AfterDouble Hung Windows in Palm Beach, FL | Winslow Windows & Doors
Double hung windows are the classic American window: two sashes stacked vertically, both of which glide up and down for ventilation from the top or bottom. In Palm Beach, FL, the version you want is different from what you’d install in Ohio. Ours are built around laminated impact glass and rigid aluminum or vinyl frames engineered for the Florida Building Code’s High-Velocity Hurricane Zone requirements. Winslow Windows & Doors supplies and installs impact-rated double hung windows across Palm Beach, West Palm Beach, Lake Worth, and the surrounding coastal communities. We handle the measuring, permitting support, and installation so the system performs the way its Miami-Dade NOA was issued to perform. Call (561) 782-7525 for a free on-site estimate.
Product Overview - Double Hung Windows
A double hung window gives you two operable sashes: the bottom one lifts, and the top one pulls down. Both tilt inward for easy cleaning from inside your home, which is a real benefit on second-story openings in Palm Beach homes where exterior access isn’t convenient. The traditional profile suits nearly every architectural style found in Palm Beach County, from 1920s Mediterranean Revival cottages to mid-century ranches and newer coastal contemporary builds.
What makes the impact version of this product different is the glazing and the engineering behind it. The laminated impact glass uses a PVB (polyvinyl butyral) interlayer that holds the glass in the frame if a storm-borne object hits it. The frame itself, whether aluminum or vinyl, is reinforced and tested as a complete assembly, not just as a pane of glass. That assembly-level testing is what matters for hurricane protection. A window is only as strong as its weakest connection, which is why the frame, glass, and hardware are tested together under the TAS protocol family. For Palm Beach homeowners, this is the difference between a window that looks impact-rated and one that actually is.
We supply double hung windows through our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, so you can choose the frame platform, finish, and glass package that fits your home and budget.
Technical Specifications
Here’s the double hung window built out the way we order it for Palm Beach projects. Exact dimensions are confirmed during the free on-site measurement, but the specification ranges below give you a working framework.
- Frame materials: Aluminum or Vinyl. Aluminum offers a slimmer sightline and is common on larger openings; vinyl brings thermal performance and a lower-maintenance profile.
- Glass options: Laminated impact glass (PVB interlayer), Low-E insulated glass, tinted glass, and clear glass. You can combine laminated impact glass with a Low-E coating and insulated airspace for hurricane protection plus energy performance.
- Finish options: White, Almond, Bronze, Black, and Tan. These are powder-coated or factory-finished depending on the line.
- Screen options: Half screen or full screen. Half screens cover the bottom sash opening; full screens cover the entire window for ventilation with both sashes open.
- Operation: Vertical glide on both sashes with tilt-in cleaning on top and bottom.
- Design pressure: Matched to your specific Palm Beach wind zone, up to +/-100. We never spec higher than your zone requires, because that only adds cost without adding useful protection.
Hurricane & Compliance Performance
Our double hung windows use laminated glass with a PVB interlayer. If a wind-borne object strikes the glass, the interlayer holds the pane in the frame rather than letting it shatter inward. That’s the core of the protection, and it’s standard on every impact double hung we quote in Palm Beach.
Each configuration carries a Miami-Dade Notice of Acceptance and/or Florida Product Approval number. These are issued per configuration, so the exact model, size, and glass package on your quote has its own approval number you can verify. We provide the documentation when you pull your permit.
The window is engineered to Florida Building Code High-Velocity Hurricane Zone requirements. HVHZ is the stricter Florida code tier that applies to Palm Beach County and Miami-Dade, and it governs everything from glass retention to frame anchoring.
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 are the tests the window assembly passes so you know it’s not a fair-weather window.
Design pressure is matched to your wind zone, up to +/-100. A home on the Intracoastal in West Palm Beach faces different loading than one further inland, and we order the right rating for the actual site, not a one-size-fits-all number.
Low-E and insulated glass options are available for energy performance. If you’re replacing old single-pane windows in Palm Beach, adding a Low-E insulated glass package is one of the most practical upgrades you can make without changing the window’s classic look.
Color & Glass Options
Palm Beach architecture leans heavy on white, coastal neutrals, and dark bronze accents. White remains the most popular finish for double hung windows here because it suits the bright Florida light and pairs naturally with both stucco and wood siding. Almond and Tan work well on warmer Mediterranean and Spanish-style homes where bright white reads too stark. Bronze and Black add contrast and are increasingly common on contemporary coastal builds and homes with black hardware or lighting.
On the glass side, clear laminated impact glass is the straightforward choice: full protection with no tint changing your view. Tinted glass reduces glare, which matters a lot when your windows face east or west and catch the Palm Beach sun hard in the morning or late afternoon. Low-E insulated glass improves energy performance by reflecting heat while still letting light through. If you want the best of both worlds, we order laminated impact glass with a Low-E coating and an insulated airspace. Ask about the combination when you call (561) 782-7525.
Installation by Winslow Windows & Doors in Palm Beach
An impact window is a system, and the installation is part of that system. A correctly rated window installed incorrectly won’t perform to its NOA, and it won’t pass a Palm Beach County inspection. That’s why our installation work follows AAMA 2400/2410 practice, which covers the full install sequence: proper opening preparation, correct anchoring, and perimeter sealing. We also use AAMA 812 low-expansion foam perimeter sealant, which seals the gap between the frame and the rough opening without warping the frame as it cures.
Our process starts with a pre-install inspection and full measurement of every opening. We check the condition of the rough opening, look for prior water damage, and confirm the stud cavity so the anchors bite into structure, not trim. Then we set each window level, plumb, and square. That’s not installer jargon; it’s the difference between sashes that glide and sashes that bind. In coastal Palm Beach, where a few millimeters of rack can cause a lifetime of frustration, we take the time to get it right.
Palm Beach-specific conditions matter. Salt air accelerates corrosion on hardware and fasteners, so we use corrosion-resistant anchors rated for the exposure. Wind zones vary by exact address, so we verify the design pressure before ordering. And permitting in HVHZ jurisdictions requires NOA and Florida Product Approval documentation on file, which we provide with your submittal package. When the install is done, we run a water test on the perimeter, clean up the site, and walk you through operation and maintenance.
Improper installation compromises the NOA-rated system. No window can fix a bad opening or a poorly sealed perimeter. If you’re investing in impact double hung windows in Palm Beach, the install is not the place to cut corners.
Frequently Asked Questions - Double Hung Windows
Design pressure is matched to your specific Palm Beach wind zone, up to +/-100. We don’t order a higher rating than your site requires because it adds cost without adding protection. During your free on-site measurement, we confirm the exact DP rating for your address. Call (561) 782-7525 to schedule that measurement.
Lead times depend on the manufacturer line, frame material, and glass package. PGT and CGI lines typically run shorter lead times than custom ES Windows or ECO configurations, but current schedules fluctuate. We give you a written lead time with your quote, and we update it before you sign. Call (561) 782-7525 and ask for a current lead time for your specific configuration.
Yes, in HVHZ jurisdictions like Palm Beach County, your permit package needs the NOA and/or Florida Product Approval numbers for the specific window configurations you’re installing. Verifying these numbers on your quote is standard practice, and we provide the approval documentation with your submittal. If you’re checking numbers on your own, the exact model, size, and glass package must match the approval. We can walk you through it when you call (561) 782-7525.
Yes, double hung windows are ordered to the exact opening dimensions we measure on site. Standard sizes exist, but the window is not a stock off-the-shelf item for most Palm Beach homes. You can also customize the finish color, glass package, and screen type (half or full). We’ll spec the configuration that matches your existing architecture. Call (561) 782-7525 for a free on-site measurement and quote.
Keep the tracks clean and free of sand and debris, which is a constant in Palm Beach. Wipe down the frames with mild soap and water a few times a year, and avoid abrasive cleaners on the finish. The tilt-in sashes let you clean both glass surfaces from inside your home. For hardware lubrication, use a dry silicone spray, not oil-based products that attract grit.
