Double Hung Basics
Double hungs are the most popular style of window around, right up there with slider and picture windows. The window consists of two sashes, one on the top and one on the bottom, both of which can be opened. The result is a very versatile and functional window that often gets good performance numbers relative to other styles. Many consumers like the look of double hungs with the more vertical or up and down shape (compare to sliders that are typically more horizontal).
