Fifteen members of the Building Science Guild (BSG) attend the monthly meeting at the Windham Regional Career Center’s Construction/Architecture’s shop featuring Peter Yost’s “Wingnut Testing” experiment on roof venting. The purpose was to explore the appropriateness of a 1-inch code roof vent given variables of pitch, heat, and wind. Pete was in his element, racing from one section of the roof to another measuring airflow. Our comical wingnut hat was on display.
