Frequently Asked Questions
The 9050 is WinDoor's thermally broken aluminum terrace door, a hinged (swinging) patio door available in single and double configurations up to 84.5 by 128 inches. Unlike a slider, it swings open like a French-style door, which suits openings where you want a wider clear walk-through. We install it where a swing door fits the floor plan better than a track-mounted slider.
Yes. The 9050 carries Florida Product Approval FL29783.R19 and an LMI (Large Missile Impact) rating, certifying it for High-Velocity Hurricane Zone installations. It's rated up to 100 psf positive and -120 psf negative design pressure with a 15 psf water rating. We'll confirm the approval and design pressure for your specific opening at the quote.
The 9050 is thermally broken on a 4-9/16 inch frame depth, and with its insulating glass packages it reaches a U-factor of 0.56 and a condensation resistance of 44, which is notably better than non-thermal aluminum doors. SHGC ranges from about 0.14 (Solargray) to 0.39 (Clear), so you can dial in solar control. We'll recommend the glass that balances energy savings and your view.
Yes. The 9050's sightlines are designed to match the 8100 sliding glass door and the 9020 picture window, so a project that mixes those products keeps clean elevation continuity. We spec the matching units together so the frames and rails line up across the whole elevation. Finishes and grids can be coordinated to read as one system.
A single 9050 ranges from 28 by 72 inches up to 46 by 128 inches, and a double ranges from 48 by 72 inches up to 76.5 by 120 inches. That gives flexibility for both standard patio openings and tall, dramatic terrace entries. We'll measure your opening and confirm which configuration and size works within the certified range.
Installed price depends on whether it's a single or double door, the overall size, the glass package, and the finish and hardware you choose. Because the 9050 is a thermally broken impact door built up to 84.5 by 128 inches, pricing scales with the opening. Armor Pro provides a free, no-obligation estimate matched to your exact door.
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 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.
