Frequently Asked Questions
The PW740A is PGT's WinGuard Aluminum casement-companion picture window, a fixed (non-operating) unit designed to mull seamlessly with the CA740A casement and AW740A awning in the 740-series frame family. We use it to build clean multi-window assemblies, pairing a large fixed lite for the view with operable units alongside it for ventilation. It uses PGT's Diamond Glass laminated impact glazing on a 2.75-inch aluminum frame.
Yes. The PW740A is LMI (Large Missile Impact) rated and carries Miami-Dade Notice of Acceptance (NOA) 23-0816.08, valid through April 11, 2028. That approval clears it for installation throughout the High-Velocity Hurricane Zone in Miami-Dade and Broward counties. We confirm the current NOA and the design pressure for your specific opening at the time of quote.
The PW740A picture window runs from a minimum of 18 by 18 inches up to a maximum of 32 square feet of glass area. At those sizes it carries a design pressure of up to +90/-130 psf, which suits high-wind coastal South Florida exposures. We size each unit to your opening and verify the rating before ordering.
The PW740A uses a 7/8-inch laminated insulating glass unit and offers several packages, including Energy Shield, Energy Shield Max, and SolarControl LowE2, with optional argon fill. U-factors range from about 0.49 to 0.56 and SHGC from 0.19 to 0.33 depending on the package and grids. For South Florida heat, we usually steer homeowners toward the Energy Shield Max or argon SolarControl LowE2 options for the lowest solar heat gain.
The PW740A comes in White as standard, plus Bronze, Black, and Clear Anodized aluminum frame finishes, so the picture window can match the casements and awnings it mulls with in the 740 family. Grid options include a 1-inch raised/flat profile or a 9/16-inch flat grid-between-the-glass style. We'll match the finish and grid across the whole assembly so a multi-window wall reads as one unit.
Installed cost depends on the window size, the glass package you choose, and the condition of the opening, so Armor Pro provides a free estimate rather than a flat per-window price. Because the PW740A is so often mulled with CA740A casements and AW740A awnings, the price for a combined assembly will also reflect how many units share the opening. We'll measure, recommend a glass package for your exposure, and give you a written quote.
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.
