Re: some questions about staying warm -- floor insulation and heating
You really only use the double walled insulated pipe anywhere near combustibles, such as when you go through a wall/roof or where the pipe is close to materials. That pipe is probably your #1 defense against finding yourself waking up in the middle of a round inferno. Cheap out on the stove, the hearth or even the wood long before you do so on the stove pipe.
Indoors, you can have single walled pipe until you get close to combustibles. Outdoors, that pipe will have a limited life and will rust. The insulated pipe however will probably outlive you.
Memory foam? You mean like the kind that goes on beds? I guess it might work but I would be a little concerned with rodents making homes with it.
