I have a masonry chimney with a terracotta liner which has had a stainless liner installed inside the terra cotta. I need to insulate between the old terracotta liner and the new stainless liner. I have been looking at loose vermicuite and a product called thermix which is mixed with water and poured down the chimney. My question is which one is better? I am kinda leaning toward the thermix because I have used vermiculite in the past but with mixed results. I was just wondering what everyone's opinion is and if their are any other products out there that I haven't heard about that I may be able to use.
