Double Doors also referred to as French Doors are two doors covering an entry point. One door is usually a functional locking door while the other is a functional dummy door. The term 'French Doors' sounds so much more enticing so I shall refer to French doors that much more.
French doors are a type of hinged door that consists of two doors that open away from each other. French doors are typically made of glass and are designed to allow light and air to flow into a room while also providing access. They are commonly used as entry or patio doors and are popular for their elegant and timeless look.
French doors typically have hinges on either side and are hung within a door frame, allowing them to swing open and closed. They can be opened from the center or from one side, depending on the design. French doors are typically made of wood, fiberglass, or vinyl and can be finished in a variety of colors and styles to match the architectural style of the home.
French doors typically don't have a center post, and instead, they are hinged on either side to the door frame. This can make it easier to open and close them, but it can also present security challenges.
If only secured to each other, French doors can be vulnerable to forced entry. To improve security, it is recommended to install a lock or latch on each door, as well as add additional security measures such as a deadbolt, security bars, or smart locks. It is also important to make sure the hinges are secure and to reinforce the door frame.

French Door and Double Door Security Bolts
French door security bolts are devices designed to add extra security to French doors by securing the doors to the door frame or to each other. Some options include:
Surface-mounted bolts: These bolts attach to the surface of the door and can be manually operated to secure the door in place.
Slide bolts: Similar to surface-mounted bolts, slide bolts are mounted on the inside of the door and slide into a socket in the door frame to secure the door.
Deadbolts: Deadbolts are locks that are installed into the door and door frame to provide added security.
Interlocking bolts: These bolts connect both doors together, making it more difficult for an intruder to separate the doors and gain entry.
Security bars: These are metal bars that can be installed on the outside of the doors to prevent them from being opened from the outside.
Smart locks: These are electronic locks that can be controlled using a smartphone app or a keypad, offering added security and convenience.
How to secure double doors with glass
Double doors with glass can present additional security challenges, as the glass may be vulnerable to breaking. Here are some ways to secure double doors with glass:
Install tempered or laminated glass: Tempered glass is stronger and more resistant to breaking than regular glass, while laminated glass is made of multiple layers of glass that can help prevent shattering if broken.
Add security film: This is a clear film that can be applied to the glass to make it stronger and more resistant to breakage.
Install metal bars or grates: These can be installed on the outside of the doors to provide a barrier between the glass and potential intruders.
Use security mesh or wire: This can be installed on the inside of the doors to help prevent the glass from shattering if broken.
Add a deadbolt or latch: Installing a deadbolt or latch can help prevent the doors from being pried open.
Consider smart locks or alarms: Electronic locks and door alarms can provide added security and alert you if someone is attempting to break in.
It is important to note that while these measures can improve the security of double doors with glass, it is still important to regularly inspect the doors and glass for any signs of wear or damage and make repairs as needed.
