Proto Labs, a Minnesota-based manufacturer of custom parts for prototyping, acquired the Plymouth Industrial Building with plans of renovating the building including more than 170,000 square feet of new roof. A reliable, durable roofing system was important to Proto Labs, and GenFlex EPDM was selected based on the roofing contractor’s history of positive experiences with GenFlex. Since project completion in April 2014, GenFlex EPDM now protects Proto Labs’ high-end computerized equipment, 180 injection molding systems and 425 CNC machines, all under one roof.
