AfterDouble Hung Windows in Coral Gables, FL | Winslow Windows & Doors
Double hung windows are the classic vertical-glide profile Florida homeowners have trusted for generations, but along the coast near Coral Gables they have to do more than look traditional. They have to hold up. Our Double Hung Impact Series pairs the familiar top-and-bottom sliding sash design with laminated impact glass that’s engineered and tested for High-Velocity Hurricane Zone conditions. We install these across Coral Gables, from the Riviera and Hammock Oaks neighborhoods down to the waterfront streets near the Biltmore. Winslow Windows & Doors has been fitting these windows into Mediterranean, modern, and ranch-style homes throughout Coral Gables, FL for years. Call (904) 478-8983 and we’ll walk you through sizing, finish, and what your specific wind zone requires.
Product Overview - Double Hung Windows
Double hung windows are what most people picture when they think of a traditional Florida home: an upper sash that slides down, a lower sash that slides up, and a clean vertical line that fits older Coral Gables architecture without shouting. What makes this version different is what’s inside. These are classic vertical-glide impact windows with tilt-in sashes on both top and bottom. The traditional profile blends into the existing character of the home, while laminated impact glass does the work a shutter used to do. Both sashes tilt inward, which matters more than people realize - you can clean the exterior-facing glass from inside the house, and on a second-story Coral Gables bedroom window, that’s not a minor convenience. The frame options are aluminum or vinyl. Aluminum reads more architectural and crisp on Mediterranean and contemporary builds. Vinyl is the lower-maintenance choice that handles salt air well and appeals to homeowners watching the long-term cost. The common thread is the laminated impact glass protection built into every configuration.
Technical Specifications
Every double hung window we sell gets specified line by line on the quote, because the right combination of frame, glass, and finish depends on where in Coral Gables the home sits and what the wind zone demands. Here’s what’s available:
- Frame materials: Aluminum or Vinyl.
- Glass: Laminated Impact Glass with PVB interlayer, Low-E Insulated Glass, Tinted Glass, or Clear Glass.
- Frame finishes: White, Almond, Bronze, Black, Tan.
- Screen options: Half Screen or Full Screen.
- Design pressure: Matched to your wind zone, up to +/-100 - never higher.
- Compliance docs: Miami-Dade NOA and Florida Product Approval numbers available for your specific configuration.
Sizes are quoted per opening. Nothing is pulled off a shelf and forced to fit. We measure, we specify, and the window is built to that opening. That’s how a Coral Gables home with 1960s frame dimensions still ends up with a clean, code-compliant install.
Hurricane & Compliance Performance
Laminated Impact Glass - The core of the system is laminated glass with a PVB (polyvinyl butyral) interlayer. If a piece of debris strikes the glass during a storm, the interlayer holds the broken glass in the frame instead of letting it blow into the room. The window continues to keep the envelope closed while the storm passes. It’s the mechanism that makes hurricane-rated double hungs work without shutters.
Miami-Dade NOA and Florida Product Approval - These are the two compliance documents that matter in Coral Gables permitting. The NOA (Notice of Acceptance) and Florida Product Approval are issued per configuration. We’ll pull the exact numbers for your selected size, glass, and frame on your quote, and submit them with the permit package. No generic paperwork. It’s tied to your specific window.
FBC / HVHZ Compliance - The product line is engineered to Florida Building Code High-Velocity Hurricane Zone requirements. HVHZ is the stricter standard that applies down here in Miami-Dade County, and it governs everything from glass construction to anchoring. If your Coral Gables project is in an HVHZ jurisdiction, this window is built for that code path.
TAS 201 / 202 / 203 Testing Context - These refer to the testing protocol family HVHZ products are evaluated under. TAS 201 covers large-missile impact, TAS 202 covers cyclic wind-pressure loading, and TAS 203 covers forced-entry resistance. When a product carries an NOA in this region, it’s because it’s been put through that battery. We mention this so homeowners understand what’s behind the approval sticker, not just that one exists.
Design Pressure for Your Wind Zone - Design pressures are matched to your wind zone, up to +/-100 - never higher. The honest version is that not every Coral Gables home needs the maximum rating. A house a block off the water is in a different pressure zone than one right on Biscayne Bay. We’ll spec the right rating, and we won’t oversell a higher number just because it sounds safer.
Energy Performance Options - Low-E insulated glass packages are available for double hung windows, which means the impact protection and the thermal performance can coexist. In a Coral Gables climate with strong sun most of the year, Low-E makes a real difference in how the room feels near the glass. Tinted and clear options round out the lineup.
Color & Glass Options
Color is where a double hung either disappears into the house or anchors the whole facade. White is the most common finish in Coral Gables, especially when the window sits inside a stucco opening with architectural trim. Almond and Tan read warmer, which suits the clay roof and hand-troweled wall palette common in the older Mediterranean-style neighborhoods. Bronze and Black are the bolder choices, and they work surprisingly well on modern Coral Gables builds with clean stucco lines and an absence of heavy trim. On the glass side, clear laminated impact glass keeps the view neutral and tends to be the first choice when a window overlooks the water or a garden. Tinted glass steps in when the afternoon sun on a western-facing wall becomes a daily issue. Low-E insulated glass is the pick for bedrooms and west-facing rooms where heat gain through the glass is felt most strongly. All of these go through the same impact-rated glazing process.
Installation by Winslow Windows & Doors in Coral Gables
A window with a valid NOA only performs as designed if the installation is done correctly. That’s not a sales line; it’s the reality of how impact-rated fenestration works. The approval certifies a complete system, glass and frame together, and if the frame is twisted, shimmed badly, or sealed wrong, the system doesn’t match the tested condition. We install every double hung window level, plumb, and square against a prepared opening. We start with a pre-install inspection of the rough opening, the existing flashing condition, and the surrounding wall jamb. In a Coral Gables house with original wood framing or decades-old stucco, there’s usually something to correct before the window goes in. We use AAMA 812 low-expansion foam as the perimeter sealant, which is the right product for impact windows because it seals without bowing the frame. Our installation practice follows AAMA 2400 and 2410 standards, and we run a final water test before we call the job done. Permitting is part of this too. Coral Gables sits in an HVHZ jurisdiction, and the city checks product approvals carefully. We know what the permit reviewers here want to see, and the product submittal goes in with the application. We handle that for you. When the installation is on a waterfront block or a wide-open corner lot, the wind exposure is higher and the anchoring detail matters even more. That’s why we don’t sell these windows through a subcontracted crew we’ve never met. Our installers do this full time in Coral Gables and the surrounding Miami-Dade neighborhoods.
Frequently Asked Questions - Double Hung Windows
Design pressures are matched to your specific wind zone, up to +/-100 - never higher. The right number for your Coral Gables home depends on where the property sits relative to the coast and what the local wind zone maps say for your address. We’ll spec the correct rating on your quote and match it to the NOA documentation. Call (904) 478-8983 and we’ll pull your wind zone and give you a straight answer.
Lead time depends on the configuration, the size, and the finish. The manufacturer builds to order once we’ve locked the measurements and the spec, and production schedules vary by brand line. We’ll give you a realistic window when we quote, and we keep you posted if anything shifts. Call (904) 478-8983 to talk through current timelines for the configuration you’re considering.
Yes. Coral Gables sits in an HVHZ jurisdiction, and the city’s permit process expects the product approval documentation to accompany the application. The NOA and Florida Product Approval are issued per configuration, so we pull the specific numbers that match your selected size, glass, and frame, and we include them in the permit package. We handle that paperwork as part of the installation.
Yes, within the tested configurations available for each product line. These windows are made to order, so odd openings in older Coral Gables homes can usually be accommodated. The constraint is the tested approval: if a size or glass combination falls outside what the NOA covers, we won’t try to force it through. We’ll tell you what’s possible and what isn’t before you spend a dollar.
Both sashes tilt inward, so you can clean the glass and the sash tracks from inside your home, which is a real benefit on second-floor Coral Gables windows. Wipe the frame on a regular schedule: a soft cloth and mild soap keeps salt and grime from building up, and an occasional rinse of the track keeps the hardware moving. Aluminum frames need very little beyond a wash. Vinyl even less. Give us a call at (904) 478-8983 if the balance or tilt mechanism feels off; a quick adjustment is cheaper than a full hardware replacement.
