AfterGarden Windows in West Palm Beach, FL | Winslow Windows & Doors
A garden window is a projecting box-style impact window with glass on three sides and a shelf base built in. It gives you a sunny display ledge for orchids, herbs, or collectibles while the laminated glass on every pane keeps the window sealed against Florida weather. We’re Winslow Windows & Doors, and we’ve been installing hurricane-rated windows across West Palm Beach for years. These are not decorative add-ons. They are structural openings in a wind-borne debris zone, which means the anchoring, flashing, and perimeter seal are as important as the glass itself. Call (561) 660-9539 to talk about a garden window for your home.
Product Overview - Garden Windows
A garden window projects outward from the wall plane, usually between 12 and 18 inches, creating a small greenhouse-like bay with glass on the front, left, and right sides and a level shelf at the base. In West Palm Beach that shelf gets used for everything from starter plants to cookbooks to a cat’s favorite afternoon nap spot. The window works well over a kitchen sink, in a breakfast nook, or in a bathroom where you want daylight without giving up wall space.
What makes this profile different in a hurricane-prone market is the engineering behind the projection. The box structure has to resist wind loads on three separate glazed planes at once. Our garden windows are built with aluminum or vinyl frames and laminated impact glass on every pane, not just the front. The shelf sill is integrated and sloped so water drains outward. The whole assembly is engineered to Florida Building Code High-Velocity Hurricane Zone requirements, which is the standard that governs construction in West Palm Beach and throughout Palm Beach County. We carry this product across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, and we match the right line to the wind zone and elevation of your specific home rather than pushing one option on every job.
Technical Specifications
- Frame materials: Aluminum or vinyl, selected for the exposure and finish you need
- Glass options: Laminated impact glass with PVB interlayer, Low-E insulated glass, tinted glass, clear glass
- Finish options: White, almond, bronze, black, tan
- Sill options: Shelf sill, integrated with the projection and sloped for drainage
- Wind rating: Design pressures matched to your wind zone, up to +/-100, never higher than what your opening actually requires
- Compliance: Miami-Dade NOA and Florida Product Approval numbers available per configuration, engineered to FBC High-Velocity Hurricane Zone requirements
We specify these windows per opening. A garden window on a second-story east-facing wall in a coastal exposure zone is a different spec than one on a ground-floor interior wall. We verify the design pressure your particular configuration needs before we ever quote it.
Hurricane & Compliance Performance
Laminated Impact Glass
Every pane in the garden window carries laminated impact glass with a PVB (polyvinyl butyral) interlayer. Under impact, the interlayer holds the glass in the frame rather than letting shards enter the home. That’s the core of the impact protection on all three glazed sides of the projection.
Miami-Dade NOA / Florida Product Approval
This product carries Miami-Dade NOA (Notice of Acceptance) and Florida Product Approval numbers, issued per configuration. When we quote your specific size, glass package, and frame, we verify the exact approval number that applies to that configuration so your permit submittal is clean.
FBC / HVHZ Compliance
Engineered to Florida Building Code (FBC) High-Velocity Hurricane Zone (HVHZ) requirements. In West Palm Beach, that is the governing code for any window opening. There is no downgrading the standard because the window happens to protrude from the wall.
TAS 201 / 202 / 203 Testing Context
HVHZ-rated products are tested under a protocol family that includes TAS 201 for large-missile impact, TAS 202 for cyclic wind-pressure loading, and TAS 203 for forced-entry resistance. This product is tested in that framework, which is why it can carry a Miami-Dade NOA.
Design Pressure for Your Wind Zone
Design pressures are matched to your wind zone, up to +/-100, and never higher than the calculation calls for. Overspecifying is not a virtue. It wastes money and can change the way the window seats in the rough opening. We calculate per opening and per elevation.
Energy Performance
Low-E and insulated glass options are available for the garden window. In a projecting box with three glass surfaces, the glass package matters more for solar gain than it does on a flush window. Low-E keeps the display shelf from becoming a heat trap in a West Palm Beach afternoon sun.
Color & Glass Options
White and almond finishes are the most common choices we see on West Palm Beach homes built in the 1970s through the 1990s, and they keep a clean look on cottage and ranch styles. Bronze and black finishes read more contemporary and hold up well on newer construction with dark window trim or black hardware. Tan works on Mediterranean and Spanish-style homes where the exterior stucco carries warm earth tones. All five finishes are available in the same aluminum or vinyl frame.
On the glass side, clear laminated is the baseline for impact protection. Tinted laminated cuts glare and heat gain, which matters on a west-facing garden window in summer. Low-E insulated glass gives you the best thermal performance and is worth considering if the window faces south or west. For any configuration, the shelf sill stays the same: a stable, sloped, integrated surface with the laminated glass protection on every pane.
Installation by Winslow Windows & Doors in West Palm Beach
We install garden windows differently than a standard flush window because the projection changes the load path. The window cantilevers out from the wall, so the anchoring at the top, sides, and bottom carries more than glass weight. It carries wind uplift and gravity working together. We start every install with a pre-install inspection of the rough opening, the surrounding framing, and the existing water management details.
We set the window level, plumb, and square, shimming at the anchor points rather than cranking the frame into position. The perimeter gets sealed with AAMA 812 low-expansion foam and a continuous sealant detail at the exterior. Our installation practice follows AAMA 2400/2410 standards, which govern how a window should be installed to perform in the real world, not just on a test rig. We finish with a water test at the sill and head, then clean up the work area completely.
In West Palm Beach, a garden window is a permitted opening. The HVHZ jurisdiction means the product approval number has to match what the plans call for, and the installation has to match the approval. A window can carry a Miami-Dade NOA and still leak or fail if it is set wrong. We know what Palm Beach County plan reviewers look for, and we build our installation sequence around passing the inspection the first time.
Frequently Asked Questions - Garden Windows
The design pressure is matched to the wind zone of your specific home in West Palm Beach, up to +/-100 and never higher than the calculation requires. We determine the required rating based on your elevation, exposure category, and roof zone at the opening, then match the configuration to it. Call (561) 660-9539 for the exact rating on your opening.
Most garden windows in our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines run four to eight weeks from approved measurements and deposit, depending on the glass package and finish. Custom sizing or a less common finish can extend that. We confirm the production schedule at quote time so you are not guessing.
Yes. In West Palm Beach, any replacement window opening in an HVHZ jurisdiction requires a product approval submittal that matches the exact configuration being installed. We provide the NOA or Florida Product Approval number applicable to your size, glass, and frame on your quote so your permit package is complete. Call (561) 660-9539 and we’ll walk you through what your particular municipality asks for.
Yes, within the tested and approved size range for the product line. The width, projection depth, and height are selected to fit your rough opening and your use for the shelf. The approval number changes with the configuration, so we verify each combination rather than assuming one approval covers every size.
Wash the glass with mild soap and water, and wipe the frame and the shelf sill regularly. Check the exterior weep holes at the base of the projection once or twice a year to make sure they drain freely. In West Palm Beach, salt air and heavy rain mean the sill slope and the sealant bead should be inspected annually. If you want us to come check the perimeter seal, call (561) 660-9539.
