Double Hung Windows in Westchester, FL | Winslow Windows & Doors
Double hung windows are the classic vertical-glide design so many Westchester homeowners grew up with, but ours are built for Florida, not for a house in Ohio. Both sashes tilt in for easy cleaning, and the laminated impact glass does the serious work of holding the window together when a storm throws debris at it. Winslow Windows & Doors supplies and installs impact-rated double hung windows across PGT, CGI, CWS, ES Windows, ECO, and Mr-Glass lines, so you get the right configuration for your home’s wind zone, not a one-size-fits-all box. If you’re replacing old single-pane windows or building new in Westchester, call us at (863) 251-5864 to talk through your project and get a free estimate.
Product Overview - Double Hung Windows
Double hung windows are easy to spot: two sashes, one upper and one lower, both of which slide vertically in the frame. That traditional profile is a big reason they remain the most common replacement window in Florida neighborhoods. They read as familiar. They fit the architectural language of 1950s ranch homes in Westchester as naturally as they fit newer Mediterranean-style builds. But beneath that familiar profile, the impact-rated version is a completely different animal from the windows those older homes were built with.
The frame is available in aluminum or vinyl, both engineered to carry laminated impact glass and hold its shape under forced entry and cycling wind pressure. The sashes tilt inward on both the top and bottom, so cleaning second-story windows from inside the house is a two-minute job, no ladder required. That tilt-in function also makes glass replacement simpler down the road, though with laminated impact glass, you’re unlikely to need it for anything short of a direct large-missile hit.
In Westchester, the reason people choose impact double hung windows over standard single hung or fixed windows usually comes down to two things: code compliance and insurance. The Florida Building Code High-Velocity Hurricane Zone requirements apply to most of the region, and a properly rated double hung window with Miami-Dade NOA documentation satisfies those requirements without forcing you to put shutters over every opening. That means protection that’s always there, whether you’re home or not.
Technical Specifications
- Frame materials: Aluminum or vinyl, selected per project for weight, finish durability, and structural requirements.
- Glass options: Laminated impact glass with PVB interlayer, Low-E insulated glass, tinted glass, or clear glass.
- Finish options: White, almond, bronze, black, and tan.
- Screen options: Half screen or full screen, sized to match each configuration.
- Design pressure: Matched to your specific Westchester wind zone, up to +/-100 PSF. We never engineer a window beyond what the code requires for your structure, and we never charge you for over-engineering you don’t need.
- Compliance documentation: Miami-Dade NOA and Florida Product Approval numbers issued per configuration and verified on your written quote.
- Testing family: Evaluated under the TAS protocol suite for HVHZ-rated products, including TAS 201 large-missile impact, TAS 202 cyclic wind-pressure loading, and TAS 203 forced-entry resistance.
Hurricane & Compliance Performance
- Laminated Impact Glass - Two panes of glass are bonded to a PVB (polyvinyl butyral) interlayer. When a branch or roof tile strikes the outer pane, the glass cracks but stays adhered to the interlayer and remains in the frame. The storm stays outside. That’s the whole point.
- Miami-Dade NOA / Florida Product Approval - Every configuration we quote carries the appropriate Notice of Acceptance or Florida Product Approval number. These are issued per specific size and frame combination, so we verify the exact documentation on your quote before anything gets ordered.
- FBC / HVHZ Compliance - This window is engineered to Florida Building Code High-Velocity Hurricane Zone requirements. If your Westchester property sits in an HVHZ jurisdiction, this is the compliance path your permit reviewer expects to see.
- TAS 201 / 202 / 203 Testing Context - HVHZ-rated products are tested under a family of protocols: TAS 201 covers large-missile impact, TAS 202 covers cyclic wind-pressure loading, and TAS 203 covers forced-entry resistance. Our supplied windows carry documentation through this testing family.
- Design Pressure for Your Wind Zone - Design pressure is not a wind speed. It’s a PSF rating that accounts for where your home sits and what the building code requires at that location. We match design pressure to your wind zone, up to +/-100 PSF, and never push beyond it.
- Energy Performance - Low-E and insulated glass options are available for homeowners who want impact protection and solar heat management in the same unit. In Westchester’s hot afternoons, a Low-E coating does meaningful work reducing heat gain through west-facing glass.
Color & Glass Options
The finish on your double hung windows should do two things: hold up under Florida sun, and look like it belongs on your house. White is the classic default and reads clean on nearly every Westchester home, from older concrete-block construction to newer builds. Almond and tan warm up the facade and work especially well on Mediterranean or Spanish-influenced homes with stucco exteriors. Bronze and black have grown popular on modern and transitional properties where homeowners want a stronger frame line against light walls.
Glass selection follows the same logic. Clear laminated impact glass is the practical standard: full protection, no tint, maximum natural light. Tinted glass cuts glare and solar heat without changing the window’s outward appearance dramatically. Low-E insulated glass adds a thermal performance layer, pairing the impact-rated outer lite with an insulating airspace and a low-emissivity coating. It’s the option we recommend for bedrooms and west-facing rooms in Westchester where afternoon heat loads are highest.
Installation by Winslow Windows & Doors in Westchester
An impact window is only as good as the opening it’s sealed into. A NOA-rated double hung installed with gaps, shims that shift, or sealant that fails under cycling wind pressure is a leak waiting to happen, and it compromises the entire protection system. That’s the honest reason professional installation matters. The documentation says the window passes test protocols in a controlled lab; the field installation determines whether it performs that way on your house for the next twenty years.
Our process in Westchester starts with a pre-installation inspection of the existing opening. We check the rough opening dimensions, framing condition, and any signs of moisture damage or rot before we order anything. On install day, every unit goes in level, plumb, and square. We use AAMA 812 low-expansion foam perimeter sealant to seal the full perimeter, then follow AAMA 2400/2410 installation practice for flashing and integration with the wall system. That’s the standard we install to, on every window, on every job.
Westchester properties carry coastal exposure considerations and HVHZ wind zone requirements that change from street to street. We’re familiar with the local permitting flow, the product approval submittals reviewers ask for, and the inspection points that matter. After installation, we run a water test on the opening, clean the site, and walk you through the finished work. If the window doesn’t operate smoothly at final walk-through, we don’t call it done.
Frequently Asked Questions - Double Hung Windows
Design pressure is matched per project to the wind zone your Westchester home falls under, up to +/-100 PSF, and never higher than your structure requires. The specific DP rating appears on your quote along with the Miami-Dade NOA or Florida Product Approval documentation for your exact configuration. Call (863) 251-5864 and we’ll confirm your zone before anything gets ordered.
Lead times run several weeks depending on the manufacturer, glass package, and finish you choose. Custom sizes and less common color options can push that longer. We confirm a realistic delivery window at the time of your quote, so you’re not surprised later. Call (863) 251-5864 to get a current estimate for your configuration.
In most Westchester HVHZ jurisdictions, yes. The building department will want to see the product approval documentation matching the exact sizes and configurations being installed. We handle that submittal, and every quote from Winslow Windows & Doors includes the specific NOA or FL Product Approval numbers for the units we’re supplying. No generic documentation, no “close enough” paperwork.
Double hung windows are manufactured to order within manufacturer-permitted size ranges. If your opening falls outside what a given manufacturer can produce in a double hung configuration, we’ll tell you before you spend money, and we’ll show you alternatives that still meet code. Heights, widths, grid patterns, and glass packages are all selected per opening during your estimate.
Both vinyl and aluminum frames clean with mild soap and water, and the tilt-in sashes on both top and bottom mean you can reach every glass surface from inside the house. The balance system and tilt hardware should be inspected annually, and tracks kept clear of sand and debris. Coastal air in Westchester can be rough on hardware, so a quick rinse of the tracks a few times a year goes a long way.
