A Smarter Choice for Large Openings
Lanai Doors™ top-hung aluminum folding door and window systems are a premium alternative to traditional French doors, sliding glass doors, pocket doors, and pass-thru windows. Perfect for residential, hospitality, and commercial projects, Lanai Doors are designed for durability, low maintenance, and architectural flexibility.
Our systems are trusted worldwide, with installations spanning from the Virgin Islands to Hawaii, and from The Hamptons to Costa Rica. Whether in a tropical climate, coastal environment, or urban setting, Lanai Doors provide lasting performance and design flexibility.
Beauty in Slim Design
One of the hallmarks of a Lanai Door system is its narrow sightlines:
-
3-inch-wide stiles and 3 ½-inch-wide rails maximize natural light.
-
Large glass areas provide expansive, unobstructed views.
-
Finish options include:
-
Clear anodized for a retro-modern look
-
Bronze anodized for a warm, rich tone
-
Painted finishes to match wood, clad, or vinyl systems
-
Lanai aluminum doors and windows balance strength, beauty, and slim design, delivering a modern aesthetic that traditional French doors cannot match.
Quality, Flexibility, and Innovation
Every Lanai Door system is manufactured in Southern California using premium 6063-T5 aluminum, also known as architectural alloy. This material provides:
-
Excellent corrosion resistance.
-
High strength-to-weight ratio for large panels.
-
A long-lasting, low-maintenance solution compared to wood.
Because we design and maintain our own extrusion dies, we have full control over innovation and improvements. For example, in 2007 we introduced our low-rise ADA threshold option in response to customer demand, expanding accessibility across commercial and residential projects.
Engineered for Extremely Large Openings
Lanai folding door and window systems are built to create some of the largest openings in the industry:
-
Panels up to 4’ 3” wide by 13’ 1” tall, weighing up to 350 lbs.
-

-
In a system that wide, nearly 60 feet of glass can be showcased.
