DuraLiner Chimney Liner
DuraLiner ensures safe and efficient venting of heating appliances while
protecting the masonry chimney from the damaging effects of flue gas. It is
the only factory-insulated product with zero/zero clearance for high-heat
wood-burning appliances.
No need to uncoil flex, insulate a majority of the pipe or protect the
insulation when installing. A smooth inner means less creosote buildup.
Installers reduce labor time by 50% or more with DuraLiner. No time wasted
wrapping insulation around liner for UL 1777 approval. No spacers are needed
to maintain clearance in tight offsets or dampers. Approved for use in both
the USA and in Canada.
