Home insulation question
I own a small 1939 cape. There is no insulation in the walls. For whatever reason the home was built (1938 hurricane?) like a bomb shelter. The walls are 3/4 inch thick of dense plaster-like cement.
Question: Is blow-in insulation worth it or a waste of time? How do you know if the insulation gets blown in uniformly--or does it just build up wherever it hits wood?
