Single Hung Windows

Single Hung Windows in Port St. Lucie, FL | TruePane Windows & Doors

Single hung windows are the workhorse of Florida replacement window projects. You get a fixed upper sash that never moves, paired with a lower sash that lifts for airflow, all built around laminated impact glass that stays intact when debris hits it. For Port St. Lucie homeowners replacing old aluminum frames or upgrading after a storm, this profile delivers the impact rating your house needs without a floor-to-ceiling price tag. TruePane Windows & Doors installs these units across PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, and we’ve done it long enough to know what holds up on the Treasure Coast.

Product Overview - Single Hung Windows

The single hung window earns its place in Port St. Lucie homes because it solves two Florida problems at once. First, the laminated impact glass handles windborne debris without shattering into your living room. Second, the bottom sash still opens, so you keep cross-ventilation on days when the Atlantic breeze is doing its job. We install a fixed upper sash and an operable lower sash as one of the most common impact-rated replacement profiles in Florida homes, and the design makes sense for ranch houses, second-story bedrooms, and any opening where you want impact protection without losing ventilation.

These units fit the architecture of most St. Lucie West, Torino, and Tradition neighborhoods without looking like an add-on. Aluminum frames give you narrow sightlines and serious rigidity. Vinyl frames offer thermal separation that keeps the interior frame from getting hot to the touch in August. Both materials pair with laminated impact glass and meet the structural demands of hurricane-rated construction. TruePane Windows & Doors sizes and orders every unit to the rough opening, so you’re not paying for filler strips or odd trim work after the fact.

Technical Specifications

Every TruePane single hung order starts with a site measurement and ends with a unit built to the opening. The specs below are what we work from when quoting your Port St. Lucie project.

• Frame materials: Aluminum or vinyl, selected by exposure, budget, and architectural style.
• Glass options: Laminated impact glass with a PVB interlayer, Low-E insulated glass, tinted glass, or clear glass.
• Finish options: White, almond, bronze, black, or tan.
• Screen options: Half screen or full screen.
• Design pressure: Matched to your specific wind zone, up to +/-100, never higher. We don’t oversell a rating your house doesn’t need and you don’t want to pay for.
• Compliance documentation: Miami-Dade NOA and Florida Product Approval numbers available per configuration, verified on your written quote before you sign.

We carry these profiles through the PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines so your quote reflects the right product for the opening, not whatever happens to be in a warehouse.

Hurricane & Compliance Performance

Impact windows are only as good as the system behind the label. Here’s what this product delivers and what the testing actually means for your Port St. Lucie home.

Laminated Impact Glass
Two panes of glass bonded with a PVB (polyvinyl butyral) interlayer. When impact occurs, the glass cracks but the interlayer holds the fragments in the frame. The window keeps the building envelope closed during the storm cycle, which is the entire point.

Miami-Dade NOA / Florida Product Approval
Each configuration carries a Notice of Acceptance and Florida Product Approval number. These are issued per configuration, not per brand, so we verify the exact approval on your specific quote before ordering anything.

FBC High-Velocity Hurricane Zone Compliance
Engineered to Florida Building Code HVHZ requirements. Port St. Lucie sits in a wind zone that demands this level of documentation, and our permits pass because the paperwork matches the product installed.

TAS 201 / TAS 202 / TAS 203 Testing Context
HVHZ-rated products are tested under the TAS protocol family. TAS 201 covers large-missile impact, TAS 202 covers cyclic wind-pressure loading, and TAS 203 covers forced-entry resistance. The unit you buy has passed the test sequence for its configuration.

Design Pressure Matched to Your Wind Zone
Design pressures are sized for your actual wind zone, up to +/-100, never higher. Overrating a window just inflates the price without improving real-world performance for a house set back from the coast.

Energy Performance Options
Low-E insulated glass options are available for homes where afternoon sun loads are a problem. Tinted glass helps with glare on west-facing openings. Clear impact glass keeps sightlines completely neutral when visibility matters more than solar control.

Color & Glass Options

Port St. Lucie homes lean coastal and Mediterranean, which means finish choice actually moves the needle on curb appeal. White frames stay classic and clean against stucco. Almond and tan blend with earthier exteriors around Torino and PGA Village. Bronze and black frames give newer construction a sharper, more modern edge, and they read well on gray or blue-gray palettes. We’ll bring finish samples to your estimate so you’re picking in daylight, not off a screen.

On the glass side, clear impact glass is the default for homeowners who want the upgrade without changing how their house looks. Low-E insulated glass is the pick for bedrooms and west-facing living areas where the sun punishes you from noon to dusk. Tinted glass takes the edge off glare without going dark. And every option we quote starts with the PVB interlayer that makes it impact-rated in the first place.

Installation by TruePane Windows & Doors in Port St. Lucie

An impact window with a valid Miami-Dade NOA is only as good as the crew that puts it in. We’ve pulled failed units out of Port St. Lucie houses where the old install was never shimmed square, and the resulting air and water leaks voided what the homeowner thought they’d bought. That’s why our installation process is the way it is.

Every job starts with a pre-install inspection of the rough opening. We check for rotted framing, out-of-square openings, and old caulk that has to come out before new flashing goes in. Then we set the unit level, plumb, and square, which matters more than people realize. A window racked six degrees out of square binds at the sash and leaks at the corners. We don’t rush it.

Perimeter sealing follows AAMA 812 practice using low-expansion foam, and the full installation adheres to AAMA 2400/2410 standards. After install, we run a water test to confirm the seal, clean the site, and leave you with the approval paperwork for your records. In St. Lucie County and the City of Port St. Lucie, permitting in HVHZ territory requires product approvals to match the installation, so we keep your NOA and Florida Product Approval documentation in order for the inspector. Coastal exposure, wind zone, and permit submittal all factor into how we build your scope. Call (772) 362-3326 to get a free on-site measurement scheduled.

Frequently Asked Questions - Single Hung Windows

What wind zone or design pressure is the Single Hung Window rated for?
Design pressure is matched to your specific Port St. Lucie wind zone, up to +/-100, never higher. The right rating depends on where your house sits, the opening size, and the frame material. We confirm the exact design pressure for your configuration on your quote before you commit.

What is the lead time for single hung impact windows?
Lead time typically runs several weeks from order release to delivery at our Port St. Lucie shop, depending on the manufacturer line and glass configuration. We set expectations in writing when you approve the quote, so your project start date is planned around real production schedules rather than guesses.

Does this window require a Miami-Dade NOA or Florida Product Approval submittal for my permit?
Yes, your permit package in Port St. Lucie will reference the specific NOA and Florida Product Approval numbers for the configuration you buy. These are issued per configuration, so the approvals listed on your quote are what get submitted to the building department. We provide that documentation as part of the job.

Can I customize the size or configuration of my single hung windows?
Yes, within the tested approval limits for each configuration. We order to your rough opening rather than forcing stock sizes, so odd dimensions are common. If you’re replacing an existing window, we measure first and quote the exact unit your opening can support without compromising the rating.

How do I maintain the frame and track over time?
Wipe the frame and track with mild soap and water, and keep the sill track free of sand and debris. Salt air near the coast is aggressive, so an occasional rinse of the exterior frame extends the finish life. The hardware and sash balance need no special lubrication under normal residential use.
