Double Hung Windows

Double Hung Windows in Miami Gardens, FL | TruePane Windows & Doors

Double hung windows are the classic vertical-glide window profile you see on traditional Florida homes: two sashes that slide up and down, and on our impact series, both the top and bottom sashes tilt inward for easy cleaning. Homeowners in Miami Gardens choose this style because it looks right on ranch houses, Mediterranean-inspired stucco homes, and everything in between, while still delivering the hurricane protection this region demands. TruePane Windows & Doors installs double hung impact windows across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, so you get the profile you want with the compliance documentation your permit office needs.

Product Overview - Double Hung Windows

Double hung windows carry a traditional look that fits Miami Gardens architecture better than almost any other operable window style. Both sashes move independently, which gives you ventilation control that casement or picture windows simply do not offer. On a hot afternoon when there’s no breeze at ground level, you can drop the top sash and let warm air escape while the bottom sash stays closed to keep kids and pets inside. That is a real, daily convenience in South Florida, not a brochure talking point.

The impact version of this window is a different animal from the double hung windows sold up north. Here, the glass is the structural event. Laminated impact glass with a PVB interlayer is bonded between two panes, and when debris hits it during a storm, the glass cracks but the interlayer holds the shattered pane in the frame. Debris stays out. Wind pressure stays outside. Your living room does not become a wind tunnel. That is the entire point of the Miami-Dade NOA system, and it’s why we will not sell you a non-impact double hung for an opening that is required by code to be protected.

The frames come in aluminum or vinyl. Aluminum gives you a thinner sightline and a more architectural look, which is why it is common on mid-century and custom homes across Miami Gardens. Vinyl is thermally efficient, easy to maintain, and a strong value on rental properties and single-family homes where budget matters. Both frame materials are engineered around the laminated glass package, not adapted to it after the fact.

The sashes on these units tilt inward. That is a feature worth highlighting because cleaning second-story windows from the outside is not something anyone in Miami Gardens should be doing in July. With the tilt-in mechanism, both sashes rotate into the room so you can clean the exterior glass from inside the house safely. It sounds small. After your first summer of owning them, you will disagree.

Technical Specifications

Every double hung impact window we install in Miami Gardens is ordered per opening, not pulled off a shelf in a generic size. Here is what we configure per project:

• Frame materials: Extruded aluminum or multi-chamber vinyl, specified by the architectural style and exposure of the home.
• Glass options: Laminated impact glass (PVB interlayer), Low-E insulated glass, tinted glass, and clear glass, available in combinations that make sense for the elevation and window orientation.
• Finish colors: White, almond, bronze, black, and tan. These are the colors we order most in Miami Gardens, where white and almond dominate rental and production housing and bronze and black are increasingly common on newer custom work.
• Screen options: Half screen or full screen, selected to match how the customer actually uses the window.
• Design pressure: Matched to your specific wind zone, up to +/-100. We do not oversell higher DP ratings than the opening requires, and we will explain why on your quote.
• Sill and track configuration: Selected per opening to drain properly under South Florida rain loads.

What this means in practice: you are not buying a “double hung window.” You are buying a specific double hung window, sized and assembled for the opening it will occupy, with a documented design pressure that satisfies the Florida Building Code for your address in Miami Gardens.

Hurricane & Compliance Performance

Laminated Impact Glass
The core of this product is laminated impact glass with a PVB interlayer. When a storm-driven object hits the pane, the glass fractures but the interlayer keeps the pieces bonded together and held in the frame. The window stays sealed against wind and rain even after the glass has been hit. That is the protection Miami Gardens homeowners are paying for, and it works.

Miami-Dade NOA / Florida Product Approval
Each configuration we quote carries its own Miami-Dade Notice of Acceptance or Florida Product Approval number. These numbers are issued per product configuration, meaning the exact size, frame, and glass combination in your quote has been approved. We provide the applicable approval documentation with your quote so your permit moves through the Miami Gardens building department without surprises.

FBC / HVHZ Compliance
These windows are engineered to the Florida Building Code High-Velocity Hurricane Zone requirements. HVHZ is the strictest wind-borne debris region code in the country, and Miami Gardens sits inside it. When we say a product is HVHZ-rated, we mean it has passed the testing and documentation standards for this specific zone, not a looser coastal standard from another state.

TAS 201 / 202 / 203 Testing Context
HVHZ-rated products are tested under a family of Florida-specific protocols. TAS 201 governs large-missile impact, meaning a length of lumber fired at the window to simulate storm debris. TAS 202 covers cyclic wind-pressure loading, which replicates the repeated pressure changes of a hurricane, not a single blast. TAS 203 tests forced-entry resistance. A double hung impact window that has passed this battery is a hardened building component, not a standard window with upgraded glass.

Design Pressure Matched to Your Wind Zone
Design pressure is the amount of wind pressure, positive and negative, that a window is rated to withstand. These units are configured to match the design pressure of your specific wind zone, up to +/-100. We do not sell you a higher DP than your opening requires, because every dollar of unnecessary engineering is a dollar you could spend somewhere else on the project.

Energy Performance Options
Low-E and insulated glass options improve the energy performance of the window while keeping the impact protection. On western-facing elevations in Miami Gardens, where afternoon sun is punishing, a Low-E insulated laminated unit makes a material difference in how the room feels. On north-facing openings, clear laminated impact glass is often the better value. We will show you both options and let you decide.

Color & Glass Options

Finish color does more for curb appeal than people expect. White and almond remain the two most common choices across Miami Gardens, and for good reason: they fit the stucco and tile aesthetic that dominates so many neighborhoods here. Tan reads warm and works well on earth-toned homes. Bronze and black are bolder choices that have become increasingly popular on modern builds and on homes where the owners want window frames to read as architectural lines rather than disappear into the wall.

On the glass side, your choice depends on where the window faces and how the room is used. Clear laminated impact glass gives you maximum visible light and the most natural view. Tinted laminated glass cuts glare and adds a degree of privacy, which matters on front elevations or any window facing a neighbor’s wall. Low-E insulated glass is the choice for rooms that get direct afternoon sun, because it reduces the heat that passes through the glass without making the room feel dark. We carry all of these options across the PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass product lines, and we will walk you through the trade-offs in plain language, not spec-sheet jargon, when we quote your Miami Gardens project.

Installation by TruePane Windows & Doors in Miami Gardens

An impact window is only as good as its installation. This is not a sales line; it is the physical reality of how these products work. A Miami-Dade NOA is issued for a window installed according to the approved installation method. When a crew skips steps, the opening no longer performs to the tested standard, and the documentation your permit is built on becomes fiction. That is why we are specific about how we install every double hung window that leaves our shop.

Our process starts with a pre-installation inspection of each opening. We are looking for water damage, rot, failed sealant, or framing that has moved, especially on older Miami Gardens homes where the rough opening was built before today’s code existed. We document what we find, and if there is a problem that affects the window’s long-term performance, we address it before the new window goes in. We do not hide problems behind trim.

Set out is done level, plumb, and square, with shims placed to hold the frame true while we fasten it to the rough opening. The perimeter is sealed with AAMA 812 low-expansion foam, which creates an air and water seal without bowing the frame the way standard expanding foam can. Interior and exterior joints are then sealed with compatible sealant that can handle Miami Gardens’ wet season expansion and contraction. Our installation practice follows AAMA 2400 and 2410 standards for window installation, which are the recognized protocols for proper flashing and weatherproofing.

Once the window is set, we conduct a water test before we finish the interior trim. That is your best defense against discovering a leak three months after the job is done. Cleanup is part of the scope, not an afterthought. And because Miami Gardens sits inside the HVHZ, we understand what the building department wants to see at inspection: the right NOA or Florida Product Approval number tied to each opening, installed to the documented method. Professional installation is not a premium add-on. It is what makes the whole system true to its rating.

Frequently Asked Questions - Double Hung Windows

What wind zone / design pressure is the Double Hung Windows rated for?
These double hung windows are configured to match the design pressure of your specific wind zone, up to +/-100. Design pressure is calculated per opening based on the Florida Building Code and your home’s location, exposure, and building height, and we match the window to that requirement rather than selling a one-size-fits-all rating. Call (386) 516-5343 and we will calculate the required DP for your address in Miami Gardens.

What is the lead time on double hung impact windows?
Lead time varies by manufacturer and configuration, and it moves seasonally. Custom sizes, certain glass packages, and some finish colors can extend the timeline. We give you a written delivery estimate on your quote and update you if anything shifts. The best way to get a current lead time for your specific openings is to call (386) 516-5343.

Does my permit require a Miami-Dade NOA or Florida Product Approval submittal?
Yes, in Miami Gardens your permit package will need the applicable NOA or Florida Product Approval documentation for the specific window configurations being installed. We provide that documentation with your quote, so your contractor or permit runner has exactly what the building department requires. Bring us your window schedule early and we will handle it.

Can I customize the size or configuration of these windows?
The double hung impact windows we install are ordered per opening, not selected from stock sizes. That means most openings can be matched to a custom or semi-custom size within manufacturers’ engineering limits. If the opening is very large, or if the architecture calls for mulled combinations or unusual proportions, we will tell you what is feasible and what the code implications are before you commit.

How do I maintain the frame after installation?
Both aluminum and vinyl frames need periodic cleaning with mild soap and water, especially after the dusty dry season or after any storm that leaves debris on the sills. Keep the sill tracks clear of leaves and grit so drainage does not clog, and lubricate the tilt-in hardware annually. Avoid pressure washing directly at the glass or sealant lines. These are low-maintenance windows, but the track is the one place where neglect shows up first.
