Hi all
Does anyone know if you can use a vermiculite board to construct the oven floor?
It would give a lovely flat finish but unsure if it would work. And if safe for the food to be in direct contact with.
Thanks for your help

Vermiculite is insulating so it doesn't hold the heat which is what you need for your hearth. Be great with firebricks on top though and will give you that nice flat surface. |

As above, vermiculite board will provide an excellent base for a fire brick floor, but is too friable to use as the floor itself. I used it under storage heater blocks and my oven works just fine.  |

ok, thanks for your help.
Am I right in thinking that you do not need fire bricks, that standard Clay bricks will be ok?
Also, can you just bed them on a sand layer, or will they need some cement?
thanks

You are right that you don't need firebricks, but I can't recall a build that used ordinary building bricks for the floor. I used storage heater blocks as they are wide, not too thick, have a smooth side, and we're very cheap ! I laid them direct on the vermiculite board without any sand or screed, you could do the same with bricks if they are all the same depth. If you did lay a brick floor then I'd suggest using the herringbone method to avoid ridges at right angles to the tip of your peel; wider bricks mean less ridges.
