Unfolding New Possibilities Inside and Out

The Best-Performing System Ever

We’ve tested our panels over 20,000 operational cycles for decades of performance and built in innovations designed to handle wind, water, extreme temperatures, forced entry, and structural load.

Our Most Streamlined Designs

Besides offering the slimmest frames in the industry, Generation 4 also minimizes exposed hardware by concealing all visible frames to structure attachment points for a more streamlined appearance.

Even More Configuration Flexibility

The panels of our Generation 4 product have the option of moving in stacks of four or six—unattached to the side jamb, and possessing the ability to stack to the left, right or center of the opening.

Explore Unique Generation 4 Features

Our new Generation 4 Folding Glass Walls offer features that other products can’t.

1
Greater Flexibility and Unlimited Widths

FourFold and SixFold Panel Sets move and stack to an opening’s left, right, or center—adding more convenience for operators, and enabling widths beyond those of other bi-fold doors. Simultaneously, Floor Supported Technology reduces the need to modify headers on top.

2
Streamlined Surfaces

A special multipurpose frame insert enhances aesthetics, by enabling all frame attachment points to be hidden—and provides a space where businesses and residences can conceal cable routing for security and lighting.

3
Easier Opening and Closing

By reducing friction, our highly-advanced Gothic Arch Roller System enables panels to be slid open and closed by anyone—smoothly, quickly, and effortlessly.

4
Enhanced Safety

Four sill options with removable inserts eliminate the concern of high-heeled shoes getting caught in tracks. In addition, our Flush and Low Profile Saddle sills are ADA-compliant (and easier on bare feet).

5
Smoother Operation Over Time

Our unique width adjustment feature maintains consistent seal compression, while guarding against alignment problems caused by settling.

6
Sleek, Ultra-Contemporary Look

Generation 4 walls feature the slimmest panels in the industry, with smoother, more streamlined surfaces (enhanced by our patented TwinX structural reinforcement, which helps to eliminate mid-level hinges).

7
Unequaled Comfort and Security

Our exclusive Bionic Turtle® technology provides an insulating thermal break within the frame, adding extra comfort and energy efficiency. It also furnishes a concealed channel that houses locking rods—adding security and enabling slimmer profiles.
