I just purchased a house that was built and finished this year.
My house is backed up to a hill, and the foundation walls get shorter from the front of house (8 feet) to the back (a little over 2.5 feet), with above ground windows. There is foil type installation around the wooden wall areas and a white blanket around cement areas about halfway down the wall from start of foundation at top. The back area where the foundation is only 2.5 ft tall there is no white blanket installation. Just the foil type covering with pink installation around the above ground area and around windows.
Should there be insulation around the cement for this shallow area too? I live in Illinois, an hour from Chicago.
