Generation 4 Folding Glass Walls
A Transformational Product Family Made by Originals, for Originals
Generation 4 walls are engineered with a host of features and benefits never before seen in our industry. Their next-level performance features effortless operation, and field-tested security that stands up to the harshest weather and use. Meanwhile, the industry’s sleekest aesthetics inspire transformative design, featuring striking panels in solid wood, aluminum, or clad.
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.
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.
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.
By reducing friction, our highly-advanced Gothic Arch Roller System enables panels to be slid open and closed by anyone—smoothly, quickly, and effortlessly.
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).
Our unique width adjustment feature maintains consistent seal compression, while guarding against alignment problems caused by settling.
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).
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.
Any glass wall can show you a horizon. But only Generation 4 lets you explore new ones. Our reinvented systems are filled with features to create new possibilities.
