Our Founder
Wayne Jack
Winroc was founded by Wayne Jack in Winnipeg, Manitoba in 1971. He came up with the name, “Winroc” at his kitchen table by combining “Winnipeg” and “gyproc.” At the time, gyproc drywall was a relatively new product – and many believed it would never replace lath and plaster walls. Wayne credits Winroc’s success to entrepreneurial people, a corporate structure that allowed the people who work with customers to make decisions, and creating the Allroc buying group to gain access to products and suppliers.
Wayne retired from his role as Winroc’s Chairman in June 2004. He currently resides in the town of Qualicum Beach on Vancouver Island.
