The innovative NW Aluminum 840 provides the slimmest and most thermally efficient aluminum frame Generation 4 Folding Glass Walls. With a frame profile styled in a crisp, angular design, the intersection of two folding panels is a mere 3 7/8" (99 mm). NW Aluminum 840 offers the largest panel sizes available with floor supported panels capable of reaching system heights up to 11' 6" (3500 mm) and panel widths up to 3' 7" (1100 mm). The larger panel sizes allow for the integration of FourFold and SixFold Panel Sets. The panels are able to move and stack either to the right, left, or center within the same track allowing the panels to be stacked in the most convenient location as needed.
