Without looking it up, my understanding is that it's little bits of Mica, about the size of rice coal. Very annoying when it falls out of the edge of the ceiling every so often (as it did after I tore out the dining room walls).bksaun wrote:Is vermiculite the same thing as mineral wool?

my dad put vermiculite/perlite in the attic when I was a little guy......he started with rock wool but my mom got itchy.....this was about 1974.......he bought up all the vermiculite/perlite that the local lumber yard had for that winter.....it is a pain in the arse when you open up a wall, but it is decent insulation.....when I had the walls in the house open I had to shovel the stuff into bags and fill the voids with toach foam and put it all back in the attic
