Geometric & Shaped Windows

Geometric & Shaped Windows in Coral Gables, FL | TruePane Windows & Doors

We’re talking triangles, hexagons, octagons, arches, and custom curves, all fabricated to your exact opening with laminated impact glass. TruePane Windows & Doors has installed these across PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines throughout Coral Gables, so we know what the building department expects and what the wind actually does to a non-square opening.

Product Overview - Geometric & Shaped Windows

A shaped window is not a standard rectangle with a personality. It’s a structural opening with multiple bearing points, custom angles, and a glazing package that has to survive the same wind event as everything else on the wall. In Coral Gables, where Mediterranean Revival and Spanish Colonial homes lean heavily on arched and circle-top details, these windows carry a lot of the street-facing character. They’re also common in contemporary builds where a fixed triangle or trapezoid fills a gable or a stairwell wall.

What we sell and install are impact-rated geometric configurations built to order. The frame, whether aluminum or vinyl, is engineered around your specific rough opening dimensions, not cut down from a stock unit. The glass is laminated impact with a PVB interlayer, so under a large-missile strike the glass cracks but stays in the frame instead of blowing into your living room. Custom fabrication means the design pressure rating is calculated for your exact shape and size, matched to your Coral Gables wind zone. You get the architectural detail without giving up the protection a Florida coastal home actually needs.

Technical Specifications

Every geometric window we sell is made to your opening. Nothing about this product comes off a shelf. Here’s how the specs break down:

• Frame materials: Aluminum or vinyl, selected for the shape and the exposure of the wall it’s going into
• Maximum size: Custom fabricated to order, so the practical limit is what your structural engineer and the product approval allow for your configuration
• Glass options: Laminated impact glass with PVB interlayer, Low-E insulated glass, tinted glass, or clear glass
• Finish options: White, almond, bronze, black, and tan
• Design pressure: Matched to your wind zone, up to +/-100, never higher
• Compliance documentation: Miami-Dade NOA and Florida Product Approval numbers available per configuration

Because these are custom-fabricated, the exact performance values live on your specific quote, not in a generic brochure. We’ll pull the right NOA for your shape and size before you sign anything.

Hurricane & Compliance Performance

Laminated Impact Glass
This is the core of the system. The PVB interlayer is what holds the glass in the frame when a projectile hits it. The outer lite may shatter, but the window stays intact, keeping wind, rain, and debris on the outside where they belong. It’s the same impact technology we use across our full Coral Gables product range.

Miami-Dade NOA / Florida Product Approval
Each geometric configuration carries its own Notice of Acceptance or Florida Product Approval number. These are issued per size and shape, not as a blanket rating. We verify the exact approval document for your specific window on your quote, so your permit submittal in Coral Gables goes through without a fight.

FBC / HVHZ Compliance
Every geometric window we install in Coral Gables is engineered to Florida Building Code High-Velocity Hurricane Zone requirements. HVHZ is the strictest wind standard in the state, and Coral Gables sits squarely inside it. The frame, glass package, and anchoring are all designed to that bar.

TAS 201 / TAS 202 / TAS 203 Testing Context
These are the test protocols behind HVHZ product approvals. TAS 201 covers large-missile impact, TAS 202 covers cyclic wind-pressure loading, and TAS 203 covers forced-entry resistance. The geometric windows we install are tested to this protocol family, which is what gives the NOA its weight.

Design Pressure for Your Wind Zone
Design pressure is matched to the wind zone of the specific wall elevation on your Coral Gables property. Ratings go up to +/-100, and we never push a unit past what its approval actually says. An honest DP rating matters more than a big number on a marketing sheet.

Energy Performance
Low-E insulated glass options are available for shaped windows, which matters in a climate like Coral Gables where afternoon sun hits east- and west-facing walls hard. Tinted glass is also an option for glare control without losing the architectural look.

Color & Glass Options

The finish you pick changes how the window reads from the street. White and almond stay classic on Coral Gables Mediterranean homes, especially with stucco or coral stone walls. Bronze and black give a sharper, more contemporary line, which works well on modern builds and on homes where the window frames are meant to recede against darker trim or shadow lines. Tan splits the difference, blending with warmer exterior palettes without disappearing entirely.

On the glass side, clear laminated impact is the default for maximum light and an unobstructed view, which matters a lot if your geometric window is a fixed picture unit framing a tree line or courtyard. Low-E insulated glass trades a slight tint for better thermal performance, and it’s worth considering for any geometric window facing west in Coral Gables. Tinted glass is a practical choice for stairwells and gable windows where the sun angles in for hours at a time. We’ll walk you through the trade-offs at your estimate.

Installation by TruePane Windows & Doors in Coral Gables

A geometric impact window is only as good as the opening it’s set into. The NOA rating assumes a proper installation: the frame anchored correctly, the perimeter sealed, the load path intact. Cut corners on the install and you’ve bought an expensive piece of glass that won’t perform when it counts. That’s the reason we install these ourselves, with our own crew, on every job in Coral Gables.

Our process starts with a pre-install inspection of the rough opening. Shaped openings are rarely square, so we measure every point and check the structural surround before we order the window. The unit gets fabricated to those actual dimensions. On install day, we set the frame level, plumb, and square, shimming as needed so the reveal is even and the operation is correct. The perimeter gets AAMA 812 low-expansion foam sealant, which fills gaps without distorting the frame, and the install follows AAMA 2400/2410 practice for flashing and integration with the weather barrier. Then we run a water test before we call the job done.

Coral Gables adds its own wrinkles. Coastal exposure means salt air, so flashing and sealant details matter more here than inland. The permitting office expects your HVHZ product approval documentation to be in order before they’ll sign off. We know what they’re looking for, and we’ll have the NOA and Florida Product Approval numbers ready for your permit submittal. Don’t let a handyman or a general-purpose contractor set a shaped impact window here. The risk is too high and the fix is too expensive.

Frequently Asked Questions - Geometric & Shaped Windows

What wind zone and design pressure is the Geometric & Shaped Windows product rated for?
Design pressure is matched to the wind zone of your specific Coral Gables property and wall elevation, up to +/-100. There is no single DP number for a shaped window because the rating changes with the size, shape, and frame configuration. We’ll pull the exact approved rating for your unit when we quote it.

What is the lead time for a custom geometric window?
Because these are fabricated to your opening rather than pulled from inventory, lead times run longer than a stock rectangle. The range depends on the manufacturer, the shape, and the glass package. We’ll give you a firm production window when you place the order, and we’ll coordinate the install around it so you’re not living with a boarded-up opening.

Does my Coral Gables permit submittal require a Miami-Dade NOA or Florida Product Approval document?
Yes. Coral Gables sits in the High-Velocity Hurricane Zone, and the building department will want to see the approval document for the exact window you’re installing, not a similar one. TruePane Windows & Doors includes the correct NOA or Florida Product Approval package with your quote, so the submittal is ready for your permit application.

Can I customize the size or configuration of my geometric window?
That’s the entire point of this product. Triangle, hexagon, octagon, true arch, eyebrow curve, or anything your architect drew. The window is fabricated to your opening dimensions, and the glazing and finish are chosen to match your existing windows in Coral Gables. We’ll confirm what’s achievable within the product approval limits for your shape.

How do I maintain the frame and glass on a shaped window?
Wash the glass with a mild soap solution and a soft cloth, and wipe down the frame and track with a dry cloth to keep salt residue from sitting on the finish. Check the perimeter sealant once a year, especially after storm season. If you see gaps or cracks, call us at (954) 507-3613 before the next big blow, and we’ll re-seal it properly. An estimate is free.
