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.

Smoother Operation Over Time

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

X

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.

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).

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.

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).

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.

Easier To Open, Year After Year

Relying on the same principle used by high-speed rail, the two-point contact of our Gothic Arch Roller Systems pairs with advanced sills (many of them ADA-compliant) to create panels that slide effortlessly. We’ve also tested those panels over 20,000 operational cycles—making it possible for Generation 4 walls to be opened and shut twice a day for 27 years, with no loss in performance. All of which makes the system ideal for restaurants, retail stores, office settings, and homes.

Our Sleekest, Most Contemporary Look Yet

Besides offering the slimmest frames in the industry, Generation 4 also minimizes exposed hardware. By concealing all visible frame to structure attachment points, our multipurpose frame insert creates a cleaner, more streamlined appearance.

Greater Security With Enhanced Energy Efficiency

Inside Generation 4 walls are innovations designed to meet the challenges of wind, water, extreme temperatures, forced entry, and structural load. Besides housing the system’s locking rods, our Bionic Turtle®—a patented, single-piece insulbar design—provides an exceptional insulating thermal break between the frame profiles: adding energy efficiency and year-round comfort.

Maximized Convenience, With the Most Flexible Configuration Options

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. Maximizing flexibility, these FourFold and SixFold Panel Sets enable unlimited system widths, and help to eliminate the chore of moving furniture when opening and closing walls.
