This item gives you 20' of the DuraFlex SS chimney liner in a 5" diameter. The lightweight 0.006" thickness makes it stronger than many other light liners. It is the most economical liner for straight chimneys. The DuraFlex SS system provides efficient venting of heating appliances while it protects the masonry chimney from the damaging chemicals that are present in the flue products. It should be used with the DuraFlex Zero Clearance Insulation Sleeve in order to match the UL 1777 standard for masonry chimneys and wood burning appliances.
