Single Hung Windows

Single Hung Windows in Delray Beach, FL | TruePane Windows & Doors

Single hung impact windows are one of the most common replacement profiles we install in Delray Beach homes. The design pairs a fixed upper sash with an operable lower sash, both glazed in laminated impact glass. You get the look of a traditional Florida window with the protection a coastal property actually needs. TruePane Windows & Doors installs single hung units across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines. We’ve been leveling, plumbing, and squaring impact windows in Palm Beach County long enough to know that the install is what makes or breaks the rating.

Product Overview - Single Hung Windows

A single hung window operates from the bottom sash only. The top sash stays fixed in the frame. That’s the entire mechanical premise, and it’s exactly why this profile works so well in hurricane-prone construction: fewer moving parts, fewer breach points, and a cleaner seal around the glass. When both sashes carry laminated impact glazing, the whole unit becomes a rated barrier rather than just a window.

In Delray Beach, we see single hung units most often on ranches, mid-century concrete block homes, and the Mediterranean-style builds common in neighborhoods like Lake Ida, Tropic Isles, and Seagate. The narrow sightlines fit those architectural styles without calling attention to themselves. Homeowners tend to choose this profile when they want impact protection without the heavier visual weight of a casement or the wider tracks of a horizontal roller.

The frame materials we order in are aluminum and vinyl. Aluminum gives you a slim profile and holds finish color well under Florida sun. Vinyl costs less and insulates better at the frame edge. Both can be built to carry laminated impact glass, and both can be configured with Low-E insulated glass for energy performance. The lower sash glides on a track system we spec for repeated daily use, not just occasional operation.

We stock and order single hung impact windows in sizes that match existing rough openings throughout Delray Beach’s housing stock, from 1950s block homes near Old School Square to newer construction west of I-95. If your opening is a true custom size, we handle that through our manufacturer relationships, not by cutting corners on the frame.

Technical Specifications

• Frame materials: Aluminum or vinyl, chosen for the opening, exposure, and finish you want.
• Glass types: Laminated impact glass with PVB interlayer, Low-E insulated glass, tinted glass, or clear glass. Laminated impact glass is the base for every rated unit we sell.
• Finish colors: White, almond, bronze, black, and tan. Most Delray Beach homes we work on go white or bronze, though black has gained real traction on modern coastal builds in recent years.
• Screen options: Half screen or full screen. Half screens cover the operable lower sash. Full screens span the entire opening.
• Design pressure: Matched to your wind zone, up to +/-100. We never spec a unit above what the engineering calls for; over-specifying costs you money and buys you nothing.
• Compliance paperwork: Miami-Dade NOA (Notice of Acceptance) and Florida Product Approval numbers are issued per configuration, and we verify the exact numbers on your quote before you sign anything.

Hurricane & Compliance Performance

Laminated Impact Glass
The glass assembly uses a PVB (polyvinyl butyral) interlayer sandwiched between panes. When impact hits, the glass may crack, but the interlayer holds the fractured pane in the frame. That’s the mechanism that keeps wind and water from entering the home during a storm. It also makes forced entry significantly harder, which matters year-round in Delray Beach, not just in hurricane season.

Miami-Dade NOA / Florida Product Approval
Each configuration carries its own Notice of Acceptance and Florida Product Approval numbers. These are product-specific, not brand-level marketing claims. We pull the exact numbers for your specific size, frame, and glass combination and include them on your quote and permit package.

FBC / HVHZ Compliance
The units are engineered to Florida Building Code High-Velocity Hurricane Zone requirements. Delray Beach sits within a jurisdiction that enforces HVHZ standards, so every single hung window we install here must meet that bar. We do not sell non-compliant product into this market.

TAS 201 / TAS 202 / TAS 203 Testing Context
HVHZ-rated products are tested under a protocol family that includes TAS 201 for large-missile impact, TAS 202 for cyclic wind-pressure loading, and TAS 203 for forced-entry resistance. These tests simulate debris striking the glass and the pressure cycles that follow a breach attempt. The product is engineered to pass them in the configurations we quote.

Design Pressure for Your Wind Zone
Design pressure gets matched to your specific wind zone, up to +/-100, never higher. A home on the intracoastal in Delray Beach faces different loading than one tucked inland off Linton Boulevard. We verify the right DP for your address rather than quoting a generic number.

Energy Performance Options
Low-E and insulated glass options are available for single hung impact units. The Low-E coating reduces heat transfer through the glass, which matters in Delray Beach where afternoon western exposure bakes bedrooms and living rooms. Tinted glass is another option for glare control without resorting to window film.

Color & Glass Options

White is the default choice for most Delray Beach homes, and it works. It keeps sightlines crisp against stucco and matches most existing trim. Almond and tan suit older Florida ranches and some Mediterranean exteriors where a softer warm tone reads better than a stark white. Bronze has held steady among homeowners who want contrast on lighter walls. Black frames are the fastest-moving finish on new construction and modern coastal remodels in Delray Beach, particularly on homes with clean stucco lines and minimal trim.

On the glass side, clear laminated impact glass gives you the most neutral view and the truest color transmission. Tinted laminated glass cuts glare and adds daytime privacy, which is why we recommend it for east-facing rooms that catch the morning sun off the Atlantic. Low-E insulated glass is the pick when energy performance is the priority: it combines the impact resistance of laminated outer glass with an insulating air space and Low-E coating. In a Delray Beach bedroom that’s exposed to direct sun for six hours a day, that combination makes a measurable difference in how the room feels by mid-afternoon.

Installation by TruePane Windows & Doors in Delray Beach

An impact window only performs to its NOA rating if it’s installed correctly. That is not a sales line; it’s the engineering reality of how these systems work. The anchor pattern, the shim placement, and the perimeter seal are all part of the rated assembly. Get any of it wrong, and the window is no longer the product the manufacturer tested.

Our process in Delray Beach starts with a pre-install inspection of the rough opening. We check the condition of the buck, the surrounding substrate, and any existing water damage before we order the window. Then we set the unit level, plumb, and square, using shims at the anchor points specified by the manufacturer. The perimeter gets sealed with AAMA 812 low-expansion foam installed per AAMA 2400/2410 practice. That foam is the air and water barrier between the frame and the structure; it’s not trim filler, and we treat it that way.

We water-test the installation before interior trim goes back on. If water finds a path in, we find it then, not after the first heavy summer thunderstorm. Finally, our team handles the permitting awareness piece for you: Delray Beach is an HVHZ jurisdiction, and the Building Department will want to see your Florida Product Approval or Miami-Dade NOA numbers on the permit package. We provide them with your quote.

Coastal exposure adds another layer in Delray Beach. Homes east of Federal Highway sit in a more aggressive wind zone than homes west of Congress Avenue, and the design pressure requirement changes accordingly. We quote to your specific address, not a county-wide average. Improper installation compromises the NOA-rated system and the Building Department’s inspector will catch sloppy work. TruePane Windows & Doors works to a standard that passes inspection the first time because we’ve done it hundreds of times in this city.
