After3-Panel Sliding (3-Lite Roller) Windows in Palm Beach, FL | Winslow Windows & Doors
3-Panel Sliding (3-Lite Roller) Windows give Palm Beach homeowners a practical way to put a wide, uninterrupted view where a single or double window won’t do. These units pair laminated impact glass across all three lites with smooth multi-panel gliding, so you get hurricane-rated protection without sacrificing natural light or easy airflow. Palm Beach’s wind zone and proximity to the Atlantic make impact-rated glazing a requirement on many replacement jobs, and Winslow Windows & Doors installs these windows across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines. Call (561) 782-7525 to discuss your opening size and schedule a free on-site measurement.
Product Overview - 3-Panel Sliding (3-Lite Roller) Windows
A 3-Panel Sliding (3-Lite Roller) Window is essentially three vertical glass panels set in a single frame, with one or two of the panels gliding horizontally on roller carriages. The configuration lets you span a wider rough opening than a typical two-panel slider while keeping sightlines clean. In Palm Beach, where coastal modern and Mediterranean styles often call for broad glass runs facing the water or pool, this profile shows up in living rooms, dining areas, and primary suites.
What separates an impact-rated 3-lite roller from a standard sliding window is what’s behind the glass. Each lite carries a PVB interlayer bonded inside the laminate. When a windborne object strikes, the glass may crack but the interlayer holds the broken pieces in the frame. That’s the behavior Miami-Dade testing is designed to verify, and it’s the reason these windows don’t require shutters in most HVHZ jurisdictions.
Aluminum and vinyl are the two frame materials you’ll see on this product. Aluminum offers narrow profiles and a more architectural look that suits a lot of Palm Beach construction. Vinyl brings thermal separation and tends to feel quieter in coastal settings where salt air is a factor. Winslow Windows & Doors has installed both materials in Palm Beach homes from Northwood to South End, and we can walk you through which makes sense for your wall depth and style.

Hurricane & Compliance Performance
Laminated Impact Glass
The PVB interlayer is what does the work in a storm. Under impact, glass fragments stay adhered to the interlayer rather than entering your home. This is the same protective mechanism tested in Miami-Dade’s large-missile protocol. Fine print: no, we do not publish a mph rating here; the rating is expressed by your wind zone on a project-specific basis.
Miami-Dade NOA / Florida Product Approval
Every configuration carries its own NOA and Florida Product Approval number. These are issued per size, frame, and glass combination, which is why we verify the specific approval on your written quote. If your Palm Beach building department asks for it, we provide the correct submittal for your permit.
FBC / HVHZ Compliance
These windows are engineered to the Florida Building Code’s High-Velocity Hurricane Zone requirements. Palm Beach sits inside the HVHZ map, which means windborne-debris protection is a code mandate, not a preference. The product is built for that jurisdiction.
TAS 201 / 202 / 203 Testing Context
The protocol family includes large-missile impact (TAS 201), cyclic wind-pressure loading (TAS 202), and forced-entry resistance (TAS 203). These are the tests HVHZ-rated products are certified under. Any NOA you pull for this window will reference these standards.
Design Pressure for Your Wind Zone
The design pressure on any unit is matched to the wind zone of the specific Palm Beach address. We will not sell you a window rated higher than your structure requires, nor one rated lower. Up to +/-100 is the ceiling here, not the target. Your opening’s size and exposure drive the calculation.
Energy Performance
Low-E and insulated glass options are available for homeowners who want more than impact protection. In Palm Beach, Low-E helps with solar heat gain on west-facing rooms, while insulated glass supports homes running AC most of the year. Tinted glass solves glare on bright waterfront elevations.
Color & Glass Options
White and almond remain the workhorses for Palm Beach’s Mediterranean and Spanish Revival homes, where casings and sills are often painted. Bronze and black read more contemporary and suit new coastal modern builds from El Cid to Palm Beach Gardens. Tan bridges the two, pairing well with stucco in sandy tones for houses that want warmth without strong contrast.
On the glass side, laminated impact glass is the base requirement for HVHZ compliance. Low-E insulated glass enhances it. Tinted glass is popular on Palm Beach rooms with direct eastern or western exposure where glare off the Intracoastal is relentless. Clear glass is available when the goal is maximum transmission and you’re handling solar gain through window coverings instead.
Installation by Winslow Windows & Doors in Palm Beach
The best engineered impact window becomes a liability if the installation is sloppy. In Palm Beach, where wind-driven rain and coastal exposure are part of the deal, the interface between the frame and the rough opening is where water gets in. That’s why Winslow Windows & Doors installs every 3-Panel Sliding (3-Lite Roller) Window with the same discipline on every job.
We start with a pre-install inspection of the opening, checking for rot, out-of-square framing, and water intrusion history before the old window comes out. The unit is then set level, plumb, and square; no shims-and-hope approach on a window this size. The perimeter seal is an AAMA 812 low-expansion foam, applied to seal the frame to the structure without bowing it. Fastening follows AAMA 2400/2410 installation practice.
Your Palm Beach project may require a permit, and the building department will ask for the NOA or Florida Product Approval submittal for every window in the scope. We provide those. After installation, we water-test the sill track and verify the operable panels run freely, then clean the job site and walk you through operation. Improper installation compromises the performance of the rated system and can void the approval your permit depends on. That’s the whole reason we do our own installs in Palm Beach and don’t subcontract them out.
Frequently Asked Questions - 3-Panel Sliding (3-Lite Roller) Windows
Design pressure on your specific units is matched to the wind zone of your Palm Beach address, up to +/-100 and never higher. We calculate the DP from the opening size, building height, and exposure category, then specify the configuration that meets code without over-engineering the job. Call (561) 782-7525 and we’ll verify the rating for your exact address on the quote.
Lead times run on a product line-by-line basis. Some of our 3-lite roller configurations ship in a few weeks, others in a few months depending on finish, glass package, and the manufacturer’s current backlog. We’ll confirm the lead time for your exact specification when we write the quote. Call (561) 782-7525 to start.
Yes. If you’re replacing windows in Palm Beach, the building department will ask for the NOA or Florida Product Approval number for every unit in your permit packet. We provide the correct submittal for the configurations you order. The approval exists per configuration, so the number on your quote is the one your permit needs.
Width, height, track configuration, glass package, and finish are selected per opening. The 3-lite configuration can be 2 fixed with 1 operable or 1 fixed with 2 operable, depending on how you want the room to ventilate. We’ll measure your existing openings in Palm Beach and spec the units around them. Call (561) 782-7525 for a free on-site measurement.
Wipe the frame and track with mild soap and water every few months, especially if you’re near the salt air in Palm Beach. Keep the bottom track clear of sand and debris so the rollers run clean. Check the weep holes at the sill to confirm they drain. The track doesn’t need lubrication; most modern roller carriages run dry. If a panel starts to drag, call us before forcing it; the issue is usually adjustability, not a part that needs replacing.
