Double wall stove pipe has superior insulation with 1/4" airspace between the inner and outer pipe walls. This allows hotter flue gas temperatures improving draft meaning:
Less chance of moisture or soot buildup within the vent Less "smoking" of the stove at startup Enhanced woodstove efficiency Less creosote build up More Expensive Pipe Not as light or easy to install
