Our classic double hung windows have two movable sashes, allowing you to easily control ventilation. The bottom sash slides up while the top sash slides down. This traditional style is available with a wide range of custom options. The double hung windows also keep out drafts and weather while letting air flow through screens. Built to last, these windows feature quality materials and craftsmanship. A double hung window will provide superior functionality, energy savings and classic styling for your home.
Double hung window gets its name from the feature of having two window sashes, an upper and a lower, that both slide up and down vertically within the window frame. Cord and pulley systems allow easy lifting and lowering of the two panes independently to customize ventilation.
While traditionally made of wood, contemporary double hung windows utilize durable vinyl, composite, or fiberglass frames along with energy-efficient insulating glass to withstand weathering.
A drawback is that the sash and track system of double hung windows leaves slightly less overall glass area compared to other operable styles. The moving panels limit outward visibility and natural light entry.
Additionally, years of frequent use can lead to issues like frayed pulley cords and off-track operation. Proper installation and periodic maintenance is key for optimal performance.
Single hung windows only enable the bottom window sash to slide upward vertically while the top section remains fixed in place. Double hung means that both the top and bottom sash components can independently slide and operate.
This allows superior control over a wider range of adjustable ventilation needs compared to the limitations of single hung models.
High-quality double hung windows demand complex engineering to allow two movable sashes within an integrated frame, requiring specialized hardware and precision manufacturing.
Also, multi-layered fused glass drives up cost significantly. While vinyl, composite, and fiberglass hold up better in weather than plain wood, these durable materials are more expensive. The unparalleled longevity and energy savings make the investment in double hung windows worthwhile.
Casement windows generally outperform double hung windows in maximum air tightness and ventilation airflow made possible through the outward side-hinged opening operation. However, double hung windows’ classic divided lite style fits in well with more home architectural types.
Carefully consider location and surrounding features when selecting replacement windows, since both casement and double hung come in energy-efficient models to meet efficiency standards.
Yes, investing in durable, ENERGY STAR certified double hung window replacements boosts property value far more than old inefficient units.
Modern double hung windows cut utility bills substantially, while visually enhancing exterior curb appeal with attractive grid patterns. Smooth and reliable operation for decades also appeals greatly to prospective home buyers. Upgrading pays dividends come resale time.
