Product Overview - Single Hung Windows

A single hung impact window combines a fixed upper sash and an operable lower sash in laminated impact glass. That configuration has become a staple of Florida replacement work for practical reasons: fewer moving parts than a double hung, a tighter air seal when closed, and a price point that makes whole-house replacement realistic for West Palm Beach homeowners. The lower sash lifts vertically and can be tilted inward on most lines we carry for easy cleaning from inside the home, which matters when you’re dealing with second-story windows on a Flagler Drive waterfront property.

The frame options we order most often for West Palm Beach jobs are aluminum and vinyl. Aluminum gives you a slimmer sightline and handles the salt air along the Intracoastal well when properly finished. Vinyl delivers excellent thermal performance and resists the kind of surface pitting that coastal exposure can cause over years. Both frame materials accept laminated impact glass with a PVB interlayer, which is the core of the hurricane-rated assembly. We also offer Low-E insulated glass, tinted glass, and clear glass depending on your orientation and how much South Florida sun hits a given elevation. Architectural fit matters here: single hung windows read as traditional on the Ranch-style homes in Southland Park, the Mediterranean designs in Sunshine Park, and the mid-century builds scattered through Old Northwood. If you’re replacing original single pane aluminum windows from the 1960s or 1970s, a single hung impact window often drops into the existing rough opening with minimal interior disruption.

Durability comes from the lamination itself. The PVB layer bonds two panes of glass together, so even under large-missile impact the glass holds in the frame rather than shattering into the living space. Combined with a properly sealed perimeter and a sill design that sheds water, you have a window that performs year after year in West Palm Beach’s humidity and storm cycles. We recommend this profile for bedrooms, living areas, and anywhere you want an operable window without the added cost of a second moving sash. Call (561) 264-1279 and we’ll walk you through which line fits your home and budget.

Technical Specifications

Here’s what goes into every single hung impact window we order for West Palm Beach installations. Specific configurations vary by manufacturer line, so we verify exact specs on your quote rather than quoting generic published ranges.

• Frame materials: Aluminum or vinyl, selected for salt-air resistance and thermal performance
• Glass options: Laminated impact glass with PVB interlayer, Low-E insulated glass, tinted glass, clear glass
• Finish options: White, almond, bronze, black, and tan
• Screen options: Half screen (covers the operable lower sash only) or full screen (covers the full opening)
• Sash operation: Lower sash lifts vertically; upper sash fixed in place
• Design pressure: Matched to your wind zone, up to +/-100, never higher than your opening requires
• Compliance: Miami-Dade NOA and Florida Product Approval numbers available per configuration; engineered to FBC HVHZ requirements

We order these windows opening-by-opening. Your quote includes the design pressure rating per window, the applicable approval numbers, and the glass package we recommend for each elevation. No guesswork, no overselling products you don’t need for your specific West Palm Beach wind zone.

Hurricane & Compliance Performance

Six things matter when you’re evaluating single hung impact windows in West Palm Beach. Here’s what each one actually means for your home.

Laminated Impact Glass - Two panes of glass bonded with a PVB interlayer. Under impact, the glass cracks but stays in the frame. That means no breach in your envelope during a storm, and no glass shards blowing through your living room. This is the same lamination approach used across Florida’s HVHZ-rated window products. It’s the layer that makes the window impact-rated, not just wind-rated.

Miami-Dade NOA / Florida Product Approval - Every configuration we order carries Miami-Dade Notice of Acceptance or Florida Product Approval documentation. Numbers are issued per configuration, meaning a specific approval corresponds to a specific frame, glass package, size range, and design pressure. We pull the exact NOA or FL approval for your window sizes and include it with your permit submittal. No generic certificates, no “similar product” substitutions.

FBC / HVHZ Compliance - High-Velocity Hurricane Zone requirements under the Florida Building Code are the strictest in the state. Single hung windows we install in West Palm Beach are engineered to meet HVHZ standards, which govern everything from glazing attachment to anchoring. Your permit reviewer will look for this compliance language specifically.

TAS 201 / 202 / 203 Testing Context - HVHZ-rated products are tested under a specific protocol family. TAS 201 covers large-missile impact, where a lumber projectile is fired at the glass. TAS 202 covers cyclic wind-pressure loading, which simulates the repeated push-pull of hurricane-force wind. TAS 203 covers forced-entry resistance. When a product carries an NOA, it has passed testing under this protocol stack. That’s the standard your single hung windows will meet.

Design Pressure for Your Wind Zone - Every opening has a required design pressure based on its location on the building and the wind zone mapped for your West Palm Beach address. We order windows matched to that requirement, up to +/-100. We never spec a higher design pressure than your opening calls for because it adds cost without adding protection. Your quote shows the design pressure per window, sized to the actual wind load math.

Energy Performance Options - Low-E and insulated glass options are available across the single hung lines we carry. In West Palm Beach, that’s primarily about solar heat gain: east and west elevations get hammered by afternoon sun, and Low-E coatings reduce the heat that enters your home. We’ll recommend glass packages by elevation, not by a generic one-size-fits-all formula.

Color & Glass Options

Finish selection in West Palm Beach is partly aesthetic and partly practical. White and almond remain the most common choices for the coastal, Mediterranean, and Key West-inspired homes throughout the city. They read as traditional, stay cooler to the touch in direct sun, and blend with the light stucco tones you see from South End to Northwood. Bronze and black finishes have gained traction on more contemporary builds and on homes where the windows are meant to read as strong architectural lines against a lighter facade. Tan splits the difference: warm enough for Mediterranean elevations, muted enough not to demand attention.

Glass choice depends on where the window faces. Clear laminated impact glass is the baseline, giving you maximum visible light without tint. Tinted glass cuts down glare and solar heat gain, useful on west-facing bedrooms that get blasted from 3 pm to sunset. Low-E insulated glass is the energy performer: the Low-E coating reflects heat while the insulating air space slows conductive transfer, which matters when your AC runs ten months out of the year in West Palm Beach. We’ll help you match glass packages to each elevation so you’re not paying for Low-E on a shaded north wall or skipping it on a sun-baked west elevation. Every glass option is available as laminated impact glass with the PVB interlayer intact, because the impact rating is non-negotiable in this market.

Installation by TruePane Windows & Doors in West Palm Beach

An NOA-rated window is only as good as the installation around it. We’ve seen improperly flashed openings fail water tests in West Palm Beach’s afternoon storms, and we’ve seen windows set out of plumb that bind when you try to lift the sash. Neither should happen on a hurricane-rated product. Our installation process starts before we ever remove an old window: we inspect the rough opening, check for rotted framing or compromised sill conditions, and verify the anchoring surface will hold the fasteners the NOA requires. West Palm Beach’s older homes, especially in neighborhoods like Grandview Heights or Flamingo Park, often have framing conditions that need attention before a new window goes in.

Then we set the frame level, plumb, and square. That’s not a slogan; it’s the foundation of a window that operates correctly for decades. We shim and anchor per the manufacturer’s approved installation method, seal the perimeter with AAMA 812 low-expansion foam, and follow AAMA 2400/2410 practice for the full installation sequence. Flashing, head flashing, sill pans where the opening calls for them, and a final water test to confirm the seal. We pull the permits and submit the NOA or Florida Product Approval documentation with your application, because West Palm Beach and Palm Beach County permitting departments check for HVHZ compliance on every opening. Improper installation compromises the rated system. A window that passed TAS 201 in a lab can fail in your wall if the perimeter seal is skipped or the anchoring is short. That’s why professional installation matters, and why we treat every opening as a compliance exercise, not just a swap-out. Call (561) 264-1279 if you want an installation crew that treats your West Palm Beach home like the code official will.
