Double Hung Windows

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

Double hung windows are one of the most requested profiles for Naples homes, and for good reason. They offer that classic vertical-glide look with both sashes moving, plus tilt-in convenience for easy cleaning. But in Southwest Florida, the real question is whether the window can take a storm. Ours can. Winslow Windows & Doors supplies and installs impact-rated double hung windows across PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, engineered to Florida Building Code High-Velocity Hurricane Zone requirements. We serve homeowners from Old Naples to Pelican Bay, Vanderbilt Beach, and Lely Resort. Call (239) 899-6411 to talk through your options.

Product Overview - Double Hung Windows

A double hung window has two operable sashes that slide vertically, one up from the bottom and one down from the top. That top sash mobility is what separates it from a single hung, and it’s the reason many Naples homeowners choose this profile for bedrooms, living rooms, and any space where airflow matters. On a breezy afternoon near the coast, you can drop the top sash and let warm air escape while cooler air pulls in from below. It’s a small detail that makes a big difference in a climate like ours.

What makes this version different from a builder-grade double hung is the glass. These are impact windows, built around laminated impact glass with a PVB interlayer. When a storm throws debris against the glass, the glass may crack but it stays in the frame, held by that interlayer. That is the core of the impact-rated system, and it is what a standard window simply cannot do. The frame is available in aluminum or vinyl, both with reinforced profiles designed to carry the weight and stress of laminated glass in a coastal wind zone.

Architecturally, the double hung profile suits a wide range of homes across Naples. You’ll see it on ranch-style homes in Naples Park, low-rise condominium buildings near the beach, Mediterranean revivals in Pelican Marsh, and newer construction in Ave Maria. It carries a traditional proportion that fits Florida’s older architectural vocabulary without looking dated on a new build.

Technical Specifications

Every double hung window we quote is configured to order. Here is what you can specify:

• Frame materials: Aluminum or vinyl, selected based on design pressure requirements, budget, and architectural style.
• Glass options: Laminated impact glass with PVB interlayer as standard for impact protection, with Low-E insulated glass, tinted glass, and clear glass available depending on your energy and privacy goals.
• Finish options: White, almond, bronze, black, and tan.
• Screen options: Half screen for partial opening coverage, or full screen for full-height insect protection.
• Design pressure: Matched to your wind zone, up to +/-100. We never over-spec or under-spec.
• Compliance documentation: Miami-Dade NOA and Florida Product Approval numbers available per configuration, verifiable on your specific quote.

The spec sheet is only half the story. The way the window is sized, anchored, and sealed determines whether it performs as rated. That is where installation comes in, and we cover that below.

Hurricane & Compliance Performance

Laminated Impact Glass - The heart of the system. A PVB (polyvinyl butyral) interlayer is bonded between two panes of glass. Under impact from storm debris, the glass may fracture but it does not leave the frame. The film holds the broken pieces in place, keeping wind and water on the outside where they belong.

Miami-Dade NOA / FL Product Approval - Every configuration we sell carries either a Miami-Dade Notice of Acceptance or a Florida Product Approval number, issued per configuration. These are product-specific documents tied to tested assemblies. Verify the numbers on your specific quote before you submit for permit.

FBC / HVHZ Compliance - These windows are engineered to Florida Building Code High-Velocity Hurricane Zone requirements. The HVHZ designation applies to the stringent wind-borne debris region that includes all of Collier County. A window that meets HVHZ has been tested far beyond what a typical inland product sees.

TAS 201 / 202 / 203 Testing Context - HVHZ-rated products are tested under a specific protocol family: TAS 201 for large-missile impact, TAS 202 for cyclic wind-pressure loading, and TAS 203 for forced-entry resistance. Together these simulate a hurricane’s full sequence: the flying object, the battering wind cycles, and what happens after the storm when someone tries to force the opening.

Design Pressure for Your Wind Zone - We match design pressure to your wind zone, up to +/-100. Never higher. Over-engineering a window’s DP rating does not make it safer; it just costs more. We calculate what your Naples home actually requires based on building height, exposure, and opening size, then spec accordingly.

Energy Performance - Low-E and insulated glass options are available on this product. For Naples homeowners, Low-E is worth considering on east- and west-facing elevations where afternoon sun loads the glass. The impact layer does the storm work; the Low-E coating does the comfort work.

Color & Glass Options

Finish selection in Naples tends to follow the architecture. White and almond frames remain the most common choices for traditional Florida homes and condos, especially where HOA finish standards apply. Bronze frames work well on darker coastal contemporary homes in places like Moorings Park or along Gulf Shore Boulevard. Black frames have grown steadily in popularity for modern builds and remodels where the window is meant to frame the view rather than blend into the wall. Tan works nicely on softer, earthy exteriors common in parts of Golden Gate Estates.

On the glass side, clear laminated impact glass is the straightforward choice when your priority is storm protection with maximum visible light. Tinted glass helps cut glare and heat on southern exposures. Low-E insulated glass does the most for year-round energy comfort, and it pairs well with a laminated outer pane. For a Naples home with a western-facing lanai wall, that combination makes a noticeable difference in afternoon heat gain. We will walk you through trade-offs by elevation and room orientation rather than upsell you on glass you don’t need.

Installation by Winslow Windows & Doors in Naples

Here is the honest truth about impact windows: the best NOA-rated product in the world will fail if the installation is sloppy. The rating lives in the assembly as a complete system, and that system includes how the frame is anchored, leveled, and sealed to the rough opening. We do not take shortcuts on this.

Our installation process starts with a pre-install inspection of every opening. We check the rough opening dimensions, the substrate condition, and any existing water intrusion signs before a single window comes off the truck. Then we set each frame level, plumb, and square, anchored per the manufacturer’s approved method for the substrate. The perimeter is sealed with AAMA 812 low-expansion foam sealant, which fills voids without bowing the frame. Our practice follows AAMA 2400 and 2410 standards for installation workmanship.

After the window is set and sealed, we run a final water test to catch any gaps before trim goes back on. Cleanup happens the same day. In Naples, coastal exposure means salt, wind-driven rain, and humidity are working against the building envelope year-round, not just during hurricane season. The sealant detail around the frame matters every month of the year.

One more thing: if you’re pulling a permit, the building department in Naples or Collier County will likely ask for product approval documentation. We provide the NOA or Florida Product Approval numbers with your quote so your permit package is complete before we start. Improper installation compromises the NOA-rated system, and a failed inspection costs you time and money. Professional installation is not an upsell here; it is the product.

Frequently Asked Questions - Double Hung Windows

What wind zone or design pressure is the double hung window rated for? Design pressure is matched to your wind zone, up to +/-100, never higher. We calculate the required rating based on your home’s location, building height, exposure category, and opening size, then spec the correct configuration. Call (239) 899-6411 and we can run the numbers for your specific openings.

What is the lead time on double hung impact windows in Naples? Most manufacturers we work with, including PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass, are running multi-week lead times for made-to-order impact windows in Florida. The exact timeline depends on the manufacturer, glass package, and finish. We give you a written lead time on your quote so you can plan your project around it.

Does my permit require a Miami-Dade NOA or Florida Product Approval submittal? Yes, in nearly every case. Naples and Collier County building departments require product approval documentation as part of the permit package for impact windows. We provide the NOA or Florida Product Approval numbers for your specific configurations with your quote, so your permit submittal goes through cleanly. Call (239) 899-6411 and we will walk you through exactly what your jurisdiction will ask for.

Can I customize the size or configuration of my double hung windows? Yes. These windows are built to your opening dimensions, not pulled from stock. You can specify the frame material, glass package, finish color, screen type, and configuration details like mullions or divided lites where available. We measure each opening and order to fit.

How do I maintain the frames and sashes? The tilt-in sashes on both the top and bottom make cleaning the exterior glass much easier than fixed-pane products. For frame maintenance, rinse the tracks with fresh water periodically, especially if you’re within a few blocks of the Gulf, where salt accumulates. Wipe the frame finish with mild soap and water, and keep the weep holes clear so drainage works as designed. A quick rinse after heavy sea spray goes a long way in Naples.
