After3-Panel Sliding (3-Lite Roller) Windows in Palm Beach, FL
A 3-panel sliding window – sometimes called a 3-lite roller – gives you a wide, uninterrupted glass opening by using three side-by-side panels where the outer two are fixed and the center panel slides open. In Palm Beach, where salt air, hurricane-season pressure loads, and strict Miami-Dade and Palm Beach County building codes all factor into every window decision, getting the right unit installed through our Window Installation services by someone who knows the local requirements matters more than most homeowners realize. Call us at (561) 782-7525 and a live person will pick up – day or night – to talk through what your home actually needs.
At Winslow Windows & Doors, Ed Winslow has been fitting 3-lite rollers and full window systems across Palm Beach since 2011. As an authorized installer for brands like PGT and ViewLux, we spec impact-rated units that meet Florida Product Approval requirements, handle every permit pull, and back the finished job with our Done Right Promise – if it’s not right, we come back and make it right. No qualifier, no expiration date on that promise.
If you’re weighing your full window replacement project at the same time, our Window Installation in Palm Beach page walks through every window type and configuration we handle for Palm Beach homeowners.
When You Need 3-Panel Sliding (3-Lite Roller) Windows
Not every home or every opening is a candidate for Awning & Hopper Windows or a 3-lite roller – but when the fit is right, there’s no better window for maximizing glass area and ventilation in a single rough opening. Here are the situations we see most often in Palm Beach:
- Wide openings that standard double-hungs won’t cover. In older Palm Beach homes along the Lake Worth Lagoon or in the South End, it’s common to find horizontal rough openings 6 to 10 feet wide. A 3-panel slider fills that space cleanly with one unit instead of a clunky bank of individual windows.
- Living rooms and great rooms facing the water or a pool deck. Homeowners on Flagler Drive or near the Intracoastal want the widest possible glass plane without a center meeting rail breaking the view. A 3-lite roller’s fixed outer panels keep the sightline clean while the center panel slides for airflow.
- Roller windows that have been stuck, leaky, or drafty for years. Palm Beach’s salt-heavy air eats aluminum tracks. If your existing slider drags, rattles in a storm, or lets in humidity even when closed, the weatherstripping and rollers are likely gone – and in most cases a full unit replacement is more cost-effective than chasing repairs on a 15-year-old frame.
- Hurricane season prep or insurance compliance upgrades. Florida’s wind-borne debris region requirements cover all of Palm Beach. If your current windows aren’t impact-rated or don’t carry a current Florida Product Approval number, your insurer may be applying surcharges – or your coverage may have gaps you don’t know about yet. A properly installed impact 3-lite roller solves both problems.
- Remodels where natural light is the priority. Kitchen additions, sunrooms, and rear-facing great rooms in neighborhoods like Palm Beach Shores and El Cid routinely spec 3-panel sliders because the fixed outer panes dramatically increase glass area compared to a single slider of the same width.
- Existing single-slider replacement with a code-compliant upgrade. Single-panel sliders don’t satisfy current Palm Beach County energy compliance in all configurations. Upgrading to a low-E, impact-rated 3-lite unit often brings the opening into full compliance in one step.
Our 3-Panel Sliding (3-Lite Roller) Windows Process
We’ve installed enough windows in Palm Beach to know that the process matters as much as the product. Here’s exactly what happens when you call us:
- Free in-home measurement and consultation. Ed or one of our background-checked, uniformed technicians visits the home, measures the rough opening precisely, checks the surrounding framing for rot or moisture damage (a real concern in Palm Beach’s coastal humidity), and confirms which Florida Product Approval numbers apply to the unit we’re recommending. You get upfront pricing before we leave – no estimate that balloons at install.
- Product selection and permit filing. We’ll spec the right 3-lite roller for your opening – commonly a PGT WinGuard or ViewLux impact series unit depending on your frame material, glass package preference, and budget. Then we pull the Palm Beach County building permit. We handle the paperwork; you don’t have to navigate the county portal.
- Old unit removal. On install day, our crew removes the existing window cleanly, protecting your interior finishes and landscaping. We inspect the buck and sill for deterioration at this stage – if we find surprises, we show you before we proceed, not after.
- Impact window installation and sealing. The new 3-panel unit is set, shimmed, fastened to spec, and sealed with a Florida-code-approved sealant system. For impact units in Palm Beach’s coastal zone, proper sealant application isn’t optional – it’s part of what determines whether the window holds in a Category 3 storm.
- Inspection coordination. Palm Beach County requires a building inspection on permitted window installations. We schedule it, meet the inspector, and make sure the job passes. If a reinspection is ever needed, that’s on us – the Done Right Promise covers it.
- Final walkthrough and roller adjustment. Before we leave, we walk you through operation of the sliding panel, confirm the latch engages correctly, and adjust the rollers so the center panel glides smoothly. A 3-lite roller that drags on day one is a roller that fails in three years.
3-Panel Sliding (3-Lite Roller) Windows Pricing in Palm Beach
3-panel sliding windows in Palm Beach typically run between $850 and $2,800 per unit installed, depending on size, glass package, frame material, and whether the opening needs any structural prep work. That range is wider than a single-slider because 3-lite rollers cover a bigger span of opening widths – a 6-foot unit and a 10-foot unit are very different jobs.
| Configuration | Typical Installed Price (Palm Beach Market) |
|---|---|
| Standard impact 3-lite roller, 60″-72″ wide, clear glass | $850 - $1,300 |
| Impact 3-lite roller, 72″-96″ wide, low-E glass | $1,200 - $1,800 |
| Large-format impact 3-lite roller, 96″-120″ wide | $1,700 - $2,400 |
| Oversized or custom unit with specialty glass (tinted, laminated upgrades) | $2,200 - $2,800+ |
| Buck/frame repair or structural prep (when needed) | $150 - $600 additional |
A few things that move the number in Palm Beach specifically:
- Salt-zone requirements. Homes within a certain distance of the Atlantic or the Intracoastal face stricter corrosion-resistance specs. The hardware and frame coatings on a coastal-zone unit cost more than a standard unit – but skipping that spec on a Palm Beach home is a mistake that shows up fast.
- Existing frame condition. Older stucco homes in the historic Palm Beach district often have deteriorated wood bucks behind the original aluminum frames. We find this, tell you, and give you a number before we proceed – not after.
- Permit fees. Palm Beach County permit fees for window replacement vary by project valuation. We include permit costs in our upfront quote so the invoice matches what we told you at the start.
- Glass package. Low-E coatings and laminate upgrades add cost but often pay back through lower cooling bills – Palm Beach averages over 240 days of sunshine annually, and east-facing rooms can see significant heat gain through standard glass.
Seniors and veterans receive a permanent 10% discount on all work – no expiration, no special code needed. And if you have a written estimate from another company, we’ll give you a free second opinion so you can make a fully informed call.

FAQs – 3-Panel Sliding (3-Lite Roller) Windows
What’s the difference between a 3-panel sliding window and a regular single slider?
A 3-panel sliding window has three panes – two fixed outer panels and one center panel that slides open – while a standard single slider typically has one fixed panel and one moving panel. The 3-lite configuration gives you significantly more fixed glass area, which means better views and more daylight, but ventilation is limited to the center panel’s opening. For wide openings in Palm Beach homes facing the water or a pool deck, the tradeoff is usually worth it. Call us at (561) 782-7525 and we can walk you through whether a 3-lite roller or Bay & Bow Windows makes more sense for your specific opening.
Do 3-panel sliding windows in Palm Beach need to be impact-rated?
Yes – all of Palm Beach County falls within Florida’s wind-borne debris region, which means windows must either be impact-rated (laminated glass with a reinforced frame) or paired with a code-approved exterior shutter system. For most Palm Beach homeowners, Casement Windows or an impact 3-lite roller is the cleaner solution: no shutters to deploy before a storm, and the window itself carries the Florida Product Approval number your insurer and the county inspector want to see. We install impact-rated 3-lite rollers from PGT that meet those requirements. If you have questions about what your current windows do or don’t cover, call (561) 782-7525 – we’ll give you a straight answer.
How long does a 3-panel sliding window installation take in Palm Beach?
Most single-unit 3-lite roller replacements take four to six hours on install day, including removal of the old window, any minor framing prep, installation, sealing, and final roller adjustment. The permit process with Palm Beach County adds time on the front end – typically one to three weeks depending on current county volume – which is why we file the permit as soon as you’ve signed off on the quote. The county inspection after installation is usually scheduled within a week of completion. We coordinate all of it so you don’t have to track down the building department yourself.
Can a 3-panel sliding window be repaired, or does it need full replacement?
It depends on what’s failing. Worn rollers and damaged weatherstripping on a unit that’s otherwise structurally sound can often be repaired – and for jobs over $200, our standing $40 off repair discount applies. Cracked or broken impact glass, corroded frames, or a unit that no longer meets current Florida Product Approval standards typically points to full replacement. For impact glass specifically, a cracked laminated pane isn’t just a cosmetic issue – the unit has lost its rated protection until the glass is replaced. We’ll give you an honest assessment at the free estimate visit. Ed Winslow’s name is on this business, and we’re not going to recommend a $1,500 replacement when a $300 repair will actually solve the problem.
Why Palm Beach Homeowners Call Winslow Windows & Doors
Ed Winslow started this company in 2011 because he saw a gap: Palm Beach homeowners were getting big-box proposals from crews who didn’t know the local coastal codes, weren’t pulling proper permits, and disappeared after the check cleared. Fifteen years later, Winslow Windows & Doors is still locally owned, still operated by Ed, and still answering calls at 2 a.m. when something comes up before a named storm.
Our technicians are background-checked and show up in uniform. You know who’s at your door before the truck pulls in. Pricing is upfront – the number we give you at the estimate visit is the number on the invoice. And the Done Right Promise isn’t a marketing phrase: it means if a job we did isn’t right, we come back and fix it. No arguing about warranty terms, no “that’s not covered.” Ed’s word is the warranty.
We’re an authorized installer for PGT, CGI, and five other premium window brands. We pull our own permits, coordinate county inspections, and don’t subcontract the install to whoever’s available that week. The crew that quotes the job does the job.
For homeowners across Palm Beach – from the estates on South Ocean Boulevard to the mid-century homes near Worth Avenue – that’s the difference between a contractor and a neighbor you can actually count on. Our full home page covers everything we do, or you can go straight to our Window Installation in Palm Beach overview if you’re still figuring out which window type fits your project.
