Double Hung Windows

Double Hung Windows in Palm Beach Gardens, FL | TruePane Windows & Doors

Double hung windows are the classic vertical-glide design: two sashes that slide up and down independently, both of which tilt inward for easy cleaning. In Florida, the version that makes sense is the impact series, built with laminated glass that holds together under flying debris. TruePane Windows & Doors supplies and installs these across Palm Beach Gardens, Jupiter, North Palm Beach, and the surrounding coastal corridor. We work with the PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, so we can match the right frame, finish, and glass package to your home. Call us at (772) 794-8169 to talk through your options.

Product Overview - Double Hung Windows

Double hung windows have a traditional profile that suits nearly every architectural style we see in Palm Beach Gardens, from 1980s ranch homes in Eastpointe to newer Mediterranean builds in Mirasol and Alton. The appeal is practical: both the top and bottom sashes move, which gives you more control over airflow than a single hung, and both sashes tilt into the room so you can clean the exterior glass from inside. That matters when you’re on a second floor or your windows face a busy street or a screened pool deck you don’t want to drag a ladder across.

What makes these different from a standard double hung is the impact glass package. The laminated glass carries a PVB (polyvinyl butyral) interlayer between two panes. When something strikes the window, the glass may crack, but the interlayer holds the broken pieces in place and keeps the window sealed in the frame. That’s the same principle used in automotive windshields. It means the window keeps doing its job after impact, protecting the interior from wind, rain, and pressure buildup. Frame materials are aluminum or vinyl, depending on the line and your elevation, and the design pressure is matched to your specific wind zone rather than a one-size-fits-all number.

For homes in Palm Beach Gardens, this product fits where you want an operable window with a traditional look but you’re not willing to compromise on storm protection. It’s a strong choice for bedrooms, living rooms, kitchens, and anywhere you’d otherwise be reaching for a single hung. TruePane Windows & Doors installs these systems consistently across the HVHZ jurisdictions in southern Florida, and we make sure the final product looks as clean as it performs.

Hurricane & Compliance Performance

Laminated Impact Glass - The PVB interlayer is what separates an impact window from a standard window. Under impact, the glass may fracture, but the interlayer keeps the pane bonded and in the frame. In Palm Beach Gardens, where storms can throw everything from roof tiles to landscaping debris, that’s non-negotiable protection. It also means no plywood, no panels, and no pre-storm scramble.

Miami-Dade NOA / Florida Product Approval - Each configuration carries a Miami-Dade Notice of Acceptance or Florida Product Approval number. These are issued per configuration, not per product family, so the exact number depends on your size, frame, and glass combination. We confirm the correct approval on your written quote so your permit package is accurate before you pull it.

FBC / HVHZ Compliance - These windows are engineered to Florida Building Code High-Velocity Hurricane Zone requirements. Palm Beach Gardens sits within the HVHZ wind-borne debris region, which means the building department will ask for product approvals on the permit. We’re familiar with what Palm Beach Gardens and Palm Beach County reviewers expect to see.

TAS 201 / 202 / 203 Testing Context - HVHZ-rated products are tested under the TAS protocol family. TAS 201 covers large-missile impact, meaning a length of lumber fired at the glass. TAS 202 covers cyclic wind-pressure loading, which simulates the push-pull of sustained hurricane winds. TAS 203 covers forced-entry resistance. A product that carries these approvals has proven itself in a lab, not just on a spec sheet.

Design Pressure for Your Wind Zone - We match design pressure to your actual wind zone, up to +/-100, and never higher than what the structure requires. That’s important: over-engineering creates a window that’s unnecessarily heavy and hard to operate. Under-engineering is a code failure. Matching the number to the zone is the correct way to specify an impact window.

Energy Performance - Low-E insulated glass options are available for these double hung windows. In the Palm Beach Gardens climate, Low-E coatings reduce solar heat gain through the glass, which keeps west-facing rooms from baking in the late afternoon. Combined with an insulated glass unit, you get impact protection and better thermal performance in the same sash.

Color & Glass Options

The finishes we order most for Palm Beach Gardens homes are white and bronze, but almond, black, and tan are all available across the product lines we carry. White suits the coastal cottage and modern farmhouse styles common in neighborhoods like Evergrene and Canterbury Place. Bronze and black read more contemporary and pair well with darker roofs, bronze hardware, and homes with a Mediterranean or transitional lean. Almond and tan blend with the softer earth tones seen throughout older PGA National builds.

On the glass side, clear laminated impact glass is the budget-conscious starting point. Tinted glass adds glare control and reduces solar heat, which is valuable on east and west exposures. Low-E insulated glass is the energy-performance option: two panes with a sealed air space and a Low-E coating. If you’re replacing a full elevation and want to cut cooling load in a room that gets hammered by the afternoon sun, the insulated Low-E package is worth the step up. We’ll walk you through the tradeoffs on your quote.

Installation by TruePane Windows & Doors in Palm Beach Gardens

An impact window is only as good as the opening it’s set into. A Miami-Dade NOA approval covers the product, but the installation is a separate matter, and a poorly installed impact window will leak or perform below its rating. In Palm Beach Gardens, with our coastal exposure and the scrutiny of HVHZ inspections, the installation quality is not a nice-to-have. It’s the difference between a window that performs and one that fails when it matters.

Our process starts with a pre-install inspection. We check the existing opening, the rough framing, and the condition of the surrounding stucco or siding before ordering product. When the windows arrive, we set each unit level, plumb, and square. We follow AAMA 2400/2410 practice for installation, and we use AAMA 812 low-expansion foam to seal the perimeter. That foam is a specific product class, not generic spray foam from the hardware store. It won’t bow the frame, and it creates a dependable air and water seal. We finish with interior and exterior trim, a final water test, and a clean job site at the end of every day.

Permitting is part of the process. Palm Beach Gardens requires product approval documentation for replacement windows in the HVHZ wind-borne debris region. We handle the paperwork and know what the local building department looks for. If you’re in a community with architectural review, like Mirabella or Frenchman’s Creek, we also know how to prepare submittals that move through the review board without unnecessary delays.

Frequently Asked Questions - Double Hung Windows

What wind zone or design pressure is the double hung window rated for? The design pressure is matched to your specific wind zone, up to +/-100, and never higher. The exact number depends on your home’s location, building height, and the level of the opening. We confirm the rating for each window on your written quote so you’re not guessing at the permit counter.

What is the lead time? Lead times vary by manufacturer and configuration. Right now, the lines we carry are running at their typical seasonal pace, but larger openings or custom color selections can add time. We give you a realistic expected arrival date before you sign anything, and we schedule your install around it. Call (772) 794-8169 for current lead times.

Do I need a Miami-Dade NOA or Florida Product Approval submittal for my permit? Yes, if you’re replacing windows in Palm Beach Gardens or anywhere in Palm Beach County’s HVHZ jurisdiction. The building department will want to see proof that the specific product configuration you’re installing meets code. We include the correct approval documentation with your permit package.

Can I customize the size or configuration? Sizes are built to order within each manufacturer’s approved range. Custom widths and heights are available, but they must fall within the tested and approved envelope for that product line. If a stock size doesn’t match your opening, we’ll specify the closest approved custom dimension and confirm it’s covered by the product approval before ordering.

How do I maintain the frame? Rinse the frame and tracks with water a few times a year, especially if you’re near the Intracoastal or ocean. Salt air sits on aluminum and powder coat finishes. The tilt-in sashes make glass cleaning easy from inside. Lubricate the balance hardware with a silicone-based product if the sashes ever feel resistant. Vinyl and aluminum frames are both low-maintenance and don’t need paint or staining.
