Our horizontal folding walls, windows, and doors (also called Bi-Fold) fold to either one side of the opening or both sides, creating a flexible space. They can be utilized in both commercial and residential settings as well as either exterior or interior. Our superior American engineered hinges and motion hardware allow for smooth operation of units up to 40′ wide and 18′ tall. Thermally broken aluminum and dual paned low-E glass make the AL62-HF extremely energy efficient.

Custom sizes, configurations, glass, and multiple sill options are available along with SDL (simulated divided lites or grilles) and integrated panic hardware (for commercial applications). There is also a floor-mounted system for applications where header weight support is problematic.
