Geometric & Shaped Windows

Geometric & Shaped Windows in Palm Beach, FL | Winslow Windows & Doors

Geometric and shaped windows are how you get true architectural character into a Palm Beach home without gambling on storm protection. Triangles over a gable, a half-round over the front entry, a hexagon in a stairwell, and every one of them carrying laminated impact glass engineered for Florida’s wind zones. Winslow Windows & Doors fabricates these to order and installs them properly, because a window this unusual only works if the rough opening, the seal, and the anchoring are all done right. We’ve been doing exactly that for homeowners across Palm Beach, FL. If you’re planning a custom shape, call us at (561) 782-7525 and we’ll walk you through the options, the engineering, and the quote.

Product Overview - Geometric & Shaped Windows

Geometric and shaped windows are triangular, hexagonal, octagonal, trapezoid, and curved configurations built on the same hurricane-rated foundation as every other impact product we carry. They’re custom-fabricated to your opening, not picked from a stock list, which means each one is drawn, approved, and built for a specific wall in a specific house. That matters a lot in Palm Beach, FL, where a misplaced radius or a sloppy template means a frame that doesn’t seat, a seal that fails, and a very expensive hole in your wall.

What makes these shapes viable in hurricane-prone construction is the frame engineering. An octagon or a circle has multiple segments, each of which has to hold glass under wind pressure from every direction. The frame profiles we use, in aluminum and vinyl, are designed so each joint can be mechanically fastened and sealed, not just snapped together. The laminated glass itself does the heavy lifting during a storm. The PVB interlayer holds the glass in the frame even if it cracks under impact, which is the whole point of an impact system. You keep the architectural detail. You don’t lose the protection.

These windows show up most often in entryways, stairwells, gable ends, and transom positions. Palm Beach homes lean on Mediterranean and coastal styles where arched tops, circle windows, and angled glass are part of the visual vocabulary. Winslow Windows & Doors supplies and installs these across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, so you have real choices in frame profile, finish, and glass package without being locked into one manufacturer’s catalog. Call us at (561) 782-7525 to talk through what fits your elevation.

Technical Specifications

Here’s the spec sheet in plain terms. Every field below is matched to Florida wind-zone requirements and selected per opening, not per product family.

• Frame materials: Aluminum and vinyl. Aluminum is the go-to for large spans and slimmer sightlines. Vinyl works well for mid-size shapes and offers a different price point and thermal profile.
• Maximum size: Custom fabricated to order. There is no stock maximum. The engineering review on each configuration determines the outer limits for the specific shape, frame material, and design pressure required at your elevation.
• Glass options: Laminated impact glass with PVB interlayer, Low-E insulated glass, tinted glass, clear glass. Mix and match where the design calls for it.
• Finish options: White, almond, bronze, black, tan. Interior and exterior can be specified to match the rest of the fenestration.
• Sill and perimeter details: Matched to the frame profile and engineered for positive drainage, since Palm Beach’s rain season does not give you grace periods.
• Design pressure: Matched to your wind zone, up to +/-100, never higher. In other words, we engineer the window for what your specific opening actually requires. We don’t over-spec to inflate a number, and we don’t under-spec to hit a price.

Hurricane & Compliance Performance

Laminated Impact Glass
Each panel uses laminated glass with a PVB interlayer. When a projectile hits, the glass may crack, but the interlayer keeps the glass in the frame, so the window remains a barrier. This is the core of impact protection and it’s standard on our geometric and shaped window packages in Palm Beach, FL.

Miami-Dade NOA / Florida Product Approval
Approval numbers are issued per configuration, which is why we verify the specific NOA or Florida Product Approval on your quote. A shape that passes in one frame material isn’t automatically approved in another. You’ll see the numbers in writing before anything is ordered.

FBC / HVHZ Compliance
Every geometric and shaped window we sell in Palm Beach is engineered to Florida Building Code High-Velocity Hurricane Zone requirements. HVHZ is the stricter standard that governs Palm Beach County and Miami-Dade. We don’t carry anything that falls below it.

TAS 201 / 202 / 203 Testing Context
TAS 201 covers large-missile impact, TAS 202 covers cyclic wind-pressure loading, and TAS 203 covers forced-entry resistance. That’s the protocol family HVHZ-rated products are tested under. If a window hasn’t been through this gauntlet, it doesn’t belong in a Palm Beach opening.

Design Pressure for Your Wind Zone
Design pressures are matched to your wind zone, up to +/-100, and never higher. What that means for you: we look at the specific opening, the building geometry, and the exposure, then specify what actually satisfies code. Clean engineering, no padding.

Energy Performance
Low-E and insulated glass options are available on shaped configurations. If the window faces the afternoon Palm Beach sun, a Low-E insulated build cuts solar heat gain and makes the room more comfortable without changing the look of the frame.

Color & Glass Options

The finish you pick should do two things at once: anchor the window in the home’s palette and hold up under salt air and sun. Along the Palm Beach oceanfront, bronze and black frames read as modern and disappear against dark mullions. White and almond fit classic Mediterranean elevations, where contrast against stucco is the point. Tan works well on coastal transitional homes that are trying to keep everything soft. All five finishes, white, almond, bronze, black, and tan, are available on both aluminum and vinyl frames, and most homeowners specify interior and exterior separately so the room side can match the trim.

Glass choice matters almost as much as shape. Clear laminated impact glass is the purest look, and it’s what most of our clients choose when the view is the point. Tinted glass cuts glare and heat in west-facing gables and high stairwells. Low-E insulated glass is the pick for conditioned spaces where you’re trying to keep cooling bills sane during a Palm Beach summer without sacrificing the shape. A half-round over a door can stay clear. An octagon on a west wall probably should not. Our job is to help you pick the right combination for each opening, then prove it with the quote. Call (561) 782-7525 for specifics.

Installation by Winslow Windows & Doors in Palm Beach

Here’s the part that separates a window that performs for thirty years from one that becomes a water stain on a drywall ceiling. A shaped impact window is only as good as what’s around it. The NOA you get from the manufacturer assumes a correct installation. Cut corners on anchoring, shimming, or perimeter sealing, and you’ve got an approved product sitting in an unapproved opening.

Our process in Palm Beach starts with a pre-installation inspection. We measure the actual rough opening, check the substrate, verify the wind zone at the specific elevation, and document everything. Then we set the frame level, plumb, and square. That’s not optional language. A frame that’s racked or twisted won’t seat the sash properly, and on a geometric profile, a tiny misalignment at the joint becomes a visible gap at the glass. We flash the opening, anchor per the approved method for that frame material, and seal the perimeter with AAMA 812 low-expansion foam sealant. The foam does two jobs: it seals air and water, and it takes up the dimensional movement of the frame without stress on the sealant joint.

Installation practice follows AAMA 2400 and 2410 standards throughout. We do a final water test on every shaped opening we install in Palm Beach, FL, because shaped windows create more seal paths than a rectangle and each one is a potential entry point. Then we clean the glass, walk the opening with you, and leave the site better than we found it. Permitting awareness is part of the service. Palm Beach County and its municipalities are HVHZ jurisdictions, and your permit package has to include the right product approval submittals. We provide what’s needed so the approval numbers on your quote match the approval numbers on the permit.

Frequently Asked Questions - Geometric & Shaped Windows

What wind zone / design pressure are Geometric & Shaped Windows rated for?
Design pressures are matched to your wind zone, up to +/-100. We engineer each opening individually, so the DP we quote for your gable window in Palm Beach is exactly what that opening requires under FBC-HVHZ. Nothing higher, nothing lower. Call (561) 782-7525 for an exact figure on your project.

What is the lead time on a custom Geometric & Shaped Window?
Because every shape is custom-fabricated to your template, lead times typically run several weeks from approval drawings to delivery. The template and the approval process add time you don’t see on stock rectangle orders. If you’re working around a renovation schedule, call us early so the window doesn’t hold up the framing.

Does it require a Miami-Dade NOA or Florida Product Approval submittal for my permit?
Yes. In Palm Beach County, your permit package must show that the specific geometric or shaped configuration carries the appropriate NOA or Florida Product Approval. We provide the submittal documents for your exact quote. A generic product approval won’t cover a configuration it wasn’t tested in.

Can I customize the size or configuration?
Every geometric and shaped window we sell is custom fabricated to your opening. You’re not limited to catalog sizes. The engineering review sets the outer bounds for each shape, frame material, and glass package, and we’ll confirm feasibility at the quote stage. If you’ve drawn something unusual, call (561) 782-7525 and we’ll tell you what’s possible.

How do I maintain the frame?
Rinse the frame and glass with fresh water every few months, especially if you’re near the ocean in Palm Beach. Don’t use abrasive pads or strong solvents on the finish. Check the perimeter sealant annually and after any major storm. If you see a gap or cracking at a joint, call us before it becomes a leak.

Will the price change once work starts?
No. We quote fixed pricing on the exact configuration, glass package, and finish we specify. The only way the number changes is if you change the scope after the quote. You’ll see everything in writing before anything is ordered, and estimates are free. Call (561) 782-7525 to start one.
