​​​Double-Hung Windows

A double-hung window is a classic and versatile window design commonly found in homes and buildings. This type of window features two sashes, or panels, that can move vertically within the frame. Both the top and bottom sashes are operable, meaning they can be opened to allow for ventilation. The top sash can slide down, while the bottom sash can slide up, providing flexible airflow options.

One of the key benefits of double-hung windows is their ease of cleaning. Many models allow the sashes to tilt inward, making it convenient to clean both the interior and exterior surfaces from inside the home. Additionally, double-hung windows are known for their energy efficiency, especially when fitted with modern weatherstripping and high-performance glass.

Ideal for various architectural styles, double-hung windows offer a timeless look combined with practical functionality, making them a popular choice for both new construction and renovation projects.

​Benefits of New
Double-hung Windows

  • Enhanced Ventilation: Double-hung windows allow both the top and bottom sashes to open, enabling better airflow. You can open the upper sash for warm air to escape and the lower sash for cool air to enter, creating effective natural ventilation.

  • Ease of Cleaning: Many double-hung windows feature tilt-in sashes, allowing you to clean both the interior and exterior glass from inside your home, which is especially convenient for upper-story windows.

  • Improved Safety: By opening only the upper sash, you can maintain ventilation while keeping the lower sash closed, making it a safer option for homes with children or pets.

OneSource was so competent though, it was worthwhile, and fairly painless. They kept all their commitments. They followed up regularly. I always knew the status of my order. The price was fair and it was overall, a really nice and super competent team. The new sliding doors are wonderful! Such an improvement!
