Styles and Designs

Choose a style and design for your residential patio door that fits your home and desired function:

1. Sliding Patio Doors

Come with at least 2 panels: one slides and one is stationary. They don’t swing out, making them sleek for small spaces.

2. Swinging

Operate similarly to hinged doors, swinging either inward or outward.

  • Fiberglass—A low maintenance, durable door that withstands weather.
  • Wood—A rich, authentic wood door that adds beauty to your home. Requires more upkeep than other options.
  • Steel—A low maintenance, super strong door that boosts your home security. Treated to resist rust and moisture.
  • Vinyl—An affordable, durable, energy efficient door.

Handles and hinges—in a variety of finishes

  • Chrome
  • Oil rubbed bronze
  • Brushed satin nickel
