The DuraVent DuraPlus 6" x 9" Chimney Pipe is a premium triple-wall chimney system engineered for safe, efficient venting of wood stoves, fireplaces, and solid-fuel heating appliances. Designed with advanced ceramic blanket insulation and an insulating air space, this insulated chimney pipe stays cool on the outside while maintaining a strong hot draft inside to improve stove efficiency. The secure insulation eliminates hot spots common in loose-fill systems and enhances overall chimney safety performance. In the event of a creosote fire, the compressible insulation allows controlled radial expansion of the chimney liner for added protection.
