Are French Patio Doors More Secure Than Sliding Doors?

The right patio door enhances the appearance of your home and provides a transition between your exterior and interior spaces. Just like windows, a good patio door also protects you from the weather as well as secures your home. Two of the most preferred type of patio doors are the sliding door and the French door.

If you are planning to have door and window replacement, you should consider both style and security. Perhaps you have heard that French patio doors are more secure than sliding ones, and vice versa. Renewal by Andersen of Long Island explores the answers in this post.

Which Are More Secure?

Sliding doors that had been made years ago can be pushed up from the outside and that could dislodge the locking mechanism easily. However, door and window replacement experts hold that sliding door designs have been improved so this would not happen unless you have an old sliding door.

That said, French doors without a sophisticated locking system can also be easily opened from outside. With a proper tool, the flush bolt on the top and bottom of the passive leaf can be opened from the outside, and the door can be pushed open even with the deadbolt locked.

Dependable Locking System

No door is 100% foolproof, but a door with a dependable locking system can be harder to break into. Renewal by Andersen French doors use a five-point locking system. Lifting the active door’s handle will release two hooks that will grab the top and bottom of the passive door. Lifting the passive door’s handle will cause pins on the top and bottom to stick out and lock the door.

For sliding doors, Renewal by Andersen uses a reach-out locking system which snugly pulls the door panel into the jamb. An optional auxiliary foot lock mechanism can be added to further keep the door secure.

"I was very impressed with Renewal by Andersen. They showed up in time and we received several follow up phone calls as the installation was being done as well as the sales representative stopping by to check in on the installation. The delivery/ installer was very professional. I would highly recommend Renewal By Andersen."
