An insulating wall is constructed with two layers of 250 mm thick Plywoodseparated from each other with a 16 mm thick foam. Thermal conductivity of the Plywoodand foam are 2.69 W/m.K and 0.034 W/m.K, respectively. For a temperature drop of 31.2 K, calculate the heat loss for the 5m x 4m wall. (neglect the effect of convective heat transfer between both sides of the wall.

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.
