Garden Windows

Garden Windows in Miami, FL | Winslow Windows & Doors

Garden Windows are the product Miami homeowners ask us about when they want a real display area in the kitchen without giving up hurricane protection. It’s a projecting box-style window that extends outward from the wall, with glass on the front and both sides, plus a built-in shelf at the base. That shelf is where orchids, herbs, cookbooks, and family heirlooms end up living. In a Florida home, a garden window has to do two jobs at once: give you that display space and hold up to a real storm. That’s exactly what the Impact Series Garden Windows from Winslow Windows & Doors are built for. We install them across Miami and Miami-Dade County, and we’ve been doing so with the kind of care that ensures the opening stays level, sealed, and code-compliant from day one.

Product Overview - Garden Windows

A garden window is a box window. The frame projects outward, typically 16 to 24 inches beyond the exterior wall line, creating a small greenhouse-like alcove inside your home. Glass on three sides: front, left, and right. Above, either a sloped glass top or a solid insulated top depending on the configuration. Below, a shelf sill that’s wide enough for potted plants or a collection of glassware. When a home in Miami has one of these, it’s almost always in the kitchen above the sink, where the shelf catches morning light and gives you something better to look at than a blank wall.

Now here’s the part that separates a Florida-spec garden window from what you’d see on a house in Ohio. Every pane of glass on this unit is laminated impact glass. That includes the two side lites, not just the front. In a hurricane, debris doesn’t discriminate by angle. A garden window with impact-rated glass on all three faces plus the top is what makes this product viable in Miami-Dade’s High-Velocity Hurricane Zone. We frame these windows in either aluminum or vinyl, both engineered to carry the load those three glass planes create when wind pressure hits the projection. Winslow Windows & Doors installs this product across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, which gives you real options when it comes to frame profile, finish, and glass package.

The shelf itself is not an afterthought. It’s a structural piece. It has to support the weight of whatever you place on it while also shedding water away from the frame. A poorly designed or poorly installed shelf sill is where garden windows leak. When we install one in a Miami home, we pay particular attention to how that sill marries with the surrounding wall, because that detail determines whether the window lasts 20 years or becomes a maintenance headache in five.

If you’re considering a garden window for a home in Coral Gables, Pinecrest, Kendall, or anywhere else in the Miami area, call us at (863) 862-5435. We’ll help you figure out whether this profile makes sense for your wall and your wind zone.

Technical Specifications

Here’s what the Impact Series Garden Windows are made of and how they can be configured for your Miami home. Every option shown below is available through Winslow Windows & Doors, and what we recommend depends on where you live, how your home faces the water, and what the permitting office requires for your specific property.

• Frame materials: Aluminum or Vinyl. Aluminum is the default in Miami’s coastal construction for its strength and low maintenance. Vinyl is a strong second choice when you want a softer look or tighter budget without sacrificing impact approval.
• Glass options: Laminated Impact Glass (PVB Interlayer), Low-E Insulated Glass, Tinted Glass, Clear Glass. Laminated impact glass is standard for storm protection. Low-E adds thermal performance. Tinted and clear let you control the look.
• Color and finish options: White, Almond, Bronze, Black, Tan. Bronze and black read coastal modern. White and almond fit the classic Miami Mediterranean palette. Tan bridges the gap.
• Sill options: Shelf Sill. That’s the standard on this product, and for good reason. It’s the whole point of the window.
• Design pressure: Matched to your wind zone, up to +/-100 PSF, never higher. We’ll explain what that number means for your house below.

The exact size range depends on the product line you select, because our PGT and CGI garden window frames have different maximums than what ES Windows or ECO can do. The best way to know what fits your opening is to measure it, or let us do it for you. Call (863) 862-5435 for a free on-site measurement in the Miami area.

Hurricane & Compliance Performance

This is the section that matters most in Miami. A garden window is a beautiful thing, but if it doesn’t meet Miami-Dade NOA standards and the Florida Building Code’s High-Velocity Hurricane Zone requirements, it’s not something we’ll sell you, and it’s not something your municipality will let you install. Here’s how the Impact Series Garden Window meets the bar.

Laminated Impact Glass

Every pane on this window is laminated impact glass with a polyvinyl butyral (PVB) interlayer. When debris hits the glass, the PVB layer holds the broken pieces in place rather than letting them spray into your kitchen. The glass stays in the frame, the envelope stays sealed, and wind-driven rain stays outside. For a garden window with three exposed glass faces, this is non-negotiable.

Miami-Dade NOA / Florida Product Approval

This product carries Miami-Dade Notice of Acceptance and Florida Product Approval numbers, issued per configuration. That means the exact window dimensions, frame material, and glass package you order have been evaluated and approved for use in HVHZ jurisdictions. We verify the specific approval number on your quote and include it with your permit submittal package.

FBC / HVHZ Compliance

The garden windows we install are engineered to Florida Building Code High-Velocity Hurricane Zone requirements. That’s the strictest building code standard for windborne debris regions in the United States. A window that’s HVHZ-compliant is one that a Miami-Dade or Broward building official will sign off on without hesitation.

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. These three tests simulate what actually happens in a hurricane: a 9-foot 2×4 slamming into the glass, wind gusting in cycles rather than one steady blow, and the frame holding secure against someone trying to force it from outside. Garden windows with impact glass on all three faces undergo the same protocols as any other opening in the envelope.

Design Pressure Matched to Your Wind Zone

We match design pressure to your specific wind zone, up to +/-100 PSF, never higher. Design pressure is a structural rating, not a wind-speed claim. It tells an engineer how much positive and negative pressure the assembled window can absorb repeatedly without failing. We don’t oversell a rating your home doesn’t need, and we don’t undersell one that your permitting office will flag.

Energy Performance

Low-E and insulated glass options are available on this product. If your Miami kitchen gets blasted with afternoon sun, an insulated Low-E package reduces heat gain through the glass and makes the room more comfortable without losing the daylight the garden window is there to capture.

Color & Glass Options

The five finish options on this window are not just color choices. They should align with your home’s architectural language. In Miami, where Spanish Mediterranean, Florida ranch, and modern coastal homes sit on the same block, the frame color is as much a design decision as the cabinet hardware.

White and Almond are the two we recommend most for older Miami homes with stucco or wood siding. They read neutral and clean, and they keep the focus on what’s inside the garden window, not the frame around it. Bronze and Black are the strong choices for contemporary builds in neighborhoods like Edgewater, the Design District, or any new construction with darker window packages. They make the window recede into the wall so the shelf display floats. Tan splits the difference for earth-toned Mediterranean homes in Coral Gables or Coconut Grove.

Glass choice depends on what the window faces. Clear laminated impact glass gives you the truest light and the best view of whatever you display. Tinted glass cuts glare, which matters in a west-facing Miami kitchen where the afternoon sun can be punishing. Low-E insulated glass is the energy play: it costs more up front, but it makes the room noticeably cooler in summer. You can pair Low-E with tint for maximum heat rejection, and we’ll help you weigh the cost against the comfort benefit. Call (863) 862-5435 and we’ll walk you through samples at your home.

Installation by Winslow Windows & Doors in Miami

Here’s the thing about a garden window, more so than a flat window: the installation makes or breaks it. A garden window projects outward past the building envelope. That means wind load, water shedding, and drainage plane continuity all have to be handled correctly or the window leaks, the wall rots, and the NOA-rated system is compromised. A product can pass every TAS test in a Florida laboratory and still fail in your home because someone installed it in a rush with spray foam and hope.

Winslow Windows & Doors installs garden windows in the Miami area using the same practices we use on every impact opening. That starts with a pre-installation inspection of the rough opening: checking for rot, verifying framing dimensions, and confirming the existing flashing condition. Then we set the window level, plumb, and square. On a garden window with a projecting shelf, level matters even more than usual, because an out-of-level shelf will tilt potted plants and hold water in the wrong places.

We seal the perimeter with AAMA 812 compliant low-expansion foam, then finish the exterior with the proper flashing and sealant. Our installation practice follows AAMA 2400 and 2410 standards, which address installation methods and materials for windows and doors. After the window is set, we run a water test to confirm no leaks at the sill, corners, or side flanges. Then we clean up and haul everything away.

Permitting is part of this too. In Miami-Dade County and most HVHZ jurisdictions, you cannot replace a window without a permit, and the permit application requires the product’s NOA or Florida Product Approval documentation. We know what the local building departments want to see, and we include the right paperwork with every garden window we sell. Coastal exposure in neighborhoods like Key Biscayne or Surfside adds another layer of wind-zone scrutiny, and we make sure the design pressure rating on your window matches what the permit reviewer expects. Call (863) 862-5435 to schedule a pre-install inspection or start the quote process.

Frequently Asked Questions - Garden Windows

What wind zone or design pressure is the Garden Window rated for?
Design pressure is matched to your specific wind zone, up to +/-100 PSF, and never higher than the configuration requires. That’s not a wind-speed rating. It’s the structural load capacity of the assembled window, and we verify it against Miami-Dade wind maps and your property’s exposure category before quoting. Call (863) 862-5435 and we’ll pull the right number for your address.

What is the lead time for a garden window in Miami?
Lead time depends on the product line and glass package you select. Impact-rated laminated glass with custom sizes and color finishes can add weeks compared to stock sizes, and coastal Miami orders sometimes take longer because of the NOA documentation step. We’ll give you a written delivery estimate when you place the order. For a current projection on your specific configuration, call (863) 862-5435.

Does a garden window require a Miami-Dade NOA or Florida Product Approval submittal for my permit?
Yes. Any impact-rated window installed in an HVHZ jurisdiction like Miami-Dade must have a current NOA or Florida Product Approval on file with the permit package. We include the correct approval number and documentation for your specific garden window configuration with every order, and we flag any size or glass combination that might require a different submittal.

Can I customize the size or configuration of the garden window?
You can customize the width, height, projection, glass package, and frame finish within the structural limits of the product line you choose. The side lites, top glass, and shelf sill are fixed components of the garden window profile, but their dimensions adapt to your opening. We’ll confirm what your rough opening can support before you order. Call (863) 862-5435 for exact options.

How do I maintain the garden window frame?
For aluminum and vinyl frames in Miami, maintenance is mostly about the perimeter. Wash the glass and frames with mild soap and water twice a year, and keep the exterior drainage paths at the sill clear of leaves and salt buildup. If you live near the coast in neighborhoods like Key Biscayne or North Beach, rinse the frame more often, because salt spray accelerates surface wear on aluminum finishes. The shelf inside just needs a wipe-down. Call (863) 862-5435 if you ever see condensation between panes or water at the sill, and we’ll take a look.
