After3-Panel Sliding (3-Lite Roller) Windows in Boca Raton, FL | Winslow Windows & Doors
Winslow Windows & Doors supplies and installs 3-panel sliding (3-lite roller) impact windows for Boca Raton homeowners who want an unbroken view with real hurricane protection. This configuration runs three lites of laminated impact glass on a horizontal track, giving you a wider opening than a typical two-panel slider without sacrificing code compliance. We’ve installed this profile across PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines throughout Boca Raton, from Royal Palm Yacht & Country Club to Mizner Park-adjacent condos. If you’re pricing a replacement or a new construction opening, call (561) 816-5648 and we’ll walk you through what’s realistic for your wind zone.
Product Overview - 3-Panel Sliding (3-Lite Roller) Windows
A 3-panel sliding window, sometimes called a 3-lite roller, puts three vertical glass panels in a single horizontal frame. On a wide living room wall or a master bedroom opening facing the water, that extra lite buys you a cleaner sightline than two oversized panels would. The panels glide on a track system – you choose whether one panel operates with two fixed, or two operate with one fixed, depending on how much ventilation you want and where furniture sits.
For Florida, the glass package matters more than the panel count. Every 3-lite roller we quote in Boca Raton uses laminated impact glass with a PVB interlayer. That’s the layer that holds glass shards in the frame when debris hits at speed. Combined with aluminum or vinyl framing engineered for High-Velocity Hurricane Zone conditions, the system is built to stay sealed during a storm, not just to survive the first impact. You get the horizontal glide of a sliding door, in a window format that’s rated for coastal wind loads. This configuration works especially well in mid-century ranch homes in Old Floresta, contemporary builds in Royal Palm, and condo replacements along A1A where the existing rough opening is wide but not tall enough for a door.

Hurricane & Compliance Performance
Laminated Impact Glass - Laminated impact glass with a PVB interlayer holds glass in the frame under impact. When debris strikes, the glass cracks but the interlayer keeps the pane intact, preventing wind and rain from entering your Boca Raton home through the breach.
Miami-Dade NOA / FL Product Approval - Miami-Dade NOA and Florida Product Approval numbers are issued per configuration, not as a blanket rating. Your specific panel configuration, frame material, and size get a matching approval number. We verify this on your written quote before you commit.
FBC / HVHZ Compliance - This window is engineered to Florida Building Code High-Velocity Hurricane Zone requirements. Boca Raton sits in an HVHZ jurisdiction, so anything less would fail permit review. We don’t sell non-HVHZ products into HVHZ applications.
TAS 201, 202, and 203 Testing Context - The test protocol family behind HVHZ-rated impact products includes TAS 201 for large-missile impact, TAS 202 for cyclic wind-pressure loading, and TAS 203 for forced-entry resistance. These are the standards that prove a window doesn’t just survive one hit, but keeps working under repeated pressure cycles.
Design Pressure for Your Wind Zone - Design pressures are matched to your wind zone, up to +/-100 PSF, and never higher. That means we don’t oversell you a rating you don’t need, and we don’t underspec a unit for a coastal exposure on the barrier island. Your quote lists the exact DP rating for your elevation and zone.
Energy Performance - Low-E and insulated glass options are available for energy performance. In Boca Raton’s climate, Low-E insulated units reduce solar heat gain through the glass while keeping the impact rating intact. Tinted glass is another option for east- and west-facing openings with direct sun.
Color & Glass Options
Finish selection in Boca Raton tends to follow the architecture. White and almond remain the most common choices for older concrete-block houses and condo replacements where the HOA has a posted palette. Bronze and black frames read well on contemporary builds and on homes with dark aluminum accents. Tan shows up most along the inland golf-course communities, where warmer exterior tones are common. Every finish is a factory-applied coating, not a field-painted surface, so it holds up to salt air without peeling.
On glass, clear laminated impact is the baseline. If energy performance matters, a Low-E insulated unit gives you impact protection plus reduced heat gain, which matters when your slider faces the afternoon sun. Tinted glass cuts glare and heat without the added weight of an insulated unit. For bedrooms, we often combine Low-E insulated with tinted for both thermal and light control. Whatever you choose, we order each configuration with its specific NOA or Florida Product Approval number, so the glass and frame stay matched.
Installation by Winslow Windows & Doors in Boca Raton
We start every 3-lite roller installation in Boca Raton with a pre-install inspection of the rough opening. That means checking the existing framing, confirming the actual measurements against the order, and verifying the sill is sound. If the opening has rot or settling, that gets addressed before a single window goes in. We don’t install new impact windows into bad framing.
Every unit we set is leveled, plumbed, and squared before fasteners go in. We follow AAMA 2400 and 2410 installation practice, and we use AAMA 812 low-expansion foam for the perimeter seal. That foam seals air and moisture without distorting the frame. After fastening and sealing, we run a water test on the installation and confirm the panels glide smoothly across the full track. Then we clean the job site down to the original condition.
One point we make clear to every Boca Raton customer: an impact window with a Miami-Dade NOA is only compliant if it’s installed correctly. A sloppy install voids the benefit of the approval, and a permit inspector will catch it. We know the permitting requirements in Boca Raton and Delray Beach and unincorporated Palm Beach County, including coastal exposure documentation. We handle the permit set and the installation in one pass, because the two aren’t separate jobs. They’re the same job done right.
Frequently Asked Questions - 3-Panel Sliding (3-Lite Roller) Windows
Design pressures are matched to your specific Boca Raton wind zone, up to +/-100 PSF, and never higher. Your quote will show the exact DP rating required for your elevation and distance from the coast. Call (561) 816-5648 with your address and we’ll confirm your zone before quoting.
Lead times vary by manufacturer and configuration, and custom sizes always run longer than stock sizes. If your project is permit-driven, we’ll order as soon as your drawings are finalized so the windows arrive when the opening is ready. Call (561) 816-5648 and we’ll give you a current timeline for the line you’re interested in.
Yes. Every configuration carries a Miami-Dade NOA and Florida Product Approval number specific to that size, frame material, and panel arrangement. We pull that documentation and include it with your permit package in Boca Raton. If you’re working with a contractor, we’ll coordinate the submittal directly. Call (561) 816-5648 for help matching the right approval to your opening.
You can choose between a 2-fixed/1-operable layout or a 1-fixed/2-operable layout, and the rough opening is built to your wall dimensions within the tested size range for the line you select. Custom sizing is common on replacement work in Boca Raton, where original openings are rarely square to modern standard sizes. Call (561) 816-5648 with your rough opening dimensions and we’ll tell you what’s feasible.
Keep the bottom track clear of sand and debris, especially after storms or beach outings. Rinse the track with water and wipe the frame with mild soap and water. Lubricate the rollers annually. Don’t use harsh solvents on the finish. If you notice drag or binding, call us at (561) 816-5648 before forcing the panel, because a bent track or worn roller is a cheap fix when caught early.
