It uses a single wall 0.006" thickness that makes it stronger than other light liners. DuraFlex SS is the most economical liner for a straight chimney. This item gives you 20 feet of 4" liner. It should be used with the DuraFlex Zero Clearance Insulation Sleeve so that the UL 1777 standard for masonry chimneys and wood burning appliances is met.
