PGT WinGuard Aluminum French Door FD450

Yes. The FD450 is large-missile impact-rated and is tested to the Florida hurricane standard, approved for the High-Velocity Hurricane Zone that covers Miami-Dade and Broward. Its laminated impact glass resists wind-borne debris, so it protects the opening without separate hurricane shutters.

The FD450 is engineered up to 44.563 x 120.75 in. Larger sizes carry a lower pressure rating, so the exact maximum for your opening depends on the configuration and glass package — we confirm the rating at measurement.

Armor Pro installs the PGT WinGuard Aluminum French Door FD450 throughout South Florida as a licensed, insured contractor. We measure each opening, handle the product-approval paperwork and permitting, install it to spec, and stand behind the workmanship — and the FD450 is HVHZ code-compliant when installed to its approval.

WinGuard Aluminum is PGT's flagship aluminum impact line and runs the full operation range on one extrusion platform: single hung, horizontal roller, casement, awning, fixed picture, architectural shapes, plus sliding glass doors and French doors. Because every style shares the same frame family, a whole house can be specified consistently instead of mixing systems opening by opening. It's been PGT's reference impact-window platform in Florida since 1998.

Yes. Every WinGuard Aluminum product is large-missile impact-rated and eligible for the High-Velocity Hurricane Zone, which covers Miami-Dade and Broward counties. The line carries one of the deepest Miami-Dade NOA libraries in the industry, glazed with PGT's Diamond Glass laminated impact glass. The exact design pressure depends on the size and configuration of each opening, which we confirm against the Florida Building Code on your quote.

PGT has built impact windows and doors in Venice, Florida since 1980 and is the largest impact-window and -door manufacturer in the country. It was the first company to develop impact-resistant products that met Miami-Dade County's hurricane code after Hurricane Andrew, and the line is engineered specifically for Florida conditions. PGT is now part of the MITER Brands family, alongside WinDoor, ECO, and NewSouth, but the products are still made in Florida under the PGT name.

PGT's impact lines are — but not every PGT line is impact-rated, so this is the first thing to get straight. The WinGuard Aluminum, WinGuard Vinyl, and Sparta lines carry Miami-Dade Notices of Acceptance and Florida Product Approvals that make them eligible for the High-Velocity Hurricane Zone (Miami-Dade and Broward counties). EnergyVue, ClassicVue Max, and Scout are non-impact lines and cannot be installed in the HVHZ. We confirm the right line and approval for your address and openings on the quote, and we pull the permit with the approval documents on every job.

A swing door is hinged and opens in or out — a French door is a glazed door (often in pairs), while an entry door is the main door to the home. The impact versions use laminated glass and reinforced frames and hardware tested to the HVHZ standard, protecting the opening against debris and forced entry.
