The 30-Second Verdict
Both are Florida-made impact-window brands engineered for hurricane country. PGT is the largest and most widely available, with both vinyl (WinGuard Vinyl) and aluminum lines and strong design-pressure ratings — a default choice across the state. CGI (also Florida-based) specializes in aluminum impact windows known for high design pressures and a strong reputation in South Florida's High-Velocity Hurricane Zone (HVHZ). For HVHZ homes (Miami-Dade/Broward), both qualify; CGI is a coastal favorite, while PGT's broader lineup and dealer network give it an edge for statewide availability.

Frequently Asked Questions
Do PGT and CGI windows meet Miami-Dade HVHZ codes?
Both offer product lines approved for Florida's High-Velocity Hurricane Zone (Miami-Dade and Broward), which has the strictest impact requirements in the state. Always confirm the specific model carries a current Miami-Dade NOA (Notice of Acceptance) or Florida Product Approval for your wind zone.
Are aluminum or vinyl impact windows better for Florida?
Aluminum frames (CGI's focus, and PGT's aluminum line) are extremely strong and allow narrower frames with more glass, but conduct more heat. Vinyl frames (PGT WinGuard Vinyl) insulate better, lowering cooling bills in Florida's heat. For energy efficiency, vinyl; for maximum strength and slim sightlines, aluminum.
