Double wall insulated chimneys & inox fittings

A double wall chimney consists of two stainless steel pipes, one inside the other, with insulation in between. Flue gases keep their temperature along the whole route, so the draught stays steady, less condensate forms and the outer surface stays much cooler.

It is the right choice for chimneys that rise along the outside of a building or pass through cold spaces. The size is given as two figures, inner and outer diameter; the inner one must match the appliance outlet. You will find straight lengths, 45° and 90° bends and tees by Art Kamin.
