Single Hung Windows

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

Single hung windows are one of the most common impact-rated replacement profiles we install in Miami homes. They pair a fixed upper sash with an operable lower sash, both built around laminated impact glass. That’s the window style you’ve seen in thousands of Florida houses, from Kendall ranch homes to Coral Gables Mediterranean builds. Winslow Windows & Doors supplies and installs single hung impact windows across PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, and we handle the full job from measurement to final inspection.

Product Overview - Single Hung Windows

A fixed upper sash and an operable lower sash in laminated impact glass. That simple configuration is one of the most common impact-rated replacement profiles in Florida homes, and for good reason. It keeps sightlines clean, costs less than casement or horizontal roller profiles in most cases, and meets Miami-Dade’s strictest windborne debris standards when built correctly.

In Miami, a single hung window does more than ventilate. It’s a structural component of the building envelope. The upper sash never moves, which means fewer moving parts and fewer places for water to intrude under wind-driven rain. The lower sash tilts in for cleaning and closes against a reinforced frame. For bedrooms, living rooms, and kitchens where you want simple operation and a traditional look, single hung windows are the workhorse choice.

What separates a good single hung from a marginal one is the frame extrusion, the interlayer in the glass, and the way it’s set into the opening. We order these windows per project with design pressures matched to your wind zone, then install them so the NOA-rated assembly actually performs the way it was tested.

Technical Specifications

• Frame materials: Aluminum or vinyl, selected by opening size, structural load, and your budget.
• Glass options: Laminated impact glass with PVB interlayer, Low-E insulated glass, tinted glass, and clear glass.
• Finish options: White, almond, bronze, black, and tan.
• Screen options: Half screen and full screen.
• Design pressure: Matched to your wind zone, up to +/-100 PSF. Never higher.
• Compliance: Miami-Dade NOA and Florida Product Approval numbers available per configuration.
• Testing context: TAS 201, TAS 202, and TAS 203 protocol family for HVHZ-rated products.

We size each window to the rough opening rather than forcing a standard dimension into a nonstandard hole. In older Miami homes, which rarely have perfectly square openings, that matters more than most people realize.

Hurricane & Compliance Performance

Laminated Impact Glass
The glass unit includes a polyvinyl butyral (PVB) interlayer sandwiched between panes. When a storm throws debris at the window, the glass may crack, but the interlayer holds the pane together in the frame. That prevents wind and water from entering the house through a shattered opening, which is the failure mode that causes roofs to lift and walls to blow out.

Miami-Dade NOA / Florida Product Approval
Each configuration carries its own Miami-Dade Notice of Acceptance or Florida Product Approval number. These are not blanket certifications. The number applies to the specific frame, glass make-up, size range, and installation method on your quote. We verify the approval number before we order, and we give you a copy for your permit package.

FBC / HVHZ Compliance
These windows are engineered to Florida Building Code High-Velocity Hurricane Zone requirements. HVHZ is the strictest windborne debris region in the state, covering all of Miami-Dade and Broward. If your home is in Miami, your windows must meet this standard whether you’re replacing one opening or every opening on the house.

TAS 201 / 202 / 203 Testing Context
The testing protocol family gives you a sense of what these assemblies go through before they earn an approval. TAS 201 fires a large missile at the glass. TAS 202 cycles wind pressure against the assembly thousands of times. TAS 203 tests forced-entry resistance. Products that pass this sequence hold up under conditions far beyond a typical summer storm.

Design Pressure for Your Wind Zone
Design pressures are matched to your wind zone, up to +/-100 PSF. We order to your specific wind zone calculation, not a generic Miami number. A house in Surfside faces a different wind load than a house in inland Kendall, and over-specifying costs money while under-specifying fails inspection.

Energy Performance
Low-E and insulated glass options are available for energy performance. In Miami, summer heat gain through glass drives cooling costs more than winter heat loss. Low-E coatings reflect solar heat while letting visible light through. Tinted glass reduces glare and heat gain further. We’ll help you choose based on window orientation and how much shade your home gets.

Color & Glass Options

Five frame finishes cover most of what we see in Miami: white, almond, bronze, black, and tan. White and almond stay classic on older Florida ranch and mid-century homes. Black frames read modern and are increasingly common in newer architecture from Wynwood to Edgewater. Bronze suits Mediterranean and Spanish-influenced facades in Coral Gables and Pinecrest. Tan blends well on stucco homes with earthy exterior palettes.

On the glass side, clear laminated impact glass preserves the truest view and color. Tinted glass cuts glare in east and west-facing rooms that catch the hard Miami sun. Low-E insulated glass adds a thermal barrier, which helps on south-facing elevations. And you can combine Low-E with tint if heat gain is a serious issue. Each glass option changes the quote, so we spec it per room rather than defaulting to one option everywhere.

Installation by Winslow Windows & Doors in Miami

An impact window is only as good as the installation. That line shows up in every failure analysis we’ve reviewed over the years. The NOA number applies to the assembly installed under specific conditions, and sloppy perimeter sealing, shimming, or anchoring voids the tested performance. That’s why we follow a consistent process on every opening.

We start with a pre-install inspection of the rough opening, checking for rotted buck framing, out-of-square corners, and existing water damage around the jamb. In Miami’s coastal exposure zones, we also check for corrosion on existing anchor points from the old window. The new frame gets set level, plumb, and square. We shim deliberately, not by eye, and anchor per the product approval.

The perimeter gets sealed with AAMA 812-compliant low-expansion foam, followed by exterior sealant and trim work. Our installation practice follows AAMA 2400/2410 standards. After the window is set, we water-test the opening and check operation. Then we walk you through cleaning, screen installation, and operation before we leave.

Permitting is part of the conversation in Miami. HVHZ jurisdictions review window submittals against the NOA or Florida Product Approval. We provide the approval documents your permit requires and coordinate with your contractor or plan reviewer. If the inspector flags an issue, we’re still in the city and can address it.
