Double Hung Windows

Double Hung Windows in West Palm Beach, FL | Winslow Windows & Doors

Double hung windows are the classic Florida profile: two vertical sashes that glide up and down independently, with tilt-in cleaning access on both the top and bottom. In West Palm Beach, homeowners choose them because the look works on everything from a 1950s ranch in Southland Park to a new coastal contemporary in El Cid, and because impact-rated versions mean you aren’t trading that traditional appearance for storm protection. Winslow Windows & Doors supplies and installs impact double hungs across PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass configurations, all matched to your wind zone. We install in Palm Beach County every week, and every job is leveled, plumbed, and square before we call it done. Call (561) 660-9539 to talk through your opening sizes and get a line-item quote.

Product Overview - Double Hung Windows

A double hung window is two sashes in one frame, counterbalanced so each one slides vertically and stays where you put it. Both sashes tilt inward, which means you can clean both sides of the glass from inside your West Palm Beach home, no ladder and no screen removal. That matters more than people expect on second-story openings and anywhere with salt buildup from ocean air. The product’s profile is vertical and balanced, visually narrower than a horizontal slider, which is why you see it in older Florida homes and in newer construction that wants a traditional elevation.

What makes this version unusual is that it’s an impact window, not a standard window with shutters hung over it. The laminated impact glass does the protecting. The frame is available in aluminum or vinyl, and the hardware and balance system are built to carry the extra weight of laminated glass without sagging, which is the first thing that fails on a cheap retrofit. For a house in West Palm Beach, where a window might face the Atlantic wind-driven rain on one side and full afternoon heat on the other, the double hung’s combination of architectural fit and tested impact performance is the reason it stays one of our most quoted products in the impact series.

Technical Specifications

Here are the configurations Winslow Windows & Doors orders and installs for double hung windows in West Palm Beach and surrounding Palm Beach County. Every spec below comes from the manufacturer line you select; we help you match the right one to your opening and wind zone.

• Frame materials: Aluminum or vinyl. Aluminum for strength on large openings and coastal exposure; vinyl for thermal performance and a softer look in older neighborhoods.
• Glass options: Laminated impact glass with PVB interlayer, Low-E insulated glass, tinted glass, or clear glass. Glass packages are selected per opening and exposure.
• Color and finish options: White, almond, bronze, black, and tan. Finishes are applied at the factory, not in the field.
• Screen options: Half screen or full screen, depending on how you use the window and which sash you typically ventilate.
• Operation: Both sashes tilt in for cleaning; each sash operates independently.
• Hardware: Balanced for laminated glass weight. Locks and latches included per configuration.
• Sizing: Custom ordered to your opening dimensions. No stock sizes cut down on site.

Hurricane & Compliance Performance

Impact windows in Florida are tested, not assumed. Every configuration we order for West Palm Beach homes carries documentation that the local building department will actually accept. If you’ve ever had a permit kicked back, you know the difference between marketing language and an approval number. Here’s what sits behind these double hungs.

Laminated Impact Glass
The glass is two layers with a polyvinyl butyral (PVB) interlayer bonded between them. When impact hits, the glass may crack but the PVB holds the broken pieces in the frame, keeping the envelope of the house intact. The window remains in place after impact, which is the point of an impact-rated product rather than a standard insulated unit.

Miami-Dade NOA / Florida Product Approval
Double hung configurations carry Miami-Dade Notice of Acceptance and Florida Product Approval numbers. These are issued per configuration, meaning the specific glass, frame, and size combination on your window. We list the correct approval numbers on your quote so your permit submittal matches exactly. Verify on your specific quote, because an approval is tied to a configuration, not a product family in general.

FBC / HVHZ Compliance
The product is engineered to Florida Building Code High-Velocity Hurricane Zone requirements. West Palm Beach sits in a HVHZ jurisdiction, so this is not optional paperwork here. It’s the baseline for what a building department will accept, and we order and install to that standard on every impact window job in the city.

TAS 201 / TAS 202 / TAS 203 Testing Context
These are the Florida test protocols behind the rating. TAS 201 covers large-missile impact, TAS 202 covers cyclic wind-pressure loading, and TAS 203 covers forced-entry resistance. Together they make up the protocol family HVHZ-rated products are tested under. We mention them because they’re what your plans examiner will look for.

Design Pressure for Your Wind Zone
Design pressures are matched to your wind zone, up to +/-100, never higher. What that means in practice: we don’t sell you a DP number you don’t need, and we don’t under-spec an opening just to save a dollar. The rating follows the elevation, exposure, and location of the opening on your West Palm Beach home.

Energy Performance
Low-E and insulated glass options are available on double hungs, which matters in West Palm Beach summers when the west-facing glass turns a room into an oven by 4 p.m. We can customize the glass package by elevation, so south and west openings get a different spec than shaded north openings.

Color & Glass Options

Color on a window does two jobs in West Palm Beach: it has to hold up to sun and salt, and it has to sit right against the house. White is the most common finish and what you’ll see on most newer stucco construction here. Almond and tan read warmer, which is why they work on Mediterranean-style homes in neighborhoods like Flamingo Park and Sunshine Park, where the trim and roof tiles lean terracotta. Bronze and black have become the go-to on modern and coastal contemporary elevations, especially paired with white stucco or concrete block. The finish is factory-applied, so it won’t peel the way a field-painted frame will after a few hurricane seasons.

Glass selection is a sun-exposure question, not a style question. Clear laminated impact glass is the honest workhorse: impact protection, natural light, no tint. Tinted glass cuts glare and heat on east and west elevations, and it happens to pair well with black and bronze frames. Low-E insulated glass is the choice when you’re replacing windows in rooms you actually live in during the afternoon, because it blocks a meaningful amount of solar heat while the window is closed. Most West Palm Beach homes end up with mixed glass packages by elevation, which is exactly how we quote them.

Installation by Winslow Windows & Doors in West Palm Beach

An impact window with a perfect NOA is only as good as the hole it sits in. We’ve pulled failed retrofits out of West Palm Beach homes where the window itself was fine, but the perimeter was never sealed correctly, so the first real storm drove water behind the frame. That’s why our install process is built around the product’s rating staying intact after it leaves the factory.

Every replacement starts with a pre-install inspection of the rough opening. In older Palm Beach County homes, that often means finding rot, settling, or framing that’s out of square before the new window ever arrives. We measure and order to the opening as it exists, not as the original plans say it should be. During install, the frame is set level, plumb, and square, shimmed where needed, and fastened per the manufacturer’s approved installation method. We use AAMA 812 low-expansion foam around the perimeter for an air and water seal, and our practice follows AAMA 2400/2410 standards for installation workmanship. After the window is in, we run a water test on the opening and walk you through operation and tilt-in cleaning before cleanup starts.

Permitting matters in West Palm Beach because the city sits in an HVHZ jurisdiction. Plans reviewers here expect the Florida Product Approval or Miami-Dade NOA numbers on the submittal to match the exact windows going into the openings. We handle that documentation on the jobs we install. If you hire a handyman and buy the windows yourself, you own that process alone, and a missing approval number is the easiest way to stall a permit for weeks. With us, the quote, the submittal, and the install reference the same configuration sheet.

Frequently Asked Questions - Double Hung Windows

What wind zone / design pressure is the Double Hung Windows rated for?
Design pressures are matched to the wind zone of your specific opening in West Palm Beach, up to +/-100. We never specify higher than the opening requires and never lower than the building department will accept. Call (561) 660-9539 and we’ll check the DP rating for your elevation and opening size before you commit to anything.

What is the lead time?
Lead times run on the manufacturer’s production schedule for your chosen line, and they move. PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass all run different queues. Ask us for the current lead time on the specific configuration we quote, and we’ll give you the realistic number, not the optimistic one. Call (561) 660-9539 and we’ll check current production windows on the line you’re considering.

Does it require a Miami-Dade NOA or Florida Product Approval submittal for my permit?
Yes. In West Palm Beach and anywhere else in an HVHZ jurisdiction, the building department expects the approval number on your permit submittal to match the exact configuration installed. We provide the correct NOA or Florida Product Approval numbers on our quote so the submittal goes through without a correction cycle. Call (561) 660-9539 and we’ll walk you through what your specific opening requires.

Can I customize the size or configuration?
Yes. These are ordered per opening, so custom widths and heights are standard practice, not an upcharge. Sash configuration, glass package, frame material, color, and screen type are all selected per opening. If you have an odd-size opening in an older West Palm Beach home, that’s normal for us. Call (561) 660-9539 with your rough opening dimensions and we’ll quote what fits.

How do I maintain the frame?
Rinse the frame and tracks every couple of months, more often if you’re close to salt air off the Intracoastal. Keep the track clear of sand and debris, and wipe the weatherstripping with a damp cloth rather than a solvent. The tilt-in sashes make glass cleaning simple from inside, which is the whole point of the design.
