A wall is made up of the following materials. Given the associated thermal resistance (R-value) for each material, calculate the U-factor for this wall. Thermal resistance hr. ft? . °F/Btu [m². K/W] outdoor-air film resistance (summer) 0.25 (0.044) 4 in. (100 mm] face brick 0.80 [0.141] permeable-felt vapor membrane 0.06 (0.011] 5.5 in. (140 mm) fiberglass insulation 21 [3.67] 0.5 in. (12.7 mm) gypsum board 0.45 (0.079] indoor-air film resistance 0.68 [0.12]
