[QUOTE="HiredHand, post: 1910403, member: 2469"] I think most fireproofing is fire rated sheet-rock. Maybe this link will help, [url]http://www.6mmbr.com/gunsafes.html#fireproof[/url] Many safe manufacturers use common sheet-rock as fire-lining. This is not the best solution, because when heated, standard sheet-rock will crumble. There is a sheet-rock that has fiberglass embedded in it.
