Michael Judd says that if permies.com brings in $5000 to his kickstarter, then permies.com can decorate an entire page in his new book! I'm not sure what we would put there just yet, but the opportunities for comedy are endless!
Yes ! We say that ' warm air rises against gravity' and 'cold air condenses and sinks' these are laymen's descriptions of what we see happening every day !
I don't know of any way using Science / Physics to say it any better so ,while i would change' insulating after ' to 'insulating before/when', - warmer air will always increase 'draft '!

I agree with Allen.
The greater the difference in temperature, between the air inside the pipe and the air outside the pipe, the greater its need to 'escape' the pipe. An insulated pipe will keep the exhaust gasses warmer, therefore they should escape quicker, ergo, more draft.
