American Agra Curtains, a manufacturer of textile products for livestock barns, particularly insulated curtains for swine, dairy and poultry operations, was founded in 1983 by Bill and Carolyn Henderson. While Bill, who was at the time a builder of livestock facilities, constructed structures throughout the midwest, Carolyn began to offer her expertise as a seamstress to begin making the curtains for those facilities.  At the beginning, Carolyn made the curtains on the couple’s front porch. To measure the length, which can often be hundreds of feet long, the curtains were stretched out in the road in front of the couple’s house. The Hendersons received a patent for their insulated curtain, named Mar-Co-Lite, in 1984.
