Vinyl Windows

PGT WinGuard Vinyl



Founded in 1980, PGT pioneered the U.S. impact-resistant window and door segment, growing from just four employees to approximately 1,700 at the manufacturing facility in Venice, Florida. After the destruction from Hurricane Andrew in 1992, PGT established itself as a leader in impact-resistant windows and doors. The WinGuard® line, with over three million units installed and no reported impact failures, continues to provide consumers with safety and security.
