Features

Lanai Doors™ top-hung aluminum folding door and window systems are a great alternative to traditional French doors, sliders, pocket doors and pass-thru windows 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. Aluminum doors and windows give you more finishing alternatives with the retro look of clear anodized or the warmth of bronze anodized; and painted finish to match existing wood, clad or vinyl doors and windows. Aluminum doors and windows maximize your view when the system is locked down because of the narrow 3 inch wide styles and 3 ½ inch wide rails.

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 aluminum, commonly referred to as the architectural alloy, which has a high degree of resistance to corrosion.

Extremely Large Openings and Multiple Configurations

The maximum size aluminum door panel is 4' 3" wide by 13' 1" tall, up to 350 pounds, and 1-¾" thick. A single system can be as large as 68 feet wide by 13 feet tall. With a 4' 3" wide by 13' 1" tall panel, 84 percent of each door would be made up of glass. In a 68 foot wide system, that would equate to nearly 60 feet of glass – what a view. Lanai Doors™ 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.

Standard Pricing

Lanai Doors™ bi-folding glass systems are priced on a per panel basis and are built to either your actual rough opening dimensions, or we will calculate for you the size of rough opening required for a panel size of your choice. Lanai Doors™ standard priced aluminum door and window system includes:

  • Panel up to 36 inches wide and up to 96 inches high
  • Clear / bronze anodized or 5 standard paint colors
  • Standard / low-rise aluminum threshold / flush guide for a seamless transition
  • One-lite IG clear tempered (dual glazed) or laminate glass
  • Stainless Steel / Bright Gold / Bronze Hardware

In addition to the Lanai Doors™ standard system, customers have various tinted and designer glass options, kickplates, true divided lites, custom paint, and panels up to 51 inches wide and up to 13 feet tall. We build our folding systems to your custom order!

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 Press Releases and our Hurricane Door and Window Pages for more information.

Not Thermally Broken

Lanai Doors™ aluminum bifold door and window extruded aluminum systems are contiguous aluminum and are not thermally broken.

Performance

Lanai Doors™ Aluminum Folding Door & Window Systems :

Lanai Doors 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.
