Single Hung Windows

Single Hung Windows in Fort Lauderdale, FL | Sightline Windows & Doors Fort Lauderdale

Single hung windows are the workhorse of Florida home protection. A fixed upper sash and an operable lower sash in laminated impact glass make this one of the most common impact-rated replacement profiles in Florida homes, and for good reason. The design is simple, proven, and built to take what our coastal weather delivers. At Sightline Windows & Doors Fort Lauderdale, we install single hung impact windows across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines for homeowners in Fort Lauderdale, Lauderdale-by-the-Sea, Coral Ridge, and throughout Broward County. Whether you’re replacing original 1970s aluminum windows or building new in a Fort Lauderdale coastal zone, we’ll match the right frame, glass, and finish to your project.

Product Overview - Single Hung Windows

The single hung profile has been a staple of Florida residential construction for decades. What makes it endure is straightforward engineering: the top sash stays fixed, creating a permanent weather barrier, while the bottom sash lifts vertically for ventilation. In our hurricane-impact versions, both sashes are glazed with laminated impact glass, so even the fixed upper unit contributes to the home’s protective envelope.

This profile suits Fort Lauderdale homes particularly well. The vertical operation fits narrow wall cavities common in mid-century ranch homes from Imperial Point to Melrose Park. The fixed upper sash reduces moving parts, which means fewer potential leak points over decades of salt-air exposure. And because the design is inherently simpler than double hung or casement systems, single hung windows often deliver more glass area per rough opening, which matters when you’re maximizing daylight in a Fort Lauderdale living room or bedroom.

We specify these across aluminum and vinyl frame options depending on your home’s architecture, your maintenance preferences, and your budget. Aluminum frames suit modern and coastal contemporary homes from Harbor Beach to Rio Vista, where slim sightlines and structural strength matter. Vinyl frames work well for traditional Florida ranch and Mediterranean Revival homes in neighborhoods like Coral Ridge Isles, where thermal performance and low maintenance are priorities. Both frame types accept the same laminated impact glass packages and finish colors, so you’re not trading safety for material choice.

Hurricane & Compliance Performance

Laminated Impact Glass
The PVB (polyvinyl butyral) interlayer holds glass fragments in the frame even after impact. If a wind-borne object strikes the window, the glass may crack but the interlayer maintains the barrier. This is what separates impact-rated windows from standard tempered glass in Fort Lauderdale homes.

Miami-Dade NOA & Florida Product Approval
Every configuration we sell carries its own Miami-Dade Notice of Acceptance and Florida Product Approval numbers. These aren’t blanket certifications. We verify the specific numbers on your quote so your permit submittal matches the exact product installed.

FBC / HVHZ Compliance
These windows are engineered to Florida Building Code High-Velocity Hurricane Zone requirements. Fort Lauderdale sits in HVHZ territory, so this isn’t optional. It’s the baseline for legal installation and insurance compliance in our market.

TAS 201 / 202 / 203 Testing
HVHZ-rated products undergo the full TAS protocol family: TAS 201 for large-missile impact resistance, TAS 202 for cyclic wind-pressure loading, and TAS 203 for forced-entry resistance. This is the testing context that underpins every NOA we reference.

Design Pressure Matched to Your Wind Zone
Design pressures are matched to your specific wind zone, up to +/-100 PSF. We never spec beyond what’s required for your Fort Lauderdale address. Over-specifying wastes money; under-specifying fails inspection. We calculate it right.

Energy Performance Options
Low-E insulated glass packages are available for energy performance beyond baseline impact glazing. In Fort Lauderdale’s cooling-dominated climate, this matters for west-facing walls and second-story installations that take afternoon sun.

Color & Glass Options

Our five standard finishes cover the architectural range we see across Fort Lauderdale neighborhoods. White and Almond remain the most requested for traditional Florida homes in Coral Ridge and Poinsettia Heights, where lighter colors reflect heat and blend with stucco exteriors. Bronze and Black have grown popular for modern coastal builds from Las Olas Isles to Sunrise Key, where darker frames create deliberate contrast against white or gray siding. Tan works well for Mediterranean Revival and Spanish Colonial homes in Rio Vista and Idlewyld, where earth tones complement tile roofs and coral stone accents.

Glass selection depends on orientation and use. Laminated impact glass with PVB interlayer is the standard for all Fort Lauderdale installations, it’s what’s tested and NOA-listed. Low-E insulated glass adds a thermal performance layer for rooms that struggle with heat gain, we often specify it for west-facing bedrooms in Victoria Park. Tinted glass suits garages, lanais, and utility spaces where you want impact protection with reduced visible light. Clear glass is available for interior-facing openings or where maximum light transmission is the priority. We’ll walk your home and recommend per opening rather than defaulting to one specification everywhere.

Installation by Sightline Windows & Doors Fort Lauderdale in Fort Lauderdale

A NOA-rated window is only as good as its installation. We’ve seen properly specified units fail because the opening wasn’t prepped to AAMA 2400/2410 standards, or because the perimeter seal was left to generic caulk instead of AAMA 812 low-expansion foam. That’s not how we work.

Our process starts with a pre-install inspection of every rough opening. In Fort Lauderdale’s older neighborhoods, from Dorsey-Riverbend to Shady Banks, we regularly find out-of-square block openings from original 1950s and 60s construction. We correct plumb and level before the window touches the opening. The frame is set square, shimmed to manufacturer’s specification, and fastened through the jamb or fin per the NOA detail, never through the sill where water can track.

The perimeter receives AAMA 812 low-expansion foam sealant, not backer rod and caulk. This creates a continuous thermal and air barrier that moves with the frame. We cap the exterior with approved flashing integrated to your home’s weather-resistant barrier. After installation, we run a water test on a sampling of units to verify no leakage at the sill or jamb corners.

Fort Lauderdale’s coastal exposure adds complexity. Homes east of Federal Highway, from Galt Ocean Mile down to Hollywood Beach, face salt spray and higher wind zones. We factor this into both product specification and installation detail. Permitting in Broward County requires HVHZ-compliant documentation, and we provide the NOA or Florida Product Approval submittal sheets your building department needs. We don’t leave you to figure out paperwork.

Improper installation voids the performance the NOA promises. A window rated to +/-100 PSF design pressure becomes a liability if the frame twists in the opening or the sill pan drains into the wall cavity. Our crews are trained specifically for Fort Lauderdale’s construction types, from concrete block to wood frame to CBS with stucco. The installation is where the engineering on paper becomes protection in practice.

Frequently Asked Questions - Single Hung Windows

What wind zone and design pressure is the Single Hung Windows rated for?
Design pressures are matched to your specific Fort Lauderdale wind zone, up to +/-100 PSF. We verify your address against the Florida Building Code wind speed map and specify accordingly. Call (754) 666-7478 for an exact rating on your home.

What is the lead time for single hung impact windows?
Lead times vary by manufacturer line, frame material, and current demand. PGT and CGI typically run 8-14 weeks; CWS, ES Windows, ECO, and Mr-Glass lines vary seasonally. We quote current lead times with every proposal so you can plan your project start. Call (754) 666-7478 for today’s availability.

Does my Fort Lauderdale permit require a Miami-Dade NOA or Florida Product Approval submittal?
Yes. Broward County and the City of Fort Lauderdale require HVHZ-compliant documentation for every impact window installed. We provide the specific Miami-Dade NOA or Florida Product Approval number for your exact configuration with your quote, ready for permit submittal. Call (754) 666-7478 and we’ll confirm your permit package.

Can I customize the size or configuration of single hung windows?
Yes. Single hung windows are available in standard and custom sizes across all six lines we carry. We measure every opening, account for your rough opening conditions, and specify the unit that fits. Custom sizes may extend lead time slightly. Call (754) 666-7478 to schedule measurement.

How do I maintain the frame and hardware?
For aluminum frames, wash with mild soap and water twice yearly, inspect weep holes for debris, and lubricate the sash lock and lift rail annually with silicone spray. For vinyl frames, avoid abrasive cleaners, use the same soap-and-water routine, and check the weatherstripping for compression set every few years. Salt buildup from Fort Lauderdale’s coastal air accelerates grime accumulation, so homes east of A1A may need quarterly rinsing. Call (754) 666-7478 if you notice operation stiffness or seal gaps.
