Double Hung Windows

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

Double hung windows bring a familiar, traditional look to Tampa homes, with two sashes that glide vertically for ventilation from the top, the bottom, or both at once. In Florida, that classic profile has to do more than look right. It has to hold up under hurricane-force wind, wind-driven rain, and flying debris. TruePane Windows & Doors installs impact-rated double hung windows across Tampa, from Palma Ceia bungalows to Davis Islands waterfront homes, so you get the look you want and the protection the Florida Building Code demands. We carry and install these products across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines. Call (813) 320-9346 to talk through your project.

Product Overview - Double Hung Windows

Double hung windows are the classic vertical-glide design: two operable sashes, one above the other, each sliding in its own track. On a quiet Tampa afternoon, you can drop the top sash a few inches and let warm air out while the bottom stays closed. Both sashes tilt inward for cleaning, which matters when you live near Bayshore Boulevard and want to wipe salt haze off the glass without a ladder.

What makes this version different from a builder-grade double hung is the impact engineering. These units carry laminated impact glass with a PVB interlayer, the same general category of protection used in Florida’s High-Velocity Hurricane Zone. The frame is available in aluminum or vinyl, and the hardware, balances, and interlocks are built for the cycle testing that Miami-Dade product approval requires. The profile reads traditional, not industrial. From the curb, it looks like a proper double hung. From an engineering standpoint, it’s a rated opening protection system.

This is the window Tampa homeowners choose when they want to preserve the architecture of an older home in Seminole Heights, Hyde Park, or West Tampa while bringing the openings up to current code. TruePane Windows & Doors has installed this product in wood frame and block construction alike, and we match the installation method to the wall condition and wind zone.

Technical Specifications

Here’s how this double hung breaks down, in plain terms. Exact sizes and design pressure numbers get locked in on your quote, because they’re tied to the opening dimensions and your specific wind zone.

• Frame materials: Aluminum and vinyl, chosen for corrosion resistance in Tampa’s coastal air and low maintenance through Florida summers.
• Glass options: Laminated impact glass with a PVB interlayer, Low-E insulated glass, tinted glass, and clear glass. Glass packages vary by thermal and light goals.
• Finish options: White, almond, bronze, black, and tan. These are the colors that sit naturally on Tampa’s mix of Florida ranch, Mediterranean, and coastal vernacular homes.
• Screen options: Half screen or full screen, so you can ventilate from the top sash while keeping bugs out.
• Design pressure: Matched to your wind zone, up to +/-100. Never higher than what your opening actually requires.
• Compliance documentation: Miami-Dade NOA and Florida Product Approval numbers are issued per configuration. Your quote lists the exact approvals for the sizes and glass you order.
• Code compliance: Engineered to Florida Building Code High-Velocity Hurricane Zone requirements.

Hurricane & Compliance Performance

Every claim below ties to a specific testing protocol or code path. If you’re pulling permits in the City of Tampa or unincorporated Hillsborough County, this is the language your plans examiner is looking for.

Laminated Impact Glass
The impact-rated glazing uses a polyvinyl butyral (PVB) interlayer bonded between glass lites. Under impact, the glass may fracture, but the interlayer holds the pieces in the frame, keeping the building envelope closed and wind-driven rain out. That’s the core of what makes an impact window an impact window.

Miami-Dade NOA & Florida Product Approval
Each configuration of this double hung carries its own Notice of Acceptance and Florida Product Approval numbers. These are not one-size-fits-all documents. The approvals are tied to specific frame material, glass makeup, and maximum size, which is why we verify the exact numbers on your written quote.

FBC / HVHZ Compliance
The product is engineered to Florida Building Code High-Velocity Hurricane Zone requirements. Tampa sits inside the HVHZ wind-borne debris region. That means the governing requirement is not a suggestion or a coastal add-on. It applies to the whole city.

TAS 201, TAS 202, and TAS 203 Testing Context
These are the test protocols in the family HVHZ-rated products are evaluated under. TAS 201 covers large-missile impact. TAS 202 covers cyclic wind-pressure loading, which simulates the push-pull of a hurricane, not a single gust. TAS 203 covers forced-entry resistance. When a product carries a Miami-Dade NOA, it has been through this protocol family.

Design Pressure for Your Wind Zone
We size the design pressure to the wind zone your home actually sits in, up to +/-100. We don’t upsell you to a higher pressure rating than your openings require, and we don’t undersize to hit a price. The structural load path on a double hung includes the frame, the interlocks, and the anchors, so the whole assembly has to work together.

Energy Performance Options
Low-E and insulated glass packages are available for the double hung line. In Tampa, the Low-E coating cuts solar heat gain through the glass while still giving you daylight. An insulated Low-E setup makes the most sense on air-conditioned rooms with significant west or south exposure.

Color & Glass Options

The frame finish does real work on a Tampa home. White and almond read clean on the Florida ranch and coastal cottage styles you see throughout South Tampa and Carrollwood. Bronze and black add contrast on Mediterranean and Spanish revival homes, especially with stucco or barrel-tile details. Tan works well where the trim wants to recede against warm beige or coral exteriors.

On the glass side, laminated impact glass is the baseline requirement for hurricane protection. From there, the choice is about daylight, heat, and privacy. Tinted glass reduces glare and solar gain, which matters on bedrooms that catch the late afternoon sun. Low-E insulated glass improves thermal performance across the whole opening. Clear laminated impact glass is the right call when you want the most natural light and aren’t fighting a heat problem. We’ll walk you through the tradeoffs for each opening during the estimate.

Installation by TruePane Windows & Doors in Tampa

A Miami-Dade NOA is only as good as the installation behind it. A rated window that’s set out of square, anchored short, or sealed with the wrong product doesn’t perform like the test report says it will. That’s why we treat installation as part of the rated assembly, not a separate step.

Our process starts with a pre-install inspection of the rough opening. We’re looking at the condition of the framing, any existing water damage, and how the old window was flashed. In an older Tampa home, that’s where the real problems hide, and you want them found before a new window goes in.

The new unit is set level, plumb, and square, with shims and anchors per the approved anchoring schedule. We don’t eyeball it. We check the frame in both planes before the first fastener goes in. The perimeter gets a low-expansion foam sealant in line with AAMA 812 practice, followed by the full sealing and flashing detail the opening requires. Our installation methods follow AAMA 2400/2410 practice for window installation.

After the window is secured and sealed, we do a water test on the install and clean the glass, frame, and sill. Before we start, we’ll also talk through the permitting path for your address. Tampa and Hillsborough County permits for HVHZ openings typically require the Product Approval documents for the exact units you’re installing. We provide those documents for submission, and we can pull the permit for you if you’d prefer we run the full process.

The coastal exposure on Davis Islands and along Bayshore means more salt in the air and more wind load on the glass. That’s precisely the kind of site that rewards careful flashing and anchoring. TruePane Windows & Doors has installed impact-rated openings all over Tampa, and we treat every opening like it’s going to get tested.

Frequently Asked Questions - Double Hung Windows

What wind zone or design pressure is the Double Hung rated for?
Design pressure is matched to your specific wind zone, up to +/-100. The exact rating for your opening depends on the size, frame material, and glass package you choose, and it’s confirmed on your written quote with the corresponding Miami-Dade NOA and Florida Product Approval documents. Call (813) 320-9346 and we’ll determine the right rating for your home’s location.

What is the lead time for a Double Hung order?
Lead time varies by manufacturer and configuration. A standard white aluminum double hung with laminated impact glass moves faster than a custom black vinyl unit with Low-E insulated glass and a full screen. We give you a written production window when you approve the quote, and we schedule installation around your home, not the other way around.

Does this product require a Miami-Dade NOA or Florida Product Approval submittal for my permit?
Yes. Any impact-rated window installed in an HVHZ jurisdiction like Tampa requires the Product Approval documents for the exact units going into the openings. The NOA and Florida Product Approval numbers are issued per configuration, so the paperwork has to match the sizes, glass, and frame material on your order. TruePane Windows & Doors provides the correct approval documents for your permit package.

Can I customize the size or configuration?
Most openings are custom-sized. Double hung windows work in standard and odd-size rough openings alike, within the limits of the approved pressure ratings. If an opening is too wide for a double hung at your design pressure, we’ll tell you honestly and show you alternatives that meet code. We won’t put a window in an opening it isn’t approved for.

How do I maintain the frame?
Wash the frame with mild soap and water, keep the tracks clear of debris, and wipe down the weatherstripping with a damp cloth. In Tampa’s salt air, it’s worth rinsing aluminum frames on coastal homes a few times a year. The tilt-in sashes let you clean the exterior-facing glass from inside, which is the whole point of a double hung on a second floor. If a balance or latch ever acts up, call (813) 320-9346 and we’ll take a look.
