Re: Floor Insulation

Question...are you finding the floor too hot?

Initially, when I relied on only dome-reflected flames to heat the floor I could only get 400-500F in the center of the floor, making for some pretty doughy pizzas. Now, charging the floor with coals for several minutes, I have been able to get both dome and floor 800F.

The last few sessions this has worked well for my neopolitan pies using Caputo 00 and sourdough starter.

is the floor soap stone?

Re: Floor Insulation

I used both vermiculite (bottom 3.5") and 2" calcium silicate board on top. After a number of 800-900F pizza sessions the bottom of the support slab remains at ambient temp.

Re: Floor Insulation

When you look at the vermiculite slab you think there is no way that it will support the dome but it does and is surprisingly strong.

Re: Floor Insulation

just a recommendation: use some FB Board or equivalent for the actual base under the floor bricks. I think the gain in efficiency and heat retention is easily justified.

Re: Floor Insulation

Tarter3,
Dave is right about that. I just want to elaborate on vcrete strengths. A 5 to 1 (vermiculite to portland cement) is what is recomended for the floor. Vcrete over the dome is usually about 10 to 1. You probably have picked that up already. I just wanted to be sure .

G'day
Yes there is no problem with the insulation layer supporting the oven whether its pearlite cement or ceramic board. I know you can dint the surface of both with a fingernail but the weight is spread out so its supported. All the ovens here are built directly on the insulation

Hi all just have a quick question, I have been searching the forum about floor insulation and can't find the answer. Can I put the soldier bricks directly on top of vermiculite concrete,I am concerned that it will not support the weight of the oven
