Heat radiation from external wall of Dome??

Re: Heat radiation from external wall of Dome??

You will certainly not burn your neighbor's house down but you may, upon oven startup, send some smoke his way. You may want to consider the direction the wind blows across your yard.
Another item of note is that sandstome is extremely porous, and will soak up rain and any other moisture you can expose it to. I'm not sure its a real popular oven enclosure material. Maybe you could seal it?

You don't want to clad your finished oven with any material in direct contact with your dome. Adequate insulation is a must regardless if you render it igloo-style with stucco or bricks, or do the concreteboard and stone/bricks/tile etc.

A properly insulated oven does not heat up on the outside once cured. Mine will get warmer from the sun on one side than from heat form the oven.

If you plan on loading the dome, make sure the bottom course (soldier course) is belted to resist spreading.

This can be achieved by using vemicrete for insulation and then a 2 inch or so band of reinforced concrete 6 to 8 inches high around this. The reinforcing for this band could be reinforcing wire rather than rebar. The wire should completely circle the oven. You may have to "dive" it under (or over) where the door is to be.

Hi Folks

Firstly great web site and forum!

I am in the initial stages of planning a dome oven.

I have sourced good refractory bricks and mortar.

At the moment I am setting out possible locations for the oven. I want to place the oven as close to my boundary as possible, but local council restricts the distance to 450mm from the boundary. The neighbouring property is an additional 900mm from the boundary which equates to 1350mm or 1.35 metres from the back of the oven to the neighbours wall (rendered brick).

I am wondering is this sufficient? I don?t want to burn next door down! I will of course be utilising appropriate materials, insulating bricks below the oven, refractory bricks for the interior, insulation blankets and am currently looking at then covering the oven in sandstone.

That would be my second question, does the internal oven have the ability to support and additional layer of bricks or stone work?

Thanks for your time!
