Single Hung Windows

Single Hung Windows in Westchester, FL | Winslow Windows & Doors

Single hung windows are a workhorse profile in Florida homes: a fixed upper sash, and a lower sash that slides up to open. When the lower sash carries laminated impact glass meeting HVHZ standards, you get a window that protects the house during a storm and still looks like a normal window the other 360 days of the year. Winslow Windows & Doors installs single hung impact windows across Westchester, FL every month, and we’ve seen firsthand how they perform in this wind zone.

Product Overview - Single Hung Windows

Single hung windows are one of the most common impact-rated replacement profiles in Florida homes for a reason. The design is simple: the top sash doesn’t move, and the bottom sash lifts vertically. Fewer moving parts than a double hung means fewer seals to maintain and a tighter baseline fit, which matters when a storm is pushing against the frame. In Westchester, where we sit close to the coast and inside a high-velocity hurricane zone, that structural simplicity translates to real protection.

We build these windows from aluminum and vinyl frames, depending on what your home’s architecture and budget call for. Aluminum gives you thinner sightlines and excellent rigidity on wider openings. Vinyl delivers strong thermal performance and never needs painting. Both frames get the same laminated impact glass package, which is what carries the actual NOA rating. The fixed upper sash carries large glass panels that won’t rack under wind load, and the operable lower sash has the hardware and balance system tuned for smooth daily use. It’s a profile that fits ranch homes, mid-century builds, 80s and 90s tract housing, and newer Mediterranean-style construction all across Westchester, FL.

Technical Specifications

Every single hung order is configured to the specific opening and wind zone. Here’s what you can choose from:

• Frame materials: Aluminum or vinyl, selected for the opening size and elevation requirements.
• Glass options: Laminated impact glass with a PVB interlayer, Low-E insulated glass, tinted glass, or clear glass. Laminated is standard for impact-rated openings; Low-E can be layered in for energy performance.
• Finish options: White, almond, bronze, black, and tan across both aluminum and vinyl lines.
• Screen options: Half screen or full screen, depending on how you ventilate the room.
• Design pressure: Matched to your wind zone, up to +/-100 PSF, never higher.
• Compliance: Miami-Dade NOA and Florida Product Approval numbers issued per configuration and verified on your written quote.

Hurricane & Compliance Performance

Here’s how this product holds up under Florida conditions, and the standards it answers to.

Laminated Impact Glass
Two panes of glass bonded with a PVB interlayer. When something hits the window, the glass cracks but the interlayer keeps the broken pieces held in the frame. No flying shards, no sudden pressure change inside the house. This is the core of the impact rating.

Miami-Dade NOA / FL Product Approval
Each configuration carries a Notice of Acceptance or Florida Product Approval number, issued per size and frame combination. These are the documents your local building department in Westchester will ask for on the permit application. We verify them on your quote before you sign anything.

FBC / HVHZ Compliance
Engineered to meet Florida Building Code High-Velocity Hurricane Zone requirements. HVHZ is the stricter windborne-debris standard that applies in Miami-Dade and nearby coastal zones, and our products are built to that bar, not the lower inland standard.

TAS 201 / 202 / 203 Testing Context
These windows are tested under the TAS protocol family: TAS 201 for large-missile impact, TAS 202 for cyclic wind-pressure loading, and TAS 203 for forced-entry resistance. That means the product has been shot with a lumber missile then cycled through pressure swings, not just checked on paper.

Design Pressure for Your Wind Zone
We match the design pressure rating to your specific wind zone, up to +/-100 PSF. Never higher. There’s no reason to pay for a rating your street doesn’t require, and no reason to buy one that falls short. We pull the wind zone for your Westchester address before quoting.

Energy Performance
Low-E and insulated glass options are available on single hung windows. Low-E coatings cut heat transfer through the glass, which keeps west-facing bedrooms and south-facing living areas cooler during a Florida summer. Pair Low-E with a white or almond vinyl frame and you’ll notice the difference in the room that gets afternoon sun.

Color & Glass Options

The finish you pick should match the house, not fight it. White and almond are the two most common finishes we install in Westchester, and both pair well with stucco, lap siding, or the painted block construction common throughout the area. Bronze and black frames suit Mediterranean and Spanish-style homes with darker trim, iron accents, or a more modern look. Tan works well on earth-toned homes and the sandy palette you see on many properties off Coral Way and Bird Road.

On glass, start with laminated impact glass and then decide how much you care about heat and glare. Tinted glass reduces brightness and some solar heat without going full Low-E. Clear glass gives you maximum natural light and the truest exterior color. Low-E insulated glass is the upgrade path for rooms that bake in the afternoon sun or sit under the AC ducts. If you’re not sure which glass belongs on which side of the house, we’ll look at the elevations with you during the measurement.

Installation by Winslow Windows & Doors in Westchester

A NOA-rated window only performs to its rating if it’s installed correctly. We’ve replaced windows in Westchester homes where the product itself was fine but the install leaked around the frame or wasn’t sealed properly against wind-driven rain. That’s what breaks a window’s performance, and it’s why we handle the installation in-house rather than subbing it out.

Our process starts with a pre-install inspection: we check the opening, measure the reveal, confirm the substrate, and note any water intrusion signs before the first screw goes in. Then we set each window level, plumb, and square, shimming as needed and anchoring to the structure per AAMA 2400/2410 practice. We seal the perimeter with AAMA 812 low-expansion foam, which fills voids without bowing the frame, and finish with backer rod and sealant on the exterior. Every job ends with a water test on the first window and a cleanup pass that leaves the room better than we found it.

In Westchester, we’re working in an HVHZ jurisdiction that pulls permits for window replacements. We’re familiar with the submittal requirements from the local building department, and we prepare the NOA and Florida Product Approval documents your permit needs. If you’re in a coastal exposure zone, the anchoring requirements change, and we handle that in the quote stage, not as a surprise on install day.

Frequently Asked Questions - Single Hung Windows

What wind zone and design pressure is the single hung window rated for?
Design pressures are matched to your specific wind zone, up to +/-100 PSF, never higher. We pull the wind zone for your Westchester address before quoting and configure the frame and glass to that requirement.

What is the lead time on a single hung window order?
Lead times vary by frame material, glass package, and manufacturer production schedules. Vinyl lines often run faster than custom aluminum. When we prepare your quote, we give you a realistic production window so you can plan the project start around it.

Do I need a Miami-Dade NOA or Florida Product Approval submittal for my permit?
In an HVHZ jurisdiction like Westchester, yes, the building department will ask for the product approval documents as part of the permit application. We provide the NOA or Florida Product Approval number per configuration on your quote, and the full document package when the permit is pulled.

Can I customize the size or configuration?
Most single hung orders are built to the opening, not picked from stock sizes. Aluminum frames offer more flexibility on wide or unusual openings, while vinyl lines work within the manufacturer’s size chart. We’ll tell you which frame material gives you the best fit for your specific measurements.

How do I maintain the frame and glass?
Wash the glass with soap and water, nothing abrasive. Keep the lower sash track free of sand and debris, which build up fast in Westchester. Wipe the weatherstripping annually and check the drip holes at the bottom of the frame. If a balance or lock feels stiff, call us before forcing it. Call (863) 251-5864 if something isn’t operating right.
