AG’s Zero-Corner Bi-fold Units can turn any dark corner into a light-filled entertainment space and provide a wide open, panoramic view with no supporting post at the corner.

AG’s Window-Door Combinations consist of bi-fold doors and bi-fold windows which connect at the center, and transform an ordinary space into an indoor-outdoor paradise.

AG’s Bi-Fold Windows create a foldaway “passthrough” window which connects kitchen to patio, creating an additional dining area and enhancing your entertainment space.

The Energy Solutions Bi-Fold Door has an aluminum clad exterior with five standard color options. Clad exteriors are painted with 70% kynar 500 and meets a 2605.

We’ll match any manufacturer’s exterior clad color to ensure a consistent look between our products and theirs.
