Double Hung Windows

Double Hung Windows in Boca Raton, FL | Winslow Windows & Doors

Double hung windows give you the traditional vertical-glide look that suits so many Boca Raton homes, but in our South Florida climate they have to do more than look right. They need to hold up under hurricane conditions. Our impact-rated double hung windows pair the classic two-sash profile with laminated impact glass, so you get the architectural character you want and the protection the Florida Building Code demands. Winslow Windows & Doors installs these systems across Boca Raton, Delray Beach, Deerfield Beach, and surrounding Palm Beach County communities. We carry impact double hungs from PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass, and our crews install to HVHZ standards on every single job. Call (561) 816-5648 to talk through your project.

Product Overview - Double Hung Windows

The double hung window is one of the most recognizable profiles in American residential architecture. Both the top and bottom sashes slide vertically, which means you can open either half for ventilation. What makes this version different from what you’d find up north is the glass package and the hardware engineering behind it. These are impact windows built for hurricane-prone construction, not just a coastal aesthetic.

In Boca Raton, double hungs show up everywhere: in the original 1970s ranch homes along Camino Real, in the Mediterranean-style builds in Royal Palm Yacht & Country Club, and in newer construction throughout West Boca. Homeowners like them because they tilt inward for cleaning, which matters when salt air and pollen build up on the glass faster than anywhere else in the state. The classic vertical-glide movement fits both traditional and transitional elevations.

We offer these in aluminum and vinyl frames. Both materials are engineered to accept laminated impact glass and to resist the repeated wet-dry cycles that eat away at lesser window systems in coastal South Florida. The tilt-in sashes on both top and bottom make maintenance straightforward: you release the sash, tip it into the room, and wipe both sides of the glass from inside the house. No ladders, no exterior washing, no arguing with a squeegee on a second-story sill.

For Boca Raton specifically, the double hung impact window works well in bedrooms, living rooms, and anywhere you want cross-ventilation without the horizontal track of a sliding window. The traditional profile keeps HOA and architectural review boards happy in communities that restrict contemporary window styles.

Double Hung Windows - Technical Specifications

Here are the material, glass, finish, and screen options available on the double hung impact windows we install in Boca Raton. Every configuration gets matched to your specific wind zone during the estimate process.

• Frame materials: Aluminum or Vinyl. Aluminum offers a slimmer sightline and a more architectural profile; vinyl offers strong thermal performance and a lower maintenance surface.
• Glass options: Laminated impact glass with a PVB interlayer (standard for hurricane protection), Low-E insulated glass (for energy performance), tinted glass (for glare and heat control), and clear glass (for maximum visible light).
• Finish options: White, Almond, Bronze, Black, and Tan. These five finishes cover most exterior and interior color schemes across Boca Raton’s housing stock.
• Screen options: Half screen or full screen. Half screens cover the lower sash only; full screens cover the entire opening.
• Size range: Custom configurations are available. We’ll verify maximum and minimum dimensions for your specific product during the estimate, since size limits vary by frame material and design pressure rating.
• Sash operation: Both sashes operate vertically and tilt in for cleaning. Locking hardware engages between the sashes at the meeting rail.
• Approvals: Miami-Dade NOA and Florida Product Approval numbers are issued per configuration. We’ll confirm the exact approval numbers listed on your project quote.

Hurricane & Compliance Performance

Impact windows in Florida live and die by their testing and approvals. Here’s what matters for the double hung windows we install in Boca Raton, and what each performance feature actually does for your home.

Performance Features

• Laminated Impact Glass - The glass package uses a polyvinyl butyral (PVB) interlayer sandwiched between glass panes. When the outer pane takes a hit, the PVB interlayer holds the glass in the frame, keeping the window sealed and the envelope intact. This is the core mechanism that separates impact-rated double hungs from standard windows that shatter on first impact and let wind-driven rain into the house.
• Miami-Dade NOA / Florida Product Approval - These windows carry Miami-Dade Notice of Acceptance and Florida Product Approval numbers, issued per exact configuration. That means the specific size, frame material, glass package, and hardware combination you order has been evaluated and approved by the state. We verify the approval numbers that apply to your quote before you sign anything.
• FBC / HVHZ Compliance - The double hung systems we install are engineered to Florida Building Code High-Velocity Hurricane Zone requirements. HVHZ is the strictest wind-borne debris region in the state, and it governs most of Palm Beach County east of the turnpike, including all of coastal Boca Raton.
• TAS 201 / TAS 202 / TAS 203 Testing Context - HVHZ-rated products are tested under the TAS protocol family. TAS 201 covers large-missile impact, meaning the window gets hit with a length of lumber fired at speed and must remain intact. TAS 202 covers cyclic wind-pressure loading, which simulates sustained hurricane-force winds pushing and pulling on the glass and frame. TAS 203 covers forced-entry resistance. Our double hung impact windows are built and approved within this testing framework.
• Design Pressure Matched to Your Wind Zone - Design pressures are matched to your wind zone, up to +/-100, never higher. Design pressure (DP) is a PSF rating of how much wind load the window and frame assembly can withstand. We don’t sell a higher DP than your home needs, because over-specifying doesn’t add protection, it just adds cost. Your estimate will specify the exact DP rating required for your property.
• Energy Performance Options - Low-E and insulated glass options are available on these double hungs. Low-E coatings reduce solar heat gain through the glass, which matters in Boca Raton where the sun beats on east and west elevations for most of the afternoon. Insulated glass adds an air space for better thermal separation between your conditioned interior and the outside air.

Color & Glass Options

The finish you choose on an impact window has to satisfy two audiences: your HOA or community design review board, and your own eye from the interior. The five standard finishes we offer on these double hungs are White, Almond, Bronze, Black, and Tan. That palette covers the overwhelming majority of Boca Raton architecture.

White and Almond read clean and classic on the coastal and shingle-style homes you see in communities like Boca Isles and The Oaks. Bronze and Black create contrast on lighter stucco exteriors and match the dark mullion aesthetic popular in contemporary Mediterranean and modern builds. Tan works well on earth-toned stucco and the softer beige exteriors common in central and south Boca Raton neighborhoods.

On the glass side, the choice comes down to what you’re trying to solve. Clear laminated impact glass maximizes visible light, which matters in rooms that already feel dark or face a shaded side of the house. Tinted glass cuts glare and solar heat gain, which is worth considering on western exposures that bake from 2 to 6 p.m. Low-E insulated glass keeps the heat out and the AC load down, particularly on larger glass areas. And every option still carries the PVB interlayer that gives the window its impact rating.

Installation by Winslow Windows & Doors in Boca Raton

An NOA-rated impact window only performs as rated if the installation is done correctly. The product approval applies to the window assembly and the installation method as a system. A window that’s set out of level, under-sealed, or poorly flashed will fail at the perimeter long before the glass ever takes a hit. That’s why the install crew matters at least as much as the product brand.

Our installation process for double hung windows in Boca Raton starts with a pre-install inspection of the rough openings. We measure every opening independently before we order, because South Florida concrete block construction shifts over time and openings are never perfectly square. The window gets set level, plumb, and square in the opening. Then we seal the perimeter per AAMA 2400/2410 installation practice, using AAMA 812 low-expansion foam perimeter sealant to form a continuous air and water seal between the frame and the rough opening. After the interior and exterior trim go back, we run a final water test on every window before we consider the job done.

In Boca Raton, there are a few things that make installation more demanding than average. Coastal exposure means the sealant joints have to be perfect, because salt-laden wind will find any gap and work it open over time. The wind zone in east Boca is a serious factor in the engineering of fasteners and anchoring. And if you’re in a structure built under modern code, the permit process will require product approval submittals, which we handle as part of the project. Improper installation compromises the NOA-rated system, which is exactly what we’re not going to let happen on your home.
