DuraLiner
DuraLiner ensures safe and ecient venting of heating appliances,
while protecting the masonry chimney from the damaging eects
of ue gas. It is the only factory-insulated product with zero/zero
clearance for high heat wood-burning appliances. No need to
uncoil ex, 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 needed to maintain clearance in tight osets or
dampers. Approved for use in both the USA and in Canada.
