building's structural security system.

The following is a list of a variety of windows and doors that offer security protection in buildings:

• Radio frequency shiedling doors protect against electronic eavesdropping and data transmission theft. These doors are most often constructed for facilities where sensitive electronic information is stored, like government facilities.
• Acoustical windows and doors are used to prevent audible sound from traveling past the confines of a room and are most commonly found in conference rooms, courtrooms and executive offices.
• Bullet resistant doors and windows are most commonly requested by banks, courtrooms and military installations. These doors and windows are designed to withstand specific durations of assault from small firearms.
• Blast and pressure resistant doors are designed to protect personnel and property from explosions and blasts, and are most commonly found in laboratories, testing rooms and manufacturing plants.

Doors and windows are the simplest yet most important parts of a building's security system. They protect from a wide range of threats including firearms, explosions and other dangers, and also keep audible noises intact. More importantly, windows and doors serve as a building's entry and exit points. So, when not carefully selected and taken into consideration, your building could lack important aspects of security.
