What Is the Most Secure Type of Patio Door?

Securing a Sliding Patio Door

• Multi-point locking system that engages at multiple points along the frame
• Anti-lift hardware that prevents the panel from being lifted off the track from outside
• A secondary security bar or rod placed in the track as a backup
• Laminated or tempered glass that resists breakage

Securing a French Patio Door

• Multi-point locking system (deadbolt at multiple heights along the door)
• Hinge-side security pins that prevent forced entry even if the hinge is compromised
• Reinforced strike plates embedded in the frame

Which Is More Secure Overall?

French patio doors with multi-point locks are generally considered slightly more secure because they lock the same way as a standard entry door — with a deadbolt — rather than relying on a latch mechanism. That said, a quality sliding patio door with proper multi-point locking and anti-lift hardware is more than adequate for residential security.
