Double Hung Windows in Fountainebleau, FL | Winslow Windows & Doors
Double hung windows give you the classic vertical-glide profile Florida homeowners have trusted for generations, but ours are built for hurricanes. Both sashes move up and down, and both tilt inward for easy cleaning. That’s the part everyone knows. What matters more in Fountainebleau is what’s inside the frame: laminated impact glass that holds together when debris hits it at storm speed. Winslow Windows & Doors installs these across PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, and we’ve been doing it long enough to know that installation is half the product.

Product Overview - Double Hung Windows
A double hung window has two operable sashes stacked vertically. Both the top and bottom panels slide up and down, and on our impact series both tilt inward so you can clean the exterior glass from inside your home. That tilt-in feature matters more than most people expect in Fountainebleau, where salt air, rain, and pollen coat glass quickly. You don’t need a ladder, and you don’t need to lean out a second-story opening.
Architecturally, double hungs fit nearly every Florida home style. Mediterranean and Spanish Revival homes in Fountainebleau, with their symmetrical facades and stucco exteriors, look natural with vertical-glide windows. Mid-century and ranch homes do too. The traditional sightlines don’t fight the architecture. What separates an impact-rated double hung from a standard window is what you can’t see: laminated glass with a PVB interlayer, reinforced sashes, and interlocking frame components that resist both positive and negative wind pressure. When a window fails in a hurricane, it’s rarely the glass alone. It’s the glass plus the frame flexing plus the fastener pull-out. We address all three.
We offer the frame in aluminum or vinyl. Aluminum gives you the thin sightline profile that looks sharp on contemporary homes, and our finished aluminum holds up well in coastal exposure zones. Vinyl delivers thermal performance and a lower maintenance profile, which we recommend for homeowners who want a set-and-forget window. Both materials, when married to laminated impact glass and a properly engineered frame, meet the Florida Building Code’s High-Velocity Hurricane Zone requirements.
Technical Specifications
- Frame materials: Aluminum or vinyl, both engineered for HVHZ wind loads
- Glass options: Laminated impact glass with PVB interlayer, Low-E insulated glass, tinted glass, clear glass. Laminated impact glass is the hurricane-rated core; Low-E and tinted options stack energy performance on top of it
- Finish options: White, Almond, Bronze, Black, Tan. Finishes are factory-applied for durability and color consistency across the sash, frame, and mulls
- Screen options: Half screen for the bottom sash, or full screen for the entire opening. Screens are removable from inside for cleaning and replacement
- Operation: Dual sashes, vertical glide, tilt-in on both top and bottom. Sash locks and integrated interlocking meeting rail for weather resistance
- Design pressure: Matched to your wind zone, up to +/-100. We never over-spec beyond what the zone calls for because over-engineering adds cost without adding protection
Hurricane & Compliance Performance
Laminated Impact Glass
Two panes of glass bonded with a PVB (polyvinyl butyral) interlayer. When impact occurs, the glass may crack but it stays in the frame as a single sheet. That’s what keeps wind-driven rain and pressure surges outside your home, not inside widening a small fracture into a blowout.
Miami-Dade NOA / Florida Product Approval
Our configured double hung units carry Miami-Dade Notice of Acceptance and Florida Product Approval numbers. These are issued per configuration, so the exact approval on your quote depends on frame material, glass, size, and wind zone. We never claim a blanket approval covers every build. Match the configuration, match the number.
FBC / HVHZ Compliance
Every double hung we install in Fountainebleau is engineered to Florida Building Code High-Velocity Hurricane Zone requirements. HVHZ is the strictest wind standard in the country, and Fountainebleau sits inside it. There is no code path that lets you install a non-HVHZ window here and pass inspection.
TAS 201 / 202 / 203 Testing Context
HVHZ-rated products are tested under a specific protocol family: TAS 201 for large-missile impact, TAS 202 for cyclic wind-pressure loading, and TAS 203 for forced-entry resistance. These tests simulate the repeated pressure cycling of a hurricane, not just a single hit. Products that pass all three earn their NOA.
Design Pressure for Your Wind Zone
We match design pressure to the specific wind zone of your Fountainebleau property, up to +/-100. That rating means the window is tested and approved to resist that pressure cycling without structural failure. Higher numbers are not better. The right number for your zone is what code requires, and that’s what we specify.
Energy Performance
Low-E and insulated glass options are available on our double hung impact windows. Low-E coatings reduce solar heat gain through the glass, which matters in Fountainebleau where afternoon sun loads are intense. Insulated units with argon fill improve thermal comfort year-round. The laminated impact layer stays in place under all of it.

Color & Glass Options
Finish choices run five directions: White, Almond, Bronze, Black, and Tan. In Fountainebleau, where Mediterranean and coastal styling dominates, Almond and Tan blend naturally with stucco and warm exterior palettes. Bronze and Black create crisp contrast on white or light-gray homes, and black frames are a current favorite for modern builds and renovations. White remains the default for interior trim continuity, and it never looks wrong in a traditional Florida home.
On glass, your base decision is clear versus tinted versus Low-E. Clear laminated impact glass gives maximum visible light, and it’s the most economical choice. Tinted glass cuts glare and heat gain, and on west-facing windows in Fountainebleau it makes a measurable comfort difference. Low-E insulated glass is the upgrade for energy performance, reflecting radiant heat before it gets through the pane. We typically recommend Low-E on the west and south exposures, and clear or tinted elsewhere to balance cost. Every glass option carries the laminated PVB impact layer as the base.
Installation by Winslow Windows & Doors in Fountainebleau
An impact window is only as good as its installation. The NOA and Florida Product Approval numbers apply to the window as tested and installed, which is why improper fastening, poor sealing, or an out-of-square frame opening voids the performance the manufacturer engineered. That’s the part nobody talks about in the showroom, and it’s the part we obsess over.
Our process starts with a pre-install inspection of the opening. We check the rough framing, the existing waterproofing condition, and the fastening substrate. In older Fountainebleau homes we frequently find rotted sills or undersized headers, and those get corrected before the window goes in. Then we set the unit level, plumb, and square. We set it wrong and the sashes bind, the locks misalign, and the weatherstripping gaps. There’s no cosmetic fix for a racked frame.
Perimeter sealing uses AAMA 812 low-expansion foam sealant, which gives you air and water control without bowing the frame. We install per AAMA 2400 and 2410 standards, which cover the installation methods for windows and doors in residential construction. After set and seal, we run a water test on the perimeter and inspect the interior for any moisture entry before we call it done. Cleanup includes removal of the old units, packaging, and fasteners. Fountainebleau sits in a HVHZ jurisdiction, so permits and inspections are part of the job. We know what inspectors in this area look for, and we build the submittal package so the process moves without surprises.
Frequently Asked Questions - Double Hung Windows
What wind zone / design pressure is the Double Hung rated for?
We match the design pressure to your specific wind zone in Fountainebleau, up to +/-100. The exact rating on your quote depends on size, glass, and frame configuration. Call (727) 620-6983 with your address and we’ll confirm the wind zone requirements for your street.
What is the lead time on Double Hung Windows?
Lead times run about 6 to 10 weeks depending on the manufacturer and configuration. PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass each have their own production schedules, and custom sizes or finish combinations can extend that. We give you a firm timeline at quote so you can plan around it.
Does it require a Miami-Dade NOA or Florida Product Approval submittal for my permit?
Yes. Fountainebleau is in a HVHZ jurisdiction, and your permit package needs the NOA or Florida Product Approval number that matches your exact configuration. We prepare the submittal package as part of the project, and we don’t start installation until the permit is issued.
Can I customize the size or configuration?
Yes. Double hung units are available in standard and custom sizes within the manufacturer’s approved pressure range. That’s what “per configuration” means on the NOA: once you change dimensions or glass, we re-verify the approval. We’ll walk you through what’s feasible before you commit to anything.
How do I maintain the frame and sashes?
Wash the glass with mild soap and water, and keep the tracks clear of debris. The tilt-in sashes let you access both faces from inside. Lubricate the balance and track hardware once a year with a silicone-based lubricant, and check the weatherstripping every spring before hurricane season. If anything sticks, binds, or lets water in, call (727) 620-6983 and we’ll send someone out.
