Impact protection, built for South Florida

The 8100 is WinDoor's flagship and the door the brand is known for: a sliding glass door with one of the largest certified panel sizes in the industry, up to 60 by 144 inches. That size is the whole point. It lets a wall of glass run with fewer interruptions, and the configuration range backs it up, two through five tracks, pocketing and non-pocketing layouts, and 90- or 135-degree corner geometries that take the post out of a corner-of-room view. It is rated to 100 psf in both directions with LMI impact certification for the HVHZ.

Armor Pro specs the 8100 on the luxury waterfront and view-driven projects where the opening is the architecture and the budget supports the best slider made. The corner configurations in particular are the kind of detail a custom home is designed around. For an opening that should fold the wall away entirely, the BF1199A bi-fold is the companion; for a statement entrance, the PV9998A pivot. The 8100 is the marquee sliding door in WinDoor's luxury catalog.

Frequently Asked Questions

The 8100 carries one of the industry's largest certified panel sizes, with sliding panels up to 60 by 144 inches and a per-panel maximum of 84 by 144 inches. That large size is the whole point of this door, letting a wall of glass run with fewer post interruptions. We'll confirm the exact certified size for your opening at the quote.

Yes. The 8100 carries LMI (Large Missile Impact) certification and is approved for South Florida's High-Velocity Hurricane Zone. It is rated to 100 psf positive and negative design pressure, with configurations available up to 125 psf positive and -150 psf, and we install it as a code-compliant impact slider throughout the HVHZ.

The 8100 is available in 2 through 5 track configurations, in both pocketing and non-pocketing layouts. It also supports 90- or 135-degree corner geometries that remove the post from a corner-of-room view. We'll lay out the track count and pocketing option around your opening so the glass runs the way the architecture intends.

The 8100 has a U-factor of 1.09 across its glass packages, with SHGC ranging from about 0.22 to 0.65 depending on the tint you choose. Options run from 6 mm Clear (SHGC 0.59) to lower-gain tints like Graylite II (SHGC 0.27) and SC Gray (SHGC 0.28), plus laminated, laminated insulating, and high-performance Low-E builds. We'll help you pick the glass that fits your sun exposure and view.

Standard finishes include Bone White, Bermuda Bronze, Clear Anodize, Black, Southbeach Silver, Velvet Gray, Patio White, and Southern Bronze, plus woodgrain looks like Hazelnut Brown, Mahogany Red, and Walnut Brown. Two-tone combinations such as Bermuda Bronze exterior with Bone White interior are offered, and custom colors are available. We'll match the finish to your home's exterior and interior.

Installed price depends on the size of the opening, the number of tracks and whether it pockets, the glass package, and the corner geometry, since the 8100 is a flagship door built for very large openings. As a specialty slider for view-driven and waterfront projects, it sits at the higher end of the slider range. Armor Pro provides a free, no-obligation estimate sized to your exact opening.

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 sliding glass door (SGD) glides on a bottom track and stacks panels to one side, giving a wide glass opening to a patio or lanai. The impact version uses laminated glass and a heavy reinforced frame tested to the HVHZ standard, so it protects the largest opening in most homes without needing shutters.
