Gosh! It’s 103 and HOT! What is the best way to insulate concrete block walls on a 35 year old house? The walls are empty hollow block. Can I knock a hole at the top of each cavity and fill with vermiculite? (If this is a way, what is the best way to do it?) Is there something else more hi-tech (foam, etc) that would do a better job. I do not want to add studs inside and insulate with fiberglass nor put “styrofoam” and stucco on the outside.
