AfterBay & Bow Windows in Palm Beach, FL | Winslow Windows & Doors
Bay and bow windows are the architectural move that turns a flat wall into a light-filled projection with real, usable interior space. In Palm Beach, FL, where homes lean on coastal views and wide sightlines, these multi-panel configurations do two jobs at once: they open the room to the outdoors and they hold up to hurricane-force wind when built as laminated impact systems. Winslow Windows & Doors fabricates and installs custom bay and bow units across PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, engineered to your specific wind zone and installed to HVHZ standards.

Product Overview - Bay & Bow Windows
A bay window typically combines a fixed center picture unit with two angled side vents, creating a three-panel projection that adds a window seat, a plant shelf, or a reading nook. A bow window uses four or more panels set in a gentle arc, producing a softer curve and a wider panoramic sweep. Both configurations extend beyond the exterior wall line, which is exactly why they’re so prized in Palm Beach homes, both the 1920s Mediterranean Revival houses along the lakefront and the newer coastal contemporary builds west of I-95.
For hurricane-prone construction, the projection itself is the engineering challenge. Every joint, mullion, and glass lite has to work as one structural unit when wind pressure hits from multiple angles. That’s why our bay and bow windows are custom fabricated to the opening, never pieced together from stock sizes. The frames are aluminum or vinyl, the glass is laminated impact with a PVB interlayer, and the entire assembly is engineered to stay intact under the design pressures your wind zone demands. You get the added interior square footage and panoramic sightlines of a projecting window, without sacrificing the protection a Palm Beach home requires.
Technical Specifications
Every bay and bow unit we fabricate in Palm Beach starts with the same baseline: the opening dictates the build. Here’s what goes into each configuration.
- Frame materials: Aluminum or vinyl, selected for the exposure and architectural style of the home.
- Maximum size: Custom fabricated to the opening. There’s no stock cap, the engineering determines the limit.
- Glass options: Laminated impact glass (PVB interlayer), Low-E insulated glass, tinted glass, clear glass.
- Finish options: White, almond, bronze, black, and tan.
- Sill options: Standard sill or seat/shelf sill, depending on whether you want the projection to function as built-in seating or display space.
- 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, engineered to Florida Building Code High-Velocity Hurricane Zone requirements.
We configure every unit against the specific opening, exposure, and wind zone of the home. No two Palm Beach installations are identical, and a bay window that works on a sheltered interior lot in El Cid may need a different mullion package than one facing the ocean in Ocean Ridge.
Hurricane & Compliance Performance
Bay and bow windows in coastal Florida carry more engineering responsibility than almost any other window profile. Here’s what’s built into every unit we install in the Palm Beach area.
Laminated Impact Glass
Laminated Impact Glass. The core of the system is laminated impact glass with a PVB (polyvinyl butyral) interlayer. When impacted, the glass may crack but the interlayer holds the glass in the frame, keeping the building envelope sealed and preventing wind-driven debris from breaching the interior.
Miami-Dade NOA / FL Product Approval
Miami-Dade NOA / Florida Product Approval. Each bay or bow configuration carries its own Miami-Dade NOA (Notice of Acceptance) and Florida Product Approval numbers, issued per configuration. We verify the exact approval numbers on your specific quote before fabrication begins.
FBC / HVHZ Compliance
Engineered to FBC HVHZ requirements. Every unit is engineered to Florida Building Code High-Velocity Hurricane Zone requirements. That’s the governing standard for Palm Beach County, and it means the assembly, anchoring, and glazing are designed for sustained hurricane loading, not just a passing storm.
TAS 201/202/203 Testing Context
TAS Protocol Testing. The product family is tested under TAS 201 (large-missile impact), TAS 202 (cyclic wind-pressure loading), and TAS 203 (forced-entry resistance). These are the protocols HVHZ-rated products are measured against, and they’re the reason the glass and frame behave as one unit under stress.
Design Pressure for Your Wind Zone
Design pressure matched to wind zone. We match design pressure to your wind zone, up to +/-100, never higher. That upper bound is deliberate. Overbuilding beyond what the zone requires adds cost without adding meaningful protection, and we’d rather put your budget into the right glass package.
Energy Performance
Low-E / insulated glass options. Low-E and insulated glass options are available for energy performance, which matters in Palm Beach where afternoon sun on a west-facing bay window can drive cooling costs up. The right Low-E coating cuts solar heat gain without reducing visible light.
Color & Glass Options
The finish you choose should do what Palm Beach architecture asks of it. White and almond are the classic choices for Spanish Mediterranean and Florida Vernacular homes, where bright trim against stucco or coral stone is the expected look. Bronze and black have become the default on modern coastal builds, especially where the window frames are meant to disappear against the glass at dusk. Tan splits the difference nicely on homes with natural stone or wood accents.
Glass selection depends on what the window faces. Clear laminated impact glass works well on north and east elevations where light is soft and heat gain is manageable. Tinted glass handles the brutal west-facing exposure, cutting glare and solar heat without changing the aesthetic too dramatically. Low-E insulated glass is the right pick when the bay window covers a large wall area and cooling costs are a concern. Every option is available in laminated impact construction, so the protection question never changes, only the daylight and heat profile do.
Installation by Winslow Windows & Doors in Palm Beach
Installation is where bay and bow windows either perform or fail. The projection means the entire assembly cantilevers off the wall line. If the rough opening isn’t square, if the mullions aren’t shimmed right, if the perimeter seal isn’t continuous, the NOA-rated system won’t behave the way it was tested. That’s why we treat installation as part of the engineering, not a separate trade.
Every Palm Beach installation starts with a pre-install inspection of the opening, the header, and the surrounding wall assembly. We set the unit level, plumb, and square, using the anchoring patterns specified in the approved drawings. The perimeter gets an AAMA 812 low-expansion foam sealant, applied in a continuous bead to prevent air and water intrusion. Our installation practice follows AAMA 2400/2410 standards. After the unit is set and sealed, we run a water test on the perimeter, then handle the trim, interior sill, and final walkthrough.
Palm Beach County sits inside an HVHZ jurisdiction, which means permits and inspections are part of the process. We’re familiar with the submittal requirements in Palm Beach, West Palm Beach, Lake Worth Beach, and the smaller coastal municipalities. If your bay or bow window needs a Miami-Dade NOA or Florida Product Approval number on the permit paperwork, we provide it with the quote. Improper installation compromises the NOA-rated system, and in a coastal wind zone, that’s not a risk worth taking.
Frequently Asked Questions - Bay & Bow Windows
The design pressure is matched to your specific wind zone, up to +/-100, never higher. Palm Beach homes in exposed coastal locations typically require a higher design pressure than homes further inland, and we engineer each unit to the zone, not to a generic number. Call (561) 782-7525 for an exact specification on your home.
Lead time depends on the configuration, the glass package, and the manufacturer line you select. Custom bay and bow units are fabricated to the opening, so production runs longer than a stock window order. We’ll give you a written timeline with your quote, and we keep you updated through fabrication and delivery. Call (561) 782-7525 to start the process.
Yes. Bay and bow windows in Palm Beach County require permit submittal documentation, and each configuration carries its own Miami-Dade NOA and Florida Product Approval numbers. We provide the correct approval documentation for your specific build with the quote, ready for your permit application. Call (561) 782-7525 and we’ll walk you through what your municipality needs.
Yes. Every bay and bow unit we fabricate is custom built to the opening. You can adjust the number of panels, the projection depth, the vent placement (which side panels open and which are fixed), and the sill style. The only constraint is engineering: the configuration has to meet the design pressure your wind zone requires. Call (561) 782-7525 to discuss what’s possible for your wall.
Aluminum and vinyl frames need minimal maintenance. Rinse the frames with fresh water periodically, especially in coastal Palm Beach where salt spray builds up, and keep the weep holes clear so drainage works as designed. Inspect the perimeter sealant annually. If you see cracking or separation, call us before water has a chance to get behind the frame. Call (561) 782-7525 if you ever have a question about your installation.
