WinDoor

WinDoor is a Florida-based manufacturer of high-performance aluminum impact windows and doors, founded in 1999 and headquartered in St. Augustine, Florida. The company specializes in large-format, design-forward aluminum products including sliding glass doors, casement windows, folding door systems, and pivot doors engineered to meet Florida Building Code and Miami-Dade Notice of Acceptance (NOA) requirements.

WinDoor products are positioned at the upper end of the impact-rated aluminum market, emphasizing slim sightlines, large glass areas, and architectural aesthetics alongside certified performance. The company is a brand within MITER Brands, which also owns PGT Innovations, MI Windows and Doors, Milgard, and NewSouth Window Solutions.

WinDoor distributes through a select network of window and door dealers and glazing contractors, primarily serving Florida, the Gulf Coast, and other hurricane-zone markets.
