Built for Strength and Performance
Traditional French doors may offer elegance, but they fall short when it comes to durability, energy performance, and space efficiency. Lanai Doors® are engineered to outperform French and sliding glass doors with bi-folding door systems that maximize light, optimize openings, and deliver industry-leading exterior performance ratings.
Our exterior folding door systems are:
-
Title 24 compliant for energy efficiency.
-
Hurricane-rated to withstand extreme wind and impact conditions.
-
Water-tight and weather-tight, ensuring performance in heavy rain, humidity, and storm conditions.
-
Available with forced entry ratings, providing added security for peace of mind.
When you choose Lanai, you’re choosing a system that’s as tough as it is beautiful.
Optimize Space and Light
Unlike traditional French doors that swing inward or outward and take up valuable space, Lanai bi-folding exterior doors fold neatly to the side, allowing you to use the entire opening. That means:
-
More usable square footage indoors.
-
Maximum natural light pouring into your space.
-
A seamless connection between indoors and outdoors.
Our doors don’t just open—they transform your living space by creating an expansive “wall of glass” that blends beauty with durability.
Custom Bi-Folding Door Solutions
Every project is unique, which is why Lanai offers flexible configurations to suit residential and commercial needs. Popular designs include:
-
Everyday access panels for convenience.
-
Configurations where two panels act as French doors for day-to-day use.
-
Multi-panel systems that fold away completely for large openings.
Whichever configuration you choose, all Lanai systems are backed by engineered strength and tested performance ratings, ensuring your door system is ready for both everyday living and extreme conditions.
Beauty and Durability in One System
With Lanai Doors, you never have to choose between style and strength. Our exterior folding systems offer:
-
Slim 3-inch stiles and rails for less obstruction and more light.
-
Multiple materials including aluminum, natural wood, and aluminum-clad wood.
-
Single or dual glazing systems for enhanced thermal performance.
-
A wide range of finishes, colors, and divided lite options for a French-door look with modern durability.
