In Reply to: insulation of concrete block walls posted by David Kauffman on May 05, 2003 at 11:11:18:
: I have a home built in the 40s with hand made block walls. There is no insulation in the walls. What product could I use to fill into the blocks to insulate the house. I have been told there is a very fine product used to sift between the blocks.
