Enjoy the Ease of Indoor and Outdoor Living

You can make your patio or backyard an extension of your home with a bi-fold door installation. These entryways help you take advantage of the stunning views around your house. When you open the doors, you can appreciate their ability to meet your needs, whether you want to let fresh air in or create a spacious walkway between your backyard and house.

Bi-fold doors have several panels hinged together that fold in on themselves like an accordion when they open. This stacking feature helps the doors take up less space in the entryway.

Installing a bi-fold door can give your home a unique advantage and help increase your property’s value, whether you are planning to sell your house or improve its curb appeal. The bold design may be attractive to those seeking more contemporary aesthetics.

Every bi-fold door receives careful engineering to ensure homeowners can access products with flexible designs. Our doors have a top-hung design and an integrated multiple-point locking system to keep homes safe while providing a simple and efficient operation. They also have a specifically designed narrow profile so homeowners can maximize their views. You can choose doors with up to seven panels that are 22-feet wide.
