In order to increase the thermal resistance of a typical exterior frame wall, it is customary today to use 2 × 6 studs instead of 2 × 4 studs to allow for the placement of more insulation within the wall cavity. A typical exterior (2 × 6) frame wall of a house consists of the materials shown in Figure P5.13. Assume an inside room temperature of 68oF, an outside air temperature of 20oF, and an exposed area of 150 ft2 . Determine the heat loss through this wall.
