When 20 year old Harold Warp chugged his Model T into Chicago from the Nebraska farmlands in 1924 with a patent for Flex-O-Glass® and $800 in his pocket, his hope for the future lay in a special window material he had developed for his family’s chicken coops, a desire for success and a willingness to work hard.

A storefront factory/living quarters on Chicago’s unpaved Cicero Avenue provided the start of FLEX-O-GLASS® and WARP BROTHERS. Today the firm has grown to fill three large plants and place the company among the leaders in the plastics industry.
