Double Hung Windows

Double Hung Windows in Plantation, FL | Sightline Windows & Doors Plantation

Double hung windows are the workhorse of Florida residential architecture. Two operable sashes slide vertically past each other, giving you control over airflow from the top, bottom, or both. In Plantation, where afternoon thunderstorms roll off the Everglades and hurricane season demands real protection, homeowners want that classic look with code-compliant impact resistance. At Sightline Windows & Doors Plantation, we install double hung impact windows across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines. Every unit carries laminated impact glass, Miami-Dade NOA or Florida Product Approval documentation, and engineering for High-Velocity Hurricane Zone construction. We’ve measured, quoted, and installed these windows in Plantation neighborhoods from Jacaranda Lakes to Plantation Acres. Call (754) 704-3597 to schedule your free on-site estimate.

Product Overview - Double Hung Windows

Our double hung impact windows keep the traditional profile that Plantation homeowners expect: divided-light styling options, equal sight lines, and that familiar vertical operation. Both sashes tilt inward for cleaning, which matters when your second-story windows face the pool patio or back up to a canal. The top sash drops down; the bottom sash lifts up. You get natural ventilation without the wide swing of a casement into outdoor living space.

What makes this profile suited to hurricane-prone construction starts with the frame. We offer aluminum and vinyl options, each engineered with reinforced corners and integrated drainage paths. The laminated impact glass with PVB interlayer sits in a thermally broken or structurally enhanced frame depending on material selection. When a branch hits at speed, the glass may spider, but the interlayer holds the shards in place and the frame keeps the envelope sealed.

Architecturally, double hung windows fit the Mediterranean and coastal contemporary styles common across Plantation. They work in single openings, stacked combinations, or flanking a fixed picture window. The vertical proportion suits narrow wall segments between rooms and the tall ceiling heights found in many Plantation homes built after 1990. Sightline Windows & Doors Plantation sizes each unit to the rough opening, not the other way around.

Hurricane & Compliance Performance

Laminated Impact Glass
The PVB (polyvinyl butyral) interlayer bonds two glass lites into a single assembly. Under impact, the outer lite may fracture, but the interlayer stretches and holds the glass in the frame. This maintains the pressure envelope and prevents wind-driven water intrusion. It’s the core technology behind every HVHZ-rated window we install in Plantation.

Miami-Dade NOA / Florida Product Approval
Each configuration carries its own Notice of Acceptance or Florida Product Approval number. These are not blanket certifications. When we quote your project, we specify the exact NOA or approval number that matches your frame material, glass package, and size. Your building department in Plantation or Broward County will see this on the submittal.

FBC / HVHZ Compliance
Engineered to Florida Building Code High-Velocity Hurricane Zone requirements. This means the entire assembly, frame, glass, hardware, and installation method, meets the stricter standard that applies to coastal Broward County. Not all impact windows qualify for HVHZ. Ours do.

TAS 201 / 202 / 203 Testing Context
HVHZ-rated products undergo the TAS protocol family: TAS 201 for large-missile impact (testing what happens when a 9-pound 2×4 hits the glass), TAS 202 for cyclic wind-pressure loading (simulating hours of buffeting), and TAS 203 for forced-entry resistance. These tests evaluate the assembly as installed, not components in isolation.

Design Pressure for Your Wind Zone
Design pressure is a PSF rating that measures how much wind load the window can withstand. We match the rating to your specific wind zone, up to +/-100 PSF. A home near the New River corridor faces different exposure than one inland near Broward Mall. We calculate correctly and never overstate.

Energy Performance Options
Low-E insulated glass reduces solar heat gain and improves U-factor. In Plantation, where summer cooling loads dominate, this option cuts the thermal transfer that makes west-facing rooms unbearable. Available as an upgrade on qualifying lines.

Color & Glass Options

Plantation’s architectural palette runs from white stucco Mediterranean to tan barrel-tile roofs to bronze-accented coastal modern. Our five standard finishes cover this range without custom-order delays.

White remains the default for Florida homes, reflecting heat and matching trim. Almond softens the contrast on cream-colored exteriors. Bronze and Black suit darker soffit and fascia details increasingly popular in Plantation’s newer construction. Tan bridges the gap on sand-finish stucco.

Glass selection depends on orientation and room function. Laminated impact glass is baseline for every HVHZ installation. Low-E insulated glass adds thermal performance for west and south exposures that take direct afternoon sun. Tinted glass reduces glare on water-view rooms in Plantation Isles or Jacaranda. Clear glass serves when code requires impact protection but the architect specified no coating. We’ll walk your home and recommend per opening.

Installation by Sightline Windows & Doors Plantation in Plantation

Even a perfectly engineered window fails if the installation cuts corners. In Plantation, where the building department knows HVHZ requirements intimately, improper installation can mean failed inspection, water intrusion, or voided compliance documentation.

Our process starts with a pre-install inspection. We measure each rough opening, check for square, and identify structural conditions that affect flashing detail. In older Plantation homes, especially those built before Andrew-era code changes, we often find rotted sill plates or inadequate header support. We flag these before the window arrives.

Setting is done level, plumb, and square. Shimming is structural, not cosmetic. We follow AAMA 2400/2410 installation standards, which specify how the frame interfaces with the wall, how fasteners penetrate, and how we manage thermal and structural movement. The AAMA 812 low-expansion foam perimeter sealant fills the gap between frame and rough opening, creating an air and water barrier that flexes with temperature swings.

After setting, we run a water test. Then we clean, protect the glass, and walk the homeowner through operation. For Plantation permits, we provide the NOA or Florida Product Approval submittal, engineered drawings if required, and coordinate inspection scheduling. We’ve worked with Broward County building officials long enough to know what documentation prevents delays.

Improper installation compromises the NOA-rated system. A frame torqued out of square stresses the glass. Missing foam sealant creates a path for wind-driven rain. Fasteners in the wrong location void the engineering. That’s why professional installation matters, and why Sightline Windows & Doors Plantation does not subcontract this work to unvetted crews.

Frequently Asked Questions - Double Hung Windows

What wind zone / design pressure is the Double Hung Windows rated for?
Design pressures are matched to your specific wind zone, up to +/-100 PSF. We calculate this from your address in Plantation, not guess. Call (754) 704-3597 for an exact rating on your quote.

What is the lead time?
Lead times vary by manufacturer line and current demand. PGT and CGI typically move faster than custom ECO configurations. We quote current lead times with every estimate and update you if factory schedules shift. Call (754) 704-3597 for today’s timeline.

Does it require a Miami-Dade NOA or Florida Product Approval submittal for my permit?
Yes. Every impact window installation in Plantation’s HVHZ jurisdiction requires documented product approval. We provide the specific NOA or Florida Product Approval number for your exact configuration with your quote package, ready for Broward County building department submittal. Call (754) 704-3597 to start your project.

Can I customize the size or configuration?
Yes, within each manufacturer’s available matrix. We offer standard sizes for faster turnaround and made-to-measure options for replacement openings or new construction with non-standard framing. Sightline Windows & Doors Plantation measures every opening before ordering. Call (754) 704-3597 to schedule measurement.

How do I maintain the frame?
For vinyl frames, wash with mild soap and water twice yearly; avoid abrasive cleaners that scratch the finish. For aluminum frames, inspect powder-coated surfaces annually for chips that could expose metal to salt air, especially on Plantation homes near canal exposure. Lubricate tilt latches and balance mechanisms with silicone spray. The tilt-in sashes make interior glass cleaning straightforward from inside the home. Call (754) 704-3597 if you notice operation issues.
