Sliding glass doors sit in a track so the doors can easily glide open and closed, giving you access to the outdoors or letting you open the doors, slide your retractable screens into place, and enjoy an indoor breeze. While most slider doors involve this simple mechanism, the possibilities are virtually endless. Basic sliding doors have only one moving door, but other popular options are:

• Dual sliding doors: With these doors, each one sits on a separate track. That means you can open the left or right door based on your furniture layout, the current activities, or simply your preference.

• Double slider doors with surrounds: If you have an extra wide space for double slider door options, you can install what looks like four patio doors for wall-to-wall views. The central doors can slide open and shut, giving you a grand entrance to your backyard.

• More than two sliding glass doors across multiple tracks: If you do a lot of entertaining, consider having multiple glass doors, each on a separate track. This allows you to slide all the doors to one side, minimizing their footprint and maximizing your space.
