Double-glazed windows are usually made of two glass panes with a thin layer of air sealed between the panes. a. Why do these windows reduce heat loss to a much greater extent than occurs if the double glazing is replaced by a thicker glass instead? b. Why does the insulating effect of the double glazing decrease if the two glass panes are too far apart? Explain.
