3-Panel Sliding (3-Lite Roller) Windows

3-Panel Sliding (3-Lite Roller) Windows in Westgate, FL | Winslow Windows & Doors

A 3-panel sliding window, also called a 3-lite roller, is the go-to configuration when you want an unobstructed wide opening with hurricane-rated glass in every panel. These windows put three panels on a shared horizontal track, with either one or two panels that glide open and the remaining panel or panels fixed in place. They’re a natural fit for Westgate homes where big openings face the pool, patio, or backyard slab, and where Florida’s wind codes demand more than a decorative window. Winslow Windows & Doors sells and installs these in aluminum and vinyl across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, sized and spec’d for your exact wind zone in Westgate.

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

The 3-panel sliding window is a horizontal roller configuration built for wider openings. Three lites sit in a shared frame, and laminated impact glass runs across all three panels, with PVB interlayer holding the glass in the frame under impact. One or two panels glide on the track while the rest stay fixed, so you get fresh air on demand and a full-width view when everything’s closed. In Westgate, where morning humidity and afternoon storms trade off through the wet season, this configuration earns its keep: you can open a panel for airflow when the weather’s good, then lock everything tight when a named storm rolls in without changing windows or wrestling with temporary panels.

The profile suits single-story ranchers and newer two-story builds equally well. We see it most often on openings from roughly 6 to 9 feet wide, where a two-panel slider would leave either a narrow operable panel or an awkward fixed lite. The third panel breaks that span into workable sections. The track sits low and clean in the frame, and panels ride on rollers that are sized for the weight of impact-rated glass, not a standard annealed lite. That matters in Westgate, because impact glass is heavy, and a track built for thin glass binds and drags within a season or two. We spec the hardware for the glass load, then install level, plumb, and square so the panel travel stays smooth year after year.

Technical Specifications

Here’s what’s available on this product line, in plain terms:

• Frame materials: Aluminum or vinyl, chosen for your opening and exposure in Westgate. Aluminum carries its strength in thinner lines; vinyl brings thermal performance. Both are available with this product profile.
• Track configurations: 3-lite with 2 fixed panels and 1 operable panel, or 3-lite with 1 fixed panel and 2 operable panels. We’ll walk you through which makes sense for where you want the air to come from.
• Glass options: Laminated impact glass with a PVB interlayer, Low-E insulated glass, tinted glass, and clear glass. Options can be combined where the build allows, so you can have impact resistance and energy performance in one unit.
• Finish options: White, almond, bronze, black, and tan. Finishes are available across the frame lines we carry, and we’ll match the exact finish name to the manufacturer you select.
• Screen options: Retractable screen or sliding screen. Both are spec’d to fit the 3-panel profile and clear the operable panels.
• Design pressure: Matched to your wind zone in Westgate, up to +/-100, never higher. We don’t oversell a DP rating, and we don’t under-spec one either.

Hurricane & Compliance Performance

Laminated Impact Glass
Every panel carries laminated impact glass, built with a PVB interlayer between the glass lites. When debris hits, the glass fractures but the interlayer holds the pieces in the frame. That keeps the window barrier intact until you replace the unit, which is the whole point of an impact-rated fenestration product in a Westgate home.

Miami-Dade NOA / Florida Product Approval
The configurations we sell and install carry Miami-Dade Notice of Acceptance numbers and Florida Product Approval numbers, issued per configuration. The exact numbers that apply to your opening size and panel setup get verified on your specific quote, not borrowed from a different product line or size.

FBC / HVHZ Compliance
These windows are engineered to Florida Building Code High-Velocity Hurricane Zone requirements. In practical terms, that means the frame, glass, hardware, and install method are all specified for the wind zone your Westgate address sits in, not a generic statewide minimum.

TAS 201 / TAS 202 / TAS 203 Testing Context
The HVHZ-rated product family here is tested under the TAS protocol: TAS 201 for large-missile impact, TAS 202 for cyclic wind-pressure loading, and TAS 203 for forced-entry resistance. Those tests simulate what a window actually endures during a storm, first the flying debris, then the repeated pressure cycles.

Design Pressure Matched to Your Wind Zone
We match design pressure to the wind zone, up to +/-100, never higher. A higher DP number is not a better window for you, it’s just a different test result. What you want is the correct DP for your opening and your Westgate location, and that’s exactly what we specify.

Energy Performance Options
Low-E and insulated glass options are available on this product, and they’re worth considering in Westgate even though impact compliance gets the attention. A Low-E coating knocks back radiant heat gain, and an insulated airspace improves the whole assembly’s thermal performance while the impact layer does its job.

Color & Glass Options

Color and glass choice depends on the house you have and the light you want inside it. White and almond are the workhorses in Westgate, disappearing into stucco walls and leaving the view as the focus. Bronze and black add contrast on coastal or Mediterranean elevations, and black frames in particular read current and crisp against lighter exterior paint. Tan sits between the two, and suits homes with natural stone or earthy palettes.

On the glass side, clear laminated impact glass gives you a true-to-life view and the impact layer you need for code. Tinted glass cuts glare and solar heat, and we see it requested most often on western and southern exposures in Westgate where the afternoon sun sits on the window. Low-E insulated glass is the smart pick for rooms that run hot in the summer, since the coating reflects radiant heat and the insulated airspace slows conductive transfer. You don’t have to choose between hurricane performance and energy efficiency; we can combine the impact layer with Low-E in one unit on most of our lines. Call (561) 468-6136 and we’ll bring finish samples and glass samples to your home in Westgate.

Installation by Winslow Windows & Doors in Westgate

A window that passes TAS 201 and TAS 202 on a test wall only performs to that rating when it’s installed right. That’s the part no spec sheet covers. We install per AAMA 2400/2410 practice, which means the opening gets prepped, the frame is set level, plumb, and square, and the anchor points follow the manufacturer’s approved schedule. We use AAMA 812 low-expansion foam perimeter sealant, which seals without bowing the frame or pushing it out of true. Then we flash, trim, and clean up, and we run a final water test before we call the job done.

Westgate-specific considerations matter on this product. Coastal exposure, even a half-mile inland, changes the wind zone and the DP requirement. The age of the house changes the opening tolerance we’re working with. The permitting jurisdiction changes what gets submitted. In HVHZ jurisdictions, the permit package has to reference the exact Miami-Dade NOA or Florida Product Approval numbers for your configuration, and we handle that verification as part of the quote so there are no surprises at plan review. Improper installation compromises the whole system. A gap in the perimeter seal, a racked frame, or missing anchors are enough to turn a rated window into an opening that leaks in a storm. We don’t let that happen. We measure, we spec, we install, and we stand behind the work. Call (561) 468-6136 to schedule a free on-site measurement in Westgate.
