Any  supplier of concrete blocks should be able to get (or have on hand) 
large  (6 cu ft) bags of perlite which is used as insulation in the void 
spaces  of the concrete blocks.  Perlite works well as an insulation even  
when incorporated into a matrix.



All:
    Wear a P95 or better dust mask  from the time you open the bag until it 
is completely empty and in the trash.  You only have one set of lungs.
