FB Brand Insulation

[Lill Dave]

I'm building my second oven in Grapeview, wa. and will definetly be using your new products.
Also would it be possible to purchase your 12"x12" floor tiles , my last oven had the 9x4.5 x 2.5 refractory bricks wich work fine but have more seams.
Thanks in advance David

Nothing wrong with (old-school) How do you think we got here? New tec.'s great but the old boys weren't that bad.

I am building my oven on a slope, so the oven base is on the ground clay. I thought to lay the first layer of rebar concrete on a plastic DPM. Could I then put a layer of blue styrofoam, the sort used to lay underfloor heating pipes in poured concrete domestic flooring. This would give protection against rising damp as well as extra heat barrier. Next the silicate FB board. Try for 3" in the hope that no more than 100deg will ever penetrate to the styrofoam. Finally the refectory bricks.
Does anyone know if this could work?
My next problem for another thread is that the soild will then be stacked up from the slope behind the oven, so to prevent water penetrating where it leans against the oven dome.

We are able to purchase 12"x36"x2" boards, so you can buy only what you need, and won't waste material. The cost is $27.50 per board, which is less than SuperIsol -- and very close to the cost of vermiculite.

What happened to the price??? The store now says $70.00 per board!
That would mean I need to spend $210.00 for 3 boards??? Ouch Thats a third of my entire material list for Stand, Hearth and Dome.

Am I seeing this price correctly?

Thanks

If you look closely you'll see the boards now are double the size James mentions in the post you quote. The price is has gone up but not much considering the way the price of everything has gone up the last few years as the dollar has plummeted.

Ahhhh yes, you are right! I did not see that. 12"x36" vs. 24"x36"

Makes me feel much better. Thanks again!

I placed the fb board on my platform and trimmed to size with a jigsaw. worked great. Only problem is inconsistent thickness of FB board. See photo. I will level with fireclay and sand mix as recommended from previous post. Is this normal for the FB board?

[mfiore]

I had the same problems with the FB board. There was quite a bit of variation with thickness. I did the same as you suggested, put a layer of dry fireclay underneath to even it out.
