Casement Windows

Casement Windows in Naples, FL | Winslow Windows & Doors

Casement windows are the side-hinged, crank-operated workhorses of Florida coastal architecture, and for good reason. They seal tighter than almost any window style when closed, and they swing fully outward to catch Gulf breezes when you want air moving through the house. For Naples homeowners, an impact-rated casement means you don’t have to choose between hurricane protection and real ventilation. Winslow Windows & Doors supplies and installs casement windows across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, sized and configured for your opening, finished to match your home, and set to hold under Florida wind loads. Call (239) 899-6411 to talk through your project or schedule a free on-site measurement.

Product Overview - Casement Windows

A casement window is a single sash that hinges on the side and opens outward with a crank or lever. What makes this profile so well suited to hurricane-prone construction is the way it closes: the sash presses into the frame around its entire perimeter, creating a full compression seal that air, water, and wind have a hard time getting past. There is no sliding track to drain, no meeting rail to leak at the center. When you add laminated impact glass and a heavy-duty locking mechanism, you get a window that is genuinely part of the building envelope, not a weak point in it.

Architecturally, casements fit a wide range of Naples homes. You’ll see them on Old Florida cottages in Old Naples, on Mid-century ranches in Moorings, and on newer Mediterranean-inspired builds in Pelican Bay and Lely Resort. Because the sash opens outward to nearly 90 degrees, a pair of casements side by side can catch and direct even light breezes into the room, which matters in Southwest Florida where afternoons can be still and humid. The single sash also gives you a larger uninterrupted glass area than a double-hung of the same rough opening.

We order our casements in aluminum or vinyl frames. Aluminum is the classic choice for coastal architecture: rigid, narrow sightlines, available in darker finishes that won’t look out of place on a modern home. Vinyl is the lower-maintenance option, thermally efficient, and completely immune to salt air corrosion. Both are built to the same impact standard, and both are installed the same way by our crew in Naples.

Technical Specifications

• Frame materials: Aluminum or vinyl. Aluminum for maximum rigidity and narrow sightlines; vinyl for thermal efficiency and low maintenance.
• Glass options: Laminated impact glass with a PVB interlayer, Low-E insulated glass, tinted glass, or clear glass. Laminated impact glass is the hurricane-rated option; Low-E and tinted glass can be combined with impact lamination depending on the configuration.
• Finish options: White, Almond, Bronze, Black, and Tan. Finish availability varies by frame material and manufacturer line.
• Screen options: Fixed screen or retractable screen. Retractable screens tuck away when not in use so they don’t block the view.
• Operation: Crank or lever operated, side-hinged, opens outward.
• Hardware: Multi-point locking hardware along the hinge-side and bottom of the sash. Hardware finish matched to frame color.

Hurricane & Compliance Performance

Laminated Impact Glass

The core of the impact rating is the glass itself. Laminated impact glass is two panes of glass bonded with a PVB (polyvinyl butyral) interlayer. When something hits the outer pane, the glass may crack, but the PVB layer holds the broken pieces together and keeps the window sealed in the frame. That means no wind-driven rain entering the house, no sudden pressure change lifting your roof, and no flying shards inside the living room.

Miami-Dade NOA / Florida Product Approval

Our casement configurations carry Miami-Dade NOA (Notice of Acceptance) and Florida Product Approval numbers. These are issued per configuration, not per product family, so the exact number depends on your size, glass, and frame combination. We include the correct NOA or Florida Product Approval documentation with your quote and permit submittal. This documentation is non-negotiable in Naples and Collier County: without it, the building department will not sign off on your window replacement.

FBC/HVHZ Compliance

The product is engineered to Florida Building Code (FBC) High-Velocity Hurricane Zone (HVHZ) requirements. That’s the stricter of Florida’s two wind-load design tiers, covering Collier County and the rest of the southeast Florida coastal zone. HVHZ compliance means the frame, glass, hardware, and anchoring methods were designed as one system to hold the window in the wall under hurricane conditions.

TAS 201/202/203 Testing Context

HVHZ-rated products are tested under a protocol family that includes TAS 201 (large-missile impact), TAS 202 (cyclic wind-pressure loading), and TAS 203 (forced-entry resistance). TAS 201 involves firing a lumber missile at the glass and frame; TAS 202 repeatedly cycles wind pressure against the closed, locked sash; TAS 203 tests the locked window against prying and forced entry. Our casements are tested under these standards as part of their product approval.

Design Pressure for Your Wind Zone

Design pressure is a PSF (pounds per square foot) rating that tells you how much wind load a specific window configuration can resist. Our casements are ordered with design pressures matched to your wind zone, up to +/-100, never higher. The exact rating depends on the size of the opening, the frame material, and the glass package. A larger window in a coastal wind zone needs a different configuration than a smaller window in an inland zone, and we specify accordingly. If you want the design pressure for your specific sizes, call us at (239) 899-6411 and we’ll work it up.

Energy Performance

Low-E and insulated glass options are available for energy performance. Low-E coatings reduce solar heat gain through the glass without tinting the view, which matters in Naples when your windows face west. Insulated glass adds a second airspace that reduces heat transfer through the glass itself. These options can be paired with impact lamination in most configurations.

Color & Glass Options

Finish selection is where the window either disappears into the home or becomes a design element. White and Almond are the classic choices for Naples ranches and condominiums, and they’re the lowest-maintenance finishes in direct sun. Bronze and Black read as more contemporary and work well on modern homes in communities like Aqualane Shores or on newer construction where darker frames are part of the design. Tan is a softer neutral that fits the Mediterranean and Spanish-influenced elevations you see in parts of Old Naples and Port Royal.

On the glass side, clear laminated impact glass is the honest workhorse: it protects the home and doesn’t change the view. Low-E laminated is what we suggest for west-facing windows or any room that gets heavy afternoon sun. Tinted glass cuts glare and solar heat, which is useful on pool cages and east-facing bedrooms. Insulated glass adds a level of thermal and acoustic performance that single-pane impact glass doesn’t have, and it is available on both vinyl and aluminum lines. When we quote the job, we walk through each opening and recommend glass based on what that wall actually faces.

Installation by Winslow Windows & Doors in Naples

An impact-rated casement window is only as good as the opening it’s set in. The NOA and Florida Product Approval are tied to the window as installed in a wall assembly, which means the installation itself is part of the compliance. A window anchored loosely, or set out of square, or sealed incorrectly, does not perform to its tested rating. That’s why our installation process in Naples follows a specific sequence on every job.

We start with a pre-install inspection of each opening. We check the rough opening dimensions, the condition of the existing buck or framing, and we look for signs of water intrusion or rot around the old window. If the substrate is compromised, we address it before the new window goes in. We don’t set a new window into a rotten opening and call it done.

The window is set level, plumb, and square, shimmed properly at the anchor points, and fastened per the manufacturer’s anchoring schedule for the product’s approval. We install per AAMA 2400/2410 practice for mounting, flashing, and sealing. The perimeter is sealed with AAMA 812 low-expansion foam, which fills voids and air-seals the gap without putting pressure on the frame. After the window is set, we run a water test to verify the seal, then clean up the job site and haul off the old windows.

Naples-specific conditions matter here. Coastal exposure means salt air and wind-driven rain are constant factors. Wind zone requirements vary even within Collier County, so the anchoring that works for an interior Naples unit may not be what a Gulf-front window requires. Permitting in Naples and unincorporated Collier County can carry HVHZ-specific plan review requirements, and we coordinate the documentation with your permit. If you’re replacing windows in a Naples condo, tower or mid-rise, we also coordinate the engineering and access with your association. The goal is the same in every case: a window that’s set correctly the first time, closes the way it was designed to, and stays put in a storm.
