AfterBay & Bow Windows in Westchester, FL | Winslow Windows & Doors
Bay and bow windows extend your living space outward, adding a projecting glass alcove that captures panoramic sightlines and usable interior square footage. In Westchester, FL, where hurricane wind loads shape every building decision, these aren’t decorative afterthoughts - they’re engineered structural assemblies built from laminated impact glass and reinforced multi-panel framing. Winslow Windows & Doors fabricates and installs impact-rated bay and bow configurations across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, matched to your specific wind zone. Call (863) 251-5864 to discuss your opening and schedule a free measurement.
Product Overview - Bay & Bow Windows
Bay windows typically combine three panels - a wide center picture unit flanked by two angled operable or fixed units - while bow windows use four or more panels arranged in a gentler radius. Both profiles project outward from the wall plane, creating a deep sill shelf, a wider visual field, and a few extra square feet of floor space that reads as intentional living area rather than wasted corner.
For Westchester homes, the appeal goes beyond architecture. These assemblies face full exposure to wind-driven rain and flying debris during named storms. The version we sell and install is not a standard residential bay assembled from ordinary annealed glass. It’s fabricated as an impact-rated system: laminated glass with a PVB interlayer set into aluminum or vinyl framing engineered to carry the loads your wind zone demands. The result is a projecting window that adds light and dimension without compromising the building envelope.
Where bay and bow windows fit best depends on the elevation. We’ve installed them as front-facing living room focal points in Westchester ranch homes, as breakfast nook replacements in 1980s and 1990s builds, and as reading corners in bedrooms where the added projection creates a comfortable seating ledge. The configurations are fully custom - we fabricate to the opening, not from a limited size chart.
Technical Specifications
- Frame materials: Aluminum or vinyl, selected for coastal corrosion resistance and structural rigidity.
- Maximum size: Custom fabricated to the opening - no stock-size limitations.
- Glass options: Laminated impact glass (PVB interlayer), Low-E insulated glass, tinted glass, clear glass.
- Finish options: White, Almond, Bronze, Black, Tan.
- Sill options: Standard sill or seat/shelf sill for interior seating depth.
- Design pressure: Matched to your wind zone, up to +/-100 PSF - never higher.
- Compliance documentation: Miami-Dade NOA and Florida Product Approval numbers available per configuration; engineered to Florida Building Code (FBC) High-Velocity Hurricane Zone (HVHZ) requirements.
Because every bay or bow assembly is custom fabricated, the exact configuration - panel widths, angles, operator placement, and sill style - is determined during the site measurement. What doesn’t change is the glass package: every unit we sell carries laminated impact glass as the base spec.
Hurricane & Compliance Performance
These six features define how the Bay & Bow Windows line performs under Florida wind and impact conditions:
Laminated Impact Glass
The glass package uses a PVB (polyvinyl butyral) interlayer sandwiched between panes. Under impact, the glass may crack but the interlayer holds the shards in the frame, preventing wind and water intrusion through the breach. This is the same protective principle applied across all our impact window lines in Westchester.
Miami-Dade NOA / Florida Product Approval
Each bay and bow configuration carries its own Miami-Dade NOA (Notice of Acceptance) and Florida Product Approval numbers, issued per configuration - not as a blanket product-wide rating. We provide the specific approval documentation for your exact unit on your quote, which your Westchester permit application will reference.
FBC / HVHZ Compliance
The assemblies are engineered to Florida Building Code (FBC) High-Velocity Hurricane Zone (HVHZ) requirements. HVHZ governs the strictest wind-design and impact-protection provisions in the state code, and it applies directly to Westchester permitting.
TAS 201 / TAS 202 / TAS 203 Testing Context
HVHZ-rated products are tested under the TAS protocol family: TAS 201 (large-missile impact), TAS 202 (cyclic wind-pressure loading), and TAS 203 (forced-entry resistance). These three standards establish that a product can take a strike, endure repeated pressure cycling, and resist post-impact intrusion.
Design Pressure for Your Wind Zone
Design pressure is a PSF (pounds per square foot) rating, not a wind-speed number. We engineer each bay or bow window to the design pressure your Westchester wind zone requires, up to +/-100 PSF - never higher, because over-engineering beyond your zone buys nothing and under-engineering fails the permit review.
Energy Performance
Low-E and insulated glass options are available for these profiles. A Low-E coating on laminated impact glass reduces solar heat gain through those large projecting glass areas, which matters in a South Florida afternoon exposure. Tinted glass offers another layer of glare and heat management without changing the frame profile.
Color & Glass Options
The five finish options - White, Almond, Bronze, Black, and Tan - cover most Westchester architectural palettes. White and Almond suit the older Florida ranch and Mediterranean revival homes that dominate the neighborhood. Bronze and Black read more contemporary and work well on 2000s-era builds or homes with darker trim accents. Tan bridges the gap, matching beige and cream stucco elevations common throughout Westchester.
Glass selection follows the room’s orientation. Clear laminated impact glass maximizes visible light transmission, which works for north-facing rooms or shaded elevations. Low-E insulated glass is the practical choice for west-facing bay windows that catch hours of afternoon sun - the coating cuts solar gain while the insulated airspace improves comfort against the frame. Tinted glass reduces glare without relying on window treatments, which suits media rooms and seating alcoves. Every glass option carries the impact-rated PVB interlayer as the base construction, so choosing Low-E or tinting never removes the hurricane protection.
Installation by Winslow Windows & Doors in Westchester
Proper installation is the difference between a functioning rated assembly and a beautiful water leak. A NOA-rated bay or bow window performs only as well as its perimeter seal and structural anchoring. We install every unit following AAMA 2400/2410 standard practice, with AAMA 812 low-expansion foam perimeter sealant to establish the air and water barrier between frame and rough opening.
The process starts with a pre-install inspection of the rough opening. We check for rotted framing, out-of-plane walls, and inadequate header support - problems we see regularly in older Westchester homes. A bay window’s projection puts cantilevered load on the opening, and if the header is undersized or the rough sill isn’t level, the assembly will sag and bind over time.
We set the frame level, plumb, and square, then shim and anchor per the manufacturer’s instructions. The perimeter gets the AAMA 812 foam sealant treatment, exterior flashing, and interior caulking as required. A final water test confirms the seal before trim goes back on. Permitting awareness matters here: Westchester sits in an HVHZ jurisdiction, which means your permit application will reference the NOA or Florida Product Approval number for your specific configuration. We provide that documentation with your quote. Improper installation compromises the NOA-rated system entirely - which is why this product should never be a DIY or handyman-installed item.
Frequently Asked Questions - Bay & Bow Windows
Each unit is engineered to the design pressure your specific Westchester wind zone requires, up to +/-100 PSF. We match the rating to your address when we measure the opening, so you’re not buying more or less than your permit demands. Call (863) 251-5864 and we’ll confirm your wind zone during the free estimate.
Because bay and bow windows are custom fabricated to your opening, lead time typically runs several weeks from signed approval to delivery. Exact timing depends on the configuration, glass package, and manufacturer line you select. We’ll give you a firm production window on your quote so you can plan around it.
Yes. Your Westchester permit application will reference the NOA and Florida Product Approval numbers specific to your exact configuration. These numbers are issued per configuration, not as a product-wide rating, and we provide the documentation for your unit on your quote. Call (863) 251-5864 if your permitting office needs the submittal before you sign.
Yes. Bay and bow windows are entirely custom fabricated - panel count, panel width, projection depth, operator placement, and sill style are all determined from your opening and your preferences. There is no stock-size chart limiting what we can build and install in Westchester.
Wash the glass and frame with mild soap and water. Inspect the weep holes along the sill track every few months and clear any debris - clogged weep holes in a projecting bay or bow allow water to pool against the frame. Check the perimeter sealant once a year. If your home is close to the coast, rinsing salt spray off the frame each season helps preserve the finish. For anything beyond routine cleaning, call (863) 251-5864 and we’ll take a look.
