Double Hung Windows

Double Hung Windows in Sarasota, FL | TruePane Windows & Doors

Double hung windows are the classic Florida workhorse, two sashes that slide vertically so you can open the top, the bottom, or both at once. Here in Sarasota, the version that actually makes sense is the impact-rated kind: laminated glass, reinforced framing, and hardware that holds its geometry through a storm. TruePane Windows & Doors installs these across our PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, always to AAMA 2400/2410 practice with the perimeter sealed tight. If you’re pricing replacement windows for a Sarasota home, call (941) 214-2069 and we’ll give you written numbers with the NOA documentation to back them up.

Product Overview - Double Hung Windows

Double hung windows give you something casements and fixed picture windows can’t: airflow control from two directions. The lower sash lifts for the breeze, the upper sash drops to vent heat that collects near the ceiling. In a Sarasota summer, that matters more than most people expect. And when a storm approaches, both sashes lock flush into the frame, and the laminated impact glass does the work a shutter used to do.

The design is traditional enough that it reads correctly on Florida ranch houses, Mediterranean revival homes, and coastal cottages alike. You keep the familiar vertical proportions, the meeting rail in the middle, the tilt-in convenience for cleaning, but you get glass engineered for high-velocity hurricane zones. Both sashes tilt inward, so second-story windows get cleaned from inside the house, not from a ladder leaned against stucco.

The frames come in aluminum or vinyl. Aluminum gives you thinner sightlines and more visible glass area, which matters on larger openings. Vinyl gives you a tighter thermal break and a softer look that suits certain architectural styles. Both get the same laminated glass treatment. We’ve installed hundreds of these in Sarasota neighborhoods, from Siesta Key condos to older homes west of the Trail, and the product holds up well in the salt air when the finish is specified correctly.

Technical Specifications

• Frame materials: Aluminum or vinyl, chosen for the opening size and the home’s architecture.
• Glass options: Laminated impact glass with PVB interlayer, Low-E insulated glass, tinted glass, clear glass.
• Finish colors: White, almond, bronze, black, tan, matched to interior and exterior trim where specified.
• Screen options: Half screen for partial opening ventilation, full screen for full-opening airflow.
• Design pressure: Matched to your Sarasota wind zone, rated up to +/-100 psf. We never push a window beyond what its specific configuration is approved for.
• Compliance documentation: Miami-Dade NOA and Florida Product Approval numbers available per configuration. Every unit we sell in Sarasota gets the approval package that matches its exact size, glass, and frame combination.

Hurricane & Compliance Performance

Laminated Impact Glass (PVB Interlayer)
Two panes of glass bonded to a polyvinyl butyral interlayer. Under impact, the glass fractures but the interlayer holds the pieces in the frame, keeping wind and water out. This is the same principle used in automotive windshields and the same protection a shutter provides, minus the labor of wrestling panels into place before a storm.

Miami-Dade NOA / Florida Product Approval
Every configuration gets its own approval number. That matters in Sarasota because the building department wants to see the specific NOA for your specific window, not a generic line sheet. We pull the right documents for your exact sizes and options, so the permit submittal doesn’t stall.

FBC High-Velocity Hurricane Zone Compliance
Sarasota sits inside the HVHZ designation, which changes what you can legally put in an opening. These units are engineered to Florida Building Code requirements for high-velocity hurricane zones, which means they meet the impact and structural standards the code expects for this region.

TAS 201 / TAS 202 / TAS 203 Testing Context
TAS 201 is the large-missile impact test, TAS 202 is cyclic wind-pressure loading, TAS 203 is forced-entry resistance. Together they form the test family HVHZ-rated products go through. These windows come from manufacturers that build to that protocol, and we verify the paperwork on every Sarasota installation.

Design Pressure Matched to Your Wind Zone
Design pressure is the psf rating the window sustains under load, not an mph wind-speed figure. We match the DP rating to your specific wind zone, up to +/-100 psf, and never higher than the approved configuration allows. Coastal exposure, elevation, and opening size all factor into what gets specified.

Low-E / Insulated Glass Options
For Sarasota sun, low-E coatings cut solar heat gain without darkening the glass. Insulated glass adds a thermal break and quiets the room. These aren’t impact replacements, they’re coatings and airspaces added to the laminated impact assembly, so you keep the storm protection and gain energy performance.

Color & Glass Options

For Sarasota homes, finish selection tends to break along architectural lines. White and almond suit ranch styles and older Florida block homes where the trim is painted light. Bronze and black read sharper on mid-century modern or contemporary builds and hide the visual weight of the frame on larger glass areas. Tan works when the home has a warmer stucco palette or Mediterranean detailing. For coastal properties with salt exposure, powder-coated finishes on aluminum hold up better than uncoated surfaces.

Glass choice depends on what the room needs. Clear laminated glass preserves the truest view and the most natural light, which matters on gulf-front elevations. Tinted glass cuts glare on west-facing rooms that bake in the afternoon. Low-E insulated glass is the pick for bedrooms and living areas where the air conditioner runs constantly. Tinted and low-E can be combined on the right configuration, and we’ll show you samples before you commit.

Installation by TruePane Windows & Doors in Sarasota

An impact window is a system, and the system is only as good as its weakest connection. A correctly manufactured double hung with an NOA can leak and fail if it’s set out of square, shimmed wrong, or sealed with whatever foam happened to be on the truck. That’s why we treat installation as a process, not an afterthought.

Every project starts with a pre-install inspection of the rough opening, the existing flashing condition, and the wall cavity. We check for water damage or rot in older Sarasota homes, because once the old window is out, whatever’s behind it is now the substrate your new window attaches to. We set units level, plumb, and square, then seal the perimeter with AAMA 812 low-expansion foam, which is designed for fenestration and won’t bow the frame the way construction foam can. The work follows AAMA 2400/2410 practice, which covers the full sequence from shimming to flashing and interior trim, and we finish with a water test before we call the job done.

Sarasota’s coastal wind zones and the permitting requirements that go with them mean the paperwork matters as much as the window. We provide the Florida Product Approval or Miami-Dade NOA documentation with every quote, because your permit application will need it. If the building department asks for additional detail, we handle the response. What we don’t do is sell a window without knowing it’s approved for the opening it’s going into, and that’s a bigger deal in HVHZ territory than most homeowners realize.
