Product Overview - Double Hung Windows

The double hung window is one of the most requested profiles we install in Doral, and for good reason. Both the top and bottom sashes operate, so you get airflow flexibility that a single hung just doesn’t offer. On a typical South Florida afternoon, you can drop the top sash to release warm air while keeping the bottom closed for privacy or child safety. The tilt-in feature on both sashes makes cleaning straightforward from inside the home, which matters a lot on second-story Doral bedrooms where climbing a ladder to clean exterior glass is not something anyone wants to do in July.

For hurricane-prone construction, the double hung profile has some real engineering advantages. The vertical slide tracks keep the sashes engaged along the full height of the frame, which distributes impact energy efficiently. When we build these with laminated impact glass, the PVB interlayer holds the glass in the frame even under direct impact, keeping wind and debris outside where they belong. You get a traditional profile with modern impact protection, and that combination is exactly what many Doral homeowners and condo associations are looking for.

The frame options are aluminum or vinyl. Aluminum gives you a slimmer sightline, which preserves more glass area and works well on contemporary and Miami-modern homes throughout Doral. Vinyl offers excellent thermal performance and requires minimal upkeep, which appeals to owners who want a low-maintenance product. Both frame materials are available in impact-rated configurations, so your choice comes down to architecture, budget, and personal preference, not compliance.

Hurricane & Compliance Performance

Laminated Impact Glass
The glass assembly uses a PVB (polyvinyl butyral) interlayer sandwiched between glass panes. Under impact, the glass may crack but the interlayer holds the fragments in the frame. That prevents flying debris from becoming an opening in your building envelope during a storm. This is the core protection mechanism in Florida impact-rated windows.

Miami-Dade NOA / FL Product Approval
Every impact-rated configuration we supply carries Miami-Dade NOA (Notice of Acceptance) and Florida Product Approval numbers. These are issued per configuration, not as a blanket product line approval. We verify the specific numbers on your written quote so your permit package is accurate before you submit anything to the building department.

FBC / HVHZ Compliance
The products we install are engineered to Florida Building Code (FBC) High-Velocity Hurricane Zone (HVHZ) requirements. Doral falls under HVHZ jurisdiction, which carries stricter standards than the rest of the state. This is not an optional upgrade here; it’s the baseline for code-compliant new construction and window replacement.

TAS 201 / 202 / 203 Testing Context
HVHZ-rated products 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. When you see these test references on a product approval document, you’re looking at proof the system was pushed hard in a controlled lab before it ever reached a Doral jobsite.

Design Pressure for Your Wind Zone
We match design pressure to your specific wind zone, up to +/-100, and never higher. That upper bound is not a limitation; it’s the honest ceiling of this product line. We’ll identify your exact exposure category and required DP rating during the measurement visit, so you don’t pay for a rating you don’t need.

Energy Performance
Low-E and insulated glass options are available on these double hung units. Low-E coatings reduce solar heat gain, which matters in Doral where the sun works against your air conditioner most of the year. Insulated glass improves thermal performance and can help with condensation control in air-conditioned spaces.

Color & Glass Options

The finish palette includes White, Almond, Bronze, Black, and Tan. In Doral, we see White and Almond most often on Mediterranean and Spanish-inspired homes, where warm neutrals keep the exterior palette cohesive. Bronze and Black are increasingly popular on modern builds and renovations that lean toward clean lines and darker trim accents. Tan splits the difference and works well on homes with natural stone or stucco in earth tones.

Glass selection depends on what you’re optimizing for. Laminated impact glass is the base requirement for hurricane protection. Low-E insulated glass builds on that with solar control and thermal insulation, which helps on west-facing elevations in Doral that catch the afternoon heat. Tinted glass reduces glare without changing the frame color. Clear glass is the most transparent option and works well when maximum visible light matters, such as on a shaded patio-facing window. We’ll walk you through the tradeoffs during your estimate.

Installation by TruePane Windows & Doors in Doral

Impact window performance lives or dies at the installation joint. A window can carry every Miami-Dade approval in the book, and still fail in a storm if it’s set out of square, under-shimmed, or sealed with the wrong materials. That’s why TruePane Windows & Doors treats installation as part of the product, not an afterthought.

Our process starts with a pre-install inspection of the rough opening. We check the existing framing, the condition of the buck if there is one, and any signs of water intrusion around the old window. Then we set the new window level, plumb, and square, shimming precisely so the operable sashes glide smoothly and the frame carries load evenly. We follow AAMA 2400/2410 practice for installation and use AAMA 812 low-expansion foam for the perimeter seal, which helps with air infiltration and water management without bowing the frame.

After the window is anchored, we run a water test on the perimeter and inspect the interior for any sign of leaks before we call the job done. Where permits are required, we understand the HVHZ submittal process in Doral and will make sure the product approval numbers on your window match what’s listed on your permit application. That detail trips up a lot of projects, and we’d rather handle it right the first time.

Our installers work throughout Doral, from the residential streets west of the Turnpike to the newer subdivisions near Downtown Doral. We know the local permitting rhythm and the typical exposure conditions here. Coastal exposure, even for inland Doral homes, affects design pressure requirements due to the flat terrain and lack of natural wind breaks, and we factor that into every quote.

Frequently Asked Questions - Double Hung Windows

What wind zone / design pressure is the Double Hung Windows rated for?
The double hung impact units we supply are engineered to Miami-Dade HVHZ requirements, with design pressures matched to your specific wind zone up to +/-100, never higher. Your exact required DP depends on window size, building height, and exposure category. Call (386) 854-7948 and we’ll calculate the precise rating for your openings.

What is the lead time?
Lead times vary by manufacturer and configuration. The lines we carry (PGT, CGI, CWS, ES Windows, ECO, Mr-Glass) each have their own production schedules, and custom sizes or specific finish colors can add time. We’ll give you a realistic window at quote, not an optimistic one that slides later.

Does it require a Miami-Dade NOA or Florida Product Approval submittal for my permit?
Yes. Doral building permits for replacement windows require product approval documentation, and the NOA or FL Product Approval number must match the exact configuration you’re installing. We provide the correct documentation with your order so your permit package is complete before your first inspection.

Can I customize the size or configuration?
Yes, within the engineering limits of each product line. Double hung windows are available in a range of standard and custom sizes, with either half or full screens, and with your choice of frame material, finish, and glass package. Some combinations may require a custom product approval evaluation, which we’ll identify early in the process.

How do I maintain the frame?
Vinyl frames clean with mild soap and water, nothing abrasive. Aluminum frames with a factory finish need the same light touch. The tilt-in sashes make glass cleaning easy from inside the home. For coastal-influenced areas of Doral, an occasional rinse of the track and weep holes keeps drainage working properly. We’ll review maintenance with you at install.
