To mortar or not to mortar?
 
I am sure this is a silly question, but I don't know if I should mortar the soldier course bricks to the insulation layer or not? Is it better to let them have the ablitiy to expand and move accross the insulation layer?:confused:

Are the soldier bricks not sitting on the hearth layer ?

I have a 4 inch slab and on top of that I have fifty, 65cm insulation bricks surrounded by concrete. The soldier bricks sit on the insulation bricks and the fire tile floor sits in the centre of the soldiers. The soldiers are mortared to each other but should they be mortared to the insulation bricks?

IMO and it seems the opinion of a good many others...the soldier course or bottom course does not get mortared down...I think egalecki also used strips of paper under the joints between the soldiers so as not to have anything stick

That good to know,Thanks. Could I use aluminium foil under the soldiers to stop them sticking?

You could use foil, but the paper will burn away when you fire it up, so I'd use that. It was only newspaper strips I used.

That should work. Many have used the aluminum foil between the dome bricks and the insulating layer.

You guys are invaluable to new builders! I am cutting my floor tiles today so I will post some pics when I'm done.

My vote is for paper...portland cement and aluminum foil don't play very well together...I don't know if there is a funny byproduct
