About CGI Windows & Doors
CGI Windows & Doors is a Miami, Florida-based manufacturer of impact-resistant windows and doors for the hurricane-exposed coastal markets of Florida and the broader Atlantic and Gulf Coast regions. Founded in 1992, CGI built its product line around the strict Miami-Dade County wind and impact standards that have become the benchmark for hurricane-zone fenestration performance, and the company holds extensive Florida Product Approval numbers across its aluminum impact window and door systems.
CGI's product range covers aluminum single-hung, double-hung, casement, awning, and fixed impact windows; impact sliding glass doors; impact entry doors; and specialty impact configurations for high-velocity hurricane zone (HVHZ) applications. The company's aluminum frame construction, laminated impact glass packages, and Miami-Dade Notice of Acceptance (NOA) credentials make it a specification-ready source for Florida coastal builders and architects. CGI is now part of the PGT Innovations / MITER Brands corporate family.
For specifiers working in Florida's coastal and inland HVHZ markets, CGI products provide established impact credentials and Miami-Dade approval coverage in aluminum framing. The brand is most relevant where aluminum construction and impact rating are both required — premium coastal homes, condominiums, and commercial-adjacent projects where non-PVC framing is preferred over vinyl impact alternatives.
