In the first, written in 1972, J.R. Sasaki of the International Research Council of Canada concluded that metal stud wall R-values were 9 to 13 percent less than the R-value as calculated by the ASHRAE Zone Method. Roof must be complete before framing inspection. Maximize The Benefits Of Energy Efficient The question-and-answer article about the thermal properties of metal stud-framed walls, quotes-from, updates, and comments an original article from Solar Age Magazine and written by Steven Bliss. See INSULATION R-VALUES & PROPERTIES and see HEAT LOSS R U & K VALUE CALCULATION) of individual elements to calculate the thermal resistance of a multi-component system such as a stud wall. ASHRAE Design Guide, Advanced Energy Design Guide for K-12 School buildings, 6/11/2008, This is an ASHRAE Design Guide. -- S Bliss. We include test data giving effective R-values for nominal 2x4 and 2x6 metal stud walls. Metal stud thermal short-circuiting studies and heat loss data. The discrepancy, they speculate, was due to increased lateral heat flow through the flanges of the metal stud.
