Folding glass walls come in many different names: bi-fold doors, glass according doors, folding glass doors and more. We named our systems folding glass walls to accurately describe the performance and function of our product line. Each panel of the glass folding doors connects to the others and folds as they open—all within a single track. Folding glass walls are energy-efficient and offer wide, unobstructed openings that are not constrained by the fixed glass panels of a traditional slider.
