Single Hung Windows

Single Hung Windows in Palm Beach, FL | Winslow Windows & Doors

Single hung windows are one of the most common replacement profiles we install in Palm Beach County homes, and for good reason. The design pairs a fixed upper sash with an operable lower sash, both glazed in laminated impact glass. That means you get the clean sightlines and lower cost of a traditional vertical slider, but with the storm protection a coastal Florida home actually needs. Winslow Windows & Doors has installed impact-rated single hung windows across Palm Beach, from West Palm Beach to Lake Worth Beach to Boca Raton, for years.

Product Overview - Single Hung Windows

A single hung window operates from the bottom sash only. The top sash is fixed in place and never moves, which creates a simpler, tighter assembly than a double hung. For Florida homeowners, that simplicity matters. Fewer moving parts means fewer points where wind-driven rain can work its way in during a storm. In Palm Beach, where afternoon thunderstorms roll through hard and fast in summer, that’s a real advantage.

The impact-rated version of this profile uses laminated glass in both the fixed upper sash and the operable lower sash. The bottom sash tilts in for cleaning, which is a practical detail when you’re dealing with second-story windows or hard-to-reach openings on a two-story Palm Beach home. Architecturally, single hung windows read as classic and understated. They fit Mediterranean Revival homes in El Cid, Mid-Century Modern houses in Palm Beach Gardens, and newer construction in Wellington equally well. The proportions are vertical, the lines are clean, and the hardware is minimal.

Winslow Windows & Doors supplies this window through our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, which gives us real flexibility on frame material, finish color, and glass package. You’re not locked into one manufacturer’s version of what a single hung should be.

Technical Specifications

Here’s what you can specify on a single hung impact window from Winslow Windows & Doors. Every configuration is quoted per opening, so the numbers below reflect the full range we can order.

• Frame materials: Aluminum or vinyl. Aluminum is the standard choice for coastal Palm Beach spec homes and condos; vinyl offers a warmer feel and lower thermal transfer for inland neighborhoods like Royal Palm Beach or Loxahatchee.
• Glass options: Laminated impact glass with a PVB interlayer (the storm-rated core), Low-E insulated glass for energy performance, tinted glass for glare and heat control, and clear glass for maximum natural light.
• Finish colors: White, Almond, Bronze, Black, and Tan. These cover the palette you see across Palm Beach County, from white coastal cottages to dark bronze Modern homes.
• Screen options: Half screen for lower-sash ventilation only, or full screen for complete opening coverage when the lower sash is open.
• Design pressure: Matched to your specific wind zone, up to +/-100, never higher. We don’t oversell pressure ratings you don’t need.
• Compliance documentation: Miami-Dade NOA and Florida Product Approval numbers available per configuration. We verify the exact numbers on your quote.

Hurricane & Compliance Performance

Single hung impact windows live or die by how they perform under storm loading. Here’s what the Winslow Windows & Doors product delivers, in plain terms.

Laminated Impact Glass
Two panes of glass are bonded together with a PVB interlayer. When debris hits the window, the glass may crack but it stays in the frame. That’s the entire point: your home envelope stays sealed even if the glass is struck. We see this make the difference in Palm Beach County storms, where a broken window can lead to pressurization and roof failure.

Miami-Dade NOA / FL Product Approval
Every configuration we quote carries either a Miami-Dade Notice of Acceptance or a Florida Product Approval number, depending on the specific product line and size. These numbers are issued per configuration, not per product family, so we verify the exact approval on every quote we write. That documentation is what your building department checks when you pull a permit in Palm Beach, West Palm Beach, or any HVHZ jurisdiction.

FBC / HVHZ Compliance
The product is engineered to Florida Building Code High-Velocity Hurricane Zone requirements. HVHZ is the strictest wind standard in the state, and it governs Palm Beach County. When a product is HVHZ-compliant, it has been designed and tested for the wind pressures and debris loads specific to our coastline. This isn’t a marketing badge; it’s a code requirement for legal installation here.

TAS 201 / TAS 202 / TAS 203 Testing Context
HVHZ-rated products are tested under a specific protocol family. TAS 201 covers large-missile impact, meaning the window gets hit with a projectile designed to simulate wind-borne debris. TAS 202 tests cyclic wind-pressure loading, which simulates the repeated gusts of a hurricane. TAS 203 evaluates forced-entry resistance. These three standards are the backbone of HVHZ product evaluation, and our single hung configurations are tested under them.

Design Pressure for Your Wind Zone
We match design pressure to the wind zone of your specific home, up to +/-100. The key phrase is “your wind zone.” A house on the barrier island in Palm Beach has different requirements than a home 15 miles inland in Royal Palm Beach. We don’t sell the same pressure rating to everyone, because building code doesn’t apply the same pressure rating to everyone. We’ll calculate what your location actually requires and quote that.

Energy Performance
Single hung impact windows can be glazed with Low-E insulated glass instead of standard laminated impact glass. That upgrade cuts solar heat gain, which matters in Palm Beach where cooling season runs nine months a year. Tinted glass is another option for west-facing elevations that take direct afternoon sun. We’ll walk you through what makes sense per elevation of your home.

Color & Glass Options

The frame finish is the first thing people notice from the street, and single hung windows give you five real options: White, Almond, Bronze, Black, and Tan. In Palm Beach, we see white and almond dominate on older coastal homes and condominiums, where the finish needs to blend with stucco and trim. Black and bronze have become the go-to on newer construction and renovated Mid-Century homes in neighborhoods like SoSo and Grandview Heights. Tan works well on Tuscan-style homes in Wellington and Palm Beach Gardens.

Glass selection gets more personal. Clear laminated impact glass gives you the truest view and the most natural light, which is what most people want on east-facing windows overlooking the Intracoastal. Tinted glass cuts glare and heat gain, and it adds a level of daytime privacy. Low-E insulated glass is the best choice if your single hung windows face west or south and you’re tired of rooms heating up in the afternoon. Every option we quote is available in the impact-rated laminated configuration that Palm Beach County code requires.

Installation by Winslow Windows & Doors in Palm Beach

An HVHZ-rated window is only as good as its installation. The NOA rating assumes the window is installed correctly into a properly prepared opening. If the frame isn’t level, plumb, and square, or the perimeter seal fails, the approval means nothing. That’s why we take installation on our own shoulders instead of handing it off to someone else.

Our process in Palm Beach starts with a pre-install inspection of every opening. We check the existing frame, the rough opening dimensions, and the condition of the surrounding wall. Then we set each window level, plumb, and square, shim as needed, and secure it per the manufacturer’s HVHZ fastening schedule. We seal the perimeter with AAMA 812 low-expansion foam, which fills voids, blocks air movement, and creates a water-resistive barrier. The entire installation follows AAMA 2400 and 2410 practice, which are the industry standards for window installation craftsmanship.

After installation, we run a water test on the opening and then complete interior and exterior cleanup. We also handle permit awareness for HVHZ jurisdictions: Palm Beach, West Palm Beach, Boca Raton, Delray Beach, and every municipality in the county have their own submittal nuances. We know what each building department wants to see, and we make sure your NOA documentation matches your permit application. Coastal exposure, wind zone calculations, and code-specific fastening all factor into how we quote and install your windows. This is not a product to buy online and hand to a handyman.

Frequently Asked Questions - Single Hung Windows

What wind zone / design pressure is the Single Hung Window rated for?
We match design pressure to your specific wind zone, up to +/-100, and never higher than what your location requires. Palm Beach County spans multiple wind zones depending on distance from the coast and building height. During your free on-site measurement, we’ll confirm your home’s exposure category and quote the correct pressure rating for your permit.

What is the lead time for single hung impact windows?
Lead time varies by manufacturer and configuration. Our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines have different production schedules, and custom sizes or finishes can add time. We’ll give you a realistic window when we write your quote. Call (561) 782-7525 and we’ll check current production times for the specific setup you’re interested in.

Does my permit require a Miami-Dade NOA or Florida Product Approval submittal?
Yes. Every HVHZ jurisdiction in Palm Beach County, including the Town of Palm Beach, West Palm Beach, and Boca Raton, will require a copy of the Miami-Dade NOA or Florida Product Approval for each window configuration you install. We provide the correct documentation with your quote and we’ll help you confirm it matches what your permit application lists. Call (561) 782-7525 and we’ll walk you through what your specific municipality asks for.

Can I customize the size or configuration of a single hung impact window?
Yes. These windows are ordered per opening, not pulled from stock. Width and height are sized to your rough opening, and you choose frame material, finish color, glass type, and screen style. Unusual openings, like narrow sidelight windows or oversized picture openings with an operable lower sash, are quoted case by case. Estimates are free.

How do I maintain the frame?
Clean the frame and glass with mild soap and water, and keep the sill track clear of sand and debris. In Palm Beach, salt air is the biggest long-term concern, especially for homes within a mile of the ocean. Rinsing the frames periodically with fresh water extends the finish life. The lower sash tilts in for cleaning, which makes interior and exterior glass access simple on second-story windows.
