MW Windows & Doors, a brand of Ply Gem Windows Group, is a leading manufacturer of window and door products for the residential construction industry. Founded in 1939, MW was one of the first window companies in the country to build a window and frame together as a single unit ready for installation into a rough opening. During World War II, MW interrupted its window operation to manufacture ammunition boxes for the war effort. Soon after the war ended, MW resumed its window manufacturing.

In addition to Rocky Mount, MW has operations in Fayetteville, N.C., Tupelo, Miss. and Hammonton, N.J.
