Double Hung Windows

Double Hung Windows in Palm Beach, FL | Winslow Windows & Doors

Double hung windows remain one of the most requested profiles we install in Palm Beach because they do two jobs at once. They preserve the clean, traditional look that fits so many Florida homes, and they carry laminated impact glass that holds together when debris hits. Both sashes tilt inward for easy cleaning, which matters when salt air and summer storms leave their mark on coastal glass. Winslow Windows & Doors has installed impact-rated double hung units across Palm Beach, from older ranch-style homes near the Intracoastal to newer Mediterranean builds in developments west of I-95. If you’re pricing new windows for an HVHZ project, call (561) 831-7863 and we’ll walk you through product options, lead times, and what your specific opening will require.

Product Overview - Double Hung Windows

Impact-rated double hung windows keep a classic vertical-glide operation and add the protection Florida building codes demand. The top and bottom sashes both slide vertically, and both tilt in for cleaning from inside the home. That’s a practical advantage in Palm Beach, where second-story windows over pool decks and landscaping can be hard to reach from the exterior. The traditional profile sits comfortably in older Florida architecture, yet the laminated impact glass and reinforced frame deliver the performance of a modern hurricane product.

We offer these windows in aluminum and vinyl. Aluminum remains the most common choice for coastal Palm Beach because it holds tight tolerances over decades and accepts a wide range of powder coat finishes. Vinyl suits budget-conscious projects where thermal performance is the priority, though it carries the same impact glazing options. What makes the impact-rated double hung distinct from a standard double hung is what you cannot see: the laminated glass package with its PVB interlayer, the heavier sash construction, and the hardware designed to handle wind load cycling. The window looks traditional. It performs like a tested opening protection system. Winslow Windows & Doors installs this product across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, so we can recommend the right manufacturer based on your opening sizes, finish needs, and project timeline.

Technical Specifications

• Frame materials: Aluminum or vinyl, selected for the building type and coastal exposure.
• Glass options: Laminated impact glass with a PVB interlayer, Low-E insulated glass, tinted glass, or clear glass, depending on orientation and energy goals.
• Finish options: White, almond, bronze, black, and tan across both frame materials, subject to manufacturer availability.
• Screen options: Half screen for a clean lower-sash look or full screen for whole-opening ventilation.
• Operation: Both sashes glide vertically and tilt inward for cleaning and maintenance access.
• Sizing: Built to order for each rough opening. We field-verify every measurement before the order is released.
• Compliance documentation: Miami-Dade NOA and Florida Product Approval numbers provided per configuration on your quote.

Every double hung order is configured to the opening, the wind zone, and the design pressure requirement. There is no off-the-shelf unit on a Palm Beach permit package. We quote each opening individually so the product delivered matches the product submitted.

Hurricane & Compliance Performance

Laminated Impact Glass
The glass makeup uses a PVB (polyvinyl butyral) interlayer sandwiched between panes. Under impact, the glass may fracture but the interlayer holds the broken pieces in the frame, keeping wind and water out of the building envelope. This is the core mechanism behind Florida impact-rated glazing and the foundation of the double hung’s HVHZ performance.

Miami-Dade NOA / Florida Product Approval
Miami-Dade NOA (Notice of Acceptance) and Florida Product Approval numbers are published per configuration and verified against your specific quote. Because these documents attach to exact sizes, glass choices, and frame combinations, we confirm the submittal package applies to your openings before the permit goes in.

FBC / HVHZ Compliance
The product is engineered to Florida Building Code (FBC) High-Velocity Hurricane Zone (HVHZ) requirements. HVHZ is the stricter code tier that governs Palm Beach County and Miami-Dade. A window that passes FBC but not HVHZ testing will not satisfy a Palm Beach permit reviewer. We work exclusively with configurations that carry the proper HVHZ documentation.

TAS 201 / 202 / 203 Testing Context
HVHZ-rated impact products are tested under the TAS protocol family. TAS 201 covers large-missile impact, TAS 202 covers cyclic wind-pressure loading that simulates storm buffeting, and TAS 203 covers forced-entry resistance. These tests exist because failures in real hurricanes are rarely a single event. They are a cycle of impact, pressure, and fatigue.

Design Pressure for Your Wind Zone
Design pressures are matched to your wind zone, up to +/-100, never higher. Design pressure is a PSF rating that describes the structural load the window is built to resist, not a wind speed label. We request the wind zone and exposure category for your address before we finalize any quote. The number on the NOA must line up with the number on the permit drawing, and we make sure it does.

Energy Performance
Low-E and insulated glass options are available for energy performance. On west-facing elevations in Palm Beach, a Low-E insulated package reduces solar heat gain noticeably. Tinted glass suits owners who want daylight without the full glare. The glass choice does not reduce the impact rating, it adds a layer of thermal control on top of it.

Color & Glass Options

Finish options shift with the architecture you already have. White and almond remain the workhorse colors for Palm Beach ranch homes and Key West style cottages. Bronze and black read well on Mediterranean facades with tile roofs and stucco walls, and they hide dirt better on busy roadfronts. Tan splits the difference, working well on homes that lean neither fully cool nor fully warm. Aluminum frames take these finishes as a powder coat that stands up to coastal air far better than wet paint.

Glass selection comes down to orientation and how you live in the house. Clear laminated impact glass preserves the truest view and works well on shaded elevations. Tinted glass reduces glare, which matters on east-facing bedrooms and west-facing living areas in Palm Beach. Low-E insulated glass is the energy move, and it is the default recommendation for any room that runs the air conditioning hard from March through October. The PVB interlayer remains the constant across all of these: no matter the glass performance choice, the impact protection stays.

Installation by Winslow Windows & Doors in Palm Beach

A Miami-Dade NOA means nothing if the window in your wall was not installed the way the tested assembly was built. We see this problem regularly in Palm Beach when homeowners inherit windows from a previous owner and discover leaks around the frame five years in. The product was fine. The install was not.

Our process starts with a pre-install inspection of every opening. We look for rotted buck framing, out-of-square rough openings, and existing water intrusion paths before the old window ever comes out. Then we set each unit level, plumb, and square, shimming per the approved anchoring schedule rather than filling gaps with whatever is in the truck. The perimeter gets an AAMA 812 low-expansion foam sealant, applied to give the assembly the air and water seal the NOA rating assumes. Our installation practice follows AAMA 2400/2410 standards for flashing and integration with the wall system.

Palm Beach brings two local conditions that shape the work. First, coastal exposure means wind-driven rain finds every gap that a rushed install leaves behind. Second, HVHZ jurisdictions in Palm Beach County review the product submittal and the installation method as one package. The permit reviewer wants to know that the anchor, the sealant, and the flashing all match the tested assembly. We know what those packages require because we submit them regularly. After the install, each window gets a water test and a final inspection walk with you. Cleanup happens the day we finish, not the day after.
