Double Hung Windows

Double hung windows have two operable sashes that both move up and down, while single hung windows have a fixed top sash with only the bottom sash operable. The dual operation of double hung windows provides superior ventilation control and cleaning convenience. Most homeowners prefer the added flexibility that double-hung windows offer.

Modern double hung windows have sash releases that allow you to tilt both the upper and lower sashes inward for cleaning exterior glass surfaces. Simply unlock the tilt latches, pivot the sash inward, and clean both sides from inside your home. This feature eliminates the need for ladders or exterior access for routine window maintenance.

Contemporary double hung windows with quality glazing, weatherstripping, and proper installation deliver excellent energy efficiency ratings. Advanced features like Low-E glass coatings, argon gas fills, and insulated frames minimize heat transfer. Our double hung windows meet or exceed ENERGY STAR requirements for all climate zones.

Quality double hung windows professionally installed by Window & Door Professionals last 20 to 30 years or more with basic maintenance. The longevity depends on material quality, operating mechanism type, and environmental conditions. Our warranties provide long-term protection for your window investment.

Modern double hung windows use either constant force balance systems with coiled springs or block and tackle systems with cords and pulleys. Constant force balances provide smoother operation and require less maintenance over time. We install balance systems engineered to support your specific window sizes without failure.

Properly sized double hung windows with adequate opening dimensions meet building code egress requirements for bedrooms and basements. The window must provide a sufficiently clear opening area and meet minimum height and width specifications. We ensure bedroom windows comply with all applicable egress regulations.

Vinyl frames offer excellent insulation, low maintenance, and affordability for double-hung windows. Fiberglass and composite options provide enhanced durability and strength for larger window sizes. We help you select frame materials that align with your performance expectations and budget parameters.

Double-hung windows need periodic cleaning of glass surfaces and tracks to maintain optimal operation. Lubricating balance systems and hardware with silicone spray annually ensures smooth sash movement. Checking and replacing weatherstripping as needed maintains energy efficiency over the window’s lifespan.

Double hung windows can provide up to 50% ventilation when both sashes are opened halfway. The ability to open from top and bottom creates natural convection that efficiently circulates air. This ventilation capability makes them effective for temperature regulation and indoor air quality.

Double hung windows feature sash locks at the meeting rail that secure both sashes when closed. Many models include additional security features like cam locks or keyed locks for enhanced protection. The dual sash design with multiple locking points provides reliable security when properly engaged.
