You only need one or the other - ceramic board or ceramic blanket.  The board is more durable, but not flexible.  In either case you would want to coat the interior of the forge with something like satanite or kastolite to protect it from mechanical damage and/or flux from forge welding.  Both the blanket and the board are highly insulating.  I've had a piece of one inch thick fiber board glowing hot on one side and able to hold my hand on the other side without being burned.  It wasn't comfortable, but it wasn't damaging. For a box shaped forge I'd probably lean towards the board.  For any forge shape with curves my choice would be rigidized blanket.

thank buzz for answering my question

I AINT stupid but i ask u what you mean by clay

If it's a solid fuel forge you want NO insulating refractory. A few inches of compacted clayey soil will make the fire pot and table  to hold and shape fire and coal/charcoal. No insulation necessary, the clay liner is to distribute heat evenly not insulate. Spot heating sheet metal or cast iron can warp the sheet or crack the cast.

yeah but i dont get what u mean clayey soil and it be with propane  

My question is then If i was to use old bbq grill for a forge do i need to like it  with kaowool fiber  then use kaowool board or  will kaowool fiber work just alone
