Garden Windows in Boca Raton, FL | Winslow Windows & Doors

A garden window is a projecting, box-style window with glass on three sides and a built-in shelf at the base. It creates a bright display ledge for plants, orchids, ceramics, or seasonal decor while pulling in light from three directions at once. In Boca Raton, where daylight is abundant and indoor-outdoor living defines the architecture, these windows make a kitchen, breakfast nook, or bathroom feel larger without adding square footage. Winslow Windows & Doors supplies and installs impact-rated garden windows across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines. We handle the entire project, from measuring and permit-ready documentation to a level, plumb, and square installation. Call (561) 816-5648 to discuss your opening.

Product Overview - Garden Windows

Garden windows extend outward from the wall plane, typically 12 to 18 inches, creating a glass canopy over a flat shelf. Every pane in our impact series uses laminated impact glass, so the shelf display gets the same hurricane protection as the rest of the home. That matters in Boca Raton, where a projecting window catches wind and debris from three exposed faces. The frame carries the load through reinforced corner joinery and mechanical fastening, not just sealant.

Architecturally, this window suits kitchens above the sink, breakfast areas, and bathrooms where homeowners want a display surface and natural light without a full bump-out addition. In South Florida homes, a garden window over the kitchen sink is one of the most requested upgrades because it turns dead wall space into a usable ledge. The shelf sill option gives you a flat interior surface wide enough for a row of potted herbs or a collection of glassware. Because the glazing is laminated on all four sides, that display area is not a weak point in the building envelope. Winslow Windows & Doors installs these windows in Boca Raton with the same anchoring and perimeter-sealing discipline we apply to every impact product we set.

Technical Specifications

We offer this product in two frame platforms, each with trade-offs worth knowing before you choose.

• Frame materials: Aluminum and vinyl. Aluminum carries larger glass packages and resists sag over long service life. Vinyl provides a thermal break and typically costs less for smaller openings.
• Glass options: Laminated impact glass with a PVB interlayer, Low-E insulated glass, tinted glass, and clear glass. Laminated is the impact-rated base layer; Low-E and tinting are performance add-ons for heat and glare.
• Finish options: White, almond, bronze, black, and tan. Finishes are applied at the factory for color consistency across the frame exterior and interior.
• Sill options: Shelf sill, standard on the garden window profile.
• Design pressure: Matched to your wind zone, up to +/-100, never higher.
• Compliance documentation: Miami-Dade NOA and Florida Product Approval numbers issued per configuration, verified on your specific quote.

Hurricane & Compliance Performance

Every garden window we quote for a Boca Raton home is engineered to the Florida Building Code High-Velocity Hurricane Zone standard. The specifics below explain what that means for this product.

Laminated Impact Glass - The glass package uses a PVB (polyvinyl butyral) interlayer sandwiched between two panes. Under impact, the glass may crack but the interlayer holds the shattered pieces in the frame, keeping the window sealed. Because a garden window has glass on three sides plus the top, all four glazing planes on our impact series carry this lamination. That includes the shelf-side glass, which some lower-cost products skip in the mistaken belief that an interior shelf face is less exposed. It is not. In a wind-driven rain event, every plane of a projecting window is a potential water and pressure entry point.

Miami-Dade NOA & Florida Product Approval - Each configuration of this product carries a Miami-Dade Notice of Acceptance or a Florida Product Approval number, issued per size, frame material, and glass package. The number that applies to your specific opening is verified on your written quote. Your building department in Boca Raton or Palm Beach County will look for this documentation before issuing a permit. We provide it with every order.

FBC / HVHZ Compliance - The product is engineered to Florida Building Code High-Velocity Hurricane Zone requirements. HVHZ is the stricter of the two Florida wind provisions and applies throughout Palm Beach County, including all of Boca Raton. A garden window without HVHZ documentation is effectively a paperweight here. The permitting office will reject it, and your insurer has grounds to deny coverage on the opening.

TAS 201 / 202 / 203 Testing Context - HVHZ-rated products are tested under the TAS protocol family. TAS 201 covers large-missile impact, TAS 202 covers cyclic wind-pressure loading, and TAS 203 covers forced-entry resistance. Our garden window configurations carry test reports under this protocol family. When someone tells you a window is “impact rated” but cannot produce a TAS-based test report, what they are selling is a label, not an engineered assembly.

Design Pressure Matched to Your Wind Zone - Design pressure is a measurement in pounds per square foot, not a wind speed. Our garden windows are specified to a design pressure matched to your wind zone, up to +/-100, never higher. A competent dealer calculates the required DP from your site’s exposure category and the opening’s position on the building, then selects the frame and glass package accordingly. We do not sell a single “one size fits all” DP rating for every home in Boca Raton. Coastal pockets need one calculation; inland subdivisions need another.

Energy Performance Options - Low-E and insulated glass options are available for homeowners who want the impact protection without the solar heat gain that clear laminated glass allows. In a south-facing kitchen window in Boca Raton, Low-E insulation makes a measurable difference in afternoon cooling load. The garden window’s projecting shape adds surface area, so the glass package choice matters more here than on a flush window.

Color & Glass Options

Boca Raton’s housing stock runs from mid-century ranches to Mediterranean revival estates, and the finish palette covers that range. White and almond suit traditional and coastal homes where the window should read as trim. Bronze and black are our most common choices for contemporary and Mediterranean exteriors with dark roofs or dark aluminum accents. Tan bridges modern and classic, particularly on stucco homes with warm neutral tones.

Clear laminated glass is the honest workhorse: maximum light, full impact protection, no color shift. Tinted glass cuts glare and provides privacy during the day, which matters for garden windows on a street-facing elevation. Low-E insulated glass is the choice when the window faces west or south in the afternoon, since the projecting shape exposes more glazing surface to direct sun than a flat window of the same width. For kitchens where the shelf holds plants, many Boca Raton clients pair clear laminate on the front face with Low-E insulated on top to keep the greenhouse effect from overheating the room.

Installation by Winslow Windows & Doors in Boca Raton

A garden window is only as strong as the opening it is anchored into. The product carries an NOA or Florida Product Approval in its manufactured state, but that approval assumes a compliant installation. A poorly anchored or inadequately sealed garden window will leak, deflect, and in a storm, fail exactly where the wall meets the frame. This is why our process in Boca Raton follows a defined sequence on every garden window we set.

We begin with a pre-install inspection of the rough opening, checking the existing header, sill, and wall cavity for rot, termite damage, or deflection. The new unit is shimmed and fastened level, plumb, and square before any sealant goes on. We use AAMA 812 low-expansion foam as the perimeter seal, following AAMA 2400/2410 installation practice for flashing and drainage integration. The window is anchored through the frame, not just the nailing fin, because a projecting window applies levered loads to its fasteners that a flush window does not. After setting, we run a water test, inspect the interior for air movement at the perimeter, and clean the site. We also track the permitting path for HVHZ jurisdictions in and around Boca Raton, so the NOA or Florida Product Approval document that matches your opening is what gets submitted, not a generic data sheet for a different size.

Coastal exposure, salt air, and high afternoon heat all punish window installations in Boca Raton. The right product installed the wrong way will not survive its first insurance inspection, let alone a real storm. That is the reason we quote installation as part of the project, not as an optional add-on.
