3-Panel Sliding (3-Lite Roller) Windows in Palm Beach, FL

A 3-panel sliding window – sometimes called a 3-lite roller – gives you a wider opening than a standard two-panel unit by adding a fixed center lite flanked by two operable sliding panels. In Palm Beach, where wide ocean views and cross-breezes are part of why people live here, these windows are a natural fit for great rooms, master suites, and any wall where you want glass running from corner to corner. They’re also built to meet Florida’s strict impact and energy codes, so you’re not trading aesthetics for protection.

At Winslow Windows & Doors, Ed Winslow has been installing 3-lite rollers across Palm Beach since 2011. We’re locally owned, state-licensed, and authorized to install PGT and CGI units – two brands that set the standard for impact-rated sliding windows in South Florida. If you’re ready to talk options, call us at (561) 831-7863 – a live person answers every time, around the clock.

When You Need 3-Panel Sliding (3-Lite Roller) Windows

Not every home needs a 3-lite roller, but when the situation calls for one, nothing else really substitutes. Here’s when Palm Beach homeowners typically come to us for our Window Installation services with this specific request:

• You have a wide rough opening and want maximum glass. Older Palm Beach homes – particularly the Mediterranean and Mizner-influenced properties along South Ocean Boulevard and El Brillo Way – often have wide window bays designed for dramatic views. A 3-panel unit fills those openings without awkward dividers breaking up the sightline.
• You need ventilation on both sides of a fixed center panel. In Palm Beach’s humid subtropical climate, airflow management matters. A 3-lite roller lets you open both end panels simultaneously, pulling a cross-breeze through a room in a way a single slider simply can’t replicate.
• Your existing 3-lite unit is showing signs of seal failure. When the fixed center panel goes foggy or the rollers on the operable panels stick and grind, it’s usually faster and more cost-effective to replace the whole unit rather than chasing individual repairs on an aging frame.
• Hurricane season is coming and your current windows aren’t impact-rated. Palm Beach sits in a High-Velocity Hurricane Zone (HVHZ). Standard sliding windows won’t meet the code requirements that apply here. A new PGT or CGI 3-panel impact unit will, and it eliminates the annual scramble to install shutters.
• Your energy bills are climbing despite the A/C running constantly. Salt air and UV exposure degrade glazing faster in Palm Beach than inland markets. If your sliders are more than 12-15 years old, the thermal barrier is likely compromised – and replacing them with low-E laminated glass makes a measurable difference on your FPL bill.
• You’re doing a full exterior renovation and want cohesive framing. If you’re updating the facade of a Palm Beach estate or a North End bungalow, mismatched window sizes undercut the finished look. A custom-sized 3-lite roller can be ordered to match existing frame dimensions precisely, so the new windows don’t fight the architecture.

Our 3-Panel Sliding (3-Lite Roller) Windows Process

Every installation follows the same sequence – no shortcuts, no subcontracted strangers showing up unannounced. Here’s what working with Winslow looks like from the first call to the final walkthrough:

1. Free in-home measurement and consultation. Ed or one of our background-checked, uniformed technicians visits the property, takes precise rough-opening measurements, and walks you through the unit options that fit both your opening and your budget. We don’t charge a trip fee for homes in Palm Beach County. We come prepared with product samples and spec sheets for the brands we carry, so you can see the frame profiles and glass options in person – not just on a website.
2. Upfront written quote – no surprises. Before we order anything, you get a written line-item estimate. That number doesn’t change unless you change the scope. Pricing covers the unit, hardware, installation labor, disposal of the old window, and any required permitting fees. Nothing is buried in fine print.
3. Permit pull and HVHZ compliance check. In Palm Beach, 3-lite impact windows require a building permit and must be installed per Florida Building Code Chapter 16 wind-load requirements for the HVHZ designation. We handle the permit pull and make sure every unit we install carries the correct NOA (Notice of Acceptance) for Palm Beach County. This protects your homeowner’s insurance coverage and your resale value – buyers’ attorneys check for open permits.
4. Scheduled installation with your uniformed crew. We give you a specific arrival window, not a four-hour “sometime in the morning” guess. The crew arrives in Winslow-branded vehicles, in uniform, and carries ID. You’ll know exactly who’s on your property before anyone rings the bell.
5. Full installation, seal, and test. The old unit comes out carefully – we protect surrounding finishes and don’t gouge stucco frames. The new 3-lite roller goes in, is shimmed level, sealed against water intrusion (critical in Palm Beach’s driving-rain season), and tested for smooth panel operation, proper latch engagement, and a tight weather seal on both operable panels.
6. Cleanup and final walkthrough. We clean up completely and walk you through the finished installation before we leave. If anything isn’t exactly right, we fix it on the spot. That’s not a policy slogan – it’s the 36500-Day Done Right Promise. If a problem surfaces later, we come back. No expiration date, no debate.

3-Panel Sliding (3-Lite Roller) Windows Pricing in Palm Beach

3-panel sliding windows in Palm Beach typically run between $1,100 and $3,400 per unit installed, depending on size, glass specification, and frame material. That’s a wide range, so here’s what actually moves the needle on price:

Most single-story Palm Beach homes replacing an existing 3-lite unit land in the $1,400 to $2,100 range per window for a mid-size opening with standard impact laminated glass in an aluminum frame. If you’re specifying a PGT WinGuard or CGI Guardian unit with upgraded low-E glass for one of the larger openings common in the Estate Section, expect $2,400 to $3,200 installed.

A few things that can add cost and are worth knowing upfront:

• Second-story installations require different rigging and typically add $150-$300 per unit.
• If the existing opening needs to be widened or the rough opening requires structural work, that’s a separate line item – we’ll tell you before we start.
• Homes in Palm Beach’s historic districts may have additional review requirements before permits are issued. We’re familiar with the process and factor it into your timeline.

Seniors and veterans receive a permanent 10% discount on every job – no expiration, no enrollment required, just mention it when you call. We also take $40 off any repair over $200, and if you’ve already got a written estimate from another company, we’ll give you a free second opinion before you sign anything.

FAQs – 3-Panel Sliding (3-Lite Roller) Windows

How much do 3-panel sliding windows cost in Palm Beach?

In Palm Beach, 3-panel sliding windows typically cost between $1,100 and $3,400 per unit fully installed, with most standard residential replacements landing between $1,400 and $2,100. The biggest variables are the width of the opening, the glass specification (standard impact laminated vs. low-E), and whether any structural work is needed around the opening. Call (561) 831-7863 for a free in-home estimate – we measure the opening, walk you through the options, and give you a written price before anything is ordered.

Do 3-lite roller windows meet Palm Beach’s hurricane impact requirements?

Yes – when properly specified and installed. Palm Beach falls within Florida’s High-Velocity Hurricane Zone, which means impact windows must carry a valid NOA (Notice of Acceptance) for that designation and be installed per Florida Building Code wind-load requirements. The PGT WinGuard and CGI Guardian units we install are rated for HVHZ conditions. We also pull the required building permit on every job, which confirms compliance and protects your insurance and resale value. A window that’s merely “impact-resistant” but lacks the correct NOA for HVHZ won’t pass Palm Beach County inspection.

Can you replace just the sliding panels on an existing 3-lite unit, or does the whole frame need to come out?

In some cases, individual panels can be replaced if the frame is structurally sound, the frame profile matches a current product line, and the seal between the frame and the rough opening is still intact. In practice, frames on Palm Beach homes more than 10-15 years old have usually been compromised by salt air and UV degradation to the point where full-unit replacement is the more cost-effective path – especially since a full swap qualifies for the current impact-rating standards and resets your warranty clock. We’ll assess the existing frame during the free estimate and give you an honest recommendation. If a panel swap is the right call, we’ll say so.

How long does a 3-panel sliding window installation take in Palm Beach?

A standard same-size replacement of a single 3-lite unit typically takes three to five hours on-site for an experienced crew. Multiple-unit projects are usually completed in one day. The longer lead time is on the front end: permit processing in Palm Beach County and product lead times from PGT or CGI can run two to six weeks depending on unit specifications and current order volumes. We give you a realistic timeline at the estimate stage – not an optimistic one designed to get you to sign, and then a string of delays.

What’s the difference between a 3-panel sliding window and a standard two-panel slider?

Unlike Casement Windows, a standard two-panel slider has one fixed panel and one operable panel – you get ventilation from one side of the opening. A 3-lite roller adds a fixed center panel with operable panels on both sides, which means you can open both ends simultaneously for better cross-ventilation, and the overall glass area is significantly larger. For wide openings – typical in Palm Beach’s larger homes – a 3-lite unit also distributes the weight of the glass more evenly across the frame, which matters for structural integrity in a hurricane zone. The tradeoff is a slightly narrower individual vent opening on each side compared to a two-panel unit of similar overall width.

Why Palm Beach Homeowners Call Winslow First

Palm Beach is a specific market. The salt air off the Atlantic accelerates frame corrosion. The HVHZ designation means impact compliance isn’t optional. Historic district rules add a layer of review that trips up contractors who don’t work here regularly. And the homes themselves – from the mid-century moderns near Barton Avenue to the Addison Mizner-era estates along the waterfront – often have non-standard opening dimensions that require a product line flexible enough to accommodate them, whether that’s Awning & Hopper Windows or other styles.

Ed Winslow has been working in Palm Beach since Winslow Windows & Doors opened in 2011. He knows which permit reviewers to call when a question comes up, which CGI and PGT product lines come in the frame widths common in Palm Beach’s estate-size openings, and which neighborhoods have HOA aesthetic requirements that affect frame color selection. That’s not something you get from a national chain that assigned your job to a regional dispatcher.

Every technician we send to your home is background-checked and arrives in uniform. You know who’s coming before the truck pulls up. Pricing is written and fixed before we order anything. And if something isn’t right after installation – a panel that doesn’t roll smoothly, a seal that develops a gap – the 36500-Day Done Right Promise means we come back and fix it. Not someday. Not after three phone calls. We fix it.

Ed’s name is on the business. That means every job in Palm Beach carries his personal accountability.
