clay flue liner sleeves, specifically designed for use in masonry chimneys or as multi-duct liner sleeves. Here is what they are typically used for: Chimney/Flue Connections: They are often used to bridge, sleeve, or line sections where a stove pipe enters a masonry chimney or where two flue sections meet, ensuring a fireproof and smoke-tight seal. Underfloor Ventilation or Ducts: Because of their rectangular, hollow shape, they are also sometimes used in older building practices to create air ducts through walls or under floors. Soot Doors / Access Sleeves: In some regional building practices, they act as the structural insert framing a soot door or cleanout access point.
A cavity liner is ideal for individuals who frequently consume sticky or acidic foods, as it can help reduce the amount of acids and sugars that come into contact with teeth, thereby decreasing the risk of cavities.
