AfterDouble Hung Windows in Miami, FL | TruePane Windows & Doors
Double hung windows give you the classic vertical glide homeowners love, with both sashes moving independently for real ventilation control. In Miami, that traditional profile has to work a lot harder than it does up north. Our Double Hung Impact Series pairs that familiar look with laminated impact glass and an engineered frame that stands up to high-velocity hurricane zone demands. TruePane Windows & Doors installs these systems across Miami, FL, from Coral Gables to Pinecrest, with the same care we bring to every opening we seal. Call (561) 489-4036 to talk through your project and get a free estimate.
Product Overview - Double Hung Windows
The Double Hung is the window Miami homeowners ask for when they want impact protection without giving up the architectural character of their home. Both the top and bottom sashes slide vertically and tilt inward, which makes cleaning and ventilation easy even on a second story. It is the workhorse window for older Florida homes, Spanish-Mediterranean designs, and anywhere a casement or slider would look out of place.
What makes this product suited to hurricane-prone construction starts with the glass. We build every Double Hung Impact Series window with laminated impact glass, using a PVB interlayer that holds the pane in the frame even if impact shatters the outer surface. That matters in Miami, FL, where a broken window during a storm turns a house into a wind tunnel in seconds. The frame itself is available in aluminum or vinyl, both engineered to true fix in the opening and keep that laminated glass exactly where it belongs.
Mechanically, the vertical-glide design is straightforward and reliable. Balance systems carry the weight of each sash smoothly, and the tilt-in function is a practical convenience for maintenance. But the purchase decision here is about more than convenience. It is about a window that carries a Miami-Dade NOA and Florida Product Approval, because in South Florida a window is only as good as the paperwork behind it when the inspector shows up.
Technical Specifications
Here is what the Double Hung Impact Series is made of, in plain terms. Every configuration is quoted per opening, so you get exactly what your wind zone requires and nothing you do not need.
- Frame materials: Aluminum or vinyl. Aluminum suits modern and coastal-contemporary homes; vinyl insulates well and resists salt air without special coatings.
- Glass options: Laminated impact glass with PVB interlayer, Low-E insulated glass, tinted glass, and clear glass. You can layer Low-E or tint onto laminated glass for energy performance plus impact protection.
- Finish options: White, almond, bronze, black, and tan. All five hold up to South Florida sun exposure when specified correctly.
- Screen options: Half screen for lower-sash airflow, full screen for full-opening ventilation.
- Size range: Custom-fabricated per opening. No stock sizes forced into your rough opening.
- Design pressure: Matched to your wind zone, up to +/-100 PSF, never higher. We do not over-rate or under-rate an opening.
- Compliance documentation: Miami-Dade NOA and Florida Product Approval numbers issued per configuration, provided on your quote for permit submittal.
Hurricane & Compliance Performance
There is a lot of marketing noise around hurricane windows. Here is exactly what the Double Hung Impact Series delivers, feature by feature.
Laminated Impact Glass
Two panes of glass bonded with a PVB interlayer. Under impact, the glass may crack but the interlayer holds the fragments together and keeps the pane in the frame. That is the core of impact protection, and it is standard on every Double Hung Impact Series window TruePane installs in Miami.
Miami-Dade NOA / FL Product Approval
Each window configuration carries a Miami-Dade Notice of Acceptance and Florida Product Approval number. These are issued per configuration, not blanket ratings. We verify the exact approval for your specific size, glass package, and frame material on your written quote before you commit.
FBC / HVHZ Compliance
Engineered to Florida Building Code High-Velocity Hurricane Zone requirements. This is not an optional add-on. Miami-Dade and Broward permit reviews demand it, and your homeowner’s insurance documentation depends on it.
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, the repeated push-pull that weakens a weak assembly over hours of storm exposure. TAS 203 covers forced-entry resistance, which matters for security long after hurricane season ends.
Design Pressure for Your Wind Zone
Design pressure is matched to your wind zone, up to +/-100 PSF, never higher. If your home sits a mile inland in Kendall, you do not need the same rating as a condo line on Brickell. We calculate per opening, per elevation, per exposure, so your quote reflects what your specific structure requires.
Energy Performance
Low-E and insulated glass options are available on the Double Hung Impact Series. So your impact protection also cuts solar heat gain, which in Miami means a more comfortable room and less work for your air conditioner. All without diminishing the impact rating of the laminated glass package.
Color & Glass Options
The finish on a window does more than look good. It has to survive South Florida sunlight without fading, chalking, or warping. Our white and almond finishes are the go-to choices for the classic Miami look you will see all over Coral Gables and Shenandoah. Bronze and black finishes suit modern builds and sharp contrast trimming on lighter stucco. Tan works well on Mediterranean-style homes where pure white feels too harsh.
On the glass side, clear laminated impact glass preserves the truest light and view. Tinted laminated glass reduces glare and adds daytime privacy. Low-E insulated laminated glass is the full package: impact protection, thermal performance, and sound damping. In a city where the sun beats on east-facing windows every morning, Low-E on your morning-light rooms is a decision you will feel. We help you match glass and finish room by room, because a bedroom that faces the water has different needs than a shaded side yard.
Installation by TruePane Windows & Doors in Miami
A window with a perfect Miami-Dade NOA means nothing if the installation is sloppy. The NOA-rated system only performs as tested when it is set correctly in the opening. So our installation practice follows AAMA 2400 and 2410 standards, and we use AAMA 812 low-expansion foam perimeter sealant. That foam is not a cosmetic step. It is the air and water barrier that fills the gap between the window frame and the rough opening, and it has to be done right or water finds its way in during the first afternoon thunderstorm.
Every TruePane installation in Miami, FL starts with a pre-install inspection of the opening. We check the rough opening dimensions, look for rot or termite damage in existing wood framing, and confirm the wind zone and exposure match the window we are putting in. We set the frame level, plumb, and square before any fastener is driven. Then we seal the perimeter, install the sashes, and do a final water test before trim goes on.
Permitting in Miami matters. HVHZ jurisdictions want to see that NOA and Florida Product Approval before they will close out your permit. We know what the plans examiners are looking for, and we provide the documentation with your quote. Coastal exposure, wind zone maps, and product approval submittals are not things you want to navigate alone. When an inspector sees a TruePane installation, they see a clean opening, correct fastening, and paperwork that matches the window in the wall.
Frequently Asked Questions - Double Hung Windows
The Double Hung Impact Series is rated with design pressures matched to your wind zone, up to +/-100 PSF, never higher. We calculate the required rating per opening based on your location, exposure, and building height in Miami, FL, then specify the window to match. Call (561) 489-4036 and we will tell you exactly what your home needs after a quick site review of your elevation and exposure.
Lead time depends on your frame material, glass package, and finish. Stock-size aluminum units with clear laminated glass typically move faster than custom vinyl with Low-E insulated laminated glass. We give you a firm lead-time window on your quote, not a vague “weeks” answer. Call (561) 489-4036 to get a project-specific timeline.
Yes. Miami-Dade and most HVHZ jurisdictions require the NOA and Florida Product Approval for your specific configuration as part of the permit package. We provide those documents with your quote, and we stand behind them through inspection. Call (561) 489-4036 and we will walk you through what your municipality is going to ask for.
Yes. We fabricate per opening, not from stock bins. You pick the frame material, glass package, finish, and screen type. We build to fit your rough openings. If you are replacing old windows in a 1950s Coral Way home, we measure every opening individually, because “standard size” does not exist in older Miami housing stock. Call (561) 489-4036 to schedule a free on-site measurement.
The tilt-in sashes make cleaning both sides of the glass easy from inside your home. For the frame, clean the tracks a couple of times a year with a soft brush and mild soap, and keep the weep holes clear so water drains correctly. Aluminum frames in salt-air environments benefit from an annual rinse. Do not use abrasive cleaners on any finish. If a balance system ever needs attention, call us rather than forcing the sash, because a damaged balance will make the window hard to operate and can compromise the weather seal. Call (561) 489-4036 with any service concern.
