The complex frame components required for patio French doors were once impossible to attain with fiberglass. Milgard's research and development team changed all that. We engineer fiberglass French doors (in-swing and out-swing) and French-style sliding patio door systems that are as attractive as they are weatherproof and durable. It's a difference you'll appreciate for a lifetime.
