French & Double Doors

French & Double Doors in Miami, FL | Winslow Windows & Doors

French doors have a way of making a room feel twice as large and three times as bright. The paired, glass-heavy profile opens a wall of light while still giving you a clean transition from living room to lanai, dining room to deck, or primary suite to morning coffee outside. But in Miami, FL, a French door has to do a lot more than look elegant. It has to stand up to hurricane season, hold its alignment in salt air, and pass a very specific set of code requirements. That’s where our impact-rated French & Double Doors come in, and why Winslow Windows & Doors installs them with the same care the engineering deserves.

Product Overview - French & Double Doors

What separates an impact-rated French door from a decorative one is what you can’t see at a glance. The laminated glass sits in every lite. The frames are aluminum or vinyl, engineered with reinforced profiles and multi-point locking hardware that holds both leaves secure. The sightlines stay symmetrical, so the door reads as a true French profile from inside and out. That matters in Miami, FL architecture, where these doors commonly open onto covered terraces, pool decks, and courtyard patios. They’re equally at home in a 1920s Coral Gables Spanish revival or a new construction spec home in Doral.

Paired impact-rated French doors with laminated glass in every lite give you a consistent barrier from jamb to jamb. There’s no weak leaf, no decorative panel that compromises the opening. When closed and locked, both doors are working members of the hurricane protection system. When open, they disappear into the wall and let the room breathe. Winslow Windows & Doors carries these through our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, and our Miami installation crews set them level, plumb, and square so the panels meet cleanly and the hardware engages like it’s supposed to.

Technical Specifications

Here’s the spec sheet in plain language. These are production options, not one-off custom builds, though lead times and exact configurations depend on what you choose.

• Frame materials: Aluminum or vinyl. Aluminum suits modern, high-CGI coastal homes and larger openings. Vinyl works well inland, where thermal performance and budget matter more.
• Maximum width: Up to 96″ wide for a paired configuration, measured across the full frame opening.
• Glass options: Laminated impact glass with a PVB interlayer, Low-E insulated glass, tinted glass, or clear glass.
• Finish options: White, almond, bronze, black, and tan.
• Hardware: Multi-point locking hardware that secures both leaves at head, sill, and meeting stile.
• Design pressure: Matched to your specific Miami, FL wind zone, up to +/-100. Never higher than the opening requires.

We keep the choices tight because in Miami-Dade County, every option has to earn its place. A finish isn’t just a color, a glass type isn’t just a preference, and a frame material isn’t just a style decision. Each combination is tested and approved as a system.

Hurricane & Compliance Performance

Every claim below ties to a code requirement or a test protocol. No marketing fluff. In Miami, FL, the building department wants proof, and so should you.

Laminated Impact Glass

Laminated impact glass has a PVB (polyvinyl butyral) interlayer bonded between two panes. Under impact, the glass may crack, but the interlayer holds the glass in the frame, keeping the building envelope sealed. This is the core of what makes a Miami-Dade rated door a Miami-Dade rated door.

Miami-Dade NOA / Florida Product Approval

Every configuration carries either a Miami-Dade NOA (Notice of Acceptance) or a Florida Product Approval number, issued per configuration. The exact number depends on the glass, frame, and size combination. We verify the approval on your specific quote before you sign anything.

FBC / HVHZ Compliance

These doors are engineered to Florida Building Code (FBC) High-Velocity Hurricane Zone (HVHZ) requirements. HVHZ is the strictest wind-load standard in the state, and Miami, FL sits fully inside it. No exceptions, no shortcuts.

TAS 201 / TAS 202 / TAS 203 Testing Context

The protocol family behind HVHZ ratings is TAS 201 (large-missile impact), TAS 202 (cyclic wind-pressure loading), and TAS 203 (forced-entry resistance). When someone says a door is impact-rated in Florida, these are the tests that prove it.

Design Pressure for Your Wind Zone

Design pressures are matched to your wind zone, up to +/-100, and never higher. Higher-rated product costs more and buys you nothing if your opening doesn’t require it. We size the rating to the location in Miami, FL where the door is going.

Energy Performance

Low-E and insulated glass options are available for homes where the door faces afternoon sun or where the air conditioner runs most of the year. In Miami’s climate, energy-smart glass is a real consideration, not an upsell.

Color & Glass Options

Five finishes and four glass types cover almost every home style you’ll find between Coconut Grove and Kendall. White frames disappear into light walls and bright rooms, a classic choice for coastal interiors. Almond and tan work beautifully on Mediterranean homes with stucco exteriors and warm terrazzo floors. Bronze and black frames read more contemporary, especially on white or gray exteriors, and they hold up visually against the heavy sun exposure Miami, FL gets year-round.

On the glass side, clear laminated impact glass is the honest default, clean and bright, with the protection built in. Tinted glass cuts glare on west-facing patios where the evening sun comes in low. Low-E insulated glass is the workhorse for energy, reflecting heat while keeping the room brighter than a heavy tint. And yes, you can combine Low-E with the impact interlayer in most configurations. The glass is laminated for impact first, and the Low-E coating or tint becomes a performance layer on top of that.

Installation by Winslow Windows & Doors in Miami

A door that tested perfectly at the lab can fail in the field if it’s installed poorly. That’s the uncomfortable truth in Miami, FL, where a French door opening sees rain, wind, salt, and humidity all in the same week. Our installation crews work to AAMA 2400/2410 practice and seal the perimeter with AAMA 812 low-expansion foam. That’s not product marketing. That’s how the opening stays watertight for the life of the door.

The process starts with a pre-install inspection of the rough opening, because no amount of shimming fixes an opening that’s out of plane by an inch. We check the floor, the header, and the sides. Then we set the frame level, plumb, and square, which is what lets the multi-point hardware line up and the French doors meet cleanly at the center. The perimeter gets a full AAMA 812 foam seal, flashings are installed correctly for your cladding type, and we finish with a water test before cleanup.

Permitting matters here. Many Miami-Dade and Broward municipalities want the NOA or FL Product Approval number on the permit submittal, and the person installing the door needs to know how to reference it correctly. Improper installation compromises the NOA-rated system, plain and simple. That’s why we handle the installation ourselves and why the door is only as good as the crew setting it.
