Is it worth the added cost ?

I think that adding foam to a block wall would be a waste of money. First of all, many of the fillable cells will not get any foam because of the excess mortar, steel rebar, wire mesh, and other junk that will prevent access for the foam to get in. Masonry installers use a lot of mortar and much of it gets into the cell voids. The foam insulation value will be minimal. And, secondly, it will not provide any sound proofing because the sound will travel directly around the foam and through the concrete webbing.
