The floor of the basement described in Problem 5-28 is finished with a thin vapor barrier, in. (16 mm) particle-board underlaymcnt, and carpet with rubber pad. Estimate an overall heat-transfer coefficient for the floor. Problem 5-28 A 24 x 40 ft (7.3 x 12.2 m) building has a full basement with uninsulated walls extending 5 ft (1.5 m) below grade. The insides of the walls are finished with R-8 (R-0.7) insulation, a thin vapor barrier, and in. (12.7 mm) gypsum board. Estimate an overall heat-transfer coefficient for the walls.
