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 across Miami homes. The design is straightforward: a fixed upper sash and an operable lower sash, both glazed with laminated impact glass. They fit the architectural language of Florida ranches, 1950s concrete-block houses, and newer Mediterranean builds equally well. Winslow Windows & Doors supplies and installs these across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, so you’re not locked into one manufacturer’s sizing. Call (844) 901-4551 to talk through your opening sizes and wind zone.

Product Overview — Single Hung Windows

Single hung windows earned their place in South Florida construction for a reason: they do one thing well, and they do it without unnecessary moving parts. The upper sash stays fixed. The lower sash slides up to ventilate. That simple operation means fewer seals to maintain, fewer failure points, and a tighter frame-to-wall connection when installed correctly.

What makes this profile suited to hurricane-prone construction is the glass package. Both sashes carry laminated impact glass with a PVB interlayer. When debris strikes, the glass may crack, but the interlayer holds the fragments in place. The opening stays sealed. Wind-driven rain stays outside. That’s the entire point of an HVHZ-rated window: not indestructibility, but containment.

Architecturally, single hungs read as traditional and understated. They’re at home in Coral Gables colonials, Shenandoah bungalows, and the 1960s-era apartment conversions we see throughout Little Havana and Allapattah. The vertical proportions work well on smaller facades where a sliding window would feel visually wide. We regularly specify them for bedroom egress openings, living room picture walls, and side-yard elevations where a casement would swing into a walkway.

Frame material matters in Miami’s humidity and salt air. We offer aluminum frames for strength and narrow sightlines, and vinyl frames for thermal performance and a lower maintenance profile. Both are available with impact glazing and Miami-Dade NOA documentation. The choice usually comes down to building type, condo association requirements, and budget. Our team walks you through the trade-offs before you commit.

Technical Specifications

• Frame materials: Aluminum or Vinyl
• Glass options: Laminated Impact Glass with PVB interlayer, Low-E Insulated Glass, Tinted Glass, Clear Glass
• Finish options: White, Almond, Bronze, Black, Tan
• Screen options: Half Screen or Full Screen
• Design pressure: Matched to your wind zone, up to +/-100, never higher

• Operation: Fixed upper sash, operable lower sash

Sizing is configuration-dependent. We’ll confirm exact maximum widths and heights for your chosen frame material and design pressure rating during the estimate. What we won’t do is sell you a higher design pressure than your wind zone calls for. Paying for +/-100 when your elevation needs +/-60 is wasted money, and we’ll tell you that directly.

Hurricane & Compliance Performance

Laminated Impact Glass

The PVB interlayer is the heart of this window. Under large-missile impact, the glass fractures but the interlayer stretches and holds the fragments bonded to the frame. The opening remains a barrier against wind and water intrusion. This is the defining feature of any legitimate Miami impact window, and it’s standard here, not an upgrade.

Miami-Dade NOA / Florida Product Approval

Every configuration we sell carries a Miami-Dade Notice of Acceptance or Florida Product Approval number. These are issued per configuration, meaning the specific combination of frame, glass, size, and design pressure matters. We verify the exact NOA or FL approval number on your quote so your permit submittal is clean the first time.

FBC / HVHZ Compliance

Single hung windows in this series are engineered to Florida Building Code High-Velocity Hurricane Zone requirements. HVHZ is the strictest wind-borne debris region in the state, covering Miami-Dade and Broward. A window that passes elsewhere may not pass here. Ours are built for this code from the start.

TAS 201 / 202 / 203 Testing Context

HVHZ-rated products are tested under a specific protocol family. TAS 201 covers large-missile impact, TAS 202 covers cyclic wind-pressure loading, TAS 203 covers forced-entry resistance. When a product references HVHZ compliance, these are the tests it has passed. It’s the difference between a marketing claim and a documented engineering result.

Design Pressure for Your Wind Zone

Design pressure is matched to your specific wind zone, up to +/-100, never higher. Your home’s elevation, exposure category, and roof geometry determine the required rating. We pull the wind load calculation for your address and spec the window to meet it, no more. Over-specifying costs money without adding practical protection.

Energy Performance

Low-E and insulated glass options are available for thermal performance. In Miami’s cooling-dominated climate, Low-E coatings reduce solar heat gain without sacrificing visible light. Insulated glass units add a second air space to slow conductive heat transfer. These are optional upgrades layered onto the impact glazing, not replacements for it.

Color & Glass Options

Finish selection in Miami is as much about durability as it is about curb appeal. White and Almond are the traditional staples for ranches and cottages in neighborhoods like Westchester and Country Club Pines. Bronze and Black read more contemporary and hold up well on newer builds in Wynwood, Edgewater, and Midtown. Tan works beautifully on Mediterranean-style homes with barrel tile roofs, common throughout Coral Gables and Pinecrest.

Glass choice depends on orientation and exposure. Clear impact glass preserves the truest color rendition and is the most economical path to code compliance. Tinted glass cuts glare and solar gain on west-facing elevations that catch the afternoon Miami sun. Low-E insulated glass is the right choice for bedrooms and living areas where you want impact protection plus year-round comfort. Our team reviews your orientation and shading during the site visit so the glass package is matched to the room, not picked from a catalog default.

Installation by Winslow Windows & Doors in Miami

The best NOA-rated window underperforms if it’s installed wrong. We see it constantly in Miami: windows installed by crews who don’t understand HVHZ anchoring, or who skip the perimeter seal because it’s faster. The result is a window that passes the permit inspection but leaks at the first hard storm. The NOA rating applies to the full system: frame, glazing, anchoring, and sealant. Break any link in that chain and the rating is void.

Our installation follows the AAMA 2400 and 2410 standard practices for fenestration installation. Every window is set level, plumb, and square before anchoring, with shims placed at load-bearing points, never at the corners. We apply AAMA 812 low-expansion foam around the full perimeter to seal against air and water intrusion while allowing the frame to move naturally with wind load flex. Flashing details follow the opening type: block, wood frame, or poured concrete.

Miami adds layers of complexity. Coastal exposure means higher wind loads and salt-air corrosion concerns, which affects anchor type and finish selection. Permitting in Miami-Dade requires a signed and sealed product approval submittal, and we prepare the documentation so your permit isn’t held up. After installation, we run a final water test at the sill and head, then clean the opening. The site is left better than we found it.
