Geometric & Shaped Windows

Geometric & Shaped Windows in Boca Raton, FL | Winslow Windows & Doors

Geometric and shaped windows bring architectural personality to a home, and in Boca Raton they show up everywhere from Mediterranean-inspired Mizner estates to contemporary waterfront builds in Royal Palm Yacht & Country Club. But in a High-Velocity Hurricane Zone, a triangular or hexagonal opening isn’t something you can fill with off-the-shelf glass. Winslow Windows & Doors custom-fabricates triangular, hexagonal, octagonal, arched, and radius impact-glass configurations through our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, so the shape you drew on the elevation plan actually holds up when wind pressure climbs.

Product Overview - Geometric & Shaped Windows

Geometric and shaped windows are exactly what the name implies: impact-rated windows fabricated to non-rectangular profiles. Think triangular gable-end units, hexagonal accent windows above a front door, octagonal windows in a vaulted ceiling, eyebrow arches over French doors, half-rounds, quarter-rounds, and parallelogram units that follow a staircase. In Florida construction, these shapes traditionally created a problem. Builders wanted the look; code required impact protection; standard rectangular impact windows didn’t fit the opening. The answer is custom fabrication, where every layer of the window, the frame extrusion, the laminated glass, the glazing bead, is cut and assembled to the actual template of the opening, not pulled from stock.

What makes a shaped impact window suited to hurricane-prone construction is the same thing that makes any impact product work: the glass stays in the frame, and the frame stays in the wall. A missile hits, the PVB interlayer stretches and absorbs the energy, and the window remains a sealed barrier against wind-driven rain and pressure cycling. The difference with a geometric unit is that the engineering doesn’t stop at a rectangular stress model. Each leg of a triangle, each curve of an arch, each angle of an octagon carries load differently, so our fabricators re-evaluate the design pressure for the actual shape, not a nearest-size rectangle. That’s why these are always custom-fabricated to your opening, with design pressures matched to your wind zone, up to +/-100, and never higher. Call (561) 816-5648 and we’ll walk your opening from template to finished installation.

Technical Specifications

Here’s what goes into every geometric and shaped window we order and install in Boca Raton:

• Frame materials: Aluminum or vinyl. Aluminum carries the heavier spans and holds tighter tolerances on sharp angles; vinyl suits smaller decorative units and offers strong thermal performance.
• Maximum size: Custom-fabricated to order. We template the actual rough opening in your wall, so the window matches what’s built, not the other way around.
• Glass options: Laminated impact glass with PVB interlayer, Low-E insulated glass, tinted glass, clear glass. Glass selection depends on orientation, code requirements, and your energy priorities.
• Color and finish options: White, almond, bronze, black, and tan. These five finishes cover most Boca Raton exteriors, from stark white contemporary elevations to warm sand-toned Mediterranean stucco.
• Compliance: Miami-Dade NOA and Florida Product Approval numbers available per configuration, engineered to FBC High-Velocity Hurricane Zone requirements.
• Design pressure: Matched to your wind zone, up to +/-100. Never higher.

Because every geometric unit is a one-off, the quote you receive carries the specific compliance documentation for your exact dimensions and glass package. No generic cut sheets.

Hurricane & Compliance Performance

Laminated Impact Glass (PVB Interlayer). The core of the product. Two panes of glass bonded with a polyvinyl butyral interlayer that holds the glass in the frame under impact. When a projectile strikes, the glass cracks but stays put, keeping wind and water out of your Boca Raton home. This is the layer that makes a shaped window an impact window, not a decorative one.

Miami-Dade NOA / Florida Product Approval. Every geometric and shaped configuration carries a Miami-Dade Notice of Acceptance and Florida Product Approval number issued for that specific configuration. Verify the numbers on your quote. These approvals are the documentation your building department and permit reviewer look for in HVHZ jurisdictions like Boca Raton.

FBC / HVHZ Compliance. The products are engineered to Florida Building Code High-Velocity Hurricane Zone requirements, the standard that governs most of Palm Beach County’s coastal construction. Boca Raton enforces HVHZ provisions, so this isn’t a nice-to-have. It’s the pass-fail line for your permit.

TAS 201 / TAS 202 / TAS 203 Testing Context. HVHZ-rated products are tested under the TAS protocol family. TAS 201 covers large-missile impact, TAS 202 covers cyclic wind-pressure loading, and TAS 203 covers forced-entry resistance. Together they simulate what a window endures during a storm and after it, including the security concern of a vacated home.

Design Pressure for Your Wind Zone. Design pressure is the structural rating, expressed in PSF, that tells you how much wind load the unit is engineered to carry. Geometric and shaped windows from Winslow Windows & Doors are fabricated with design pressures matched to your wind zone, up to +/-100. Never higher. Your specific number depends on opening size, shape, and where the unit sits on the building envelope.

Energy Performance Options. Low-E insulated glass is available for shaped configurations, adding a thermal break and a low-emissivity coating that reflects heat while letting light through. For a west-facing octagon window in Boca Raton, Low-E insulated glass can meaningfully reduce solar gain without changing the exterior look. Tinted and clear glass remain available where code or preference calls for them.

Color & Glass Options

The five finish options, white, almond, bronze, black, and tan, map cleanly onto Boca Raton’s dominant architecture. White and black suit the modern spec homes going up in Boca East and the clean-lined renovations along the Intracoastal. Almond and tan belong on the stucco Mediterranean and Spanish-revival homes common in Old Floresta and neighborhoods west of I-95, where a bright white frame would fight the facade. Bronze splits the difference, offering a darker profile without the severity of black.

Glass choice follows both code and comfort. Laminated impact glass with a PVB interlayer is the structural backbone, required for any HVHZ-compliant opening. From there, adding Low-E insulated glass improves thermal performance, which matters on a large fixed geometric window that takes direct afternoon sun. Tinted glass reduces glare and visible light transmission, a popular choice for shaped units in media rooms, stairwells, and foyers where you want the shape without the heat. Clear glass maximizes the view and lets the architecture do the talking.

Installation by Winslow Windows & Doors in Boca Raton

A Miami-Dade NOA is only as good as the installation behind it. A shaped impact window that’s set out of square, shimmed unevenly, or sealed with the wrong perimeter product won’t perform the way the lab tested it. That’s why Winslow Windows & Doors installs every geometric and shaped unit to AAMA 2400/2410 standard practice, and why our crew doesn’t rush the template step.

The process starts with a pre-install inspection of the rough opening. We measure each leg, angle, and curve, and we compare the actual opening to the fabrication drawings before any demo begins. From there, the unit is set level, plumb, and square. On a shaped window, that matters even more than on a rectangle, because a small angular error compounds over the span of an arch or the legs of a gable triangle. We apply an AAMA 812 low-expansion foam perimeter sealant at the frame-to-wall interface, then complete the exterior sealant detail per the product’s tested assembly. After installation, we run a water test on the full perimeter and walk the interior and exterior with you before we call the job done.

Boca Raton has its own considerations. Coastal exposure means higher design pressure along the barrier island and the Intracoastal reaches. The city enforces HVHZ permitting, which means your window package and installation must satisfy the local building official, not just the manufacturer. We’ve installed geometric impact windows across Boca Raton, from Mizner Park-adjacent condos to gated communities like The Oaks and St. Andrews, and we know what the reviewers here expect to see in a permit submittal. Improper installation compromises the NOA-rated system, which is the whole reason you bought an impact window in the first place.

Frequently Asked Questions - Geometric & Shaped Windows

What wind zone / design pressure is the Geometric & Shaped Windows rated for? Design pressures are matched to your specific wind zone, up to +/-100 PSF, and never higher. The exact rating depends on the shape, size, and location of the unit on your home. We’ll confirm the number on your quote in writing. Call (561) 816-5648 for an exact figure on your opening.

What is the lead time on a custom geometric or shaped window? Lead time runs longer than stock rectangular units because the unit is fabricated to your template from the start. Plan for the fabrication window we give you at quote time and keep it in your project schedule, especially if the opening is tie-in condition for stucco or trim work. We’ll lock the production date with the manufacturer once you approve the drawings. Call (561) 816-5648 and we’ll give you a current lead-time estimate for your configuration.

Does it require a Miami-Dade NOA or Florida Product Approval submittal for my permit? Yes. In Boca Raton and other HVHZ jurisdictions, your permit package typically needs the Miami-Dade NOA and Florida Product Approval numbers for the specific configuration you’re installing. We provide that documentation with your quote so your permit set is complete before the first inspection. Call (561) 816-5648 and we’ll pull the approvals for your exact dimensions.

Can I customize the size or configuration? That’s the entire point of the product. Every geometric and shaped window we install in Boca Raton is custom-fabricated to the actual rough opening in your wall. Triangles, hexagons, octagons, arches, radius units, parallelograms, all built to your dimensions, within the structural limits of the frame material and glazing package. Bring us the drawings and we’ll engineer it. Call (561) 816-5648 to start.

How do I maintain the frame? Maintenance is straightforward: wash the glass with mild soap and water, keep the frame tracks and weep holes clear of debris, and inspect the perimeter sealant annually, especially after storm season. Don’t use abrasive cleaners or pressure wash the frames. If you ever spot a sealant gap or a fogged insulated unit, call us and we’ll take a look. Questions about your specific finish?
