French & Double Doors

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

French and double doors bring a room to life in ways a single door never can. They widen the opening, let in Florida light, and connect indoor living space to lanais, pool decks, and garden patios. In Naples, that opening also has to stand up to hurricane season. Winslow Windows & Doors installs paired impact-rated French doors with laminated glass in every lite, engineered to meet Florida Building Code High-Velocity Hurricane Zone requirements. We carry configurations from PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass, and our installation crews work across Collier County daily. Call (239) 899-6411 to start a quote.

Product Overview - French & Double Doors

French doors are a pair of hinged doors that meet in the center of an opening and swing inward or outward. A double door works the same way, with symmetrical sightlines so both panels read as one clean architectural statement. What separates these from the decorative French doors you’ll find in a big-box store is what’s inside the glass. Every lite uses laminated impact glass with a PVB interlayer, so the glass is designed to hold in the frame if debris strikes it during a storm. That’s a non-negotiable for coastal Naples homes.

The frame carries equal weight. We offer aluminum and vinyl extrusions engineered for the wind loads common along Gulf Shore Boulevard, Park Shore, Aqualane Shores, and the newer developments moving east toward Golden Gate and Ave Maria. Hinged impact doors this wide need frames that stay square under pressure, and multi-point locking hardware at the top, bottom, and center keeps the meeting stiles tight when the wind pushes against them.

These doors fit a broad range of Naples architecture, from Mediterranean stucco homes with arched transoms to clean-lined contemporary builds in Esplanade and TwinEagles. They work well as primary living-area openings, master-suite terrace doors, and dining-room transitions to outdoor kitchens. Winslow Windows & Doors has installed French and double doors across Naples since long before the 2023 Florida code changes tightened HVHZ requirements, so we understand what these openings demand in terms of engineering and installation.

Technical Specifications

Here is what we can configure for your Naples property. These are the working numbers and options we quote from daily, not a manufacturer’s generalized brochure.

• Frame materials: Aluminum (thermally improved where needed) and vinyl.
• Maximum width: Up to 96 inches wide, depending on configuration and wind-zone calculations.
• Glass options: Laminated impact glass with PVB interlayer, Low-E insulated glass, tinted glass, clear glass.
• Finish options: White, Almond, Bronze, Black, Tan.
• Design pressure: Matched to your wind zone, up to +/-100. We never push higher than the zone requires.
• Hardware: Multi-point locking systems at the meeting stiles, flush bolts on secondary panels where specified.

Every quote includes a written line-item breakdown so you can compare configurations without guessing. Call (239) 899-6411 and we’ll walk through which combination fits your opening.

Hurricane & Compliance Performance

These six features are what make the French & Double Doors a real hurricane product, not a standard patio door with an impact sticker on it.

Laminated Impact Glass

Every lite carries a PVB (polyvinyl butyral) interlayer bonded between two panes of glass. If a storm-driven branch or tile fragment hits the surface, the glass may crack, but the interlayer holds the broken pieces in the frame. The opening stays sealed, and your home stays protected from wind-driven rain and pressure changes.

Miami-Dade NOA / FL Product Approval

Each configuration carries Miami-Dade Notice of Acceptance and Florida Product Approval numbers. These numbers are issued per configuration, not per product family, so the exact NOA or FL number depends on the size, glass, and hardware you select. We verify the correct submittal on your specific quote before permitting.

FBC / HVHZ Compliance

The door system is engineered to Florida Building Code High-Velocity Hurricane Zone requirements. HVHZ is the stricter standard that applies to Collier County and Miami-Dade. What gets installed in Naples must meet that bar, and our quotes specify it in writing.

TAS 201 / 202 / 203 Testing Context

HVHZ-rated products are tested under a protocol family that includes TAS 201 for large-missile impact, TAS 202 for cyclic wind-pressure loading, and TAS 203 for forced-entry resistance. This is the testing framework behind the NOA numbers, and it’s the reason an impact door isn’t just a thicker piece of glass.

Design Pressure for Your Wind Zone

Design pressure is a PSF rating, not a wind-speed claim. We match the design pressure to your property’s wind zone, up to +/-100, and never higher. Over-engineering sounds good in a sales pitch, but the right door is the one calculated for your lot, exposure, and opening size.

Energy Performance

Low-E insulated glass is available on this line for homeowners who want a tighter thermal envelope. In Naples, that matters in August when west-facing openings bake all afternoon. We’ll review energy glass options as part of your quote, alongside tinted and clear laminated selections.

Color & Glass Options

The five finish options we quote on this line cover most Naples exteriors. White and Almond work on the soft stucco palette common in Old Naples and Port Royal. Bronze and Black read better on modern builds with darker window packages, and Tan bridges the two, suiting the warmer neutrals found along Immokalee Road communities and in the Moorings.

Glass selection is less about look and more about what your opening does. Clear laminated impact glass gives the truest sightlines and works well for shaded lanais. Tinted laminated glass knocks down glare on south-facing exposures. Low-E insulated glass is the choice when the door faces direct afternoon sun and you want better thermal performance. Every option uses laminated construction, so choosing Low-E or tint does not mean sacrificing impact resistance.

Installation by Winslow Windows & Doors in Naples

An impact door is only as good as its installation. The NOA rating assumes the unit is set correctly: level, plumb, square, and anchored per the approved method. If the rough opening is sloppy or the perimeter seal is wrong, the system will not perform the way the test reports say it will. That’s why we install our own work and do not sub it out to third-party crews.

Our process starts with a pre-installation inspection of the rough opening. We check the header, the king studs, the subfloor, and the condition of the existing flashing. Coastal Naples buildings present specific issues: salt air corrodes fasteners, stucco hides rot behind old frames, and second-floor openings on beachfront condos need attention to anchor selection. We’d rather find those problems before the new door goes in than after.

Installation follows AAMA 2400 and 2410 standard practice. We set the frame level, plumb, and square, shim at the approved points, and anchor per the manufacturer’s NOA details. The perimeter gets an AAMA 812 low-expansion foam sealant, which allows the building and the frame to move independently without breaking the seal. After final hardware adjustment, we water-test the installation and walk the opening with you before cleanup.

Permitting in Collier County and the City of Naples requires the product NOA or Florida Product Approval documentation as part of the submittal package. We know which documents are needed and we include them with the permit set when you contract with us.
