Fold walls open with AG Millworks Bi-fold 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 Doors are also available with wood exteriors (limited warranty).
