Double Ply Smooth Wall Round Chimney Liner Kits. Double ply smooth chimney liners have twenty percent more draft than single ply liners because single ply liners are not smooth (air moves faster of smooth surfaces because there is less resistance. The double ply smooth wall chimney liner is less likely to have creosote problems not just because the better flow of air going up the chimney, but because the creosote can slide back down the smooth wall and into the fire and burn off. Both double ply liners and single ply liners are flexible.
All of our chimney liners are made of 316L stainess steel and are made in the USA!
