Double Hung Windows in Delray Beach, FL | TruePane Windows & Doors
Double hung windows are the classic vertical-glide window, with two sashes that slide up and down independently. For Delray Beach homeowners, the impact-rated version of this familiar profile means you don’t have to give up traditional curb appeal to get true hurricane protection. Both sashes tilt inward for easy cleaning, and laminated impact glass stays in place under flying debris. TruePane Windows & Doors installs these windows across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, and we’ve been serving Delray Beach long enough to know exactly what HVHZ compliance means in this wind zone.

Product Overview - Double Hung Windows
Double hung windows are one of the most requested profiles we install in Delray Beach. The reason is simple: they look right on Florida coastal architecture, and the impact version performs dramatically better than standard builder-grade windows. The vertical-glide operation gives you ventilation from the top sash, the bottom sash, or both at once, a real advantage on winter days when Delray Beach temperatures finally dip and you want airflow without direct breeze. Both the upper and lower sashes tilt inward, so cleaning second-story windows from inside the house is straightforward.
What makes our impact double hungs suited to hurricane-prone construction starts with the glass package. Each sash uses laminated impact glass with a PVB interlayer that holds glass fragments in the frame under impact. The frame itself is available in aluminum or vinyl, both engineered for the coastal environment we work in. Aluminum gives you narrow sightlines and structural rigidity. Vinyl offers thermal resistance and a lower-maintenance finish. Both take the same quality of hardware, the same clean traditional profile, and the same HVHZ-conforming installation our crew is known for in Delray Beach.
Architecturally, double hungs fit Delray Beach homes that lean traditional, colonial, coastal cottage, or Mediterranean. They read as “classic Florida” while doing heavy lifting no traditional window was ever asked to do.

Hurricane & Compliance Performance
Six things matter when you’re buying impact double hung windows in Delray Beach. Here’s what each one does and why it matters for your house.
Laminated Impact Glass
Each sash carries laminated glass with a PVB interlayer. When a 2×4 or piece of flying debris hits, the glass may crack, but the interlayer holds the pane together in the frame. That keeps wind and rain outside where it belongs, and it keeps the pressure envelope on your house intact during the storm.
Miami-Dade NOA / Florida Product Approval
Every configuration of our impact double hungs carries a Miami-Dade NOA (Notice of Acceptance) or Florida Product Approval number. These numbers are configuration-specific, so the exact model and size you order determines which number applies. We’ll verify the specific approval on your written quote before you sign anything.
FBC / HVHZ Compliance
These windows are engineered to Florida Building Code High-Velocity Hurricane Zone requirements. That’s the more demanding standard that applies in Palm Beach County and other coastal wind zones. Not every window sold as “impact rated” is HVHZ compliant. Ours are built and installed to that standard in Delray Beach.
TAS 201 / TAS 202 / TAS 203 Testing Context
The TAS protocol family is how HVHZ-rated products are tested and validated. TAS 201 covers large-missile impact, TAS 202 covers cyclic wind-pressure loading, and TAS 203 covers forced-entry resistance. These are the tests behind the approval numbers, and they describe how the product behaves in real storm conditions, not just in a lab.
Design Pressure for Your Wind Zone
Design pressure is the structural wind rating, expressed as positive and negative pressure. Our double hungs are matched to your actual wind zone, up to +/-100, and never higher. Putting a higher-rated window in a lower-rated opening doesn’t improve performance, it just costs you money. We size the rating to the need.
Energy Performance Options
Low-E and insulated glass options are available on our impact double hungs, which gives you both hurricane protection and better heat management. In Delray Beach, the Low-E coating on the outer lite cuts solar heat gain while the impact lamination does the storm work. It’s not a compromise; it’s a layered package.
Color & Glass Options
The finish you choose changes the personality of the window. On Delray Beach Mediterranean homes, Bronze and Tan frames sit quietly against earth-toned exteriors. White is the default choice for coastal cottages and more traditional elevations, and it’s the most cost-efficient. Black frames have become popular on modern renovations where higher-contrast windows are part of the look. Almond splits the difference and works well on stucco or pastel exteriors without the sweetness of white.
Glass selection follows function first. Clear laminated impact glass prioritizes daylight and view. Tinted laminated glass reduces solar heat gain and glare, a real consideration for east- and west-facing walls in Delray Beach. Low-E insulated glass adds the strongest energy performance package, ideal if you’re replacing every window on the house and want to cut air-conditioning load. We’ll help you match the glass to the orientation of each wall during your consultation.
Screens come half or full. Half screens cover only the bottom sash opening. Full screens cover the entire window. If you run your windows open frequently in the cooler months, full screens make sense.
Installation by TruePane Windows & Doors in Delray Beach
An impact window is only as good as its installation. That’s not a line. The NOA and Florida Product Approval numbers apply to the product as installed, and a window that’s not set level, plumb, and square will not perform to its design pressure in a storm. We’ve replaced windows in Delray Beach that were expensive, rated, approved, and installed incorrectly enough to leak or fail. The product was fine. The labor wasn’t.
Every double hung install from TruePane Windows & Doors starts with a pre-install inspection of the rough opening. We check the framing, the existing water barrier, and any signs of prior leakage or rot. If the opening isn’t right, we fix it before the window goes in. We set the window level, plumb, and square, then seal the perimeter per AAMA 812 practice using low-expansion foam. That seal matters for both water intrusion and air leakage. It’s a small step that too many crews skip or rush in Delray Beach wind zones.
Our installation practice follows AAMA 2400/2410 standards, which cover installation methods for windows in exterior walls. We finish with a water test when conditions allow, then clean up the opening and the surrounding work area. For Delray Beach properties in HVHZ jurisdictions, we’re familiar with permit submittal for impact products, and we provide the NOA or Florida Product Approval documentation your permit application needs. Coastal exposure, wind zone, and the condition of your existing openings all influence how the job is scoped. We handle all of it.
Frequently Asked Questions - Double Hung Windows
Our impact double hung windows are rated for the specific wind zone of your Delray Beach property, with design pressures available up to +/-100. We never oversell a higher rating than the opening requires. We’ll verify the exact design pressure for your address and opening dimensions during your quote.
Lead time depends on the manufacturer line, frame material, glass package, and finish. Standard configurations usually run a shorter timeline. Custom sizes or specific finish combinations add time. We’ll give you a written lead-time estimate with your quote, and we won’t schedule installation until the windows have physically arrived at our shop. Call (561) 940-2917 for a current estimate.
Yes, in almost all HVHZ cases your permit review will require the NOA or Florida Product Approval documentation for the exact window configuration being installed. We provide the correct approval documentation with your permit package, matched to the product and size you actually order. No guesswork, no generic paperwork.
Yes. Impact double hungs are built to your opening dimensions, not sold only in off-the-shelf stock sizes. That’s standard for impact products. If you’re replacing an unusual window in an older Delray Beach home, we’ll field-measure and order to those dimensions. Configuration options include glass package, frame material, finish, and screen type.
Maintenance is modest. Vinyl frames need periodic cleaning with mild soap and water; avoid abrasive cleaners. Aluminum frames benefit from an annual rinse to prevent salt buildup near the beach in Delray Beach. The tilt-in sashes make glass cleaning simple from inside the house. Hardware and tracks should be kept free of sand and debris, which is common in coastal environments.
