Bi-Fold Doors

Bifold doors are excellent in areas where unobstructed views are required. Utilizing our OS2 system you get the energy performance benefits of a Thermally Broken system, narrow sightlines, which are much smaller than aluminum, and you can span wider and taller openings due to the structural stability of the steel sections. Units can hinge from the inside, outside, or in the center to take maximum advantage of the available space. Each unit is designed specifically for the opening. Custom hardware is utilized to create either a flush sill or step as required. The first leaf can operate independently with a multi point lock to serve as the primary door. The adjacent leaf can offer a French door application. Units can slide in one direction or can part in the middle. Talk to us about your design and we will work with you to accomplish you goals.
