After3-Panel Sliding (3-Lite Roller) Windows in Boca Raton, FL
A 3-panel sliding window – also called a 3-lite roller – gives you a wider opening than a standard two-panel unit while keeping the same slim frame profile. Two fixed outer panels flank a center sash that glides on a roller track, so you get ventilation across a broad span without swinging any hardware into the room or out toward your patio. For Boca Raton homes where wide wall openings face a pool deck, a garden, or an east-facing breeze off the Intracoastal, that combination of wide glass and easy operation is hard to beat.
At Winslow Windows & Doors, Ed Winslow has been providing our Window Installation services in Boca Raton since 2011. We’re locally owned, owner-operated, and authorized to install impact-rated 3-lite rollers from brands like PGT and ECO Window Systems – two lines that meet South Florida’s strict Miami-Dade Notice of Acceptance (NOA) requirements for wind and impact resistance. If you’ve already pulled quotes from someone else and want a second set of eyes on the numbers, call us at (561) 816-5648 – a live person will pick up, any time of day or night, and a free second opinion on any written estimate is always part of what we offer.
This page sits under our broader Window Installation in Boca Raton service, so if you’re replacing multiple window styles across your home, that’s a good place to start before coming back here for the specifics on 3-panel sliders.
When You Need 3-Panel Sliding (3-Lite Roller) Windows
Not every home needs this format, but when the situation calls for one, nothing else quite fits. Here are the scenarios we see most often in Boca Raton:
- Wide openings above kitchen sinks or countertops. A 3-lite roller spans widths that a single-hung or casement unit can’t cover without adding a center mullion that blocks your view. In the Boca country-club neighborhoods west of Military Trail, kitchens often open to covered patios – and a 72-inch or wider 3-panel slider fits those rough openings cleanly.
- Aging aluminum single-pane sliders that fog, leak, or jam. A lot of original construction in Camino Gardens, Royal Palm Yacht & Country Club, and similar established Boca neighborhoods used single-pane aluminum sliders from the 1970s and 1980s. Those tracks corrode, the rollers flatten, and the frames let in heat and humidity year-round.
- Hurricane code upgrades ahead of a re-roofing permit or home sale. Palm Beach County requires impact-rated glazing or approved storm shutters on any window that’s part of a permitted project. If you’re already pulling a roofing permit, upgrading to impact 3-lite rollers at the same time keeps your inspection timeline clean.
- High-humidity rooms like laundry rooms, bathrooms, or Florida rooms. A sliding sash doesn’t have exposed hinges or cranks to corrode in a salt-air environment – a real advantage when you’re three miles from the Atlantic and your windows face the prevailing southeast wind.
- Second-floor bedrooms where an outward-swinging casement is impractical. In two-story homes along A1A and in the Boca Teeca area, a 3-panel slider gives you ventilation control without risking a casement sash catching the wind and pulling away from the operator.
- Open-plan living areas where you want the glass, not the frame. The fixed outer panels of a 3-lite roller mean a large, uninterrupted glass area – good for daylighting and views – while the sliding center sash provides the airflow you need on Boca’s cooler winter evenings.
Our 3-Panel Sliding (3-Lite Roller) Windows Process
We don’t hand you a contract and disappear. Here’s exactly what happens from the first call to the final walk-through:
- Free on-site measure and estimate. Ed or one of our background-checked, uniformed technicians comes to your Boca Raton home, measures every opening precisely, checks the rough opening condition, and gives you a written, itemized quote before anyone touches a tool. No trip charge inside Palm Beach County. Upfront pricing – what the estimate says is what the invoice says.
- Product selection and permit coordination. We walk you through the 3-panel slider options that carry a Miami-Dade NOA, confirm the frame color, glass type (low-e, laminated impact, or both), and handle the Palm Beach County building permit application on your behalf. Most homeowners in Boca don’t realize the permit is the installer’s responsibility – we make sure it’s pulled correctly so your project doesn’t stall at inspection.
- Factory order and scheduling. Impact-rated 3-lite rollers are typically built to the specific rough-opening size, not pulled off a shelf. Lead times from brands like PGT and ECO Window Systems currently run two to six weeks depending on glass specification – we give you a realistic window (no pun intended) the day you sign, not the day before installation.
- Installation day. Our uniformed crew arrives in the scheduled window, removes the old unit carefully to avoid stucco or drywall damage, sets the new frame in the rough opening, levels and shims, applies the required sealant at the perimeter, and installs the sash and rollers. We test the slide, the lock engagement, and the weep system before we leave the room.
- Inspection and sign-off. Palm Beach County requires a final inspection for permitted window replacements. We coordinate the inspection appointment so you don’t have to take another half-day off work chasing a building department callback. Our work is done right the first time – that’s the standard behind the 36500-Day Done Right Promise – so we’re not worried about re-inspections.
- Final walk-through and cleanup. Before we pull the truck out of your driveway, we walk every installed window with you, demonstrate the roller lock and sash operation, confirm the weep holes are clear, and leave your home as clean as we found it. If anything isn’t right, we make it right – full stop.
3-Panel Sliding (3-Lite Roller) Windows Pricing in Boca Raton
In the Boca Raton market, installed 3-panel sliding windows typically fall between $850 and $2,400 per unit, depending on size, glass specification, and frame material. That range is wider than a single-hung replacement because 3-lite rollers come in substantially different widths – a 48-inch unit and a 96-inch unit are very different jobs. Below is a more granular breakdown:
| Window Width | Standard Glass (non-impact) | Impact-Laminated Glass (NOA-rated) |
|---|---|---|
| Up to 48 inches | $850 – $1,100 | $1,100 – $1,450 |
| 49 – 72 inches | $1,000 – $1,350 | $1,350 – $1,800 |
| 73 – 96 inches | $1,200 – $1,600 | $1,650 – $2,400 |
What moves the price:
- Impact vs. non-impact glass. Impact-laminated units cost more upfront but eliminate the need for storm shutters – a real factor in Boca Raton homes where shutter storage is limited or where HOA rules restrict accordion shutters on street-facing elevations.
- Frame condition and rough opening work. If the existing rough opening has rot, corroded framing, or is out of square, we’ll call it out before we install and price the repair separately – not after the fact.
- Low-e glass upgrades. Adding a low-e coating to impact glass is typically an additional $80-$140 per unit in our current Boca market. Given that south and west-facing rooms in Boca Raton can see interior temperatures spike 8-12 degrees from solar gain, it’s usually worth the addition.
- Permit fees. Palm Beach County building permit fees vary by project value, but for a typical 3-lite roller replacement they run $75-$175 per window. We include permit fees in your estimate – no surprise line item at sign-off.
- Quantity discounts. Replacing three or more windows in a single visit lowers per-unit labor cost meaningfully. We’ll reflect that in the written estimate.
Seniors and veterans receive a permanent 10% discount on all installations – no expiration date, no fine print. If you have a written estimate from another contractor, we’ll review it at no charge and give you our honest take on whether the scope and pricing are fair.

FAQs – 3-Panel Sliding (3-Lite Roller) Windows in Boca Raton
Do 3-panel sliding windows meet Palm Beach County’s hurricane code requirements?
Impact-rated 3-panel sliding windows that carry a Miami-Dade Notice of Acceptance (NOA) meet Palm Beach County’s current wind-borne debris requirements for the Boca Raton area, which sits in the High Velocity Hurricane Zone (HVHZ) along its eastern corridor. Non-impact sliders require an approved supplemental shutter system to satisfy the code. We install NOA-rated units from PGT and ECO Window Systems, and we pull the permit so the compliance documentation is on file with the county under your address. Call (561) 816-5648 and we’ll confirm exactly which specification applies to your home’s wind zone and elevation.
How much does a 3-panel sliding window installation cost in Boca Raton?
Installed 3-lite roller windows in Boca Raton typically run $850 to $2,400 per unit, with the spread driven primarily by width and glass type. A standard 48-inch non-impact unit starts around $850 installed; a 96-inch impact-laminated unit with low-e glass can reach $2,400 or more. Permit fees, rough-opening repairs, and quantity factors all affect the final number. The most accurate way to know your cost is a free on-site measure – call (561) 816-5648 and we’ll schedule one at no charge, with no trip fee inside Palm Beach County.
How long does a 3-panel sliding window installation take, and will I need to be home all day?
A single 3-panel sliding window replacement takes two to four hours from removal to final walk-through, depending on the size of the unit and the condition of the existing frame. Multi-window projects are typically completed in one visit. We give you a specific arrival window, not an all-day waiting span, and we’ll call you 30 minutes before the crew arrives. If your schedule is tight, Ed can talk through realistic timelines before you book.
Can you replace just one 3-lite roller in a home that still has original aluminum sliders?
Yes – we replace single units all the time. That said, if the rest of your original aluminum sliders are nearing end of life, it’s worth knowing that mixing old single-pane frames with a new impact unit can create an obvious visual mismatch and won’t bring the rest of the home into hurricane compliance. We’ll give you an honest assessment of the condition of your existing windows during the estimate visit – no pressure to replace more than you need, but full transparency about what you’re working with. Call (561) 816-5648 to schedule that conversation.
Why Boca Raton Homeowners Choose Winslow Windows & Doors
Ed Winslow started this company in 2011 because he saw how many Boca Raton homeowners were getting burned by installers who disappeared after the deposit cleared. His name is on the door – and on every job we do. That’s not a marketing line; it means if something isn’t right six months after installation, you call the same number, the same person answers, and we come back. The 36500-Day Done Right Promise is as literal as it sounds.
We’re not a franchise call center that routes your job to whoever is available that week. Our technicians are background-checked, show up in uniform, and have been doing this work in South Florida long enough to know that a Boca Raton home three streets from the Intracoastal needs different sealant choices than a home in western Boca near Glades Road – because salt air, sun angle, and drainage exposure are not the same across this city. That kind of local knowledge doesn’t come from a training manual.
As an authorized installer for PGT and ECO Window Systems, among others, we have direct relationships with the manufacturers whose products we put in your home. That matters when you need a warranty honored or a replacement sash two years from now – we’re not a middleman who’s already moved on to the next market.
