Double Hung Windows

Double Hung Windows in Miami Beach, FL | Winslow Windows & Doors

Double hung windows are the classic vertical-glide profile Miami Beach homeowners ask for when they want a traditional look that still meets Florida’s hurricane codes. Both sashes move independently and tilt inward for easy cleaning, while the laminated impact glass does the heavy lifting during a storm. Winslow Windows & Doors installs these across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, so you get the right configuration for your building rather than whatever a supplier happens to have in stock. We’re based in Florida, we install in Miami Beach, and we know what a HVHZ inspection actually looks for. Call (863) 656-0462 to talk through your project.

Product Overview - Double Hung Windows

Double hung windows have two operable sashes, top and bottom, sliding vertically within the same frame. That’s the design you see on older Florida cottages, mid-century apartment buildings, and a lot of Miami Beach condos where the architecture leans traditional. The difference with an impact-rated version is what you can’t see: the laminated glass that holds together when debris hits it, and the frame engineering that keeps the whole assembly secured to the wall during cyclic wind loading.

What makes this profile work in Miami Beach is the combination of form and function. You keep the look of a classic window, but you’re not sacrificing the protection your building code demands. Both sashes tilt in, which matters more than people realize in a coastal environment. Salt air and sand build up on exterior glass; being able to clean both sashes from inside the unit is a real benefit in a high-rise or a two-story home where you don’t want to be on a ladder every month.

The frames come in aluminum or vinyl. Aluminum gives you the slimmer sightlines that architects prefer on modern and mid-century buildings. Vinyl offers thermal performance advantages and a lower maintenance profile for single-family homes. Both are engineered to accept laminated impact glass, and both are available through Winslow Windows & Doors with full Miami-Dade compliance documentation.

When we install double hung windows in Miami Beach, we’re typically replacing older single-pane units that predate current code. That’s a significant upgrade: laminated glass, better seals, tighter tolerances, and hardware that actually functions after years of salt exposure. Call (863) 656-0462 if you’re starting to research replacement options.

Technical Specifications

Here’s what’s available on the Double Hung Windows Impact Series through Winslow Windows & Doors. Every configuration changes the specification, so use this as a reference point and we’ll confirm exact numbers on your written quote.

• Frame materials: Aluminum or vinyl, selected for the exposure and aesthetic of your specific building
• Glass options: Laminated impact glass with PVB interlayer, Low-E insulated glass, tinted glass, or clear glass
• Finish options: White, almond, bronze, black, and tan
• Screen options: Half screen or full screen
• Operation: Both sashes slide vertically and tilt inward for cleaning
• Design pressure: Matched to your wind zone, up to +/-100, never higher
• Compliance: Miami-Dade NOA and Florida Product Approval numbers available per configuration
• Code compliance: Engineered to Florida Building Code High-Velocity Hurricane Zone requirements

Size range depends on the frame material and the design pressure your building needs. A window that works on a third-floor condo in South Beach may not carry the same NOA at a ground-floor single-family home further west. We verify every configuration before we quote it. No guesswork.

Hurricane & Compliance Performance

Laminated Impact Glass - The glass uses a PVB (polyvinyl butyral) interlayer sandwiched between two panes. When impact occurs, the interlayer holds the glass in the frame rather than letting it shatter inward. That’s the core of what makes an impact window different from standard glass, and it’s what your Miami Beach building department expects to see on the product approval paperwork.

Miami-Dade NOA / Florida Product Approval - Every configuration we quote carries the appropriate Miami-Dade Notice of Acceptance or Florida Product Approval number. These numbers are issued per configuration, meaning the specific size, frame, and glass combination you buy is the exact one that was tested. We provide the compliance documentation for your permit submittal.

FBC / HVHZ Compliance - Double hung impact windows from Winslow Windows & Doors are engineered to Florida Building Code High-Velocity Hurricane Zone requirements. Miami Beach sits squarely in the HVHZ, which is the strictest wind-borne debris region in the state. This isn’t optional compliance; it’s the law for any permitted replacement window in this jurisdiction.

TAS 201 / 202 / 203 Testing Context - HVHZ-rated products are tested under the TAS protocol family. TAS 201 covers large-missile impact, TAS 202 covers cyclic wind-pressure loading, and TAS 203 covers forced-entry resistance. When a product says it’s Miami-Dade approved, these are the tests behind that claim.

Design Pressure for Your Wind Zone - Design pressure is a PSF rating that describes how much wind load the window can withstand without failing. We match design pressure to your specific wind zone and building height, up to +/-100. We never spec a higher DP than what your building actually needs, because over-engineering adds cost without adding protection.

Energy Performance Options - Low-E insulated glass and tinted glass are available for buyers who want the impact protection plus better energy performance. Low-E coatings reduce solar heat gain, which matters when your windows face the afternoon Miami Beach sun. Tinted glass does similar work while changing the exterior appearance. Clear glass remains the traditional look many condo associations require.

Color & Glass Options

The five finish options, white, almond, bronze, black, and tan, give you real flexibility across Miami Beach’s architectural range. White works on classic mid-century condos and the older Art Deco buildings where a crisp frame line is part of the look. Almond and tan blend into the stucco tones you see on Mediterranean-revival homes in the Flamingo Park area and throughout mid-beach. Bronze and black are the choice on modern builds in South of Fifth and new construction on the west side, where darker frames create stronger contrast against glass.

On glass, the choice usually comes down to how much sun exposure the opening gets. Clear laminated impact glass preserves the view and keeps the exterior appearance unchanged, which matters on buildings with a consistent facade. Low-E insulated glass is the pick for east and west facing windows that take direct sun, reducing heat gain and protecting interior furnishings. Tinted glass works well on upper floors where glare is constant but you don’t want to sacrifice the view entirely. Your quote will list the exact glass configuration we’re proposing, with the NOA number tied to it.

Installation by Winslow Windows & Doors in Miami Beach

An impact window is only as good as its installation. That’s not a sales line; it’s a code reality. A window with a valid Miami-Dade NOA becomes a liability if it’s installed with the wrong fasteners, the wrong sealant, or a frame that isn’t level and square. The product approval assumes proper anchoring per the tested installation method. If the installation deviates, the rating means nothing.

That’s why our Miami Beach installation process starts with a pre-install inspection of the opening. We check the existing buck, the condition of the surrounding substrate, and we verify that the window we’re installing matches the configuration on the NOA we submitted for permit. We don’t swap products mid-job. We set every unit level, plumb, and square before anchoring, following AAMA 2400/2410 practice for installation.

Perimeter sealing uses AAMA 812 low-expansion foam with the appropriate backer rod and exterior sealant system. This prevents air and water intrusion without putting pressure on the frame that could distort the sash operation. After installation, we run a water test on the perimeter and confirm both sashes operate cleanly, tilt properly, and lock securely.

Miami Beach has specific permitting requirements for window replacement in the HVHZ. Any window you install here needs a permit, and that permit needs product approval documentation. We handle that paperwork as part of the job, because we’ve done it hundreds of times in this jurisdiction. Coastal exposure, wind zone calculations, and condo association requirements all factor into what we quote. Call (863) 656-0462 if you want an installer who already knows what Miami Beach requires.
