Last year I purchased my SS flex liner from Woodland Direct and installed it myself. I bought all the components from them and was happy with what I got. This year I'm putting up 9-12' of rigid pipe through my ceiling for wood stove number two, and I'm looking at using DuraVent DuraPlus triple-wall components. I see Home Depot does the 36" sections for cheaper than anyone else. Does anyone know if it is the same quality as what is sold for twice as much somewhere else? The model numbers seem to line up. Unfortunately, Home Depot doesn't sell all the components I need. Does anyone have any recommendations for the best place to shop online when you're just piecing it together yourself? Thanks.
