Double Hung Windows

Double Hung Windows in Tampa, FL | Winslow Windows & Doors

Double hung windows are the classic American window profile: two sashes that slide vertically, tilting inward for easy cleaning. Here in Tampa, where summer humidity and hurricane season shape every building decision, the version we install carries laminated impact glass and heavy-duty engineering that turns a traditional look into a storm-rated system. Winslow Windows & Doors has installed impact-rated double hungs across Tampa neighborhoods from Hyde Park to Carrollwood, and we know what it takes to get them right: proper flashing, precise leveling, and sealant work that stands up to Florida rain.

Product Overview - Double Hung Windows

Double hung windows are one of the most versatile profiles you can put in a Florida home. Both the top and bottom sashes move, which means you get ventilation from either direction, and since both sashes tilt inward, you can clean every glass surface from inside the house. For two-story Tampa homes, that alone is a reason homeowners choose this style over fixed or casement windows.

What makes this version different from a builder-grade double hung is what is inside the glass and how the frame is tested. The impact series we install uses laminated glass with a PVB interlayer. When a windborne object hits the glass, the pane may crack, but the interlayer holds the broken pieces in place. That is not a convenience feature. In a hurricane, it is what keeps the wind envelope of your home intact and prevents sudden pressurization that can lift a roof.

Architecturally, double hungs fit nearly every home style you see in Tampa. They look right on bungalows in Seminole Heights, on Mediterranean revival homes in Davis Islands, and on newer coastal-modern builds in Westchase. The vertical proportions and clean meeting rail keep the traditional profile homeowners expect, while the laminated glass and Miami-Dade rated construction provide the protection Florida building departments require. Winslow Windows & Doors has installed this product across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, so we can match the right frame and glass package to your specific wind zone and architectural style.

Technical Specifications

Here are the material, glass, and finish options available on the double hung impact windows we install in Tampa. Every configuration is quoted specific to your home and wind zone.

• Frame materials: Aluminum or vinyl. Both are suited to the Tampa climate; aluminum offers the slimmest sightlines, while vinyl provides high thermal performance at a mid-range price point.
• Glass options: Laminated impact glass with PVB interlayer, Low-E insulated glass, tinted glass, and clear glass. Laminated is the impact-rated base; Low-E and tinted layers stack for energy performance and glare control.
• Finish options: White, almond, bronze, black, and tan. These five finishes cover most Tampa exterior palettes, from white coastal cottages to darker contemporary facades.
• Screen options: Half screen or full screen. A half screen covers the lower sash opening; a full screen lets you open the top sash for ventilation without inviting bugs.
• Design pressure: Matched to your wind zone, up to +/-100 pounds per square foot, never higher. We do not overspec design pressure because that does nothing but raise cost; the right rating is the one your building department requires.

Hurricane & Compliance Performance

Laminated Impact Glass
Each impact double hung carries laminated glass with a PVB (polyvinyl butyral) interlayer. Under impact, the glass may crack but stays held in the frame. That prevents wind and rain from entering the home after impact, which is what causes catastrophic structural failure in storms.

Miami-Dade NOA / Florida Product Approval
Miami-Dade NOA (Notice of Acceptance) and Florida Product Approval numbers are issued per configuration and verified on your specific quote. These are the documents your building department asks for when you pull a permit in an HVHZ jurisdiction.

FBC/HVHZ Compliance
The product is engineered to Florida Building Code (FBC) High-Velocity Hurricane Zone (HVHZ) requirements. That is the stricter standard applied in Miami-Dade and Broward, and it is accepted throughout Hillsborough County and the Tampa Bay region.

TAS 201/202/203 Testing Context
HVHZ-rated products like this one are tested under a protocol family that includes TAS 201 for large-missile impact, TAS 202 for cyclic wind-pressure loading, and TAS 203 for forced-entry resistance. These standards exist to simulate real storm and post-storm conditions, not marketing claims.

Design Pressure for Your Wind Zone
Design pressures are matched to your wind zone, up to +/-100 pounds per square foot, never higher. A home near Tampa’s waterfront requires a different rating than a home inland near New Tampa, and we specify accordingly.

Energy Performance
Low-E insulated glass options are available for energy performance. Low-E coatings reflect heat while letting light pass, which matters in Tampa where cooling loads dominate year-round. Tinted glass adds glare control for east- and west-facing rooms.

Color & Glass Options

The five finish options we offer are white, almond, bronze, black, and tan. White and almond are the most common on Tampa’s older bungalows and ranch homes, where they match existing trim and keep the window from visually overpowering the facade. Bronze and black work well on contemporary homes in channelside and South Tampa, where darker frames read as a design choice rather than a default. Tan bridges the gap, suiting Spanish and Mediterranean styles that are common in Bayshore and Palma Ceia.

Glass choice is driven by two things: impact requirement and comfort. Laminated impact glass is the structural base and is required for any opening that needs hurricane protection. Low-E insulated glass adds a coating and an insulating air space that cuts heat gain, which can matter a lot on a second-floor Tampa bedroom that gets afternoon sun. Tinted glass is a good fit for large west-facing exposures where glare is the primary complaint, and clear laminated is the budget-conscious option for shaded or north-facing elevations. We can mix glass packages across different elevations of the same house, which keeps cost down on sides that do not get direct sun.

Installation by Winslow Windows & Doors in Tampa

An impact window is only as good as the installation behind it. The NOA on the product means the window itself passed testing in a laboratory setting. The seal between that window and your home’s rough opening is built on site, by the installer. That is where most windows fail, and that is why we are specific about how our crew works.

Every double hung installation in Tampa starts with a pre-install inspection of the rough opening. We check for wood rot, water damage, and out-of-square framing before a single fastener goes in. If we find rot in the sill or jambs, we address it before the window is set. We set every unit level, plumb, and square, shimmed so the sash operates smoothly and the weatherstripping seals evenly all the way around. The perimeter is sealed with AAMA 812 low-expansion foam, then flashed and caulked to shed water the way the opening was designed to. Our practice follows AAMA 2400/2410, which covers the full scope of installation work from anchoring to flashing to finish.

After the window is installed, we run a final water test on the opening and walk the interior with the homeowner. In Tampa, where afternoon thunderstorms are part of daily life half the year, water intrusion is the most common call we get about failed installs from other contractors. We would rather catch it before we leave. Finally, we are familiar with the permitting process in HVHZ jurisdictions including Hillsborough County and the City of Tampa. We can provide the NOA and Florida Product Approval documentation your permit reviewer will ask for, and we coordinate inspections when required.

Improper installation compromises the entire NOA-rated system. A window that passes TAS 201 in a lab can fail in a real storm because the perimeter seal was done wrong. That is why we do not sell this product to homeowners who want to hand it to a handyman. The installation is the system.

Frequently Asked Questions - Double Hung Windows

What wind zone or design pressure is this double hung rated for?
Design pressures are matched to your specific wind zone, up to +/-100 pounds per square foot, never higher. The exact rating for your home depends on its location, height, and exposure; we determine that during the quote process and list it on your permit documents. Call (386) 559-6999 and we can verify the rating your project needs.

What is the lead time on double hung impact windows?
Lead times vary by manufacturer and configuration. The lines we install, PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass, each have their own production schedules, and custom colors or glass packages can add time. When we quote your project, we provide a current lead time estimate so you can plan around it. Call (386) 559-6999 for current production timelines.

Does my permit require a Miami-Dade NOA or Florida Product Approval submittal?
In most Tampa and Hillsborough County HVHZ jurisdictions, yes. The building department will ask for documentation proving the window meets Florida Building Code impact requirements. We provide the NOA or Florida Product Approval number for your exact configuration with your quote and permit package. Call (386) 559-6999 and we can walk you through what your specific jurisdiction requires.

Can I customize the size or configuration?
Yes. Double hungs are available in a wide range of widths and heights, and we can specify frame material, finish, glass package, and screen type independently. What a building department will accept depends on the tested size range for each NOA listing, so we will verify your custom dimensions against the approved configurations before finalizing the order. Call (386) 559-6999 to discuss your sizes.

How do I maintain an aluminum or vinyl double hung frame?
Wash the frames with mild soap and water a few times a year, and keep the sill track clear of debris so the sashes slide freely and water drains properly. The tilt-in sashes make glass cleaning simple from inside the home. Check the weatherstripping at the meeting rail annually, especially on Tampa homes near salt air, which can wear soft seals faster. Call (386) 559-6999 if you notice a sash binding or a seal that looks worn; small issues caught early are cheaper to fix.
