Hi,

Just done this myself with vermiculite/micafil.

See http://www.solidfuel.co.uk/pdfs/open..._fireplace.pdf for

Hello all,

I have a victorian cast iron fireplace that I need to backfill, but
can't for the life of me find any information on how to do this. Does
anyone know of any websites or books that could point me in the right
direction?

Thanks in advance...
