Abstract
In general, light gauge steel framed walls are comprised of various materials which include steel studs. The steel stud causes thermal problems such as the thermal bridge. Therefore, It is complicated to calculate the thermal performance of steel stud framed wall systems and there are some errors between calculation and measurement. In such circumstances, this research aims at predicting the thermal performance of steel framed walls through calculations and experiments of steel stud framed wall systems according to a wall composition. As a result, the prediction equation was extracted from regression analysis methods. The average error ratio between the predictions and the measurements was -3.61%.
