Double Hung Windows

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

Double hung windows are the classic choice for Fort Lauderdale homes that need real hurricane protection without losing their traditional look. Both the top and bottom sashes operate vertically, and both tilt inward for cleaning, which means you get air flow, easy maintenance, and impact-rated glass in one window. At Winslow Windows & Doors, we install double hung windows across PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, and we set them to perform in the coastal wind conditions we deal with every day here. The profile reads as timeless; the engineering is anything but. Call (904) 913-5886 to talk through options.

Product Overview - Double Hung Windows

What makes this profile so well suited to hurricane-prone construction in Fort Lauderdale is the combination of the familiar and the fortified. The double hung style has been the default American window for over a century, and in many of the city’s older neighborhoods, from Victoria Park to Sailboat Bend, replacement windows need to respect that architectural vocabulary. This product does that. But instead of a single pane of annealed glass held in a wood sash, you get laminated impact glass with a PVB interlayer, set inside an aluminum or vinyl frame engineered to take a hit without coming apart.

The tilt-in sashes on both top and bottom are the practical feature most people appreciate after living with the window for a year. You clean both sides of the exterior glass from inside the house, which matters on second-story installations where no one wants to drag out a ladder in June. The vertical glide action is smooth and the balance system is built for thousands of cycles. We install these in Fort Lauderdale homes with the same care we give our heavier horizontal roller products, because when a window fails in a hurricane, it’s rarely the glass. It’s the install.

The laminated glass is the same category of protection specified in Miami-Dade HVHZ applications, meaning the glass is designed to stay in the frame under impact, not shatter into a thousand shards. That’s the difference between a window that leaks after a storm and a window that keeps the envelope sealed. Call (904) 913-5886 to discuss which configuration fits your openings.

Technical Specifications

You choose the frame material, glass package, finish, and screen configuration to match your home. Here’s what’s available on this product through Winslow Windows & Doors:

• Frame materials: Aluminum or vinyl. Aluminum is the go-to for coastal Fort Lauderdale salt exposure and provides tighter sightlines on larger openings. Vinyl offers stronger thermal performance and a lower maintenance profile for inland neighborhoods like Plantation or Davie where you’re still in the same wind zone but not directly on the ocean.
• Glass options: Laminated impact glass with a PVB interlayer as the structural foundation. From there you can add Low-E coatings, insulated glass units for energy performance, tinted glass for glare and solar control, or clear glass for the brightest interior.
• Color and finish options: White, almond, bronze, black, and tan. Both the interior and exterior finish can be specified separately on most lines.
• Screen options: Half screen or full screen, depending on how you plan to use the window for ventilation.
• Design pressure: Matched to your wind zone, up to +/-100. We never push a higher DP rating than the opening actually requires, because over-specifying costs you money for nothing.

Lead times, exact frame dimensions, and configuration-specific NOA numbers get locked down on your written quote. What you see here is the menu. What we build for your house is a specific set of choices.

Hurricane & Compliance Performance

This is the section that matters most for a Fort Lauderdale replacement window. Every claim below reflects how this product is engineered and tested, and how Winslow Windows & Doors verifies it before we order and before we install.

Laminated Impact Glass
The glass package uses a PVB (polyvinyl butyral) interlayer laminated between panes. Under impact, the glass may crack but the interlayer keeps the broken pieces bonded in place so the window doesn’t open the building envelope to wind and water. That’s the mechanism that protects your house when debris hits the window.

Miami-Dade NOA and Florida Product Approval
This product meets Miami-Dade NOA (Notice of Acceptance) and Florida Product Approval requirements, with numbers issued per configuration. We verify the NOA and FL approval numbers on your specific quote before anything is ordered or permitted.

FBC High-Velocity Hurricane Zone Compliance
Engineered to Florida Building Code (FBC) High-Velocity Hurricane Zone (HVHZ) requirements, which govern Fort Lauderdale and the rest of Broward County’s coastal zone. This isn’t a marketing claim. It’s what building officials look for on a permit set.

TAS Testing Protocol Family
HVHZ-rated products in this category are tested under the TAS protocol family: TAS 201 for large-missile impact, TAS 202 for cyclic wind-pressure loading, and TAS 203 for forced-entry resistance. These tests simulate the repeated cycling of hurricane-force winds, not a single hit.

Design Pressure for Your Wind Zone
Design pressures are matched to your wind zone, up to +/-100, and never higher. We calculate the DP requirement for your specific elevation, exposure, and opening size, then spec the configuration that meets it precisely. That keeps you code-compliant without paying for a rating the opening doesn’t need.

Energy Performance Options
Low-E glass and insulated glass units are available on this product line. In Fort Lauderdale’s climate, Low-E coating on an impact-rated laminated glass unit cuts direct solar gain without compromising the protective interlayer. We help you weigh visible light transmission against heat rejection depending on which side of the house the window faces.

Color & Glass Options

The finish you choose does more than match trim. Bronze and black frames on a white Mediterranean-style house in Rio Vista read crisp and coastal. Almond and tan tones disappear into warm stucco palettes in Poinsettia Heights. White works on nearly any era of Florida architecture. All five finishes are durable, color-stable options across the product lines we install, so the exterior doesn’t fade under constant Fort Lauderdale sun.

Glass is a performance decision more than an aesthetic one. Clear laminated impact glass gives you the most natural light and the most traditional look, but it transmits the most heat. Tinted glass cuts glare and solar gain, which matters on west-facing walls where the afternoon sun is relentless. Low-E insulated glass is the strongest energy play and the one we recommend most often for Fort Lauderdale homes that face prolonged sun exposure. The impact layer is always there; the energy package is what you layer on top of it.

Installation by Winslow Windows & Doors in Fort Lauderdale

We treat installation as part of the system, because an NOA-rated window set carelessly is no longer an NOA-rated window. The approval documents assume proper anchoring, proper sealing, proper shimming. If the frame isn’t level, plumb, and square, the sashes bind, the weatherstripping doesn’t seat, and water finds a path in. You paid for the engineering. The install is what makes the engineering work.

Our process in Fort Lauderdale starts with a pre-install inspection of every opening. We check the rough opening dimensions against the window size, inspect for rot or termite damage around the frame, and verify the surrounding wall condition before we remove anything. If the opening is out of square, we correct it. If there’s water damage from an old window, we stop and tell you before we bury it behind a new frame.

Installation practice follows AAMA 2400/2410 standards. We set the window level, plumb, and square, anchor per the product’s approved anchoring schedule, and use AAMA 812 low-expansion foam as the perimeter sealant. The foam expands gently to fill the gap between the frame and the rough opening without bowing the jambs. We detail the exterior joint with the appropriate sealant for the product and finish it cleanly. After the window is in, we run a water test on the installation and walk you through operation and cleaning before we leave. The jobsite gets swept and old windows get hauled off. You shouldn’t know we were there except for the new windows.

Permit awareness matters in this market. Fort Lauderdale sits in a High-Velocity Hurricane Zone under the Florida Building Code, and most window replacement projects require a permit with product approval documentation submitted by the installer. We know what the city and Broward County plan reviewers look for. If your project needs it, we provide the configuration-specific NOA and Florida Product Approval information so you’re not waiting on paperwork at the counter.
