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 was wasted wrapping insulation around the 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 Canada.
