My UK build is out of the ground!

Re: My UK build is out of the ground!

Oh I also meant to comment on the vent arch!

The path from the oven to the chimney gets really hot. I measured 800 degrees at the top of the vent arch once. That's not a good temperature for regular bricks from what I have read (I am no brick expert). Lower down in the vent arch it is MUCH cooler. But honestly the vent arch doesn't use a lot of bricks and it doesn't seem worthwhile to me to use regular bricks there simply to save few dollars (or pounds in your case).

The outer arches you can make with regular bricks no problem. Check out the front of my oven.

Re: My UK build is out of the ground!

nice stand! I also have a brick base

some people level the surface under the CalSil, and others level on top of the CalSil before they lay the floor. I went with leveling underneath. I used liquid self-leveling compound on top of my concrete base (honestly I am not sure why you used vermicrete if you are going to use 4" of CalSil but you will certainly have extra-super-insulation!). The self-leveling compound made my floor perfectly level and after I laid the CalSil I could lay the floor bricks right on top with no further leveling required. Or as David S suggested you could use sand/fireclay under the CalSil.

Very nice looking brick work on that stand. Have you done brick work before?

Re: My UK build is out of the ground!

Just a couple of bits of advice I need:

If my calcium sil board does not sit flat on the vermiculite, what is the best way to even this out? My concrete is level and flat, just may have a small ridge or 2. I will try scraping them of first.

When the time comes, does the vent arch have to be built in fire brick?

you can use a 50/50 mix of sand and fireclay to even out the wobbly vermicrete. just wriggle the calsil board into it.
You do not have to make the entry from brick. It can be done in stainless or you can cast it using castable refractory. There may also be other materials that could be suitable.

Firstly, I would like to say thanks for such a great forum, it has been a wealth of information over the last few months as I have been planning my build.
I would also like to say thanks to all who have helped out already on offering advice, (im sure I will be needing more!)

I am building a 40'' oven with a brickwork base and rendered chamber. My entry arch will be brick, and haven't decided on what to do with the chimney yet!
So, I recently got my foundations in, and built my walls for my hearth/counter top. I have also poured my rebar concrete slab at 4'', and got the 3'' vermiculite slab down.

I have got my vermiculite down, just not got a photo yet.
This weekend I will get my cal silicate board down which is 4'', and start setting out. Will get the herringbone floor down and maybe start my dome!

Any criticism is always welcomed, as well is advice.
