Folding Glass Doors and Windows

Lanai Doors™ top-hung thermally broken aluminum folding door and window systems are the perfect patio door in residential, hospitality and commercial applications. Our systems are installed from the Virgin Islands to the Hawaiian Islands; from The Hamptons to Costa Rica. Lanai Doors™ offers wood, clad, and aluminum folding glass doors to give you more finishing alternatives to work within your contemporary, modern and retro designs. Lanai only uses the highest quality Class 1 clear or bronze anodizing and custom architectural painted finishes to match existing doors and windows.

Title 24 Compliant

Lanai Doors™ has crafted our Thermally Broken Aluminum system and our Wood and Clad folding glass door systems to pass the very stringent energy efficiency requirements of Title 24 for new construction in California. See our performance tab to see if our results meet or exceed your local codes.

Quality; Flexibility; and Creativity

We use various southern California aluminum extruders to manufacture all of our aluminum bifolding system components. We design and maintain our own dies, which allow us to decide when and how we enhance and improve our folding system. As an example of our flexibility, in 2007, based on customer demand, Lanai Doors™ now offers a low-rise threshold. We use the highest quality 6063-T5 architectural aluminum, which has a high degree of resistance to corrosion and clean andozing look.

We also use outside vendors for our wood and clad panels. This gives Lanai Doors™ the greatest flexibility in custom wood species availablility.

Extremely Large Openings and Multiple Configurations

The maximum size folding glass door panel is 4' 3" wide by 13' 1" tall, up to 350 pounds and 2-1/4" thick. A single system can be as large as 68 feet wide by 13 feet tall. Lanai Doors™ folding glass door and window systems can be configured to stack outside or inside your house. You also have the option of any combination of panels stacking either to the left or to the right, neither direction to exceed eight folding panels. These industry leading options allow you to Bring The Outdoors In in a big way.
