Folding & Bifold Patio Doors

Open Your Home to the Outdoors

Folding patio doors (also called bifold, accordion, or multi-fold doors) consist of multiple panels that fold and stack against one another, creating an expansive opening that can span 20 feet or more. When closed, they provide a stunning glass wall; when open, your indoor and outdoor spaces become one.

How Folding Doors Work

Panels are connected by hinges and glide along a top and bottom track. As you open the door, panels fold accordion-style and stack neatly to one or both sides. Most systems include one "traffic door" that operates independently for everyday use without opening the entire system.

Benefits of Folding Patio Doors

• Dramatic visual impact: Floor-to-ceiling glass creates stunning views
• Indoor-outdoor living: Seamless transition to decks and patios
• Natural light: Expansive glass floods interiors with daylight
• Flexible opening: Open partially or fully depending on needs
• Entertainment-ready: Perfect for hosting and outdoor dining
• Home value: Premium feature that increases property appeal
