AfterSingle Hung Windows in Palm Beach, FL | Winslow Windows & Doors
Single hung windows are the quiet workhorses of Florida residential construction. The upper sash stays fixed while the lower sash glides up and down, which means fewer moving parts, fewer seal points, and a tighter envelope than a double hung. In Palm Beach, where wind-driven rain and flying debris are seasonal facts of life, that simplicity translates directly into resilience. Winslow Windows & Doors supplies and installs single hung impact windows across PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass product lines, always matched to the wind zone of the specific home and installed to hold its NOA rating. Call (561) 831-7863 to talk through your project.
Product Overview - Single Hung Windows
A fixed upper sash and an operable lower sash in laminated impact glass make this one of the most common impact-rated replacement profiles in Florida homes, and for good reason. The fixed top sash eliminates one set of weatherstripping channels entirely. That’s one less path for water intrusion during a storm, one less track to maintain, and one less point of failure over decades of coastal humidity. The lower sash still gives you the ventilation you want on a January afternoon when the Palm Beach air finally drops below 75 degrees.
Architecturally, single hung windows suit the clean vertical lines you see throughout Palm Beach: mid-century ranches in Lake Worth, 1970s two-story colonials in West Palm Beach, and newer stucco builds in Royal Palm Beach that need an impact upgrade without a full redesign. The profile reads narrow and crisp from the street, which fits the understated Florida aesthetic better than bulkier frame systems. For homes where curb appeal matters as much as code compliance, it’s a forgiving product.
The frame materials we work with include aluminum and vinyl. Aluminum carries the structural rigidity that bigger openings demand and takes a baked-on finish beautifully. Vinyl offers inherent thermal breaks and a lower maintenance profile for homeowners who never want to think about their windows again. Both can be engineered to the same HVHZ standard.
Technical Specifications
Every single hung window we quote is built to order for the specific opening and wind zone. Here is what the product platform includes:
- Frame materials: Aluminum or vinyl, selected for the opening size and exposure
- Glass options: Laminated impact glass with PVB interlayer, Low-E insulated glass for energy performance, tinted glass for solar control, or clear glass for maximum light transmission
- Finish colors: White, Almond, Bronze, Black, and Tan
- Screen options: Half screen or full screen, depending on ventilation preference and sill configuration
- Design pressure: Matched to your wind zone, up to +/-100, never higher
- Sizing: Custom widths and heights fabricated per opening
- Compliance documentation: Miami-Dade NOA and Florida Product Approval numbers available per configuration
We will walk you through the options that matter for your specific Palm Beach location, because a beachfront condo on South Ocean Boulevard and a canal home in Boynton Beach do not face the same wind pressures.
Hurricane & Compliance Performance
Laminated Impact Glass – The glass in these windows is built with a PVB interlayer. When wind-borne debris hits, the glass may crack but the interlayer holds the fragments in the frame. Your envelope stays sealed, your interior stays dry, and the window continues doing its structural job through the remainder of the storm.
Miami-Dade NOA / FL Product Approval – Every configuration we quote carries a Miami-Dade Notice of Acceptance or Florida Product Approval number, issued per configuration. We provide the specific documentation for your window size and sill condition with your quote, which your permitting jurisdiction in Palm Beach County will require.
FBC/HVHZ Compliance – The entire platform is engineered to Florida Building Code High-Velocity Hurricane Zone requirements. That is the standard Palm Beach County enforces. If a window does not meet it, it does not get permitted here, period. This product line does.
TAS 201/202/203 Testing Context – HVHZ-rated products are tested under a 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 tests simulate what actually happens during a hurricane, not a calm afternoon with a static load.
Design Pressure Matched to Your Wind Zone – We match design pressure to your specific wind zone, up to +/-100, never higher. Some window companies oversell pressure ratings to justify an upcharge. We will not. The rating your home actually needs is the one we quote, and the engineering paperwork backs it up.
Energy Performance Options – Low-E and insulated glass upgrades are available for homeowners who want more than storm protection. A Low-E interlayer cuts solar heat gain on western exposures, which matters in Palm Beach where afternoon sun punishes west-facing bedrooms and living rooms from March through October.
Color & Glass Options
Palm Beach architecture runs the spectrum from white stucco Mediterranean villas to bronze-trimmed coastal contemporary homes, and the finish palette this product offers covers all of it. White stays the default for most Florida homes because it disappears into light stucco walls and never fights the architecture. Almond warms up beige and travertine exteriors without reading dated. Tan does the same with slightly more depth. Bronze and Black frame the glass sharply and give newer construction a modern edge, especially against white or gray facades. All five finishes are baked-on, not painted, so they hold up to Palm Beach sun without chalking or fading.
Glass selection depends on orientation. Clear impact glass preserves the natural light and water views that people pay a premium for in Palm Beach. Tinted glass knocks down glare on east-facing breakfast rooms and west-facing patios. Low-E insulated glass is the play for rooms where air conditioning costs are felt hardest, typically upstairs bedrooms and big glass walls with no shade. Half screens or full screens finish the package, depending on how often you actually leave the sash open.
Installation by Winslow Windows & Doors in Palm Beach
An impact window is only as strong as the perimeter seal around it. We have pulled NOA-rated windows out of Palm Beach homes where the previous installer left gaps at the sill, skipped the foam perimeter entirely, or shimmed the frame so badly the sash bound within a year. A window that carries a Miami-Dade NOA will still leak if the installation does not match the engineering intent. That is why our installation practice follows AAMA 2400 and 2410 standards and we seal the perimeter with AAMA 812 low-expansion foam, which fills gaps without bowing the frame and provides a continuous air and water barrier around the opening.
Every installation starts with a pre-install inspection of the rough opening. We check for wood rot, termite damage, bowed headers, and out-of-square openings before the old window ever comes out. Palm Beach’s coastal air accelerates corrosion and rot in ways builders in inland Florida never see, and we would rather fix the opening right the first time than hide a problem behind a new window. The new unit is set level, plumb, and square, shimmed at the proper points, and anchored per the manufacturer’s requirements for the wind zone. After the foam cures, we run a final water test on the perimeter, install interior trim or returns as needed, and leave the job site clean.
Permitting in Palm Beach is another layer we handle carefully. HVHZ jurisdictions like Palm Beach County, the town of Palm Beach, and West Palm Beach require product approval numbers on the permit submittal, and the window must be installed by a licensed contractor who pulls the permit. We have gone through this process hundreds of times for homeowners from Jupiter to Delray Beach, and we know exactly what the building department wants to see.
Frequently Asked Questions - Single Hung Windows
The design pressure is matched to your specific wind zone, up to +/-100, never higher. Your home’s location in Palm Beach County, its exposure category, and the height above grade all factor into the required rating. We determine the correct design pressure for your address and provide the engineering documentation with your quote. Call (561) 831-7863 for an evaluation of your specific property.
Lead times vary by manufacturer and finish, but most single hung impact window orders in Palm Beach run several weeks from final measurement to delivery. PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass all fabricate to order for the specific opening size, which means windows are built for your home, not pulled from a warehouse. We will give you a realistic timeline when we quote the project so you can plan around it.
Yes. Palm Beach County and its municipalities are High-Velocity Hurricane Zone jurisdictions, and your permit application must include the NOA or Florida Product Approval documentation for every window being installed. We provide the correct documentation per configuration and pull the permit as part of the job. Call (561) 831-7863 and we will walk you through exactly what your municipality requires.
Yes, these windows are fabricated to your opening dimensions, not stock sizes. That applies to both replacements and new construction. We can also split wide openings into mulled sections, add transoms above a single hung, or pair single hung windows with fixed picture windows to create larger glass walls while preserving operable ventilation. Custom configurations may affect the NOA documentation, which we will handle for you.
Maintenance is straightforward. Wash the glass and frame with mild soap and water, keep the sill track clear of sand and debris, and lubricate the balance system annually if you have an aluminum frame. In coastal Palm Beach, salt spray builds up faster than inland, so rinse exterior frames monthly during the dry season. Do not pressure-wash the frames, as high-pressure water can damage weatherstripping and force water behind the flange. If a sash starts operating roughly, call us before forcing it; a simple adjustment beats a replacement.
