Frequently Asked Questions
The GW9994G is WinDoor's modular, pre-glazed aluminum bay window designed for jamb-and-anchor channel coupling between adjacent panels. It works best where you want a projecting bay that brings in light and view while staying part of a coordinated assembly, since it's marketed under the Envista System for clean continuity across sightline-matched units. We install it on South Florida homes that need a true bay opening rather than a flat run of windows.
Yes. The GW9994G carries LMI (Large Missile Impact) certification and is HVHZ-approved, so it's suitable for High-Velocity Hurricane Zone projects in Miami-Dade and Broward. It uses laminated impact glass rather than separate shutters. We'll confirm the exact product approval and the configuration that applies to your specific opening at the time we quote.
Each Envista modular unit on the GW9994G runs up to 48 inches wide by 120 inches tall and is rated to +90/-90 psf design pressure. That 90 psf rating is strong for a coastal opening, and the 120-inch height supports tall bay panels. Because the design pressure required depends on your wind zone and opening, we verify the rating for your home before ordering.
The GW9994G uses laminated impact glass, either 5/8 inch for units 24 square feet and under or 7/8 inch for larger units, and is available in Clear, Tinted, LoE (Low-E), and Privacy glass options. For our hot, sunny climate we typically recommend a LoE coating to cut solar heat gain through the large bay glass area. We'll match the glass package to the room's exposure when we quote.
The GW9994G aluminum frame is available in standard finishes including Bone White, Bermuda Bronze, Clear Anodized, Black, Southbeach Silver, Velvet Gray, Patio White, and Southern Bronze, plus Woodgrains and Custom Colors. For grids you can choose Flat Bar Muntins or silicone grids between the lites in black, white, or clear. We help you coordinate the finish and grid so the bay matches the rest of your windows and doors.
There's no flat price for a bay window because the installed cost depends on the overall size, how many panels are coupled, the glass package you choose, the frame finish, and the condition of the existing opening. A projecting bay also involves more structural and flashing work than a flat window, which factors into the quote. Armor Pro provides a free, no-obligation estimate and will measure the opening to price the GW9994G for your project.
Yes. WinDoor's active aluminum impact line carries Florida Product Approval and is rated for the High-Velocity Hurricane Zone (Miami-Dade and Broward counties), with large-missile impact glass throughout. The exact design pressures depend on the specific product, panel size, and configuration, so we confirm the right rating for each opening on the quote. We pull the permit and submit the approval documents as part of every installation.
We install WinDoor's full luxury aluminum range: the 8100 sliding glass door, BF1199A bi-fold and PV9998A pivot doors, the 9050 thermally broken terrace door, FD9950A French doors, and the GD9995A impact garage door, plus the 9020 picture window, the GW9994G Envista bay window, and the Pass-Through Awning. We also service older WinDoor product still in Florida estates built since 2001, even on series the brand no longer sells. If you're comparing door and window types, our Window and Door Designer and Visualizer lets you see how each looks on your home.
A fixed (picture) window does not open — it is a sealed pane that maximizes the view and daylight. With no moving parts it is the most weather-tight and energy-efficient style, and it carries the highest design pressures, which is why it is often used for large feature openings and architectural shapes.
