On hot days we often pull the shades on windows to keep the sun out and heating down. Yesterday we had a big dip in temperature. Typically these days the night temp is around 66-70. It was near to 50. Last night my wife pulled down all the shades to keep the heat in. Somehow I don't think this is as effective as keeping the heat from the sun in. Comments?

Air between shades and window acts as a thermal insulator.
