Superior Clay, Menards and The Home Depot carry clay chimney flue liners. Customers can purchase clay chimney flue liners on the Home Depot or Menards websites or use the dealer search tool on the Superior Clay Corporation website to find dealers in their areas.
Superior Clay carries vitrified clay flue liners from 4-by-8 inches to 24-by-24 inches in square and rectangular flue liners and from 3 to 36 diameters in round flue liners. A complete chart of available flue liner dimensions is available on the Superior Clay website.
Customers can order The Home Depot's 24-by-12-by-8-inch clay chimney flue lintel or Menard's 8-by-8-by-24-inch clay modular flue online, but must pick up their purchases from a store.
