Product Overview - 3-Panel Sliding (3-Lite Roller) Windows
A 3-Panel Sliding (3-Lite Roller) window is exactly what the name describes: three horizontal glass lites riding on a smooth gliding track, configured so two panels open and one stays fixed, or one opens and two stay fixed. In Palm Beach, FL, this profile earns its keep on wide bedroom, living-room, and patio-facing openings where a single-panel slider would be too narrow to code or would look undersized for the wall. The three-lite format spans broader rough openings while keeping each moving panel light enough to operate with two fingers.
The hurricane-grade version we install carries a laminated impact glass construction with a PVB (polyvinyl butyral) interlayer across all three lites. That interlayer is what holds the glass in the frame if a branch or roof tile strikes the window during a storm; the glass may crack, but it stays put instead of blowing into the house. We build these windows in both aluminum and vinyl frames. Aluminum gives you thinner sightlines and a stiffer frame, which matters on wide coastal elevations; vinyl brings excellent thermal performance and lower maintenance. Both take the same impact glass and both meet the Florida approval criteria we discuss below.
Architecturally, the 3-Panel Sliding window suits Florida ranch homes, Palm Beach-style estates, and anywhere you want a broad glass expanse that doesn’t hinge outward or crank. Our installers have placed these on Singer Island condominiums, in Boca Raton single-family rebuilds, and throughout Palm Beach County. Since every opening is measured on site and every configuration is ordered to match that opening’s wind zone, you’re not getting a generic slider that happens to fit; you’re getting a window system matched to your address.

Hurricane & Compliance Performance
Laminated Impact Glass
Every lite in our 3-Panel Sliding (3-Lite Roller) windows carries a PVB (polyvinyl butyral) interlayer, whether you choose clear, tinted, or Low-E insulated glass. That interlayer grips the glass even when it cracks under impact, holding the panel together so the opening stays sealed during a Palm Beach County storm.
Miami-Dade NOA / Florida Product Approval
Each configuration we order comes with its own Miami-Dade Notice of Acceptance and Florida Product Approval documentation. We provide the specific approval numbers that match your exact size, glass package, and frame material on your quote, so your permit submittal is straightforward.
FBC / HVHZ Compliance
These windows are engineered to Florida Building Code High-Velocity Hurricane Zone requirements, the standard that governs coastal Palm Beach construction. That’s not a design option; it’s the baseline for any impact window we put into an HVHZ address.
TAS 201 / TAS 202 / TAS 203 Testing Context
HVHZ-rated windows in Florida are tested under TAS 201 (large-missile impact), TAS 202 (cyclic wind-pressure loading), and TAS 203 (forced-entry resistance). These are the protocols the product family must pass to earn the approvals referenced above.
Design Pressure for Your Wind Zone
Design pressure is a PSF structural rating, not a wind speed, and we match it to your specific wind zone rather than slapping a maximum on every job. Design pressures go up to +/-100 PSF, matched to where in Palm Beach County the house actually sits.
Energy Performance
Low-E and insulated glass options are available for these 3-Panel Sliding windows when you want to cut solar gain on east- and west-facing Palm Beach walls. The coatings do their work without changing the impact rating of the laminated glass package.
Color & Glass Options
The 3-Panel Sliding (3-Lite Roller) window comes in five finish options: white, almond, bronze, black, and tan. In Palm Beach, FL, we see a lot of white and almond on older condos and ranch homes where the window needs to blend with stucco and existing trim. Bronze and black read more sharply on contemporary new builds and on houses with dark roofs or metal accents. Tan suits the softer palette of Mediterranean and Spanish-style homes across West Palm Beach and Lake Worth. The finish you choose is a powder-coated or factory-applied color on the frame, not a painted afterthought, so it’s consistent across the extruded aluminum profiles.
Glass choice comes down to three decisions. Clear laminated impact glass is the workhorse: maximum natural light, full impact rating. Tinted laminated glass reduces glare and solar gain, which matters on Palm Beach’s direct afternoon sun. Low-E insulated laminated glass adds a thermal break, which helps when the window faces a bedroom or a room you actually occupy all day. If you’re unsure which glass suits the orientation, we’ll point it out during the on-site measurement and put the recommendation on your quote.
Installation by Winslow Windows & Doors in Palm Beach
A Miami-Dade NOA-rated window is only as good as the opening it’s set into. We follow AAMA 2400/2410 installation practice on every 3-Panel Sliding (3-Lite Roller) window we install in Palm Beach, FL, because the approval assumes the window is installed to that standard. The process starts with a pre-install inspection: we pull the interior trim or measure the rough opening, check the buck, the condition of the surrounding substrate, and the actual wind zone at your address. Then we set the frame level, plumb, and square, not just close to it. A three-lite roller system that’s even slightly racked will bind, and a binding panel is the first sign of a sloppy job.
We seal the perimeter with AAMA 812 low-expansion foam, run the approved sealant lines, and re-check the opening before we hang panels. After the window is in, we water-test the sill and perimeter and run the panels through their full travel. Cleanup happens the same day. If your municipality requires a permit with a Florida Product Approval or NOA submittal, we handle that paperwork and coordinate inspections. Along the coast in Palm Beach and Jupiter, the wind-zone ratings and permitting expectations are strict; if the window wasn’t installed to the approved method, the NOA means nothing. That’s why we install what we sell, and why we don’t hand the window off to whoever answers the phone. Call (561) 831-7863 and we’ll walk your project before we ever write a quote.
Frequently Asked Questions - 3-Panel Sliding (3-Lite Roller) Windows

Most Palm Beach County municipalities want the Florida Product Approval or Miami-Dade NOA documents attached to the permit application when the work involves impact windows. We assemble the approval package for the exact configuration you ordered and submit it with the permit paperwork.
Yes within the tested size ranges for the approval. The two operable / one fixed and one operable / two fixed configurations both have working panel size limits, and we’ll confirm what’s achievable for your rough opening before we finalize the order. Call (561) 831-7863 to discuss your specific opening.
Keep the bottom track clear of sand and debris, especially during Palm Beach’s windy months, and wipe down the rollers with a dry cloth. An annual cleaning of the frame and a light silicone spray on the track are all most of these windows want. The glass cleans like any other window.
