Double Hung Windows

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

Double hung windows are the classic vertical-slide profile Miami homeowners know from older Florida architecture, rebuilt here for hurricane-country performance. Both sashes glide up and down, and both tilt inward for cleaning, which matters when your windows face salt air and seasonal storm debris. Winslow Windows & Doors supplies and installs impact-rated double hung windows across PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, configured for Miami-Dade HVHZ compliance. We install them level, plumb, and square throughout Miami, from Coconut Grove to Kendall to Pinecrest. Call (863) 946-5039 to discuss your project.

Product Overview - Double Hung Windows

A double hung window is the traditional profile people picture when they think of a Florida home: two sashes stacked vertically, each sliding in its own track. Both the top and bottom sash tilt inward on this impact series, so cleaning a second-story window from inside the house is a five-minute job, not a ladder-and-pray situation. That tilt-in function also makes routine hardware checks easier over the life of the window.

What separates these from a standard double hung is the glass package. Every configuration we sell for Miami installations carries laminated impact glass with a PVB interlayer, the same technology behind hurricane-rated storefronts and commercial glazing throughout South Florida. The glass is engineered to stay in the frame if a storm throws debris at it, protecting both the building envelope and the people inside.

Architecturally, double hungs fit the older Miami housing stock, think Coral Gables Mediterranean revival, Morningside bungalows, Shenandoah frame homes, better than almost any other operable window. They also hold their own in new construction where the design calls for a traditional look. We offer them in aluminum and vinyl, materials chosen for corrosion resistance in coastal air and long-term dimensional stability through Miami’s wet-dry cycles and UV exposure.

For Miami homeowners replacing original wood or single-pane aluminum windows, this product is often the most natural visual match. For homeowners building new, it gives you the old-Florida look with new-Florida impact protection. Call (863) 946-5039 to talk through which frame material and glass package fits your home.

Technical Specifications

Here is what you select from when we configure your double hung impact windows for a Miami installation:

Frame Materials

• Aluminum: A narrower frame profile than vinyl, which means more glass area and a sleeker sightline. Aluminum handles Miami’s sun and salt exposure well when properly finished, and it is the material most often specified for coastal condominium and high-rise work.
• Vinyl: A thermally efficient frame with fewer internal components, which translates to a tight, quiet operation. Vinyl is a strong choice for single-family homes, rentals, and any project where you want impact performance without metal frames conducting heat.

Glass Packages

• Laminated Impact Glass (PVB interlayer): The core impact package required in HVHZ zones. The PVB interlayer is what keeps the glass bound together under debris impact.
• Low-E Insulated Glass: Adds a second pane with a low-emissivity coating, improving thermal performance for homes that fight afternoon sun in neighborhoods like Westchester or Kendall.
• Tinted Glass: Reduces glare and solar heat gain, a sensible choice for west-facing rooms across Miami.
• Clear Glass: Maximum visible light transmission for shaded lots, north elevations, or owners who want the truest color view.

Finish Options

• White
• Almond
• Bronze
• Black
• Tan

Screen Options

• Half Screen: Covers the lower sash opening, which is how most Miami homeowners run their double hungs day to day.
• Full Screen: Covers the full opening when both sashes are open, useful for cross-ventilation in spring and fall.

Hurricane & Compliance Performance

Here is what these windows are engineered to do, and the compliance documentation that backs your Miami permit:

Laminated Impact Glass

The glass in these double hungs uses a polyvinyl butyral interlayer sandwiched between glass lites. Under impact, the lites may crack, but the interlayer holds the broken pieces in the frame instead of letting wind, rain, and flying debris into your living room. That is the single most important storm-protection property of this product.

Miami-Dade NOA / Florida Product Approval

Each configuration carries Miami-Dade Notice of Acceptance and Florida Product Approval documentation. Because approvals are issued per configuration, meaning specific frame size, glass package, and design pressure, we verify the relevant numbers on your written quote before you submit for permit. You will have the paperwork your AHJ asks for.

FBC / HVHZ Compliance

These windows are engineered to Florida Building Code High-Velocity Hurricane Zone requirements. That is the stricter of Florida’s two wind-region codes, and it governs Miami, Miami Beach, Coral Gables, and every other municipality in Miami-Dade County.

TAS 201 / TAS 202 / TAS 203 Testing Context

The protocol family these products are tested under includes TAS 201 for large-missile impact, TAS 202 for cyclic wind-pressure loading, and TAS 203 for forced-entry resistance. Together they simulate the repeated loading and debris impact a Miami window actually faces during a hurricane, not just a one-time strike.

Design Pressure for Your Wind Zone

We specify the design pressure rating to your exact wind zone, up to +/-100, and never higher than the location actually requires. Over-specifying adds cost without adding safety. Under-specifying fails your permitting review. Your quote lists the precise PSF rating for your address in Miami.

Energy Performance Options

Low-E insulated glass is available on these double hungs for homes where air conditioning costs are a concern, which in Miami is nearly every home. The insulated unit cuts heat transfer through the glass, and the Low-E coating reflects solar energy while still letting in light.

Color & Glass Options

The finish options for these double hung windows cover the range of Miami residential architecture without stretching into anything that looks out of place. White and Almond read clean against cream stucco and Spanish-style homes in neighborhoods like Coral Way and Shenandoah. Bronze and Black give you the darker frame look popular on modern builds in Edgewater and the Design District, and they hide salt-dust film better between cleanings. Tan suits ranch-era houses and duplexes where a mid-tone frame blends with beige and sand finishes.

On the glass side, the choice comes down to how your specific elevation handles sun. West-facing rooms in Westchester or Doral get hammered by late afternoon sun, so tinted or Low-E insulated glass is usually the better call. North-facing windows on a shaded Coconut Grove lot can take clear glass and still perform. The laminated impact layer is present in every package regardless, so the non-impact glass choices are about comfort and energy, not storm safety. We will help you pick per elevation, not per house, because Miami sun exposure changes dramatically from the front wall to the back wall.

Installation by Winslow Windows & Doors in Miami

An impact window is only as good as the opening it sits in. The NOA and Florida Product Approval ratings assume the product is installed as engineered. If the frame is racked, the shim pattern is wrong, or the perimeter seal is not continuous, the window loses capacity in ways no document on file will reveal until a storm finds it. That is why we control the full installation, not just the sale.

Our process starts with a pre-install inspection of the rough opening: condition of the buck, any hidden rot or corroded anchors, and the actual dimensions versus what was ordered. We then set each window level, plumb, and square, shim at the correct anchor points, and fasten per the approved installation method for that frame material and substrate.

The perimeter gets an AAMA 812 low-expansion foam sealant, which fills voids without pushing the frame out of true, followed by the exterior trim and flashing detail appropriate for the wall assembly. This work follows AAMA 2400 and 2410 standard practice for window installation. In Miami, that means accounting for the high-wind suction loads on the leeward side of the building during a storm, which is where bad flashing jobs leak first.

After installation, we run a final water test on the opening and walk the line with you before we call the job complete. We are familiar with HVHZ permit requirements in Miami-Dade and the documentation your local building department will ask for, from product approval submittals to the sticker on the frame itself. Permitting is part of the project; we make sure the paperwork matches the product that was actually installed. Coastal exposure, wind zone, and elevation require attention to detail that a generic installer will not catch. You are in Miami. Detail matters.
