Product List
DuraPlus
DuraPlus is designed to stay cool on the outside, to
provide a hot draft on the inside, to boost stove eciency,
and to provide for a re-safe design that protects both
the chimney and the building. This triple-wall chimney
features two insulating layers (ceramic blanket, plus air
space). The ceramic blanket insulation is held securely
in position, eliminating hot spots common with loose-
ll type insulations. In the event of a creosote re, the
compressible blanket insulation permits the chimney liner
to expand outwardly in a radial direction.
Designed for normal, continuous operation at 1000° F ue
gas temperatures, DuraPlus is subjected to rigorous and
stringent HT requirements of the UL standard, including
one hour at 1400° F, plus three ten minute chimney re
tests at 2100° F.
