R - value measures the effectiveness of insulators what R-value should we use for walls? Ceilings?
R-value for walls = R-19 R-value for ceilings = R-30 to R-44
If both have the same temperature, which has more thermal energy… a cup of water or a lake
The lake because it has more mass, thus more thermal energy!
