Single Hung Windows

Single Hung Windows in Fort Lauderdale, FL | Winslow Windows & Doors

Single hung windows remain one of the most requested impact-rated profiles we install in Fort Lauderdale homes. The design is straightforward: a fixed upper sash that never moves, and a lower sash that slides up to ventilate. What makes the impact version different is the laminated glass and the reinforced frame engineering behind it. We install these across PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, and we match the configuration to your specific wind zone, not a generic “Florida” rating. If you’re pricing a replacement or planning new construction in Fort Lauderdale, call (904) 913-5886 and we’ll walk through the numbers with you.

Product Overview - Single Hung Windows

A single hung window has a fixed upper sash and an operable lower sash in laminated impact glass. That combination is one of the most common impact-rated replacement profiles in Florida homes, and for good reason. The fixed upper sash removes a failure point. Only one moving sash means fewer seals to maintain, fewer balance mechanisms to wear out, and less air infiltration over time compared to a double hung.

In Fort Lauderdale, where we replace windows in neighborhoods like Victoria Park, Rio Vista, Coral Ridge, and Sailboat Bend, the architectural fit matters as much as the engineering. Single hung units read as clean and traditional. They suit the ranch homes, mid-century builds, and 1960s-1980s concrete block houses that dominate this market. The sightlines are slim enough to preserve the original look, but the frame is built to carry laminated impact glass without sagging.

We spec these in aluminum or vinyl, depending on the home. Aluminum is the default for many Fort Lauderdale homeowners because it handles coastal salt air well and allows for thinner frame profiles. Vinyl offers a different thermal profile and is common in inland sections of the city. Both can be configured to meet Miami-Dade NOA and Florida Product Approval requirements. The key is that the frame, glass, and hardware are approved as a system, not as separate parts. Winslow Windows & Doors only installs configurations where that system approval exists on paper for your specific size and design pressure.

Technical Specifications

• Frame materials: Aluminum or vinyl, selected for the specific elevation and exposure of your Fort Lauderdale property.
• Glass options: Laminated impact glass with a PVB interlayer, Low-E insulated glass, tinted glass, or clear glass. Combinations available depending on the line.
• Finish options: White, almond, bronze, black, and tan. Powder-coated on aluminum; color-matched on vinyl lines.
• Screen options: Half screen for lower-sash ventilation, or full screen for a uniform exterior look.
• Design pressure range: Matched to your wind zone, up to +/-100. We never over-spec a unit beyond what the elevation actually requires.
• Compliance documentation: Miami-Dade NOA and Florida Product Approval numbers are issued per configuration, not per product family. We verify the exact numbers on your written quote.

Hurricane & Compliance Performance

Laminated Impact Glass – The glass in these units is built with a PVB (polyvinyl butyral) interlayer sandwiched between two panes. When debris strikes, the glass may crack, but the interlayer holds the glass in the frame. The opening stays sealed. Wind, rain, and windborne debris stay outside where they belong. That’s the entire point of impact-rated glazing in a Fort Lauderdale hurricane.

Miami-Dade NOA / Florida Product Approval – Every configuration we sell carries either a Miami-Dade NOA (Notice of Acceptance) or a Florida Product Approval number, or both. These numbers are issued per configuration: specific frame material, specific glass make-up, specific size range. Not per brand. We provide the actual approval numbers on your quote so your permit application is accurate the first time.

FBC / HVHZ Compliance – Single hung units from Winslow Windows & Doors are engineered to Florida Building Code (FBC) High-Velocity Hurricane Zone (HVHZ) requirements. Fort Lauderdale sits inside the HVHZ, which carries the strictest wind-load provisions in the state. Products rated for the HVHZ are tested differently than products for inland Florida.

TAS 201 / 202 / 203 Testing Context – HVHZ-rated products are tested under a specific protocol family. TAS 201 covers large-missile impact, meaning a piece of lumber fired at the glass. TAS 202 covers cyclic wind-pressure loading, which simulates the repeated pressure and suction cycles of a hurricane. TAS 203 covers forced-entry resistance. These three tests, passed together, are what separate certified impact windows from ordinary windows with laminated glass added.

Design Pressure for Your Wind Zone – Design pressure (DP) is a PSF rating, not a wind speed. It measures how much positive and negative pressure a window can take before structural failure. We spec design pressures matched to your wind zone, up to +/-100, and never higher. A window on a sheltered first-floor elevation in Fort Lauderdale does not need the same DP as a third-floor corner unit facing the Atlantic. Over-spec costs money. Under-spec fails inspection and puts the home at risk. We get it right by measuring, not estimating.

Energy Performance Options – Impact glass does not automatically mean high energy performance. We offer Low-E insulated glass configurations and tinted options for homeowners who want to address heat gain and UV exposure. Clear laminated impact glass meets code but does little for solar heat. If your Fort Lauderdale rooms face west or south, Low-E or tinted options are worth a close look.

Color & Glass Options

Fort Lauderdale architecture swings between crisp white coastal, warm Mediterranean, and mid-century modern. The five finish options we offer, white, almond, bronze, black, and tan, cover those palettes. White and almond read clean and bright, which suits the coastal cottages and ranch homes in neighborhoods like Croissant Park and Poinsettia Heights. Bronze and black are popular for homes with darker trim, Bahama-style accents, or a more contemporary look in Victoria Park and Colee Hammock. Tan works well on homes with natural stone or stucco earth tones.

On the glass side, clear laminated impact glass is the most budget-conscious route and the closest to what many older Fort Lauderdale homes already have. Tinted glass cuts glare and adds privacy, though it dims the room. Low-E insulated glass is the strongest choice for energy performance, reflecting heat while keeping visibility. An insulated unit with Low-E and a laminated outer pane gives you both impact protection and meaningful thermal resistance. We spec glass by elevation: a shaded north-facing window has different needs than a full-sun east exposure catching morning heat off the Intracoastal.

Installation by Winslow Windows & Doors in Fort Lauderdale

An NOA-rated or Florida Product Approved single hung window only performs as rated if the installation matches the tested assembly. A window that’s out of level, shimmed wrong, or sealed with the wrong material will leak, bind, or fail under pressure. We see improper replacements in Fort Lauderdale all the time: windows set with drywall screws, gaps stuffed with fiberglass, flashing missing entirely. That’s not an installation. It’s a liability.

Our process starts with a pre-install inspection of the opening. We check the rough opening dimensions, the condition of the existing buck or wood frame, and any signs of water intrusion from the old unit. Then we set the window level, plumb, and square, using structural shims and fasteners appropriate for concrete block or wood frame construction. The perimeter gets sealed with AAMA 812 low-expansion foam, which seals without bowing the frame. We follow AAMA 2400 and 2410 installation practice standards throughout the job.

Fort Lauderdale brings specific challenges. Coastal exposure means salt air is attacking fasteners and flashings before the window even goes in. Wind zone requirements change by address, and the building department will ask for your NOA or Florida Product Approval documentation before issuing a permit. We handle that paperwork as part of the job. After the unit is set and sealed, we run a water test on the installation and inspect the interior before cleanup. You get a window that works, documents that pass inspection, and an installation that won’t fail the first time a Category 2 storm passes through.

Frequently Asked Questions - Single Hung Windows

What wind zone / design pressure is the single hung window rated for? The design pressure is matched to your specific wind zone and elevation, up to +/-100 PSF. We never sell a higher DP rating than the home actually requires, and we never sell a lower one. Your written quote will state the exact DP rating for each opening, sized to your Fort Lauderdale address.

What is the lead time for single hung windows? Lead times vary by manufacturer and configuration. PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass all run on different production schedules, and custom sizes or specific finish colors take longer than stock configurations. When you request a quote, we’ll give you a current production timeline from the manufacturer so you can plan your project around it. Call (904) 913-5886 for today’s timeframes.

Does a single hung window require a Miami-Dade NOA or Florida Product Approval submittal for my permit? Yes. Fort Lauderdale Building Services will require approval documentation for any impact-rated window installation in an HVHZ jurisdiction. The NOA or Florida Product Approval number is specific to your window configuration, so it can’t be guessed or copied from another project. Winslow Windows & Doors includes the correct approval numbers on your quote and in your permit submittal package.

Can I customize the size or configuration of a single hung window? Within the ranges listed on the product approval documents, yes. Each manufacturer publishes approved size ranges, and anything outside those ranges cannot be used in an HVHZ installation. We take field measurements and match your openings to approved configurations. If an opening doesn’t fit an approved size, we’ll tell you before you order, not after delivery.

How do I maintain the frame and the track? For both aluminum and vinyl frames, the maintenance is mostly cleaning the track and keeping the weep holes clear. Fort Lauderdale’s salt air and seasonal rains mean debris builds up in the bottom track faster than inland. Rinse the track every few months, keep the weep holes open, and wipe the gaskets with a non-petroleum cleaner. If the sash ever gets stiff or the balance feels off, call us before forcing it. Forced sashes crack glass and bend frames.
