Product Overview - Double Hung Windows

The double hung is the most traditional operable window profile in American residential architecture, and Miami Shores, FL has plenty of homes that lean on that look. It is a vertical-glide design: two sashes in a single frame, each sliding up and down on its own track. The catch for Florida buyers has always been that a traditional double hung, with its moving upper sash and meeting rail in the middle, is harder to engineer for hurricane impact than a fixed or casement window. The impact-rated versions we install solve that with laminated glass in both sashes and reinforced interlocking at the meeting rail.

What makes this profile work in hurricane-prone Miami Shores construction is the combination of tilt-in convenience and structural seriousness. The sashes tilt inward on both top and bottom, so a homeowner can clean the exterior glass from inside the house, which matters on second-story openings over tile roofs or tight zero-lot-line setbacks where a ladder is a hassle. Under that everyday convenience sits the real engineering: laminated impact glass with a PVB interlayer, a reinforced frame, and hardware that keeps both sashes seated under positive and negative wind pressure.

Architecturally, double hungs fit the 1920s Mediterranean Revival, 1950s ranch, and mid-century modern homes that make up much of the Miami Shores housing stock. They preserve the vertical proportions those facades were drawn around. We have installed them in the historic districts off NE 2nd Avenue, in the waterfront lots along Biscayne Bay, and in the quieter blocks west of the train tracks, and the profile reads right in every one of those settings.

Technical Specifications

• Frame materials: Aluminum or vinyl, depending on the opening and your budget. Aluminum carries narrower sightlines for larger openings; vinyl is what we often recommend for smaller window replacements where thermal performance matters more.
• Glass options: Laminated impact glass with a PVB interlayer, Low-E insulated glass, tinted glass, or clear glass. Combinations like laminated outer pane plus Low-E insulated inner pane are available depending on the manufacturer.
• Finish options: White, almond, bronze, black, and tan. These are stocked standard colors, not custom paint.
• Screen options: Half screen or full screen, depending on how much of the opening you want ventilated.
• Operation: Vertical glide, both sashes operable, both sashes tilt inward for cleaning.
• Design pressure: Matched to your wind zone, up to +/-100, never higher. We do not oversell a DP rating your opening doesn’t need.

Hurricane & Compliance Performance

Laminated Impact Glass
The core of the hurricane rating is laminated glass with a PVB (polyvinyl butyral) interlayer. When debris strikes, the glass may crack but the interlayer holds the shards in the frame, keeping the building envelope sealed. That stops wind-driven rain and pressure spikes from entering the home during a storm.

Miami-Dade NOA / Florida Product Approval
Every double hung configuration we quote carries the approvals Florida permits require. Miami-Dade NOA (Notice of Acceptance) and Florida Product Approval numbers are issued per configuration, so the number depends on the exact size, frame, and glass combination. We verify the specific approval on your written quote, and you will have it for your permit package.

FBC / HVHZ Compliance
These double hungs are engineered to Florida Building Code (FBC) High-Velocity Hurricane Zone (HVHZ) requirements. That is the stricter code that applies in Miami-Dade and Broward, and Miami Shores sits squarely inside it. An HVHZ-rated product is not a marketing label; it is a structural requirement your building department will check.

TAS 201 / 202 / 203 Testing Context
HVHZ-rated windows are tested under the TAS protocol family: TAS 201 for large-missile impact, TAS 202 for cyclic wind-pressure loading, and TAS 203 for forced-entry resistance. The double hungs we install in Miami Shores are validated under that protocol, which is what gives the Miami-Dade NOA its teeth.

Design Pressure for Your Wind Zone
Design pressures are matched to your wind zone, up to +/-100, never higher. Putting a +/-100 DP window in a low-exposure interior bedroom is wasted money; putting a +/-40 DP window on a direct east-facing second-floor opening is unsafe. We calculate the required DP for each opening from the FBC wind-load maps and your exposure category.

Energy Performance
Low-E and insulated glass options are available for the double hung line. In Miami Shores, where sun exposure is relentless from April through October, a Low-E coating on the inner surface of the laminated glass cuts solar heat gain without changing the exterior look. Tinted glass is another option for openings that get harsh afternoon sun.

Color & Glass Options

The five finish options, white, almond, bronze, black, and tan, cover most of the homes we work on in Miami Shores, FL. White and almond read classic on the Mediterranean and Spanish Colonial facades. Bronze and black give a sharper, more contemporary line on mid-century and newer construction, and they hold up visually against the salt air better than lighter finishes show their age. Tan is a quieter neutral that works well on stucco homes where you want the window to recede.

Glass choice follows the opening. Clear laminated impact glass is the most economical hurricane option and preserves the truest exterior view, which matters on bay-facing elevations. Tinted glass cuts glare in east- and west-facing rooms. Low-E insulated glass is the pick for bedrooms and living areas where the AC runs hard from June to September. We walk through each opening with you during the site measurement and specify glass per opening, not per house, because an east-facing kitchen in Miami Shores does not need the same glass as a north-facing bedroom.

Installation by Winslow Windows & Doors in Miami Shores

An impact window is only as good as the opening it is set into. A Miami-Dade NOA rating assumes the window is fastened and sealed the way the approval documents specify. We install every double hung in Miami Shores, FL to AAMA 2400/2410 practice: that means the rough opening is inspected and prepped before the frame goes in, fasteners are placed per the manufacturer’s approved schedule, and the perimeter is sealed with AAMA 812 low-expansion foam plus a compatible sealant at the exterior.

Our process on double hung replacements and new construction runs the same way. We measure every opening on site, verify the existing framing and sheathing condition before quoting, and flag rot or termite damage before it becomes a change order. At install, each window is set level, plumb, and square, then checked for squareness after fastening because a cocked frame ruins the interlock at the meeting rail and defeats the impact rating. The sashes are installed, cycled, and adjusted for a clean glide. We finish with a water test on the first window of a run to confirm the perimeter seal is doing its job, then clean the glass and haul off the old frames and debris.

Miami Shores has its own permitting and inspection rhythm, and HVHZ jurisdictions are strict about product approvals being attached to the permit submittal. We pull permits, submit the Miami-Dade NOA or Florida Product Approval for the exact configuration being installed, and deal with the inspection. If the inspector wants to see the DP rating on the east elevation, we have it in the packet. That is part of the install, not an upsell.

Frequently Asked Questions - Double Hung Windows

What wind zone and design pressure is the double hung rated for?
Design pressures are matched to your specific wind zone and exposure category up to +/-100, never higher. The required DP for any opening in Miami Shores, FL depends on the building’s location, height, and surrounding exposure, and we calculate that per opening before we quote.

What is the lead time on double hung windows in Miami Shores?
Lead times run anywhere from 8 to 14 weeks depending on the manufacturer, frame material, glass package, and finish. Custom sizes and color-matched finishes tend toward the longer end. We confirm the current lead time on your written quote and schedule the install around it so there’s no gap between tear-out and setting.

Does my permit require a Miami-Dade NOA or Florida Product Approval submittal?
Yes. Miami Shores building permits for replacement windows in an HVHZ jurisdiction require the product approval documents for the exact configuration being installed. We pull the approval packet, match it to the sizes on your plan, and submit it with your permit application. Approvals are issued per configuration, so the number on a 36 x 60 double hung may differ from a 48 x 72. Call (727) 483-7883 and we will confirm the approvals before you get to the permit counter.

Can I customize the size or configuration of the double hung?
Sizes are built to the opening, up to the limits of each manufacturer’s approved size matrix. That includes custom widths and heights within the tested range, plus mulled combinations if you are replacing a wide opening with two or three units. Configuration options include different glass packages per opening, finish selection, and screen style. The one thing you cannot customize is the engineering: whatever size and glass you pick has to land inside the approved, tested range for that configuration.

How do I maintain the double hung frame and sashes?
Tilt both sashes inward and clean the glass with a soft cloth and mild soap; avoid abrasive cleaners on the vinyl and on the laminate. The tracks benefit from a quick vacuum twice a year to keep the glide smooth. The PVB interlayer is sealed inside the glass, so it needs no maintenance beyond keeping the exterior weep holes clear. In a coastal environment like Miami Shores, an annual rinse of the exterior frame keeps salt deposits from building up on the finish.
