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.
Milgard® fiberglass patio French doors are designed to match the beauty and profile of wood patio doors, but with none of their maintenance headaches. Milgard® fiberglass patio doors ward off wind, snow and rain, year after year, without peeling, swelling, expanding, contracting, cracking or warping. They’re impervious to cold, heat, insects, salt air and corrosion. Available in custom sizes and multiple panel configurations, Milgard® fiberglass patio doors include our industry-leading industry-leading Warranty with Glass Breakage.
