what is a single hung window

A single hung window is a type of window that has a fixed top sash and an operable bottom sash that moves vertically. This means that the bottom part of the window slides up and down, while the top part remains stationary. Single-hung windows provide ventilation through the bottom sash. They are simpler to construct than double-hung windows, which is reflected in the price. Mixing single- and double-hung windows throughout your home is a great option, choosing one over the other depending on your needs.
