double-hung windows: The most popular window style, which has an upper and a lower sash that move vertically in separate channels. The sashes are separated by a small piece of wood called a parting strip; the upper and lower sashes also have meeting rails that helps keep the seal tight between the rails.

There are two different kinds of dropped patterns: half-drops and multiple drops.
