(a) Calculate the R-value of a thermal window made of two single panes of glass each 0.100 in. thick and separated by a 0.200-in. air space.

(b) By what factor is the transfer of energy by heat through the window reduced by using the thermal window instead of the single-pane window? Include the contributions of inside and outside stagnant air layers.
