Product Overview - Double Hung Windows

The double hung is one of the most traditional window profiles you can put in a Florida home, and that’s exactly why so many Fort Pierce homeowners ask for it. The vertical-glide operation feels familiar, works well over kitchen sinks and along porches, and keeps sightlines clean on older ranches and newer coastal builds alike. But the version we sell and install through our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines is engineered for a different reality than the double hungs you’d find in Ohio.

Here’s what separates an impact-rated double hung from a standard one. Each sash carries laminated impact glass with a PVB interlayer. Both the top and bottom sashes tilt inward for cleaning, so you’re not leaning off a ladder or paying someone to wash second-story glass. The frame, whether aluminum or vinyl, is reinforced to carry the weight of laminated glass and hold its shape under repeated wind-pressure cycles. The locking system engages top and bottom, which matters for forced-entry resistance and for keeping the sashes from rattling in a storm.

Architecturally, the double hung suits Fort Pierce’s older neighborhoods, from Indian River Drive to the historic districts, where a casement or horizontal roller would look out of place. It also works on new construction when the homeowner wants a traditional elevation with a modern performance envelope.

Technical Specifications

Every double hung we quote in Fort Pierce is configured per opening, per elevation, and per wind zone. Nothing ships as a one-size-fits-most package. Here’s how the product breaks down.

• Frame materials: Aluminum and vinyl. Aluminum offers the slimmest sightlines and longest life in direct coastal sun. Vinyl brings strong thermal performance at a lower price point and needs less maintenance over time.
• Glass options: Laminated impact glass with a PVB interlayer as the base impact package. Low-E insulated glass can be added for energy performance. Tinted glass reduces glare and heat gain. Clear glass maximizes natural light and views.
• Finish options: White, almond, bronze, black, and tan. The dark bronze and black finishes read well on modern and Mediterranean-style homes around Fort Pierce, while white and almond remain the most common on older stucco ranches.
• Screen options: Half screen or full screen, depending on whether you want ventilation at both sashes or just the bottom.
• Design pressure: Design pressures matched to your wind zone, up to +/-100, never higher. We don’t over-spec your windows to inflate the quote, and we don’t under-spec them to win it.
• Compliance documentation: Miami-Dade NOA and Florida Product Approval numbers are available per configuration, specific to your opening sizes and glass packages. We provide the paperwork you need for permitting.

Hurricane & Compliance Performance

Laminated Impact Glass
The double hung’s glass is two panes bonded with a PVB (polyvinyl butyral) interlayer. When debris strikes, the glass may crack, but the interlayer holds the pieces in the frame. You don’t get a breach, and you don’t get the wind-pressure blowout that follows one. This is the same lamination concept used in automotive windshields, scaled for a much larger surface.

Miami-Dade NOA / Florida Product Approval
TruePane Windows & Doors supplies double hungs with Miami-Dade NOA and Florida Product Approval numbers issued per configuration. These approvals are tied to specific frame materials, glass packages, and maximum sizes. When we quote your Fort Pierce project, we verify that the exact configuration we’re selling carries valid approval documentation. You’ll see the numbers on your quote, not just a verbal assurance.

FBC / HVHZ Compliance
Fort Pierce sits in a High-Velocity Hurricane Zone, and the products we install are engineered to Florida Building Code HVHZ requirements. HVHZ is the strictest wind-borne debris region in the state, and it applies to most of coastal St. Lucie County. A window that’s “impact glass” but not HVHZ-compliant won’t pass your permit inspection here. We only install configurations that carry HVHZ-valid approvals.

TAS 201 / 202 / 203 Testing Context
HVHZ-rated impact windows are tested under the Florida testing protocol family that includes TAS 201 for large-missile impact, TAS 202 for cyclic wind-pressure loading, and TAS 203 for forced-entry resistance. These three tests collectively answer the questions that matter for Fort Pierce: can the window take a 2×4 hit, can it survive the pressure spikes that follow, and can it keep someone out after the storm. Our double hung configurations are tested under this protocol set.

Design Pressure Matched to Your Wind Zone
We don’t guess at your structural wind load. Design pressures are calculated per opening based on your home’s location, elevation, roof height, and exposure category. Our double hungs are available with design pressures matched to your wind zone, up to +/-100, never higher. Overselling a higher DP rating than your zone requires just adds cost with no performance benefit. Underselling fails inspection. We match it correctly the first time.

Energy Performance Options
Laminated impact glass provides the protection; Low-E and insulated glass packages handle the energy side. Low-E coatings reflect heat before it enters the living space, and insulated glass adds a thermal break across the cavity. For Fort Pierce homes with strong east or west sun exposure, a Low-E insulated double hung can meaningfully reduce afternoon heat gain. We’ll walk you through the glass combinations that make sense for each elevation during the quote.

Color & Glass Options

Color matters in Fort Pierce because the wrong finish fades and the wrong one fights the architecture. Our double hungs come in white, almond, bronze, black, and tan. For coastal and Mediterranean-influenced homes along the Indian River and out toward the island, black and dark bronze give a crisp, modern frame that holds up well visually against stucco and painted block. Almond and tan blend into earth-toned exteriors common in older Fort Pierce neighborhoods. White remains the default on many ranch homes because it reads clean.

Glass selection

Glass choice depends on the elevation and the room. Clear laminated impact glass maximizes natural light on shaded or northern elevations. Low-E insulated glass belongs on western and eastern exposures where afternoon sun loads the interior. Tinted glass is the right call for rooms where glare is the problem first and heat second. For most Fort Pierce homes, the practical answer is a mix: clear laminate on shaded sides, Low-E insulated on the bright ones. We quote each opening individually, so you’re not paying for Low-E on a door wall that never sees direct sun.

Installation by TruePane Windows & Doors in Fort Pierce

An impact window only performs as well as its installation. That’s not a brochure line. A NOA-rated double hung with a sloppy perimeter seal will leak water, admit wind, and potentially fail an inspection, regardless of what the product itself passed in a test lab. The moment we set your window in Fort Pierce, the installation becomes as much a part of the system as the glass.

Our process starts with a pre-install inspection of the rough opening. We check for rotted buck framing, out-of-square conditions, and water intrusion that predates the window replacement. We don’t set a new window into a rotted opening and call it done. If there’s a problem, we show it to you before work proceeds.

During installation, we set every unit level, plumb, and square. We shim the frame as the manufacturer’s installation instructions require for impact-rated units. The perimeter is sealed with AAMA 812 low-expansion foam, which air-seals without bowing the frame, and the exterior is tied back with the specified flashing and sealant detail. Our installation practice follows AAMA 2400/2410 standards, which are the accepted protocols for residential window installation.

After the window is set, we water-test the perimeter and run the sashes through full travel. We remove job debris the same day. And because Fort Pierce is an HVHZ jurisdiction, we coordinate the permit pathway with you. If your project requires a Florida Product Approval or Miami-Dade NOA submittal, we provide the documentation your permit application needs. Improper installation compromises an NOA-rated system. That’s why we handle it ourselves. No subcontractors. No day laborers. The same TruePane crew from first measurement to final cleanup.

Frequently Asked Questions - Double Hung Windows

What wind zone and design pressure is the Double Hung rated for?
Our double hung configurations are engineered to Florida Building Code HVHZ requirements, which cover Fort Pierce and most of coastal St. Lucie County. Design pressure is matched to your specific wind zone, up to +/-100, never higher. We calculate the required DP per opening based on your location, elevation, and exposure category, and we quote exactly that. No guesswork and no inflating the spec to raise the price. For the specific DP your home requires, call (772) 218-5890 and we’ll run the numbers for your address.

What is the lead time on Double Hung windows in Fort Pierce?
Lead times vary by manufacturer, finish color, and glass package. Standard white and almond units from PGT and CGI typically move faster than custom bronze or black with Low-E insulated glass. Current lead times are running around six to 10 weeks for most configs, and custom sizes or dark finishes can push toward 12. We confirm the production schedule on your quote before you commit, and we book your installation window based on the confirmed ship date. Call (772) 218-5890 if you’re working against a deadline and we’ll tell you which configurations can make it.

Does my Fort Pierce permit require a Miami-Dade NOA or Florida Product Approval submittal?
Most replacement window permits in Fort Pierce will require the product’s Florida Product Approval or Miami-Dade NOA documentation. Some jurisdictions want it included with the permit application, others only at the inspection. TruePane Windows & Doors provides the approval numbers for your specific configuration as part of your quote packet, so you’re not hunting down PDFs or emailing a manufacturer’s rep. If your HOA or structural engineer needs additional documentation, we’ll pull it for you. Call (772) 218-5890 and we’ll tell you exactly what your permit package needs.

Can I customize the size or configuration of the Double Hung?
Because the double hung is a standard profile across multiple manufacturers, we have a wide range of standard sizes available. Custom intermediate sizes are usually possible but may require an extended lead time and may not carry the same approval documentation as a standard size. If you’re working around an unusual rough opening in an older Fort Pierce home, we’ll tell you honestly whether a standard unit can be adapted or whether a custom configuration makes more sense. The approval documentation matters more than the convenience of a quarter-inch adjustment, and we won’t sell you a window that can’t pass your permit. Call (772) 218-5890 with your opening sizes.

How do I maintain the Double Hung frame and sashes?
Tilt the sashes in and wash them like any glass surface. Mild soap and water take care of the glass and the vinyl or aluminum frame. Once or twice a year, wipe down the vertical tracks with a dry cloth and check the weatherstripping for compression or tears. Salt air near Fort Pierce’s coastline can build up on aluminum frames, so an occasional rinse with fresh water helps. Don’t use abrasive cleaners on the finish, and don’t pressure-wash the window from the outside. If a sash ever binds or the lock gets stiff, call us before forcing anything. That’s a service call, not a replacement job, and (772) 218-5890 connects you to a technician.
