An update on insulation for those in Ireland. Like eirebuild, I couldn't find Ceramic Fibre board and at times when I thought I had located something useful I was unable to get information on compressive strength.
I have opted to purchase CaSi board from Potterypro, works out at about £27 delivered per 610x500x50mm sheet. Just wondering do I need some vcrete between concrete hearth and CaSi board for extra insulation.
As for firebrick, I sourced this from Ray Graham in Newtownards. The brick they stock comes from Dineen in Athy.
