Hello from Minnesota
Hello everyone! I've been reading about wood-fired ovens for a while and am leaning towards a modular one, to save time. Does anyone else who lives in a climate like mine have an opinion on Casa versus Premio? Since the Premio has more insulation it seems like it could be a better choice. We had a bit of snow here even yesterday (end of April).

Also - We're thinking of a simple floating slab, since digging a full foundation would require a LOT of digging up here. Has anyone in a similar climate used a floating slab, and if so, how level has it stayed?

Thanks so much, everyone, for your guidance and wisdom!

Welcome :)
I've seen several posts here saying a floating slab works in a cold, cold climate.

Call Fornobravo and ask for Hiedi, (TEL: 800 407-5119, ext 14 I think), and ask your questions, she will get you the info you need. :)

You don't need a foundation per se for the oven. The floating slab would easily be sufficient. What part of MN? West metro for me.

Hi Tman -- we're in the Linden Hills neighborhood of SW Mpls, near Lake Harriet. I'm so happy to see that ovens work up here - even if we have to clear a path to them for 5 months of the year. ;)

Hi EliseR,

A floating slab sounds simple enough. Do you know what a floating slab is and the proper way to build it? I didn't until I looked it up and found this. What is a floating slab and why do I need engineered stamped drawings? Floating has the answers. You can also Google "floating slab" to view various descriptions. You may not need stamped drawings but the general information is good and easy to understand on this site.

It is more than just concrete poured into a 2 x 4 frame staked to flat ground. Look through the site and click on FAQ and other areas to get some idea before you start.

Getting a good slab at grade (a floating slab is suitable if done properly) is essential to get your block stand and oven slab off to a good start.

1. Floating slab are to rest on undisturbed soil.
Grammar aside, That's not what I learned: Six inches of well drained crushed rock keeps the water that causes frost heave away from the slab. It's sub-frost-line footings that are poured on undisturbed soil.

Thanks, all! I appreciate all the advice.

Re: Hello from Minnesota
Here right across the border in western WI. I had a patio poured last year. I told the guy who did it that I wanted a bump-out in the back for an oven... so he dug down around the periphery about another 8 inches and laid rebar, giving about a foot-thick reinforced edge.

The whole patio floats on the ground, except for the edge which is over some gravel.

Two caveats - it's part of a larger 15' x 30' patio, and my "ground" is an ancient sandbar, almost like play sand once you get down a foot or so.
