Double hung impact windows offer the most ventilation flexibility available in a standard residential window configuration, with both the upper and lower sashes operable and designed to tilt inward for easy cleaning. America's Window and Door Store supplies and installs double hung impact windows throughout Broward County, providing homeowners with certified hurricane protection alongside a window that's practical and comfortable to use every day.
A double hung window has two independently operable sashes — both the upper sash and the lower sash slide vertically and can be opened to different positions for ventilation control. Unlike single hung windows where only the lower sash moves, double hung units allow simultaneous upper and lower sash operation, which improves cross-ventilation and air circulation throughout a room. Impact versions use laminated glass construction and reinforced frames certified to Florida's High Velocity Hurricane Zone wind-load requirements.
The tilt-in feature on double hung impact windows allows both sashes to pivot inward from the frame for cleaning from inside the home. This eliminates the need for exterior ladder access to clean upper-floor windows and makes routine maintenance significantly safer and more convenient. All double hung impact windows installed by America's Window and Door Store carry Miami-Dade NOA certifications accepted for Broward County building permits.
The defining advantage of double hung impact windows is their ventilation versatility. Opening the upper sash allows warm air near the ceiling to escape while the lower sash remains closed, which is particularly effective in South Florida kitchens, bathrooms, and living areas. Opening both sashes simultaneously creates a stack effect that improves natural airflow during the cooler winter months when running air conditioning is unnecessary.
Double hung impact windows also deliver the same full storm protection as any certified impact product — laminated glass that stays intact under debris impact and reinforced frames that hold under sustained hurricane-force winds. Additional everyday benefits include reduced solar heat gain for lower cooling costs, UV blocking to protect interior furnishings, and significant noise reduction compared to standard single-pane aluminum windows common in older Broward County homes.
The tilt-in sash design of double hung impact windows is one of the most practical features for South Florida homeowners. Both the upper and lower sashes tilt fully inward, allowing the exterior glass surface to be cleaned from inside the home without ladders or exterior scaffolding. For second and third-floor installations, this feature represents a meaningful long-term safety and convenience benefit that homeowners appreciate on every cleaning day.
Double hung impact windows in vinyl or aluminum frames require minimal ongoing maintenance in South Florida's coastal climate. The frames don't need painting, resist salt air corrosion, and clean easily with standard household products. The laminated glass construction also eliminates the fogging issues that develop in older standard insulated glass units over time in South Florida's humidity.
The primary difference between double hung and single hung impact windows is that double hung units have two operable sashes instead of one. This provides more ventilation options and tilt-in cleaning convenience on both sashes, but comes at a higher per-unit cost due to the additional hardware and more complex frame construction. For homeowners where easy cleaning and flexible ventilation are priorities, the added investment is well justified.
For projects where budget efficiency across a large number of openings is the primary concern, single hung impact windows deliver the same storm protection at a lower per-unit price. Many homeowners choose a mixed approach — double hung in primary living areas and bedrooms, and single hung in utility spaces where those features are less critical. Our team helps you think through the right configuration for each opening during the free estimate visit.
America's Window and Door Store offers double hung impact windows in aluminum and vinyl frame profiles with a range of color options including white, bronze, and custom finishes. Frame selection affects both aesthetics and long-term performance — aluminum frames are dimensionally stable and well-suited to larger openings, while vinyl frames offer excellent thermal performance popular in Broward County's residential market.
Glass package options include standard clear laminated glass, tinted glass for reduced solar heat gain, and low-e laminated glass that provides the best combination of visible light transmission and thermal performance. Our team helps customers select the right glass package based on each home's orientation and sun exposure, which can make a measurable difference in cooling costs throughout South Florida's extended summer season.
