My house was built in 1943. I have 8 inch thick masonry walls of 6 inch structural clay tile with a 4 inch brick face that is bonded to the tile with brick laid so as to extind into the clay tile. The inside has 3/4 firring strips, rock lath and paster.
The problem? My walls are cold.
Does anyone have experience with vermiculite? I’m thinking that if I pour it from the top of my walls, I could fill the clay tile. I thought I herad something about it being banned, but I’ve recently seen it for sale at one of the big boxes.
Would it work? Would it cause any damage? any moisture problems? any other problems?… Or does anyone have a better idea?
My attic is open now, but not for long. I can get under the windows by removing the aprons.

I had a house with vermiculite filled block walls..still cold. Unless that mass is warmed up or isolated from you with a real thermal barrier..you will have cold walls. fact of life.
Boatwright -
The only way you'll solve the cold wall problem is as Sphere mentioned - isolate the masonry from the interior. This would be a major project but - take the lath and plaster off the exterior walls, furr with 2" metal studs and insulate with rigid insulation followed by new wall finish. This would fix the problem but, as I said, would be a major *major* overhaul.
Considering your heating costs and creature comfort, it might or might not be economical.
