Frequently Asked Questions
The CA740A is PGT's WinGuard Aluminum casement window, side-hinged with a crank-out sash that swings open like a door and pulls in a tight weather seal when closed. Because it cranks fully open, it's a great choice for catching breezes and for hard-to-reach spots like over a counter. It's built on the WinGuard 740-series frame, so it mulls cleanly alongside the AW740A awning and PW740A picture units.
Yes. The CA740A is LMI (Large Missile Impact) rated and holds Miami-Dade Notice of Acceptance (NOA) 23-0816.12, valid through April 11, 2028, which clears it for the High-Velocity Hurricane Zone in Miami-Dade and Broward. It uses PGT's Diamond Glass laminated impact glazing. We confirm the current approval and design pressure for your specific opening at the time of quote.
The CA740A is available as a single casement (up to 37 by 63 inches at +90/-130 psf), a twin casement (up to 74 by 63 inches), and triple configurations up to 134 inches wide, all at up to 63 inches tall. Multi-unit configurations carry a +70/-90 psf design pressure. We size and combine units to fit your opening and verify the rating before ordering.
The CA740A uses a 7/8-inch laminated insulating glass unit with packages including Energy Shield, Energy Shield Max, and SolarControl LowE2, with optional argon fill. U-factors run from about 0.62 to 0.67 and SHGC from 0.18 to 0.29 depending on the package and grids. For South Florida sun, the Energy Shield Max and SolarControl LowE2 options give the lowest solar heat gain, and we'll help you choose.
The CA740A offers an egress hinge as a hardware option, which lets the sash open wide enough to serve as a code-required emergency exit in bedrooms. It also comes standard with a multi-point locking system, a nesting handle, a washable hinge, and a vent limiter device. We'll confirm whether your specific opening size and the egress hinge meet your local egress requirements during the estimate.
Installed pricing for the CA740A depends on the configuration you choose (single, twin, or triple), the glass package, and the condition of your opening. The window is approved for block, masonry, concrete, and metal substrates across 25 tested anchor conditions, so the install is matched to your wall type. Armor Pro provides a free in-home estimate so you get an accurate number for your project rather than a generic per-window price.
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.
