Product Overview - 3-Panel Sliding (3-Lite Roller) Windows

A three-panel horizontal roller configuration suits wider openings where a single fixed pane won’t do. You get laminated impact glass across all three lites, with smooth multi-panel gliding that feels effortless even on larger units. In Westchester, where hurricane code drives nearly every window decision, this profile gives architects and homeowners a way to keep sightlines open without weakening the envelope.

The frame comes in aluminum or vinyl. Aluminum suits contemporary and coastal builds, and it’s what you’ll see on many Westchester homes with clean stucco lines. Vinyl carries a softer look and requires less upkeep. Both materials hold the laminated glass firmly in the frame under impact because the PVB interlayer keeps the glass bonded to the frame rather than letting it blow inward. That’s the core principle behind every hurricane window we install.

You can configure the panels two ways: two fixed lites with one operable, or one fixed with two operable. The first works well when you want a large viewing area and only occasional ventilation. The second gives you a full two-panel opening for airflow, which matters in Westchester’s humid months. Either way, the track is built for the weight of laminated impact glass, so you’re not fighting a sticky glide.

We’ve installed these across Westchester in living rooms, dining rooms, and master suites where the opening spans six feet or more. They also appear on second-story front elevations looking out over the neighborhood. The point is that this is not a niche product: it’s the standard answer for any Westchester project that needs wide glass and hurricane code compliance.

Technical Specifications

Here’s what you’re choosing from when you spec a 3-panel sliding window with Winslow Windows & Doors:

• Frame materials: Aluminum or vinyl, both structurally reinforced for impact glazing.
• Track configurations: 3-lite with two fixed and one operable panel, or 3-lite with one fixed and two operable panels.
• Glass options: Laminated impact glass with PVB interlayer, Low-E insulated glass, tinted glass, or clear glass.
• Finish options: White, almond, bronze, black, or tan to match trim, stucco, and accent colors common across Westchester.
• Screen options: Retractable screen or sliding screen, depending on how often you want the opening completely clear.
• Design pressure: Matched to your wind zone, up to +100/-100 PSF, never higher.
• Compliance: Miami-Dade NOA and Florida Product Approval numbers available per configuration; engineered to Florida Building Code HVHZ requirements.

Every opening is measured and quoted individually. We don’t sell a stock unit and hope it fits your rough opening, especially not in an HVHZ jurisdiction like Westchester where the permit reviewer wants to see product numbers that match the paperwork.

Hurricane & Compliance Performance

Laminated Impact Glass – The PVB interlayer is what holds the glass in the frame under impact. Even if the outer pane shatters, the interlayer keeps the pane intact and bonded so wind and rain don’t enter the home. That’s the protection mechanism behind all the impact windows we install in Westchester.

Miami-Dade NOA / FL Product Approval – Each panel configuration carries its own Notice of Acceptance or Florida Product Approval number. We’ll verify the exact number against your specific quote and include it in your permit packet. No generic certificates, no hand-waving at the building department.

FBC / HVHZ Compliance – The product is engineered to Florida Building Code High-Velocity Hurricane Zone requirements. Westchester falls under HVHZ rules, so every window in your opening has to meet that standard, not just the ones facing the street.

TAS 201 / 202 / 203 Testing Context – HVHZ-rated products are tested under this protocol family. TAS 201 covers large-missile impact, TAS 202 covers cyclic wind-pressure loading, and TAS 203 covers forced-entry resistance. It’s the sequence that proves the window won’t fail after the first hit or the first gust cycle.

Design Pressure for Your Wind Zone – We specify the design pressure rating to your wind zone, up to +100/-100 PSF, never higher. If a house in Westchester sits on a canal, near open water, or on an elevated corner lot, the wind zone pushes the requirement up. We match the unit to the actual load, not a generic rating.

Energy Performance – Low-E and insulated glass options are available on the 3-lite roller profile. That lets you pair impact protection with heat gain reduction, which matters through Westchester’s long cooling season.

Color & Glass Options

Finish colors include white, almond, bronze, black, and tan. On Westchester’s older ranch and Mediterranean-influenced homes, almond and tan blend with warm stucco. White disappears into painted trim. Bronze and black work on newer builds with darker window package accents, and bronze reads especially well against barrel tile roofs.

For glass, clear laminated impact is the baseline. Tinted glass reduces glare and adds a little heat rejection if the opening faces west with late-afternoon sun. Low-E insulated glass makes sense if that wall catches full sun most of the day and you want the room cooler without overworking the AC. We’ll talk through what the opening actually faces before recommending one over another, because the right glass for a north-facing window in Westchester isn’t the same as one facing the afternoon sun.

Installation by Winslow Windows & Doors in Westchester

Installation is where an NOA-rated product either performs or doesn’t. A window tested and approved in a lab still depends on the fastening pattern, shimming, and perimeter seal being done right. We install per AAMA 2400/2410 practice, which covers measuring, setting, plumbing, and sealing the unit correctly. We also use AAMA 812 low-expansion foam around the perimeter so the seal stays continuous without pushing the frame out of square.

The process starts with a pre-install inspection. We check the rough opening for water damage, measure the jambs at three points, and confirm the existing header is sound before removing the old window. Then we set the new 3-panel unit level, plumb, and square. That matters more on a wide three-lite window than on a small single-hung because a wide opening magnifies any racking. If the frame is out of square by even a small margin, the panels bind in the track and the interlocks won’t close cleanly.

After setting, we run a final water test on the sills and check the panel glide in both directions. We finish the interior and exterior with clean trim lines and haul away the old unit. For Westchester specifically, we verify what the permitting office needs for your wind zone and include the Miami-Dade NOA or FL Product Approval paperwork that matches the exact configuration you bought.

Improper installation compromises the tested system. If the fasteners aren’t spaced as the approval requires, the window is only as good as the install. That’s why we don’t sell this product to a homeowner who wants a handyman to drop it in. We sell it installed, by our own crew, in Westchester, with the permit paperwork to back it.
