AG Millworks folding window systems are handcrafted and made to order. They offer the ability to fold away, creating a wide, unobstructed opening and expanding the usable area of a home. These windows are particularly effective as pass-through windows, connecting kitchens to patios or decks for entertaining. With options to match any of our bifold, sliding or swing door systems, from ultra modern to classic, our design options allow you to create custom bifold window systems that will transform your space into an indoor/outdoor paradise.
