The wall shown in the figure consists of seven layers arranged in series. The thermal
resistances of these layers in (m^2.K)/W are given below:
Red Brick = 0.1
Air Cavity = 0.25
Polystyrene insulation 0.35
Concrete Masonry Units 0.2
Cement Plaster = 0.03
Gypsum Board = 0.14
Latex Paint = 0
Take the emissivity of the interior surface as 20%, and calculate:
