3-Panel Sliding (3-Lite Roller) Windows in Fountainebleau, FL | Winslow Windows & Doors
If you’re widening a wall opening or replacing a dated picture window in Fountainebleau, a 3-panel sliding window gives you the glass area you want without sacrificing horizontal glide. These units pair one operable lite that rolls smoothly on a track with fixed panels that hold laminated impact glass, so the whole assembly stays code-compliant under Florida Building Code High-Velocity Hurricane Zone requirements. Winslow Windows & Doors supplies and installs this profile across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, and we’ve set them in homes throughout Fountainebleau where coastal wind exposure makes the glazing specification matter. Call (727) 620-6983 to talk through sizes and material choices.

Product Overview - 3-Panel Sliding (3-Lite Roller) Windows
A 3-panel sliding window, sometimes called a 3-lite roller, is built for wide openings that still need operable ventilation. Two of the three lites can be fixed while one slides, or you can specify two operable lites with a single fixed panel in the middle. Either way, you get horizontal sightlines with generous daylight, which suits Fountainebleau living rooms, master suites, and sunrooms where a double-hung would feel pinched at the width.
Every configuration we order for Fountainebleau homes carries laminated impact glass across all three lites. The PVB (polyvinyl butyral) interlayer is the layer that holds the glass together when something hits it, which is why this product family gets specified for hurricane-prone construction in South Florida. The frames come in aluminum or vinyl, both reinforced to carry the weight of three impact-rated sashes without sagging over decades of daily use. What separates a pleasant window from a problematic one is the installation around it. We set every unit level, plumb, and square, then seal the perimeter with AAMA 812 low-expansion foam as part of our AAMA 2400/2410 installation practice. A window can carry a perfect NOA and still leak if the rough opening is out of tolerance, so the install detail is non-negotiable for us.

Hurricane & Compliance Performance
Laminated Impact Glass
All three lites carry laminated glass with a PVB interlayer. Under impact, the interlayer holds the glass in the frame instead of letting shards enter the room. That’s the core protective mechanism in this product, and it’s tested rather than assumed for Fountainebleau installations.
Miami-Dade NOA / Florida Product Approval
Each configuration carries its own Notice of Acceptance and Florida Product Approval numbers. These are issued per configuration, not blanket documents. When we prepare your quote, we include the specific approval numbers that match your frame material, glass package, and size, so your permit submittal in Fountainebleau goes through without back-and-forth.
FBC / HVHZ Compliance
The product is engineered to Florida Building Code High-Velocity Hurricane Zone requirements. HVHZ is the stricter standard that governs Miami-Dade and Broward construction, and it’s the standard relevant to Fountainebleau. A window that passes HVHZ testing has already cleared the bar for most of the state.
TAS 201 / 202 / 203 Testing Context
HVHZ-rated products are tested under the TAS protocol family. TAS 201 covers large-missile impact, TAS 202 covers cyclic wind-pressure loading that simulates a hurricane’s pulsing gusts, and TAS 203 covers forced-entry resistance. These three tests are the reason an impact window carries the paperwork it does.
Design Pressure for Your Wind Zone
Design pressure is matched to your wind zone and never specified higher than +/-100. Over-specifying a DP rating adds cost without adding protection for the actual wind loads Fountainebleau sees. We size the rating to your specific opening location on the structure, so you’re not paying for a rating your home never needed.
Energy Performance Options
Low-E insulated glass is available as an upgrade on the operable lites, and it’s a worthwhile one for west-facing Fountainebleau rooms that take afternoon heat. Tinted glass is another option if glare is a bigger problem than heat gain. Both packages work with the impact laminate to balance protection with comfort.

Color & Glass Options
Fountainebleau homes run the full spectrum from mid-century block to newer Mediterranean-style builds, which is why we keep five frame finishes in regular rotation. White and black frames work on the contemporary side, black especially so when it matches millwork or lighting. Bronze and tan frames disappear into warmer palettes, and they’ve held up visually on stucco exteriors without fading to chalk. Almond splits the difference for homes that are neither fully modern nor fully traditional.
Glass choice comes down to three questions: where the window faces, what’s on the other side of it, and how much daylight you want. Clear laminated glass keeps the view unobstructed. Low-E insulated glass reduces heat transfer and is the pick for east and west elevations in Fountainebleau. Tinted glass handles hard glare and gives privacy during daytime hours without film. The operable lite can carry a different glass package than the fixed lites if you’re balancing cost against performance, and we’ll walk you through the trade-off on site.
Installation by Winslow Windows & Doors in Fountainebleau
We approach every Fountainebleau installation as a system install, not just a sash swap. The process starts with a pre-install inspection that checks the rough opening dimensions, existing framing, and any water intrusion history around the old window. In Fountainebleau we’re working with coastal wind exposure and salt air against aluminum frames, so we’re looking for existing sill rot, failed flashing, or caulk lines that suggest the old unit was leaking. If the rough opening is out of square, we correct it before the new unit goes in; the NOA rating means nothing if the frame is racked.
Setting is done level, plumb, and square to the fraction of an inch. Then comes the AAMA 812 low-expansion foam around the perimeter, which seals the gap between frame and rough opening without bowing the jamb. We follow AAMA 2400/2410 installation practice, which covers the flashing, shimming, and sealing details that keep South Florida water out during seasonal rains and wind-driven storms. After the unit is set and sealed, we run a water test, clean the tracks and glass, and walk you through operation and maintenance. Permitting for HVHZ jurisdictions is part of the process, and we make sure the NOA or Florida Product Approval docs land with your permit package in the right form. In Fountainebleau, that paperwork is what separates a window that passes inspection from one that stalls your project.
Frequently Asked Questions - 3-Panel Sliding (3-Lite Roller) Windows
What wind zone / design pressure is the 3-Panel Sliding (3-Lite Roller) Window rated for?
Design pressure is matched to the wind zone of the specific opening, up to a ceiling of +/-100. We never spec higher than the opening requires. Your quote will state the exact DP for your configuration, and it will correspond to the Fountainebleau wind-load requirements for your wall and roof condition. Call (727) 620-6983 for a site-specific rating.
What is the lead time for a 3-panel impact window?
Lead time depends on the frame material, glass package, and which manufacturer line we’re drawing from (PGT, CGI, CWS, ES Windows, ECO, or Mr-Glass), but you should plan for several weeks from signed approval to delivery in Fountainebleau. We’ll give you a firm window at the quote stage and confirm it before you sign.
Does it require a Miami-Dade NOA or Florida Product Approval submittal for my permit?
Yes. In Fountainebleau and surrounding HVHZ jurisdictions, the permit package needs the product approval number that matches your exact configuration: frame, glass, size, and DP. We pull the correct NOA or Florida Product Approval document for your specific unit and include it with the permit submittal, so you’re not chasing paperwork on your own.
Can I customize the size or configuration?
Yes, within the structural limits of the product. You can choose 2 fixed plus 1 operable or 1 fixed plus 2 operable, aluminum or vinyl frame, any of the five finish colors, and your glass package. Width and height are set to your rough opening rather than off-the-shelf increments. We’ll confirm what’s achievable at the free on-site measurement.
How do I maintain the frame and track?
Keep the bottom track clear of sand and debris, especially with Fountainebleau’s proximity to the coast. Rinse with water, wipe down with mild soap, and avoid petroleum-based cleaners on the rollers and weatherstripping. Annual lubrication of the rollers with a dry silicone product keeps the operable lite gliding easily. The fixed lites need nothing beyond normal glass cleaning.
