Our Founder


Wayne Jack

November 16, 1939 – October 30, 2014

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 thought differently – and his vision proved spectacularly right.

Wayne always credited 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. Following his retirement in June 2004, Wayne continued to reside in Western Canada.

Wayne passed away in Edmonton Alberta on October 30, 2014, aged 74. He was father to six children and, at the time of his passing, eight grandchildren and a great-grandson. Throughout his life, Wayne was a builder of partnerships and friendships, and valued the many people he met throughout his lifetime. Winroc’s people were saddened over his loss, and will always remember Wayne with respect and affection.
