Bay & Bow Windows in Boca Raton, FL | Winslow Windows & Doors
Bay and bow windows change how a room feels. They push the glass outward past the wall line, add a wide shelf or seat inside, and wrap the view around you in a way flat windows can’t. In Boca Raton, where daylight is strong and homeowners want interiors that feel open, these windows do two jobs at once: they make the living room or breakfast nook bigger and they frame the view. Winslow Windows & Doors installs impact-rated bay and bow configurations with laminated glass engineered to your wind zone. Call (561) 816-5648 to talk through a project or schedule a free in-home measurement.
Product Overview - Bay & Bow Windows
A bay window typically uses three panels: a wide fixed center pane and two angled side panes, usually operating casements or double hungs. A bow window uses four, five, or six panels arranged in a gentle arc. Both configurations project a foot to two feet beyond the wall, which creates interior square footage you don’t have to build with framing. We build ours as projecting multi-panel configurations in laminated impact glass, with panoramic sightlines engineered to your wind zone.
Why does that matter in South Florida? Because a window that sticks out from the house catches wind differently than a flush-mounted unit. The projection creates uplift and pressure loads that a standard window never sees. A bay or bow window built for Boca Raton has to be fabricated with a reinforced seat board, structural mulling, and glass that holds under impact. That’s the product we sell: not a decorative add-on, but an engineered window assembly rated for High-Velocity Hurricane Zone construction.
We spec these in aluminum and vinyl frames across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines. Each project is custom fabricated to the opening. The homeowner picks the configuration, the panel count, the operating style, the glass package, and the finish. We handle the engineering, the permitting documentation, and the installation.
Technical Specifications
- Frame materials: Aluminum or vinyl, selected for the exposure and architectural style of the home
- Maximum size: Custom fabricated to the opening - no stock bay or bow kits

Every bay and bow configuration is project-specific. The panel widths, projection depth, mulling details, and design pressure rating all depend on the opening, the home’s exposure category, and the wind zone where the house sits in Boca Raton.
Hurricane & Compliance Performance
Laminated Impact Glass
The glass package uses a PVB (polyvinyl butyral) interlayer bonded between two panes. Under impact, the glass may crack, but the interlayer holds the pieces in the frame. That keeps wind, rain, and debris outside the house, which is the point of an impact window in a hurricane zone like Boca Raton.
Miami-Dade NOA / Florida Product Approval
Each bay and bow configuration carries Miami-Dade NOA (Notice of Acceptance) and Florida Product Approval numbers. These are issued per specific configuration, so the exact approval number depends on the size, glass package, and frame combination you select. We provide the documentation with your quote and verify it on your permit submittal.
FBC / HVHZ Compliance
The product is engineered to Florida Building Code High-Velocity Hurricane Zone requirements. HVHZ is the stricter code that applies to Broward and Miami-Dade counties, and many Boca Raton projects reference HVHZ standards even though Palm Beach County has its own wind provisions. We build to the stricter requirement.
TAS 201 / 202 / 203 Testing Context
HVHZ-rated products are tested under a specific protocol family. TAS 201 covers large-missile impact, TAS 202 covers cyclic wind-pressure loading, and TAS 203 covers forced-entry resistance. This is the testing context these windows are engineered within, and the approvals reference these test standards.
Design Pressure for Your Wind Zone
Design pressure, or DP, is a PSF rating that tells you how much wind load the window can take before failure. We match design pressures to your wind zone, up to +/-100, never higher. A higher number isn’t better here; the right number is the one that fits your home’s actual exposure. We calculate that per opening.
Energy Performance
Low-E and insulated glass options are available for these configurations. Low-E coatings cut solar heat gain, which matters in Boca Raton where east and west exposures take direct sun most of the year. We’ll walk through the glass package choices based on which direction the bay or bow faces and how much daylight you want inside.
Color & Glass Options
Most Boca Raton homes fall into two camps: coastal modern or Mediterranean. For coastal modern, white and black frames read clean against stucco and glass railings. For Mediterranean style homes with barrel tile roofs and warm exterior tones, almond, bronze, and tan frames blend better than stark white. We order all five finishes: white, almond, bronze, black, and tan.
Glass choice depends on what the room is for. Laminated impact glass is the standard starting point for any bay or bow in Palm Beach County. Add Low-E insulated glass when the window faces west and the room heats up in the afternoon. Tinted glass helps with glare in rooms where you watch TV or work. Clear glass keeps the view from a beachfront or golf course property completely unobstructed. We’ll help you pick the right combination when we measure the opening.
Installation by Winslow Windows & Doors in Boca Raton
A bay or bow window is only as good as the crew that hangs it. The projection means the entire assembly carries weight differently than a flush window, and in a hurricane zone, the fastening pattern and sealant details are not optional extras. We install to AAMA 2400/2410 practice, which is the industry standard for installation of windows in exterior walls, and we use AAMA 812 low-expansion foam for the perimeter seal.
Our process starts with a pre-install inspection. We check the rough opening, the header condition, and the seat board structure before we order anything. On install day, we set the unit level, plumb, and square, shim the seat board properly, and fasten to the structure per the NOA details for that configuration. Then we foam the perimeter, flash and seal the exterior, and run a water test on the sill and mull joints. When the job is done, the area is cleaned and the old window is hauled away.
Boca Raton brings its own considerations: coastal exposure in neighborhoods east of Dixie Highway, higher wind zones in areas by the Intracoastal, and permitting requirements that vary by project. We’ve pulled permits in this city long enough to know what the building department looks for. An improper install compromises the entire NOA-rated system, which is exactly why this is not a handyman job. The approval means nothing if the window isn’t fastened the way the engineering documents say to fasten it.
Frequently Asked Questions - Bay & Bow Windows
Design pressure is matched to your specific wind zone, up to +/-100, never higher. The exact rating for your home depends on the location of the opening, the height of the building, and the exposure category for your Boca Raton neighborhood. We calculate this per project and show you the number on your quote. Call (561) 816-5648 if you want us to run the numbers on a specific opening.
Most bay and bow configurations take four to eight weeks from approved drawings to delivery, depending on the manufacturer line you select. Since every unit is custom fabricated to the opening, nothing ships from stock. We give you a realistic delivery window when you place the order and keep you updated as the date firms up.
Yes. Boca Raton’s building department requires product approval documentation with your permit application for any impact-rated window. We provide the NOA and Florida Product Approval numbers for your specific configuration as part of the permit package. The approval number changes with the size and glass package, so it’s tied to your exact order.
Every bay and bow window we sell is custom fabricated. You pick the panel count, the operating style of the side panels, the projection depth, the glass package, the frame material, and the finish. There is no standard size chart because no two openings are alike. We measure first, then draw it, then build it.
Rinse the frame and tracks with fresh water every few months, especially if you live near the ocean in Boca Raton where salt sits on surfaces. Wipe the glass with a mild soap and water solution. Check the weep holes in the sill to make sure they drain. Keep the perimeter caulking intact and re-seal when it shows age. The frame material itself doesn’t need painting or refinishing.
