... The thermal resistivity of wood is R2 = d2 × 2.5 (ft2-°F-hr/Btu)/inch, where d2 is the thickness in inches. Since d2 = 1 inch, R2 = (1 in) × 3.2 (ft2-°F-hr/Btu)/inch = 2.5 ft2-°F-hr/Btu. The sheet rock has negligible insulating effect. Therefore the total thermal resistivity is Rtotal = R1 + R2 = 1 ...
