The basic equation for heat conduction through a wall is: Q = K(ΔT)/L where Q = heat transfer, in J/hr/m² of wall K = conductivity, in J-m/m²-°C-hr ΔT = difference in temperature between the two surfaces, in °C L = thickness of insulating material, in meters Which insulation material should be selected?
