Double Hung Windows

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

Double hung windows bring a classic, balanced look to Florida homes while doing serious work behind the scenes. Both the top and bottom sash glide vertically, and each tilts inward so you can clean the exterior glass from inside your home, a genuine advantage on a second story in Naples. For homeowners replacing original windows in Old Naples, Park Shore, or Pelican Bay, this profile preserves the traditional architecture while upgrading to laminated impact glass. TruePane Windows & Doors installs double hung impact windows throughout Collier County, and we’ve spent years refining our process for coastal wind zones, so the system performs exactly as its Florida Product Approval intends.

Product Overview - Double Hung Windows

The double hung is the most traditional operating window in American residential architecture, and in Naples it remains a top seller for good reason. The profile reads as timeless, which matters in communities with design review boards and in older neighborhoods where a modern casement or horizontal roller would look out of place. But this is not a decorative-only product. The impact-rated double hung units we install carry laminated glass engineered to hold together under debris impact, and the frames are built to resist the racking forces of hurricane wind loads.

What makes this window practical for Florida living is the tilt-in sash mechanism. Both the upper and lower sash release and swing inward, so a homeowner can wipe down the glass without a ladder. On a two-story Naples home, that’s not a nice-to-have, it’s a safety and maintenance feature. The balance system that holds the sashes in position is tuned for the weight of laminated impact glass, which is heavier than standard annealed glass. We see a lot of non-impact double hungs with sagging sashes after a few years of coastal humidity; the impact-rated hardware is built to a different standard.

Architecturally, double hungs fit traditional Florida elevations, coastal cottages, Mediterranean revival homes, and the clean-lined modern builds going up in Aqualane Shores and Golden Gate Estates. Since both sashes open, ventilation flows through the top and bottom simultaneously, which helps move warm air out and cooler air in during Naples fall and winter evenings when you’d rather open the house than run the AC.

Hurricane & Compliance Performance

Laminated Impact Glass
Two panes of glass are bonded with a PVB (polyvinyl butyral) interlayer. If debris strikes the window, the glass cracks but stays in the frame, holding the building envelope sealed. That matters in Naples, where a breached window during a storm can pressurize the home and lift the roof.

Miami-Dade NOA / Florida Product Approval
Each configuration carries its own NOA or FL Product Approval number, issued per exact size and glass package. We verify the applicable number on your specific quote, so the permit application moves cleanly through Collier County building review.

FBC / HVHZ Compliance
These windows are engineered to Florida Building Code High-Velocity Hurricane Zone requirements. HVHZ is the strictest wind-borne debris region in the state, and Naples sits squarely inside it.

TAS 201 / 202 / 203 Testing Context
HVHZ-rated products are tested under the TAS protocol family: 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 approval numbers, and it simulates what a window faces during a genuine storm event.

Design Pressure for Your Wind Zone
Design pressure is a PSF rating, not a wind speed label. We match the rating to your specific wind zone, up to +/-100 psf, and never overstate it. A window rated too low for a waterfront lot in Port Royal is a failure waiting to happen; we size it correctly from the start.

Energy Performance
Low-E and insulated glass options are available for homeowners who want impact protection plus thermal improvement. In Naples, the western exposure is the brutal one, and a Low-E insulated package on that elevation changes how the room feels by mid-afternoon.

Color & Glass Options

Finish selection in Naples usually follows the architecture. White and almond remain the most common choices for coastal cottages and older ranch homes, where a crisp neutral frame keeps the window from competing with the exterior. Black frames have grown popular on modern and transitional builds in Naples, especially paired with white or light stucco, because the contrast gives the elevation a sharper definition. Bronze works well on Mediterranean homes with clay tile accents and darker fascia. Tan tends to disappear into sand-toned stucco, a good choice when you want the window to blend rather than stand out. In high-exposure coastal locations, we recommend darker finishes carefully; Naples sun is relentless, and while these finishes are formulated for UV resistance, white and almond absorb the least heat on the frame itself.

For glass, clear laminated impact glass is the baseline: full impact protection with the truest color rendition. Tinted glass reduces glare and solar heat gain, and many Naples homeowners choose it for large eastern or western elevations where low-angle sun pours in. Low-E insulated glass adds a thermal barrier along with the impact laminate; it’s the right call when a room faces direct afternoon sun or when you’re trying to reduce AC load. Laminated plus insulated means a thicker glass package, so we confirm the frame is spec’d to carry the added weight before ordering.

Installation by TruePane Windows & Doors in Naples

A window that passes TAS 201 impact testing in a lab still fails in the real world if it’s installed poorly. In Naples, the two biggest installation risks are water intrusion from wind-driven rain and improper anchoring that allows the frame to flex under cyclic loading. A gap in the perimeter seal or a shim placed wrong can turn a $4,000 window into a leak path and a permit problem. That’s why TruePane Windows & Doors treats installation as part of the product system.

Our process starts with a pre-install inspection of the rough opening. We check the condition of the buck, the substrate, and the existing waterproofing before we order anything. During install, we set every unit level, plumb, and square, then secure it per manufacturer anchoring schedules for the NOA-rated configuration. The perimeter gets AAMA 812 low-expansion foam sealant, which creates a continuous air and water barrier without distorting the frame. This practice follows AAMA 2400 and 2410 standards, the protocol family for window installation detailing. After the frame is anchored and sealed, we run a water test on the installation, then clean the glass, remove job debris, and walk the interior and exterior with the homeowner.

Naples-specific factors matter here. Coastal exposure means we use stainless hardware and fasteners where salt spray is a concern. Wind zones shift from neighborhood to neighborhood; a home on a canal in Royal Harbor can carry a different design pressure requirement than a home a mile inland in Victoria Park. We check the specific wind zone for the address before confirming the window package, and we know the permitting rhythm in Collier County well enough to flag NOA submittal requirements early.

Frequently Asked Questions - Double Hung Windows

What wind zone / design pressure is the double hung window rated for?
The design pressure is matched to your specific wind zone, up to +/-100 psf, never higher. Coastal Naples addresses often require higher ratings than inland lots, and we confirm the exact requirement for your property before we order. Call (239) 326-9942 and we’ll check the wind zone for your address.

What is the lead time on double hung impact windows in Naples?
Most double hung impact configurations run four to seven weeks from approved drawings to delivery, depending on the glass package and finish. Custom sizes and low-volume finishes can push longer. We lock the order once your approval is signed, so the timeline is predictable. Call (239) 326-9942 to confirm current lead times for your configuration.

Does my permit require a Miami-Dade NOA or Florida Product Approval submittal?
Yes. In Collier County and the City of Naples, impact windows must show either a Miami-Dade NOA or a Florida Product Approval number matching the exact configuration you’re installing. We provide the applicable number with your quote and include the documentation in the permit package. Call (239) 326-9942 if your contractor or building department has asked for this paperwork.

Can I customize the size or configuration of my double hung windows?
Within the tested size range of the NOA-rated configuration, yes. Width and height adjustments, glass package changes, and finish selection all affect the approval number, which is why we confirm feasibility before promising a size. Custom sizes outside the tested range may not carry approval. Call (239) 326-9942 with your rough opening dimensions and we’ll tell you what’s possible.

How do I maintain the frame and sashes on a Naples double hung impact window?
Wipe the frame tracks and sill with a damp cloth every quarter to clear salt residue and sand, which accumulate faster near the coast. The tilt-in sash mechanism lets you clean the exterior glass from inside. Don’t pressure wash the windows; high pressure can force water past the frame seals. If a balance mechanism feels stiff, call us to inspect before it becomes a bigger issue.
