Impact protection, built for South Florida

The BF1199A is WinDoor's bi-fold door, accordion-style panels that fold and stack to one side to open a wall completely rather than leaving half of it as fixed glass. It is aluminum, LMI impact-rated for the HVHZ, and built to the same luxury standard as the rest of the WinDoor catalog. Where the flagship 8100 slider gives the largest single panels, the bi-fold gives the widest clear opening, since nothing stays in the frame when it is open.

Armor Pro specs the BF1199A on entertaining and indoor-outdoor openings where the goal is to make the wall disappear, a pool deck, a great room, a summer kitchen. The choice between the bi-fold and the 8100 slider comes down to whether the opening should stack to the side or slide and pocket; both are luxury-tier WinDoor doors. The BF1199A is the full-wall folding option in the line.

Frequently Asked Questions

The BF1199A opens through accordion-style panels that fold and stack to one side, so the whole wall opens up instead of leaving half of it as fixed glass. Where the 8100 slider gives the largest single panels, the bi-fold gives the widest clear opening because nothing stays in the frame when it's open. We install it on indoor-outdoor openings like pool decks, great rooms, and summer kitchens.

Yes. The BF1199A carries an LMI (Large Missile Impact) rating and is approved for High-Velocity Hurricane Zone installations across South Florida. It's built with laminated impact glass and laminated insulating impact glass, and is rated to 65 psf positive and -70 psf design pressure. We'll confirm the certified rating for your opening at the quote.

Each bi-fold panel runs up to 48 inches wide and 105 inches tall, and panels link together so the total opening width is built from multiple folding panels. The frame is 5 inches deep to carry the folding hardware. We'll lay out the panel count to span your opening and stack neatly to the side.

The BF1199A uses insulating laminated impact glass with a U-factor of 0.77 and a condensation resistance of 37. SHGC ranges from about 0.16 with Solargray up to 0.50 with Clear, so you can control solar heat gain while keeping the view. We'll recommend a tint that fits your sun exposure and energy goals.

Standard finishes include Bone White, Bermuda Bronze, Clear Anodize, Black, Southbeach Silver, Velvet Gray, Patio White, and Southern Bronze, with woodgrain options like Hazelnut Brown, Mahogany Red, and Walnut Brown. Two-tone combinations and custom colors are available, and hardware comes in Satin Nickel, White, Bronze, or Black. We'll match the finish to your home inside and out.

The choice comes down to whether the opening should stack to the side (bi-fold) or slide and pocket (the 8100); both are luxury-tier WinDoor doors that make the wall disappear. Installed price depends on the opening width, panel count, glass package, and finish, so a wide full-wall bi-fold sits at the premium end. Armor Pro gives a free 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 folding door is made of multiple panels hinged together that fold and stack to the side, opening a wall almost completely to a patio or lanai. It creates a seamless indoor-outdoor connection that a standard slider cannot, and the impact version is laminated and HVHZ-tested for hurricane protection.
