Calculate the heat loss from a double-pane-glass window consisting of two pieces of glass, each having a thickness of 10 mm with a thermal conductivity of k = 1.3 W/m·k . The two glass-panes are separated by an air gap of 7 mm. Assume thermal conductivity of air to be k = 0.022 W/m·k . Also, express the total R and U values in both SI and U.S. customary units.
