WASCO Windows opened in Milwaukee in 1957 as Wisconsin Aluminum Supply Company, and was purchased by Dave Paulus in 1983. At that time, the company manufactured aluminum storm windows, siding and awnings. Under Paulus’ direction WASCO became the first company in this area to manufacture then-new vinyl replacement windows. Since 1983 the Paulus family has transformed WASCO into a company that leads the industry in manufacturing and installing highly energy efficient window products, engineered for Wisconsin’s unique climate.
