AfterBay & Bow Windows in South Miami, FL | Winslow Windows & Doors
Bay and bow windows do something no flat window can: they push the glass outward, add usable interior square footage, and open up a wider view of the street, the yard, or the water. In South Miami, where hurricane season is a fact of life, these projecting multi-panel configurations have to do all that while standing up to wind-borne debris and pressure cycling nobody thinks about until a storm is in the Gulf. Winslow Windows & Doors has installed impact-rated bay and bow configurations across South Miami for years, and every installation is custom fabricated to the opening, engineered to your wind zone, and set level, plumb, and square. Call (850) 930-1813 to schedule a free measurement and quote.
Product Overview - Bay & Bow Windows
A bay window is a three-panel projection, typically a large fixed center panel with two angled side units, often venting casements or double hungs. A bow window uses four to six panels arranged in a gentler arc. Both create a reading nook, a plant shelf, or a breakfast alcove, but in Florida they carry an extra job: forming part of the home’s structural defense against hurricane winds and impact. Our Bay & Bow Windows install with laminated impact glass as the core glazing option, set into custom-fabricated aluminum or vinyl frames that match the structural demands of the High-Velocity Hurricane Zone.
What makes this profile suited to hurricane-prone construction isn’t just the glass. It’s the way the unit is engineered as a projecting assembly. The mullions, fasteners, and seat board all have to resist both positive and negative pressure loads, and they have to keep doing it for decades after the first installation. In South Miami’s salt air and humidity, we specify frames and hardware that won’t corrode, bind, or loosen. Architecturally, bays and bows fit the low-slung ranches and Mediterranean-inspired homes common in neighborhoods like Schenley Park, Ludlam, and the areas around Sunset Drive. The added depth also gives you a wider interior sill line, which homeowners use for seating, storage, or display space.

Hurricane & Compliance Performance
A PVB (polyvinyl butyral) interlayer bonds two layers of glass into a single pane. When a piece of debris strikes, the glass cracks but the PVB holds the shards in the frame, keeping the building envelope sealed. That’s the mechanism that keeps wind and water outside during a blow.
Our bay and bow configurations carry Miami-Dade NOA (Notice of Acceptance) and Florida Product Approval numbers issued per configuration. The exact number applies to the specific sizes and glass types you select, so we verify it on your written quote before fabrication begins.
Every unit is engineered to Florida Building Code High-Velocity Hurricane Zone requirements. FBC-HVHZ is the strictest wind-load standard in the state, written specifically for Miami-Dade and Broward construction. South Miami falls under that jurisdiction.
HVHZ-rated products are tested under a family of protocols: TAS 201 for large-missile impact, TAS 202 for cyclic wind-pressure loading, and TAS 203 for forced-entry resistance. Passing all three is what separates a real impact product from a window that just looks like one.
Design pressures are matched to your wind zone, up to +/-100, and never higher. We don’t upsell you into a rating your house doesn’t need, and we don’t let an under-rated unit slip into an opening that demands more. Your quote specifies what the structure requires.
For South Miami’s cooling-dominated climate, we can pair laminated impact glass with Low-E insulated glazing. The insulated unit reduces solar heat gain through the big center picture panel, and Low-E coatings help cut afternoon glare without dark tint. It’s the right pairing for east and west exposures.
Color & Glass Options
Five finish colors cover most of the architecture you see driving through South Miami from Old Cutler Road to the neighborhoods around Dante Fascell Park. White and Almond fit the traditional Florida ranch and cottage styles. Bronze and Black read well on modern builds and Spanish-Mediterranean facades with dark roof tiles and iron details. Tan splits the difference for stucco homes with warmer earth tones. All finishes are applied to the frame extrusion, not painted on at the job site, so the color holds up to sun and salt exposure.
For glass, clear laminated impact is the honest workhorse. It keeps the view as clean as possible while giving you the impact rating your permit package requires. Tinted laminated glass cuts daytime heat and glare, which matters for big southern or western bays that catch the afternoon sun. Low-E insulated glass adds an insulating air space and a reflective coating with better solar control than tint alone. We’ll spec the right combination based on which way the opening faces and how much afternoon sun the room already collects.
Installation by Winslow Windows & Doors in South Miami
Every bay or bow window is only as good as the rough opening behind it. A projecting unit carries its weight differently than a standard flat window. It relies on a seat board or support framing beneath it, a watertight perimeter, and anchor points that hold the assembly against wind pressure that tries to push it in or pull it out. That’s the reason we don’t sell this product as a drop-ship item. We measure, fabricate, and install it ourselves.
Before fabrication, we inspect the rough opening, the header, the sill condition, and the substrate. Then we set the unit level, plumb, and square. There’s no forcing a bay into an out-of-square opening and caulking over the gap. We install per AAMA 2400/2410 practice, and we lay a continuous AAMA 812 low-expansion foam perimeter sealant behind the nailing flange to create an air and water seal that moves with the building. After the frame is anchored, we run a final water test around the sill and mullion joints. In South Miami, we’re also familiar with what the building department wants on a permit submittal for HVHZ jurisdiction. We can pull the permit on your job and schedule the inspection, so the bay window doesn’t become a permit problem later. Improper installation compromises the NOA-rated system. A correctly built product installed badly fails exactly the way a not-rated product fails. The difference is this one is supposed to protect you.
Because South Miami homes run close to the coast and into the higher wind zones, we pay attention to things inland builders might skip: corroded header fasteners, re-mediating rotted sill plates, and tying the unit’s seat framing to structural members rather than trim. If your home is older, we include that in the pre-install walkthrough, not as a surprise change order.
Frequently Asked Questions - Bay & Bow Windows
Design pressures are matched to your specific wind zone, up to +/-100, and never higher. The unit is engineered for the Florida Building Code High-Velocity Hurricane Zone that South Miami requires. We confirm the exact DP rating on your written quote.
Bay and bow windows are custom fabricated to your opening, so lead time depends on the size, configuration, glass package, and current production schedule. Most orders move from measure to fabrication release in a few weeks. We give you a written lead time on the quote, not a guess over the phone. Call (850) 930-1813 and we can walk you through current timing.
Yes. A South Miami permit for a bay or bow window with impact glazing requires the Miami-Dade NOA or Florida Product Approval number that matches your size and glass configuration. Winslow Windows & Doors provides that documentation with your quote so your permit submittal is complete before fabrication starts. Most homeowners have us pull the permit as part of the installation.
Yes. Bays and bows are not stock products. We custom fabricate the frame to your rough opening and your chosen configuration, whether you want a three-panel bay with venting side casements or a five-panel bow with picture windows across the arc. Your seat board depth can also be sized to fit nook seating.
Wash the glass with a mild soap and water, rinse the frame tracks, and for coastal South Miami homes, give the exterior frame a freshwater rinse a few times a year to keep salt from sitting on the finish. Check the perimeter caulking annually. If the sealant pulls away from the stucco, have it re-applied before it lets water get behind the frame. That’s the one thing we tell every customer to keep an eye on.
