Evening guys,
My first post on your very interesting forum. I'm currently planning the buggery out of my first project - Wood burning oven, bbq, and granite worktop all surrounded by lovely decking. I've planned it all on sketchup which i'll post up later.
I'll no doubt be posting loads of questions....
Cheers
Stevo

Hello, This is the plan - please correct anything you may think might not work, i'm only going on what i've read here and on other sites. Concrete reinforced foundations Concrete block base Concrete slab Heatproof cement base Firebrick cooking surface, walls and roof. Render the bricks with fireproof render (white) Render the concrete base white I'm not the neatest brickie which is why everything is getting rendered, my joints are never good enough to be on show. Let me know your thoughts...i've got to extract the digit as i've got a bbq organised for the 04/08!! Cheers Stevo Attachments:

Love the sketchup model and your method of application. One thing that's missing is the very important insulation.
Between your slab and hearth you need an insulation layer. Some members have just used ceramic fire-board, others have gone down the route of vermecrete (vermiculite, cement and water.) Myself I use thermolite blocks between concrete slab and fire-brick hearth......you must have some sort of insulation between hearth and slab, or the hearth will just act as a heat sink and draw the heat away from the hearth.
The same is used for the dome. On top of the bricks is usually laid a thermal blanket. On top of this is usually vermecrete (that's what I use).....2x100ltr bags of vermiculite dumped in an empty 1 ton jumbo bag. About 1 bucket of water is poured and mixed into the vermiculite the night before. The following day half a bag of cement can be added and mixed through. This is laid on the thermal blanket with a couple of layers of waterproof render on top of that. There are many variations of this, but a thermal/fire-stop layer under your hearth and on top of your dome will improve fire-up times and give the oven a massed temperature so as the oven will retain heat, is cheaper to run and Ummmm much better.
I don't want to confuse the issue, but these thermal layers are very important in getting the best out of your oven.

Terry, thats the kind of help/information i'm looking for.
It's the bits that you can't see or instantly recognise in people's construction photos.
I'll be digging the foundations over the long weekend so i'll start a wee thread on it.
Cheers so far.
