Product Overview - Geometric & Shaped Windows

Standard rectangular windows leave creative architects and discerning homeowners in Hobe Sound searching for something more distinctive. Geometric and shaped windows answer that need with triangular, hexagonal, octagonal, and curved impact-glass configurations, custom-fabricated to your opening - architectural detail without sacrificing wind-zone protection.

These aren’t decorative afterthoughts bolted onto a standard frame. Each configuration starts from your rough opening dimensions and is engineered as a complete system: frame, glazing, and anchorage calculated together. The aluminum and vinyl frame options we carry through our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines are extruded and reinforced to handle the asymmetric loads that shaped openings create. A triangle under wind pressure behaves differently than a rectangle. The geometry concentrates stress at the corners and along shorter spans. Our suppliers account for this in their NOA-submitted designs, and we verify it during installation.

In Hobe Sound, these windows appear in gable-end accents, stairwell landings, master suite transoms, and pool-cabana feature walls. The curved profiles work particularly well in Mediterranean and coastal contemporary homes common along the Treasure Coast. Whether you’re matching an existing architectural vocabulary or defining a new one, the shaped profile lets light enter from angles fixed windows can’t achieve, while the laminated impact glass keeps that opening from becoming a vulnerability when a storm approaches.

Hurricane & Compliance Performance

Laminated Impact Glass
The PVB (polyvinyl butyral) interlayer holds glass fragments in the frame even after direct impact. If the outer lite breaks, the inner lite and interlayer maintain the pressure envelope. This is what separates hurricane-rated glazing from standard tempered glass that shatters into falling pieces.

Miami-Dade NOA / Florida Product Approval
Every geometric configuration we quote carries its own Notice of Acceptance or Florida Product Approval number. These aren’t blanket certifications. The NOA specifies the exact frame profile, glazing make-up, anchorage pattern, and maximum size for that approval. We list the relevant numbers on your quote for permit submittal.

FBC / HVHZ Compliance
Engineered to Florida Building Code High-Velocity Hurricane Zone requirements. Hobe Sound sits in a region where HVHZ standards apply, meaning products must demonstrate performance beyond what standard coastal codes demand. The shaped windows we install meet these elevated criteria.

TAS 201 / 202 / 203 Testing Context
The protocol family for HVHZ-rated products: TAS 201 (large-missile impact), TAS 202 (cyclic wind-pressure loading), and TAS 203 (forced-entry resistance). These test methods subject the complete window assembly to impacts from lumber missiles, thousands of pressure cycles, and attempted breach. Passing all three is mandatory for HVHZ approval.

Design Pressure for Your Wind Zone
Design pressures matched to your wind zone, up to +/-100 PSF - never higher. We calculate the required rating from your specific address, structure height, exposure category, and surrounding topography. An inland Hobe Sound ranch home and a Jupiter Island waterfront estate face different demands. We size accordingly.

Energy Performance
Low-E insulated glass options manage solar heat gain and winter heat loss without compromising impact performance. The low-emissivity coating reflects infrared radiation while passing visible light. In Hobe Sound’s climate, this matters for west-facing gables and south-facing accent windows that receive intense afternoon exposure.

Color & Glass Options

The five standard finishes we offer through our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines cover the architectural palettes common in Hobe Sound and throughout Martin County.

White remains the default for Florida coastal homes, reflecting heat and blending with light stucco exteriors. Almond softens the contrast on cream or beige facades without the maintenance of painted wood. Bronze and Black have gained ground in contemporary and transitional designs, particularly on homes with dark standing-seam metal roofs or charcoal Hardie paneling. Tan bridges Mediterranean tile roofs and warmer stone veneers.

Glass selection depends on placement and priority. The laminated impact glass with PVB interlayer is non-negotiable for HVHZ compliance and forms the base specification. From there, we layer in performance: Low-E insulated for thermal control in conditioned spaces, tinted for glare reduction on entertainment walls and art niches, and clear where the design intent is pure, unobstructed light transmission. In Hobe Sound’s sun-drenched environment, most homeowners opt for Low-E on south and west orientations, clear on north-facing accents where heat gain is minimal.

Installation by Sightline Windows & Doors Hobe Sound in Hobe Sound

A Miami-Dade NOA-rated window becomes ordinary the moment it’s installed out of square, anchored to rotted framing, or sealed with the wrong perimeter foam. We’ve seen it: a perfectly engineered geometric unit, custom-fabricated to precise dimensions, underperforming because the rough opening wasn’t plumbed or the anchorage pattern was improvised. In Hobe Sound’s coastal exposure, with salt air accelerating corrosion at any breach, installation quality isn’t cosmetic. It’s structural.

Our process begins with a pre-install inspection of the rough opening. We check for level, plumb, and square; verify the framing is continuous and properly flashed; and confirm the anchor substrate matches the NOA-submitted detail. Geometric openings are particularly unforgiving - a raked triangle or curved top rail won’t hide a twisted rough opening the way a rectangular double-hung might.

We set each unit level, plumb, and square, then anchor per the manufacturer’s NOA-approved pattern. The perimeter receives AAMA 812 low-expansion foam sealant, which fills irregular gaps without distorting the frame as it cures. This matches AAMA 2400/2410 installation practice standards. We complete with a final water test, checking weep paths and seal continuity, then clean the site and protect the glass during remaining construction.

Hobe Sound’s location in Martin County means permit submittals require Florida Product Approval or Miami-Dade NOA documentation, wind-borne debris compliance statements, and often energy code forms. We provide the product approvals; your contractor of record handles the permit application. If we’re acting as the contractor, we manage that submittal directly. Either way, the documentation travels with the product from our quote through final inspection.

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 - never higher than your structure requires. We calculate the exact rating from your Hobe Sound address, building height, and exposure. Call (772) 362-5967 for a site-specific assessment and exact specification.

What is the lead time?
Lead times vary by manufacturer line and current production queue, typically ranging from several weeks to a few months for custom-fabricated geometric configurations. Shaped windows require individual engineering and production scheduling that standard rectangles don’t. We confirm current lead times on your written quote so you can coordinate with your construction schedule.

Does it require a Miami-Dade NOA or Florida Product Approval submittal for my permit?
Yes. Hobe Sound falls under Florida Building Code High-Velocity Hurricane Zone requirements, and Martin County building officials require Miami-Dade NOA or Florida Product Approval documentation for every impact-rated window. We provide the specific approval numbers for your quoted configuration with your submittal package. Call (772) 362-5967 to start the documentation process.

Can I customize the size or configuration?
Every geometric and shaped window we sell is custom fabricated to order from your verified field measurements. Triangular, hexagonal, octagonal, and curved profiles are all available in dimensions specific to your opening, subject to the maximum spans approved in the manufacturer’s NOA for that profile. We measure twice and verify with the factory before production begins.

How do I maintain the frame?
Rinse aluminum and vinyl frames quarterly with fresh water to remove salt accumulation, particularly on east and southeast exposures in Hobe Sound’s coastal environment. Clean tracks and weep holes annually to ensure drainage. Avoid abrasive cleaners or pressure washers directed at sealant joints. The finish is permanent on vinyl and baked powder-coat on aluminum; no repainting or resealing of the frame surface is needed under normal conditions.
