About the Manufacturer

About WinDoor

WinDoor designs and manufactures premium aluminum impact windows and doors for luxury residential and high-end light commercial projects, operating from a 320,000 square-foot facility in Orlando, Florida. WinDoor's products are specified for five-star resorts, luxury high-rise condominiums, and custom estates across Florida and the Caribbean, where the largest certified panel sizes and most architecturally distinctive configurations are the deciding factors.

WinDoor's flagship 8100 Series sliding glass door carries one of the industry's largest certified panel sizes (up to 60 by 144 inches) and supports 2 through 5 tracks, pocketing or non-pocketing configurations, and 90 or 135 degree corner geometries. The Estate Series adds bifold, pivot, and pocketing doors plus the Envista seamless-glaze window system. Thermally broken aluminum frame options across the catalog deliver superior energy performance while preserving the clean sightlines high-end architecture requires.

Now part of the MITER Brands family (alongside PGT and ECO Window Systems), WinDoor remains the luxury tier where panel size, custom configurations, and engineering customization are non-negotiable. Armor Pro installs WinDoor products across South Florida for waterfront, estate, and high-rise residential projects.

At WinDoor, we do more than just create exceptional luxury doors and windows — we open possibilities. … Our craftsmanship, attention to detail, and high performance ratings have made WinDoor the product of choice for homeowners, architects, and builders since 2001.

Frequently Asked Questions

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.

WinDoor is engineered around scale: the flagship 8100 sliding glass door certifies some of the largest impact-rated panels in the business for the HVHZ, and the 9020 picture window reaches well past what most impact windows can certify. The doors also support pocketing layouts and 90- or 135-degree corners that take the post out of a corner-of-room view. That makes WinDoor the line architects spec when the opening itself is the architecture, which is why we install it on waterfront and view-driven custom homes.

Every WinDoor product is extruded aluminum, often thermally broken, with no vinyl or composite option. Aluminum is what lets the line carry the slim sightlines and the very large certified panels it is known for, since the frame can stay narrow while spanning a big opening. Where an aluminum sightline isn't the priority, a vinyl impact line may give better thermal performance for less money, and we'll lay out that trade-off honestly before you commit.

WinDoor has built its products in the Orlando, Florida area since 2001 and is now part of MITER Brands, the same family that owns PGT. It remains MITER's luxury, architect-spec aluminum tier rather than a value line, with each product custom-manufactured to the opening. Being a Florida-built brand under a large parent means the compliance, engineering, and parts support behind the product are well established, which matters on a high-end install.

WinDoor is the right fit when the design calls for very large impact-rated glass, clean architectural sightlines, and custom configurations, with deep glass, color, and hardware options and sightline matching across the doors and windows. It is genuinely premium, so it is usually specified where the budget supports the best aluminum slider, pivot, or bi-fold made rather than as a value choice. We'll tell you where WinDoor is the clear call versus another line we carry, based on your openings, design pressures, and budget.

WinDoor provides a manufacturer warranty on its products; we review the current terms and exclusions with you before you sign, since coverage varies by product and configuration. Separately, Armor Pro warranties our own installation labor, the anchoring, watertight seal, and finish work that keep an impact product performing in a storm. We keep the two clearly separated so you know exactly who stands behind what.
