Fold walls open with AG Millworks Bi-fold Patio Doors and change your view of the world. Narrow site lines are available for maximum light, and if you want to go super-big, we make bi-folds with individual door panels as large as 4 feet wide and 13 feet tall. Made in the USA, our doors are energy-efficient and fully customizable with flat panels, divided lites and lock rails. Exquisite wood surfaces on the interior provide warm, luxurious design details. Thick extruded aluminum exteriors with durable baked-on Kynar paint in any imaginable color completes the picture. Bi-Fold patio doors are also available with wood exteriors (limited warranty).

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.
When exposure to sun and rain is an issue, opt for Aluminum Clad/Wood Patio Doors. We combine a sleek, tough, low maintenance exterior of 1/16" thick extruded aluminum with a rich, warm, all-wood interior to give you the best of both worlds. AG offers 5 standard clad 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.
