An open house that put about two dozen United Building Supply contractors together with several vendors, as well as a 3.5-credit continuing education class, turned into a big win for everyone. The open house, held at Breaking Bread in Sheboygan, was the first time in several years that UBS has provided an opportunity for contractors to get the educational credits they need. The educational component was led by Tom Harris of OSI sealant. As part of the course, volunteers from the class took a turn using OSI caulk on a window and also worked together to install a sliding patio door in a temporary frame.
