Single Hung Windows

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

Single hung windows are one of the most common impact-rated replacement profiles we install in Florida homes. The design is simple: a fixed upper sash that never moves, and a lower sash that slides up to open. For Westchester homeowners, that fixed upper panel is a structural advantage. There’s less moving hardware, fewer seal points, and a cleaner line against coastal wind and rain. Winslow Windows & Doors has installed this profile across PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass product lines throughout Westchester, and we set every unit level, plumb, and square so the NOA rating actually performs the way the engineering intended.

Product Overview - Single Hung Windows

Single hung windows are built around a fixed upper sash and an operable lower sash, both fitted with laminated impact glass. That fixed top panel does more than reduce moving parts. It gives the window a continuous glass-to-frame bond across the upper half of the opening, which means fewer points where wind-driven rain or flying debris can find a weakness during a storm.

In hurricane-prone construction, this profile works particularly well in two places. First, on elevations with limited wind exposure where a full casement or horizontal roller isn’t required by the homeowner. Second, in bedrooms, hallways, and secondary spaces where simple operation matters more than maximum ventilation. We see single hung units specified all over Westchester, from single-story ranches near Bird Road to newer two-story builds off Coral Way.

What makes the product durable isn’t one feature. It’s the combination of a rigid frame, laminated glass that holds together under impact, and a lower sash that rides on smooth, adjustable balance hardware. Winslow Windows & Doors offers the profile in aluminum and vinyl, depending on the look and budget you’re after. Aluminum gives a slimmer sightline and higher rigidity for large openings. Vinyl delivers strong thermal performance and resists the salt-and-humidity exposure common across Westchester.

For replacement work, this is often the most cost-effective way to bring an older home up to current Florida Building Code standards without changing the look of the house. The window drops into standard rough openings, which keeps labor cleaner and faster.

Technical Specifications

• Frame materials: Aluminum, Vinyl - both available in impact-rated configurations. Aluminum for narrow sightlines and large spans; vinyl for thermal efficiency and coastal durability.
• Glass options: Laminated impact glass with a PVB interlayer; Low-E insulated glass; tinted glass; clear glass.
• Finish options: White, Almond, Bronze, Black, Tan - powder-coated or factory-applied finishes matched to your interior and exterior trim.
• Screen options: Half screen or full screen. Half screens cover the operable lower sash only; full screens span the entire opening for a cleaner look when the window is open and the upper sash stays glass only.
• Design pressure: Matched to your wind zone, up to +/-100. We never specify a higher design pressure than your structure needs.
• Compliance: Miami-Dade NOA and Florida Product Approval numbers are issued per configuration. Verification happens on your specific quote, not on a generic spec sheet.

Hurricane & Compliance Performance

Laminated Impact Glass - The glass assembly uses a PVB (polyvinyl butyral) interlayer sandwiched between glass lites. When a wind-borne object strikes, the glass may crack, but the interlayer holds the broken pieces in the frame. The opening stays sealed. Water and wind don’t enter through the glass plane during the storm.

Miami-Dade NOA / FL Product Approval - Single hung configurations from our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines carry Miami-Dade Notice of Acceptance and Florida Product Approval documentation. These are issued per configuration, meaning the exact size, glass make-up, and frame material on your quote gets its own approval number. We verify that for you before permitting.

FBC / HVHZ Compliance - The product is engineered to Florida Building Code High-Velocity Hurricane Zone requirements. That means the design, anchoring, and glazing were validated for use in the wind-borne debris region that includes Westchester and most of Miami-Dade County.

TAS 201 / 202 / 203 Testing Context - HVHZ-rated products are tested under a specific protocol family. TAS 201 covers large-missile impact testing. TAS 202 covers cyclic wind-pressure loading. TAS 203 covers forced-entry resistance. Together they simulate what a real storm does to a window over hours, not seconds.

Design Pressure for Your Wind Zone - Design pressures are matched to your wind zone, up to +/-100, never higher. Specifying a higher pressure than required isn’t better; it often means a heavier, more expensive product that doesn’t improve real-world safety. We match the rating to the elevation, opening size, and exposure on each window, not the other way around.

Energy Performance - Low-E and insulated glass options are available for this product. For Westchester homes with western or southern exposure, an insulated Low-E make-up cuts daytime heat gain and keeps the AC from running as hard. The impact rating stays intact because the laminated outer lite is what carries the storm performance.

Color & Glass Options

Finish selection in Westchester usually comes down to the house style. White and Almond are the standard choices for older ranches and condos with painted stucco. Bronze works well on mid-century builds where darker trim already exists. Black is the current choice for new construction and modern renovations, especially with clean white walls. Tan sits quietly on Mediterranean and Spanish-style homes, which are common south of Coral Way.

Glass selection depends on exposure and comfort goals. Clear laminated impact glass gives you the storm performance with maximum visible light. Tinted glass reduces glare on east and west-facing rooms. Low-E insulated glass is the pick for anyone trying to lower cooling costs, because it cuts heat transfer without darkening the room. Every option carries the same PVB interlayer in the laminated lite, so you’re not trading impact performance for energy efficiency.

We’ll walk you through the finish and glass pairings on your specific elevations when we measure. It’s easier to match when you’re standing in front of the opening with sample chips in hand.

Installation by Winslow Windows & Doors in Westchester

An NOA-rated window only performs to its rating when the installation matches the testing. We’ve seen failed window retrofits in Westchester where the glass was fine but the perimeter seal leaked, or the frame was racked out of square because the rough opening wasn’t prepped. The design pressure numbers don’t mean anything if the anchor points and sealant lines aren’t done correctly.

Our process starts with a pre-install inspection of each opening. We check the rough opening dimensions against the approved product size, look for moisture damage in the jambs, and verify the substrate can accept the anchors. We don’t just pull the old sash and set the new frame.

Every unit is set level, plumb, and square. That’s not a slogan. It’s the first thing we check with a laser and a 6-foot level because a racked frame binds the lower sash, wears the balances, and breaks the weather seal over time. We follow AAMA 2400 and 2410 installation practice, and we seal the full perimeter with AAMA 812 low-expansion foam before applying the exterior sealant line. Low-expansion foam is the key detail: it fills the shim space without bowing the jambs.

After the frame is set and the sashes are installed, we run a final water test on each opening before interior trim goes back. That catches sealant gaps before they become drywall stains. If your Westchester home is in an HVHZ jurisdiction, we also coordinate the NOA and Florida Product Approval submittal with your permit package so the inspection pass isn’t a surprise.

Improper installation compromises the entire NOA-rated system. A window that passes the impact test in the lab can fail in a storm because of bad anchoring or skipped sealant. That is the single strongest reason to use a professional installer on this product.
