Double Hung Windows

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

Double hung windows give you the classic Florida look with real hurricane protection. Both sashes slide vertically and tilt inward for easy cleaning, while the laminated impact glass does the heavy lifting when a storm rolls toward Miami. We install these across PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, so you’re not locked into one manufacturer. TruePane Windows & Doors has built our reputation in Miami on HVHZ-compliant installations that pass inspection the first time. If you’re replacing old single-pane windows in Coral Gables, Coconut Grove, or Pinecrest, call (561) 956-2754 and we’ll walk you through your options.

Product Overview - Double Hung Windows

Double hung windows are the profile most Miami homeowners grew up with. The traditional vertical-glide design fits everything from 1950s ranch homes in Westchester to newer Mediterranean builds in Palmetto Bay. What makes this version different from the old wood windows you’re replacing is the engineering underneath the familiar look. The frames are extruded aluminum or vinyl, built rigid enough to hold laminated impact glass under storm loading without flexing. Both the top and bottom sashes tilt in, which means you can clean the exterior glass from inside your house – a real benefit on second-story Miami homes where ladder access is a hassle.

For hurricane-prone construction, the laminated glass is the core of the system. A PVB interlayer bonds two panes together, so if debris hits the window during a storm, the glass cracks but stays in the frame. Water, wind, and flying objects don’t get through. That’s the difference between cosmetic damage and a flooded living room. We’ve installed these in every corner of Miami-Dade County, from beachfront condos in Sunny Isles to inland homes in Kendall, and the performance is consistent when the installation is done right.

Architecturally, double hungs work where a sliding window looks wrong. Colonial, Key West, and Craftsman-style homes in Miami neighborhoods like Shenandoah and Morningside all benefit from the vertical proportions. They also give you ventilation control that sliders can’t match – you can open the top sash to let hot air escape while keeping the bottom closed for privacy.

Technical Specifications

Here’s what you can configure on a double hung window through TruePane Windows & Doors. We don’t push one frame material over another – the right choice depends on your home’s construction and your budget, and we’ll talk through it honestly when you get your quote.

• Frame materials: Extruded aluminum or vinyl. Aluminum gives you the slimmest sightlines and a more rigid frame for large openings. Vinyl offers better thermal performance and usually comes in at a lower price point.
• Glass options: Laminated impact glass with PVB interlayer (standard for impact protection), Low-E insulated glass (for energy performance), tinted glass (for glare and heat rejection), and clear glass (for maximum light transmission).
• Finish options: White, Almond, Bronze, Black, and Tan. These are baked-on finishes, not paint, so they hold up to the salt air along the Miami coast.
• Screen options: Half screen (covers the bottom sash opening) or full screen (covers the full opening). Both are removable from inside.
• Design pressure: Matched to your specific wind zone, up to +/-100 PSF. We never oversell a rating your home doesn’t need.

Hurricane & Compliance Performance

This is where the product earns its keep. Every double hung window we install in Miami carries documentation that meets the strictest code requirements in the country. Here’s what that actually means for your home:

Laminated Impact Glass
The laminated impact glass uses a PVB (polyvinyl butyral) interlayer sandwiched between two panes. Under impact, the glass fractures but the interlayer holds everything in place. Your home stays sealed against wind-driven rain and pressure changes even when the glass is broken. In Miami, that’s not a luxury – it’s what keeps a Category 3 storm from becoming an interior flood.

Miami-Dade NOA / Florida Product Approval
Each configuration we sell carries either a Miami-Dade NOA (Notice of Acceptance) or a Florida Product Approval number. These are issued per configuration, not blanket approvals, which means the exact size, frame, and glass combination on your quote has its own documentation. We provide the specific numbers with your estimate so your permit submittal goes through cleanly.

FBC / HVHZ Compliance
The product is engineered to Florida Building Code (FBC) High-Velocity Hurricane Zone (HVHZ) requirements. HVHZ applies to Miami-Dade and Broward counties and is the toughest wind standard in the state. If the window doesn’t meet HVHZ, it doesn’t go in a Miami home. Ours do.

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, and TAS 203 covers forced-entry resistance. These are the tests that simulate a 9-pound 2×4 hitting the glass at speed, followed by thousands of pressure cycles. Our double hung windows pass this gauntlet.

Design Pressure for Your Wind Zone
Design pressure is matched to your specific wind zone, up to +/-100 PSF. We never spec a higher rating than required because that’s wasted money – and we never go lower because that’s a code violation. Your wind zone depends on your exact Miami address, and we calculate it during the estimate.

Energy Performance Options
Low-E and insulated glass options are available for homes that want more than impact protection. Low-E coatings cut solar heat gain, which matters in Miami where the sun punishes west-facing windows all afternoon. Insulated glass adds thermal separation between panes, and you can combine Low-E with insulated construction on most lines.

Color & Glass Options

The five finish options cover the range of Miami’s architectural styles. White and Almond are the workhorses – white fits the classic Florida cottage look in Coconut Grove, while almond blends with the stucco tones on 1970s homes in Kendall. Bronze and Black read more contemporary and pair well with darker roof lines and modern landscaping. Tan splits the difference and works on homes with natural stone or travertine accents.

On glass, the choice comes down to what you’re trying to solve. Clear laminated impact glass maximizes natural light and is the most affordable impact option. Tinted glass cuts glare and heat gain – useful in high-rise units with full eastern or western exposure that bakes all afternoon. Low-E insulated glass is where homeowners in Miami get the best year-round comfort, because it handles the solar load without making the interior feel like a cave. We’ll help you balance cost and performance when you see the quoted options side by side.

Installation by TruePane Windows & Doors in Miami

A Miami-Dade NOA-rated window installed incorrectly is not a rated window anymore. The NOA approval depends on the entire assembly – frame, glass, anchorage, and perimeter seal – working together. That’s why our installation process follows AAMA 2400/2410 practice and why we use AAMA 812 low-expansion foam perimeter sealant on every opening. The foam seals the gap between the window frame and the rough opening, blocking water intrusion and air leakage while allowing just enough flexibility for thermal movement.

Every install starts with a pre-install inspection. We check the rough opening dimensions against the ordered window, verify the condition of the surrounding framing, and confirm the anchorage plan matches the NOA documentation. During installation, we set every window level, plumb, and square – if the frame is racked even slightly, the sashes bind and the seals don’t seat. After the window is anchored and the perimeter is foamed and flashed, we run a final water test on the finished opening before we call the job done.

Miami-specific permitting is part of what we handle. HVHZ jurisdictions require product approval submittals with the permit application, and we provide the NOA or Florida Product Approval numbers for your exact configuration. Coastal exposure in neighborhoods like Brickell, Edgewater, and Miami Beach affects wind zone calculations and sometimes requires higher design pressure ratings than inland areas. We know how to navigate that, and we make sure your paperwork matches your product.
