3-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.

Reviews

What Neighbors Say About Winslow Windows & Doors

★★★★★

"Ed measured every opening himself and walked me through the product approval paperwork before I signed anything. When the inspector came he found the notice of acceptance taped inside a window like it should be and passed us first visit."

RRosalind Beaumont
★★★★★

"Our insurance agent asked for the wind mitigation paperwork and Ed had the whole file ready the day the job closed, every opening photographed. The premium conversation went very differently this year."

OOdessa Fairbanks
★★★★★

"The old aluminium sliders howled every afternoon storm and swelter came straight through the glass. The new impact sliders shut with a sound like a bank vault and the back rooms finally hold their temperature."

PPercival Whitcombe
★★★★★

"Someone tried the back slider while we were away. The glass crazed and held, the alarm never had to earn its keep, and the police report reads better than it might have. Ed came out the next morning to check the frame himself."

CCornelius Adeyemi
★★★★★

"We sat out a hurricane behind the windows Ed put in. The gusts threw a neighbour's trampoline down the street and the loudest thing in our house was the kettle. I rang him after to say thank you and he answered his own phone, same as always."

TThaddeus Okonkwo
★★★★★

"Three big companies quoted us and every one sent a salesman with a leased truck. Ed turned up in a truck with his own name on the door, quoted less, and his crew were the same faces on day one and day nine."
