Product Overview - Geometric & Shaped Windows

Standard rectangular windows don’t fit every wall. In Fort Lauderdale, where Mediterranean Revival, coastal contemporary, and custom architect-designed homes line the Intracoastal and fill neighborhoods from Coral Ridge to Harbor Beach, shaped openings are often the defining visual element of a façade. Our geometric and shaped impact windows answer that design need with full HVHZ-rated protection.

We fabricate triangular units for peak gables, hexagonal and octagonal configurations for tower rooms and entryways, and curved or radius-top shapes for arched openings. Every unit starts with your field measurements or architectural drawings. Because these are custom-fabricated to order, there’s no forcing a stock size into an irregular opening and hoping the seal holds. The frame materials, aluminum or vinyl, are cut and joined to the exact angle or radius specified. Laminated impact glass with a PVB interlayer is cut to match, then glazed into the frame as a complete assembly.

The result is architectural detail that doesn’t sacrifice wind-zone protection. In Fort Lauderdale’s coastal exposure, where design pressures run high and inspectors know what they’re looking for, that distinction matters. We’ve installed these units in homes from Las Olas Isles to Victoria Park, and the common thread is always the same: the homeowner wanted something visually specific, and they weren’t willing to trade storm protection to get it.

Hurricane & Compliance Performance

Laminated Impact Glass with PVB Interlayer

The glass in our geometric and shaped units isn’t tempered or anneled standard glazing. It’s laminated with a polyvinyl butyral interlayer that holds the glass in the frame even after impact. If a wind-borne object strikes the window, the glass may crack, but the interlayer keeps the assembly intact and the envelope sealed. That’s the core of hurricane-rated protection in Fort Lauderdale.

Miami-Dade NOA and Florida Product Approval

Every configuration we quote carries its own Miami-Dade Notice of Acceptance and Florida Product Approval numbers. These aren’t blanket certifications. They’re issued per specific frame material, glass type, size range, and anchoring method. When you receive your quote from Sightline Windows & Doors Fort Lauderdale, the NOA and FL Product Approval references for your exact geometry will be listed. Your permit office in Fort Lauderdale or Broward County will need them.

FBC High-Velocity Hurricane Zone Compliance

These units are engineered to Florida Building Code High-Velocity Hurricane Zone requirements. Fort Lauderdale sits in one of the most stringently regulated wind zones in the country. Generic “hurricane resistant” labeling isn’t enough here. The product must meet FBC-HVHZ specifically, and ours do.

TAS 201, 202, and 203 Testing Protocol

The testing context for HVHZ-rated products is the TAS protocol family: TAS 201 for large-missile impact resistance, TAS 202 for cyclic wind-pressure loading, and TAS 203 for forced-entry resistance. Our geometric and shaped configurations are tested and certified under this protocol suite. When we say a unit is rated, we mean it has passed the specific tests that Fort Lauderdale building officials recognize.

Design Pressure Matched to Your Wind Zone

Design pressure is a PSF rating, not a wind speed. We match the design pressure to your specific wind zone, up to +/-100 PSF. We never rate higher than necessary. An oversized rating doesn’t add protection; it adds unnecessary frame weight and cost. Our Fort Lauderdale team calculates the correct DP for your exposure, elevation, and proximity to open water.

Energy Performance Options

Low-E insulated glass is available for geometric and shaped units where thermal performance matters. In Fort Lauderdale’s climate, Low-E coatings reduce solar heat gain without the visual distortion of heavy tinting. For west-facing gables or unshaded stairwells, this option can meaningfully reduce cooling load.

Color & Glass Options

Our five standard finishes - White, Almond, Bronze, Black, and Tan - cover the palette we see most requested in Fort Lauderdale architecture. White and Almond remain popular for coastal Mediterranean and Bermuda-style homes, where lighter frames complement stucco and coral stone. Bronze and Black have gained ground in contemporary and transitional designs, particularly in neighborhoods like Rio Vista and Lauderdale-by-the-Sea where dark-framed window walls are part of the aesthetic. Tan splits the difference, working with both traditional and updated exteriors.

Glass selection depends on orientation and function. Clear glass maximizes visible light and views, appropriate for shaped windows installed primarily for architectural effect. Tinted glass reduces glare and solar heat gain, useful for large curved or polygonal units facing south or west. Low-E insulated glass adds thermal performance for conditioned spaces behind the window. The laminated impact glass with PVB interlayer is the baseline for all configurations - it’s not optional in HVHZ installation, it’s the foundation everything else builds on.

Installation by Sightline Windows & Doors Fort Lauderdale in Fort Lauderdale

A Miami-Dade NOA-rated window is only as good as its installation. We’ve seen geometric units fail in Fort Lauderdale homes not because the product was deficient, but because the opening wasn’t prepped correctly, the frame wasn’t leveled, or the perimeter seal was skipped. That’s why our installation process is as specific as the products we sell.

We start with a pre-install inspection of the rough opening. For shaped windows, this is critical. A radius-top or octagonal frame has less tolerance for out-of-square conditions than a rectangle. We measure diagonals, check the sill for level, and verify the opening against the shop drawings before the unit leaves our shop.

Setting is done level, plumb, and square, with shimming at structural points that match the NOA anchoring schedule. We follow AAMA 2400/2410 installation standards, which define how fenestration interfaces with the wall system in residential construction. The perimeter seal uses AAMA 812 low-expansion foam sealant, applied to create both an air barrier and a water-managed drainage plane. We don’t caulk over gaps; we fill them properly.

After setting, we run a final water test on every unit. In Fort Lauderdale’s coastal exposure, with salt air and driving rain, a perimeter that looks sealed can still leak under pressure. We check before we leave. Cleanup and protection of finishes follow.

Permitting awareness matters in HVHZ jurisdictions. Fort Lauderdale and unincorporated Broward County both require Miami-Dade NOA or Florida Product Approval submittals for impact window permits. We provide the specific documentation for your configuration with every quote, so your contractor or you can pull the permit without chasing paperwork. We’ve worked with local inspectors long enough to know what they want to see.

Frequently Asked Questions - Geometric & Shaped Windows

What wind zone and design pressure is the Geometric & Shaped Windows rated for?

Design pressures are matched to your specific wind zone, up to +/-100 PSF. We engineer each unit to the exact exposure requirements of your Fort Lauderdale location, never overrating or underrating the assembly. Call (754) 666-7478 for a site-specific assessment and exact DP for your quote.

What is the lead time for custom geometric or shaped windows?

Lead times vary by manufacturer line, configuration complexity, and current production schedules. Custom-fabricated shaped units typically require longer lead times than standard rectangles because they’re cut and assembled to your specific angles or radius. We’ll give you a realistic production window when we quote, and we coordinate delivery to avoid holding up your Fort Lauderdale project schedule.

Does my permit require a Miami-Dade NOA or Florida Product Approval submittal?

Yes. Fort Lauderdale and Broward County HVHZ jurisdictions require documented product approval for all impact-rated fenestration. We provide the specific Miami-Dade NOA and Florida Product Approval numbers for your exact configuration with your quote, formatted for permit submittal. This is not a generic certificate; it’s tied to your frame material, glass type, and anchoring method.

Can I customize the size, shape, or configuration?

Every geometric and shaped window we sell is custom-fabricated to order. Triangular, hexagonal, octagonal, curved, radius-top, and combined configurations are all available in sizes engineered to your opening. There is no standard catalog of shaped windows; each unit is built from your measurements or architectural drawings. Call (754) 666-7478 to schedule a field measurement.

How do I maintain the frame and glass?

Rinse frames quarterly with fresh water to remove salt buildup, especially in Fort Lauderdale’s coastal exposure. Wash glass with mild soap and water; avoid abrasive cleaners on tinted or Low-E surfaces. Inspect weep holes annually to ensure drainage paths stay clear. The laminated impact glass and finish are built for this climate, but basic maintenance extends both appearance and function.
