Geometric & Shaped Windows

Geometric & Shaped Windows in Miami, FL | Winslow Windows & Doors

Triangular, hexagonal, octagonal, arched, radius, and fully custom curved windows change the look of a home. They turn a blank wall into a focal point, flood an entryway with natural light, and give a modern Miami build or a Mediterranean revival real architectural character. The challenge in South Florida has always been finding someone who can fabricate these shapes as true hurricane-rated impact systems, not decorative add-ons. Winslow Windows & Doors specializes in exactly that. We custom-order Geometric & Shaped Windows from PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass, then install them to Miami-Dade HVHZ standards across Miami, FL.

Product Overview - Geometric & Shaped Windows

A geometrically shaped window is not a stock item. Every triangle, hexagon, octagon, trapezoid, half-round, eyebrow arch, or true radius is fabricated to order, matched to the exact rough opening we measure on site. What makes these profiles work in hurricane-prone construction is the same engineering that protects a standard impact window: laminated glass with a PVB interlayer, a heavy-duty aluminum or vinyl frame, and fastening that transfers wind load into the surrounding structure. The shape changes. The protection doesn’t.

Where do these windows belong? A tall triangular window above a front door in Coral Gables. A row of octagonal openings high on a gable in Coconut Grove. A curved glass feature capturing Biscayne Bay views from a master suite in Brickell. We’ve installed shaped units in Pinecrest, Kendall, Palmetto Bay, and across greater Miami, and in each case the window became the first thing people notice about the room. Because every unit is custom-fabricated to your opening, there is no compromise between the shape you want and the wind-zone protection Miami-Dade requires. Winslow Windows & Doors handles the measuring, ordering, permitting documentation, and installation so the finished product matches the drawing and the code.

Technical Specifications

Every Geometric & Shaped Window we order is built around your exact dimensions and the performance requirements of your specific Miami wind zone. Nothing about this product line is one-size-fits-all.

• Frame materials: Extruded aluminum or solid vinyl. Aluminum carries the heavier spans and slimmer sightlines many architects want on shaped openings; vinyl offers a lower-maintenance, thermally efficient alternative.
• Maximum size: Custom fabricated to order. Practical size limits depend on the shape, frame material, and design pressure your wind zone demands. We confirm all of this during measurement.
• Glass options: Laminated impact glass with PVB interlayer, Low-E insulated glass, tinted glass, or clear glass. Combinations are available, such as tinted laminated or Low-E insulated impact glass.
• Finish options: White, Almond, Bronze, Black, and Tan. These are standard architectural finishes that sit comfortably on both modern and traditional Miami homes.
• Compliance documentation: Miami-Dade NOA and Florida Product Approval numbers, issued per configuration, included with your submittal package.

Design pressure is matched to your wind zone, up to +/-100, and never higher than what your specific opening requires. We don’t over-engineer and we don’t under-deliver.

Hurricane & Compliance Performance

Shaped glass gets tested and rated just like any other impact window we sell. Here’s what makes these units perform in Miami-Dade’s High-Velocity Hurricane Zone.

Laminated Impact Glass
The foundation of every impact-rated shaped window is laminated glass with a PVB (polyvinyl butyral) interlayer. When windborne debris strikes, the glass may crack, but the interlayer holds the fractured pieces in the frame. The opening stays sealed against wind and rain, keeping the building envelope intact during the storm.

Miami-Dade NOA / Florida Product Approval
Each Geometric & Shaped Window configuration carries a Miami-Dade NOA (Notice of Acceptance) and Florida Product Approval number. These are issued per configuration, so your specific size, shape, and glass package gets its own documentation. We pull the applicable numbers for your quote and your permit submittal package.

FBC / HVHZ Compliance
These windows are engineered to Florida Building Code (FBC) High-Velocity Hurricane Zone (HVHZ) requirements. In practical terms, the product is designed, tested, and labeled for the stricter of Florida’s two wind-code regions, which is the one Miami sits inside of.

TAS 201 / 202 / 203 Testing Context
HVHZ-rated products are tested under the TAS protocol family. TAS 201 certifies large-missile impact resistance, TAS 202 certifies cyclic wind-pressure loading, and TAS 203 certifies forced-entry resistance. The Geometric & Shaped Windows we order from PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass are tested under this protocol family.

Design Pressure Matched to Your Wind Zone
We specify design pressure based on where in Miami the window is going. A unit on a sheltered interior courtyard wall doesn’t need the same rating as a second-story gable facing the Atlantic. Design pressures are matched to your wind zone, up to +/-100, and never higher than required.

Energy Performance
Low-E and insulated glass options are available on shaped configurations. This matters in Miami because glass area equals solar heat gain. A large west-facing radius window in Doral will perform very differently with Low-E insulated glass than with clear laminated alone. We help you pick the right glass for the exposure.

Color & Glass Options

The five finish options, White, Almond, Bronze, Black, and Tan, cover most of what we see across Miami architecture. White and Almond read classic on Mediterranean and Spanish Colonial homes in Coral Gables and Shenandoah. Bronze and Tan blend into earth-toned stucco and terra cotta details. Black frames have become the default on modern builds in Wynwood, Edgewater, and the Design District, where crisp contrast against white walls is the look. All five finishes are available on both aluminum and vinyl frames, depending on manufacturer and configuration.

Glass choice is about light, heat, and clarity. Clear laminated impact glass is the most economical path to hurricane protection and preserves the truest view. Tinted laminated glass cuts glare, which makes a difference on a large triangular unit facing the afternoon sun. Low-E insulated glass adds a thermal break and blocks a significant portion of solar heat, which pays off on shaped windows with big surface area. The shape is the statement; the glass decides how the room feels.

Installation by Winslow Windows & Doors in Miami

Improper installation compromises any NOA-rated system. A shaped window that isn’t set level, plumb, and square leaks, binds, and eventually fails, regardless of what the product was engineered to do. That’s why every Geometric & Shaped Window we sell in Miami is installed by our own team, using the same practices on every job.

We start with a pre-installation inspection and precise measurement of the rough opening. Then we verify the opening dimensions against the fabricated unit before it ever goes into production, because with custom shapes there is no “close enough.” During installation we set the window level, plumb, and square, following AAMA 2400/2410 installation practice and sealing the perimeter with AAMA 812 low-expansion foam. We then apply the manufacturer-specified exterior sealant system, conduct a final water test, and clean the site. Permits are part of the conversation from day one. Miami-Dade and most municipalities inside it require HVHZ-compliant product documentation before a permit is issued, and we prepare that submittal package for you. Coastal exposure, wind zone, and local permitting all shape how a project in Miami gets done, and we manage all three.

Frequently Asked Questions - Geometric & Shaped Windows

What wind zone or design pressure is the Geometric & Shaped Window rated for?
Design pressure is matched to the wind zone of your specific Miami property, up to +/-100, and never higher than what your opening requires. During quoting we confirm the exact design pressure your permit will demand, and we order the window to that rating. Call (863) 862-5435 and we’ll verify the requirement for your address.

What is the lead time on a Geometric & Shaped Window?
Lead time for custom-fabricated shapes typically runs longer than stock rectangular impact windows because each unit is made to order. The exact timeline depends on the manufacturer, configuration, glass package, and current production capacity. We confirm lead time at quote so you can plan your project accurately. Call (863) 862-5435 for a current estimate.

Does a Geometric & Shaped Window require a Miami-Dade NOA or Florida Product Approval submittal for my permit?
Yes. A permit for impact windows in Miami will require the applicable Miami-Dade NOA or Florida Product Approval documentation for your specific configuration. Winslow Windows & Doors pulls the correct submittal paperwork for every window we order, so your permit package matches your installations exactly.

Can I customize the size and configuration of the shape?
Yes, that’s the entire point of this product line. The window is custom-fabricated to your opening, in the shape you specify, with the frame material, finish, and glass package you choose. We measure first, we verify the dimensions before production, and we order the unit to fit what actually exists on your wall.

How do I maintain the frame and glass on a shaped impact window?
Maintain the frame with mild soap and water, and inspect the perimeter sealant once a year. Miami’s sun and salt air are hard on exterior finishes, so keep drainage channels clear of debris. Never pressure-wash directly at the glass-to-frame joint. A visual check after any major storm is good practice. If you notice cracked sealant or fogging between panes, call us at (863) 862-5435 and we’ll assess it.
