Determine the summer R value and the U-factor of a wood frame wall that is bujflt around 38-mm × 140-mm wood studs with a center-to-crater distance of 400 mm. The 140- mm-wide cavity between the studs is filled with mineral fiber batt insulation. The inside is finished with 13-mm gypsum wallboard and the outside with 13-mm wood fiberboard and 13-mm × 200-mm wood bevel lapped siding. The insulated cavity constitutes 80 percent of the heat transmission area, while the studs, headers, plates, and sills constitute 20 percent. Answer; 2.213 m2 K/W, 0.311 W/m2·K
