3'' Double Wall Lifetime Chimney Liner Kits

Lining your chimney with a Lifetime double wall chimney lining system will provide a 20% greater draft than using corrugated, or single wall, liner. Lifetime double wall liners are constructed with 316L stainless steel and feature a continuous seam for unbreakable strength. Another benefit is the ease of cleaning a smooth wall chimney liner. The smooth inner surface will be more resistant to dangerous creosote build up and is easier to clean. These chimney liners are UL listed to 1777 zero clearance standard and are fully covered with a lifetime warranty, even if you install them yourself.
