E+ Aluminum Folding Glass Doors and Windows
Features
Lanai Doors™ top-hung E+ 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. Aluminum is a long-lasting low maintenance non-warping alternative to wood. E+ Aluminum doors and windows give you more finishing alternatives to work within your contemporary, modern and retro designs. Lanai only uses the highest quality anodizing and custom architectural painted finishes to match existing doors and windows. E+ Aluminum doors and windows maximize your view because of the narrow 2-7/8 inch wide stiles and 2-7/8 inch wide rails.
Title 24 Compliant
Lanai Doors™ has crafted this system 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. We use the highest quality 6063-T6 architectural aluminum, which has a high degree of resistance to corrosion and clean anodizing look. The nominal thickness of our profiles is 0.15 inches (almost double the competitors) to reduce deflection. Reducing deflection enhances our systems performance in harsh wind conditions; therefore, increasing the longevity of your patio door.
High Quality Thermal Break
Lanai researched the market for the strongest and most energy efficient thermal breaks to design a system that can hold up to strong wind and keep the heat out or in based on your needs. The pour and debridge technology is state of the art. This technique uses a high end two-part polyurethane polymer that will stand up to hottest and coldest areas of North America. Compared to the competition, our thermal break technology is stronger, more energy efficient, less exposed surface area, and a higher quality look.
Extremely Large Openings and Multiple Configurations
The maximum size E+ aluminum door panel is 45" wide. A single system can be as large as 68 feet wide by 13' 1" tall. Lanai Doors™ E+ aluminum folding 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.
Shipped Broken Down For On-Site Assembly
The frame and door panels are pre-drilled with hardware and weather stripping already attached. The frame is broken down into its four pieces (header, two jambs and threshold) and panels are shipped individually. Lanai Doors™ provides detailed installation guidelines and you are able to use your own experienced installers.
Lanai Doors™ is now Hurricane Certified. Please check out our Hurricane Door and Window page for more information.

Performance
Performance
Lanai Doors™ E+ Aluminum Folding Door & Window Systems :
Lanai Doors E+ aluminum folding glass doors and windows have been laboratory tested in accordance with industry standards. Our aluminum systems have been tested for energy performance, forced entry, wind loads, water tightness, and air infiltration. All of our systems have passed the ASTM forced entry test. There are many variables that enter into testing for energy performance, wind loads, water tightness, and air infiltration; so we have organized most of the information into tables.
Lanai Doors™ is committed to Quality
