When it comes to security, there are many different options available when it comes to patio doors. Fiberglass is an excellent choice because it's durable and can be repainted or stained. Wood offers warmth but requires more maintenance and protection from environmental concerns. Today's patio doors can be as large as a wall and can be designed to look like real wood. They can be customized with a decorative glass or a custom color, and they can meet the security and architectural needs of any home.

Single-pane glass doors lose more heat than sliding ones. To avoid this problem, invest in a model with multiple layers of glass and low emissivity coating. You should also consider installing a thermal break between the glass panes, which is a plastic insulator. Some patio doors have built-in locking systems, such as deadbolts and security locks. While French doors are typically locked using a standard door lock, you can also purchase an optional deadbolt if you feel more secure.
