Re: just about to drop a clanger

40 quid for a piece of board...!!

Put thermalite blocks underneath the oven, it has the same effect and much cheaper.

Thermolite will take the oven hight wrong as the base is now in and at the required height....i guess im gonna have to swallow the 40 quid to ensure I have the right insulation...grrrr

I tried to DL the pdf for building the pompey oven and it wont let me as I don't have a US postcode......

now DL the file and says corrupted and wont open..... I guess I should go to the pub.....

Re: just about to drop a clanger

Thanks guys, had some thoughts, masses of reading although many people seem to have different oppinions so after much looking I found this for insulation under the floor ...

Vermiculite Fire Board - Fire-proof Insulation


The same company sell lots of other bits including insulation.....your thoughts would be appreciated..... god this gets confusing the more you read.

Sand is a heat soak and very poor insulator. It would be advisable to study the Forno Bravo Oven plans: (eBooks & CD ROMs :: Forno Bravo Store) and
read through the Pompeii Oven Construction threads on this site, paying attention to the insulation materials the bulk of the builders use. The pics everyone shares are invaluable.

Hi

There are a few UK builders on here - but there should be more.

I think you are about to "drop a clanger". Your base and dome insulation will be very inefficient. For a minimum you need to mix in vermiculite to the cement, then your dome and floor will hold heat much longer.

Hi All,

Yup i'm new to the forum, started to build an oven, I am to the point of;

Completed foundations, layers of building blocks to the required level for casting the base.

Now, here is when I joined the forum, read loads of different oppinions on a mix for the base, insulation for the base, can the oven be built straight on the base...etc etc etc.

I was going to do a simple sand, portland mix with lime, then a dome firebrick followed by 3 inch insulation of the same mix for insulation.......am I about to drop a monumental clanger is the question?

A great forum with lots of debate....oh and I do burn pizzas in a conventional oven....lol glad I joined and thanks for any help on the above..
