In the above example, the wall consists of 4" brick + 0.25" cement plaster + 2 plaster boards of 0.5" width and 2" airgap. The overall conductance is 0.28 while the unit weight of this composite wall is around 40 lb/ft^2. The program has standard default values for each type of wall material that can be edited using the properties button for better approximation. Upon clicking OK button these values get posted and used for computation of the heat gain through walls. |
