4. Objective 1. Wallboard Testing: The purpose of this series of experiments The purpose of this series of experiments was to determine the heat transfer was to determine the heat transfer coefficient and associated R-value for coefficient and associated R-value for standard ½” composite wallboard standard ½” composite wallboard 2. Group: Our objective was to evaluate the Our objective was to evaluate the problems associated with testing and suggest problems associated with testing and suggest a more appropriate test method a more appropriate test method
