Product Overview - Single Hung Windows

Single hung windows are a workhorse profile in Florida residential construction. The upper sash stays fixed, and the lower sash slides up to ventilate. That fixed upper panel actually works in your favor structurally: fewer moving parts means fewer points where wind-driven rain can work its way in during a Palm Beach storm. The operable lower sash locks into the frame, and the entire unit is glazed with laminated impact glass built to hold together under impact.

These windows show up everywhere in Palm Beach County, from 1960s ranch homes in West Palm Beach getting their first impact upgrade to newer Mediterranean-style builds in Palm Beach Gardens and Jupiter. They fit the 2-over-1 and 1-over-1 lite patterns common in Florida architecture, and because the profile stays relatively slim, they don’t disrupt the look of an existing home the way a bulkier casement or awning might.

What makes the product durable in a coastal climate comes down to materials and engineering. The frames we install are extruded aluminum or multi-chamber vinyl, both of which hold up to salt air, intense UV, and the humidity cycles Palm Beach sees every summer. The glazing is laminated impact glass with a PVB interlayer, the same technology used in automotive windshields. When impact occurs, the glass may crack but the interlayer holds the pane in the frame, keeping the building envelope sealed. That’s the core of what an HVHZ-rated system is supposed to do.

TruePane Windows & Doors has installed single hung impact windows in homes from coastal high-rises in downtown West Palm Beach to canal-front properties in Boynton Beach. The profile works because it’s proven, it’s installable, and it doesn’t ask the homeowner to change the way their house looks.

Technical Specifications

• Frame materials: Aluminum, Vinyl. Aluminum offers a slim profile and high structural strength for larger openings. Vinyl offers thermal performance and a lower-maintenance finish. Both meet the structural demands of impact-rated configurations we specify in Palm Beach.
• Glass options: Laminated Impact Glass with a PVB Interlayer, Low-E Insulated Glass, Tinted Glass, Clear Glass. Impact glazing is the foundation; Low-E and tinted options layer in energy and glare performance.
• Finish options: White, Almond, Bronze, Black, Tan. These cover the finish palette we see across Palm Beach homes, from white coastal cottages to bronze-trimmed Mediterranean estates.
• Screen options: Half Screen, Full Screen. Half screens cover the operable lower sash only, which suits most single hung installations. Full screens are available where the opening style calls for it.
• Design pressure: Matched to your Palm Beach wind zone, up to +/-100, never higher. We don’t overspec for the sake of a bigger number; we spec what the structure requires.
• Compliance: Miami-Dade NOA and Florida Product Approval numbers available per configuration. Engineered to Florida Building Code High-Velocity Hurricane Zone requirements.

Hurricane & Compliance Performance

Laminated Impact Glass
The lite is built from two panes of glass bonded with a PVB interlayer. Under impact, the glass fractures but stays in the frame. That keeps wind, water, and debris outside the living space until the pane can be replaced. This is the single most important material choice in any Palm Beach impact window.

Miami-Dade NOA / FL Product Approval
Each configuration TruePane Windows & Doors specifies carries its own NOA or Florida Product Approval number. Approvals are issued per configuration, not per product family, so we verify the exact documentation against your specific quote and your municipality’s permit requirements.

FBC / HVHZ Compliance
Single hung units we install in Palm Beach are engineered to Florida Building Code High-Velocity Hurricane Zone requirements. HVHZ is the stricter of Florida’s two building regimes and applies throughout Palm Beach County. Product approval under HVHZ is not optional here; it’s the baseline.

TAS 201 / 202 / 203 Testing Context
HVHZ-rated products are tested under the TAS protocol family. TAS 201 covers large-missile impact resistance. TAS 202 covers cyclic wind-pressure loading, which simulates a hurricane’s repeated pressure cycles rather than a single gust. TAS 203 covers forced-entry resistance, which matters for home security as much as for windborne debris.

Design Pressure for Your Wind Zone
Every opening has a design pressure requirement based on its wind zone, building height, and location on the structure. We match the window to your required DP, up to +/-100 and never higher. Overspecifying beyond the requirement adds cost for zero performance gain; underspecifying is a code violation we will not do.

Energy Performance
Laminated impact glass can be paired with Low-E coatings and insulated glass construction in single hung configurations. Low-E reduces solar heat gain, which matters in Palm Beach where air conditioning runs most of the year. Tinted glass adds glare control for east- and west-facing openings.

Color & Glass Options

The five finish options, White, Almond, Bronze, Black, and Tan, cover nearly every exterior palette we see in Palm Beach. White and Almond dominate coastal-style homes and older concrete block construction in neighborhoods like El Cid and Flamingo Park. Bronze and Black show up on contemporary builds in Palm Beach Gardens and on Mediterranean-style homes where dark window frames echo wrought iron details. Tan bridges the gap on homes with sandy stucco or beige hardie exteriors.

Glass selection should follow the room. Clear laminated impact glass keeps sightlines clean and is the most common choice for living areas with good shading. Low-E insulated glass makes sense for large east and west-facing openings where afternoon sun drives cooling load. Tinted glass works well on waterfront properties with heavy glare, although it reduces visible light transmission, so we typically recommend it selectively rather than whole-home. Your TruePane Windows & Doors project manager will walk you through what each option does on your specific openings.

Installation by TruePane Windows & Doors in Palm Beach

How a window is installed matters as much as what the window is. A perfectly engineered HVHZ impact product installed without proper perimeter sealing, or set out of level, will leak and fail regardless of what its approval documentation says. That is why TruePane Windows & Doors handles every single hung installation in Palm Beach with a consistent process.

Before pulling the old window, we inspect the rough opening for rot, termite damage, and structural condition in the buck or concrete surround. We measure the opening in three places on each axis because Palm Beach block and wood-frame openings are rarely perfectly square after decades of settling. We set each unit level, plumb, and square before anchoring, and we shim only at manufacturer-specified points to avoid bowing the frame.

Perimeter sealing follows AAMA 812 practice using low-expansion foam, which fills the gap without distortion, followed by the exterior sealant system appropriate for the cladding. The full installation follows AAMA 2400/2410 standard practice for window installation. After the unit is anchored and sealed, we run a water test to confirm the perimeter is dry before trim and finish work resumes.

Palm Beach County is an HVHZ jurisdiction. That means your permit submittal will require product approval documentation specific to each configuration. TruePane Windows & Doors coordinates with your permitting path, whether that’s a city-level submittal in West Palm Beach or county review in unincorporated areas. Coastal exposure, wind zone, and building height all factor into the required design pressure, and we account for those on the front end, not during inspection.

Frequently Asked Questions - Single Hung Windows

What wind zone / design pressure is the Single Hung Windows rated for?
Single hung windows we install in Palm Beach are engineered for the wind zone of your specific property, with design pressures matched to your structure up to +/-100 and never higher. We determine the required DP from your building’s location, height, and opening size, then specify the configuration that meets it. Call (850) 801-5596 and we’ll work up the right spec for your home.

What is the lead time?
Lead times vary by manufacturer and configuration. Our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines each run on their own production schedules, and custom finishes or unusual sizes can extend timing. Once your order is placed, your TruePane Windows & Doors project manager will keep you updated on the production schedule and coordinate your install date. Call (850) 801-5596 for current lead time on the configuration you’re considering.

Does it require a Miami-Dade NOA or Florida Product Approval submittal for my permit?
Yes. Palm Beach County is an HVHZ jurisdiction, and your permit submittal will require the product approval documentation for your specific single hung configuration. TruePane Windows & Doors provides the NOA or Florida Product Approval numbers applicable to your exact window spec, size, and design pressure. We hand you documentation your permit expeditor or contractor can drop into the submittal without rework.

Can I customize the size or configuration?
Single hung impact windows are available in a broad range of standard sizes, and most manufacturers will build custom sizes within their approved parameters. Mullion configurations, rectangular or radius tops, and specialty shapes are generally possible but must be approved on a per-configuration basis since product approvals are tied to specific sizes and arrangements. Call (850) 801-5596 with your opening dimensions and we’ll tell you what’s approvable and what isn’t.

How do I maintain the frame?
Maintenance depends on the frame material. Aluminum frames need periodic cleaning of the track and weep holes, and touch-up of any finish scratches to prevent oxidation in Palm Beach salt air. Vinyl frames need the track vacuumed and the weatherstripping checked annually. The glass cleans with standard non-abrasive glass cleaner; avoid ammonia-based products that can degrade seals over time. We cover specific care at installation walkthrough.
