Double-Hung Windows Defined

Double-hung, also known as double-sash, are rectangular windows similar to single-hung designs. The difference with double-hung windows is they consist of two operable sashes, top and bottom, instead of only one operable bottom sash. The ability for both sashes to open provides superior ventilation and an added level of safety for homeowners with small children.

Double-Hung Window FAQs

What’s the difference between a double-hung window and a single-hung window?

The primary difference between a single-hung and double-hung window is the operable sashes. While both the top sash and bottom sash of a double-hung window are operable, a single-hung window only has one operable lower sash.

Why do people like double-hung windows?

The primary reason homeowners enjoy double-hung windows is the additional airflow and ventilation the two operable sashes provide compared to a single operable sash while also being significantly easier to maintain.

Why are double-hung windows more expensive?

Several factors lead to the price difference between single and double-hung windows, including window size, materials, energy efficiency, optionality, UV protection, operable parts, and installation complexity.

What makes double-hung windows an excellent choice for families with small children?

Families with small children choose double-hung windows because they provide locks and latches that prevent accidental openings. Their design also allows you to open the top sash for ventilation while keeping the window opening out of a child’s reach. Additionally, their durability ensures they can withstand the occasional bumps and knocks that come with kids’ activities.

Are double-hung windows the same as double-pane windows?

No, double-hung windows and double-pane windows are not the same. Double-hung windows have two sashes that can be moved up and down, whereas double-pane windows have two panes of glass sealed together to provide improved insulation. In other words, “double-pane” refers to the glass used, while “double-hung” refers to the window design.

Why does a double-hung window cost more than a single-hung window?

Double-hung windows generally cost more than single-hung windows due to their more complex design and additional functionality. While single-hung windows are more straightforward and have a single operable sash, double-hung windows offer increased functionality. The manufacturing process and hardware required for the dual sashes contribute to the higher cost, as does the added convenience of being able to tilt both sashes for easy cleaning.
