complexity to the installation.
Screws needed requiring more installation time. No end ring
coverage exposing insulation to outside environment. 4 spot
welded connecting tabs creating weak connection between
inner and outer wall.
Screws needed requiring more installation time. Twist lock connection with exposed insulation.

430 Stainless Steel Inner Wall
Corrosion resistant stainless steel with the smallest amount of
expansion when exposed to heat. Prevents hot spots from appearing
which could cause a re.
304 stainless steel inner. Expands almost twice as much
as 430 stainless steel. Could cause hot spots and gaps in
insulation.
304 stainless steel inner. Expands twice as much as 430 stainless
steel. Could cause hot spots and gaps in insulation.
Use either 304 or 316 inner wall with 430 SS outer wall.
300 series SS expands twice as much as 400 with less
memory causing stress on joints due to inconsistent
expansion.
Uses 430 Stainless Steel
304 Stainless steel inner wall expands twice as much as
430 which could cause hot spots.
.020" thick Stainless Steel Inner Wall
Thickest inner wall construction in the industry providing the best
protection from creosote res.
.016" Inner wall thickness .016" inner wall thickness. .016 inner wall thickness. .015" Inner Wall thickness .016" Inner Wall thickness
Option for either Stainless Steel or Galvalume Outer Wall
Customer has the option to use a less expensive galvalume outer for
interior chase installations to keep costs down.
Oers both Stainless Steel outer and Galvanized Steel outer.
Galvanized more likely to rust than galvalume.
Stainless Steel only option for outer casing adding cost. 430 SS outer wall is the only choice.
Oers both Stainless Steel outer and Galvanized Steel outer.
Galvanized more likely to rust than galvalume.
Only 304 Stainless Steel outer available. Makes inside
chase installations more expensive.
Light Weight Construction
The light weight Thermo Tech insulation makes pipe sections lighter
(5lbs per ft for 6" diameter) to allow the manufacture of 5' lengths. Thus
allowing the installer to make fewer trips up the ladder for a quick and
easy installation.
Packed chimney is a heavier product. 6lbs per foot for 6"
diameter.
4.2 lbs per foot for 6" diameter. No details supplied on insulation.
Chimney pipe is one inch wider in material making it more
heavy and awkward to handle.
Packed chimney is heavier product. 6lbs per foot for 6"
diameter.
1" Double Wall Insulated Pipe
Has the smallest outside diameter available to allow easy placement
between studs. i.e. 8" O.D. on 6" diameter pipe. Saves from having to
reframe around the chimney.
1" double wall insulated pipe construction. 1" double wall insulated pipe construction with no end caps.
1 1/4" double wall insulated pipe construction with no
end caps. O.D. on 6" pipe is 8.5" tighter t to framing.
1.5" double wall insulated pipe construction with opened end
caps exposing insulation to outside environment. They taut
1.5" clearance over others 2" clearance but with the added wall
thickness this chimney requires the same amount of spacing for
clearances as all others.
1" Double wall insulated chimney pipe.
1" Thermal Tech Blanket Insulation
Insures complete insulation coverage between inner and outer walls,
preventing any hot spots from appearing due to expansion of the
metal walls during operation. Hot spots could cause a re.
