Features

Lanai Doors™ top-hung wood 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. Our wood door and window panels are made in every available wood species by manufacturers located in the pacific northwest and central United States. This allows Lanai Doors to provide a wood folding system that meets your needs rather than you having to compromise your options to a door we manufacture.

Extremely Large Openings and Multiple Configurations

Lanai Doors™ wood folding systems are the largest in the industry and can be configured various ways. The maximum size wood door panel is 4' 3" wide by 13' 1" tall, up to 350 pounds, and up to 2 ¼ inches thick. A single system can be as large as 68 feet wide by 13' 1" tall. In a 68-foot wide system, that would equate to nearly 56 feet of glass – what a view. Lanai Doors™ wood 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. Do not forget to ask about our corner units too.

Standard Pricing

Lanai Doors™ bi-folding 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 you need for a standard priced panel. Lanai Doors™ standard priced wood door and window system includes:

  • Panel up to 36 inches wide and up to 96 inches high
  • Your choice of Red Oak, Superior Alder or Pine
  • Standard outswing threshold with aluminum exterior and wood fir mould interior; Standard inswing all aluminum threshold; Low-rise ADA aluminum threshold; or flush guide for a seamless transition
  • One-lite IG clear tempered (dual glazed) or laminate glass
  • Bronze; Bright Gold; or Brushed Stainless Steel hardware
  • 1 ¾ inch panel thickness and jamb width is 6 9/16 inches

In addition to the Lanai Doors™ standard system, customers have various options for tinted or designer glass, number of lites, almost any wood type 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 we do not require the use of specific installers.

No Sun Exposure Warranty

Lanai Doors™ does not warranty a wood panel from warping which is subject to direct sun exposure. The industry rule of thumb is that a southern and western exposure requires 100 percent overhang (eight foot door requires an eight foot overhang); eastern and northern exposures requires 50 percent overhang.

Not Hurricane Certified

Lanai Doors™ wood bifold door and window systems are built to withstand harsh weather conditions. However, we currently do not have plans to obtain Miami Dade County hurricane certification.

Customize

Lanai Doors™ folding glass walls can be customized to fit the needs of your project. Do you want 3 panels stacking to the left and a swing door to the right, or all of them to the right? Maybe you want a stationary side-lite with 5 folding panels, or a zero post corner unit? If you have an idea, let us know, and we will try to make it happen. The following is a list of some of the many customizations that we can do for you:

  • Vast selection of custom wood species, you name it and we will try to get it
  • Panels sizes up to 4' 3" wide by 13' 1" tall
  • Over 150 different standard configurations (3 left-1 right, 8 right, Inswing, Outswing, etc.)
  • Optional oversized bottom and top rails
  • Multiple threshold types from weather-tight to commercial to seamless
  • Custom glass available, we will work with our suppliers to find the glass that you need for your project

Performance

Lanai Doors wood folding glass doors and windows have been tested in the laboratory. Our wood 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
