Double Wall Pipe Inside the House

I am going to install a Jotul Oslo in a room with a cathedral ceiling. The pipe will run straight up vertically from the stove.
The length of pipe inside the house will be 11 or 12 feet.

I have been told that it is recommended that I use double wall pipe inside the house. Would 12 feet of single wall pipe work ok inside the house, or is it mandatory that I use the double wall?
I am not familiar with the double wall pipe for inside the house. Is there insulation between the 2 walls of the pipe, or what?

So I need a double wall pipe, but not pipe with insulation in it. Can you give me a link to this type of pipe? I just looked up some double wall black pipe, I don't know if it had insulation in it, or not, but it cost $35/ foot! Expensive, but if that is what I have to buy I will buy it.

I guess this is it. Black double wall pipe. It does not have insulation, only an air space between the two pipes. Inner pipe stainless steel. Looks like a high quality product.
Three feet for fifty bucks.

I am down in Dixie and there are no Menards down here but I am sure I can find it somewhere.

Well, you want to dance to the music, you got to pay the piper. I want a proper install. Plus, I am running the pipe up through a cathedral ceiling, and have to run the pipe past some giant 4x8 exposed rafters, so the 6 inch clearance with double wall pipe will make that easier.
I have had 7 wood stoves, and have been burning for 35 years but have never used double wall pipe inside the house. For example, my current stove is an Irish Waterford, and there is only 4 feet of pipe inside the house, so the idea of double wall with this install is a moot point. I did have a 1988 VC Resolute in a log house I built down in Georgia, had 10 feet of single wall inside the house and that stove worked great. But, that was a pre-EPA stove.
A different century, and a different stove.

I will get the double wall pipe for my new Jotul, who knows, I may mail order it from Menards.
I went up to visit my buddy in South Dakota several years ago, we built a fence in his back yard, any time we needed 2x4s or decking screws, it was "Go to Menards."
I had never heard of 'em.
We have no Menards down here in Dixie.

Look here! Here is the same Selkirk pipe, down here in Dixie at Lowes, and it costs 20 bucks more!

Y'all Yankees get the good deal and they stick it to us Rebels. Go figure. I might just mail order from Menards.
