Chimney lining

We recommend single-wall stainless steel pipes or exhaust systems made of polypropylene (PP) for refurbishment of existing, bricked chimneys, which thanks to their modular construction can be quickly and easily fed into the chimney. Depending on the fuel used and the operating mode of the fireplace or stove, various designs are available.

Double wall stainless steel chimney

In this chimney, which is usually installed on the outside wall of buildings, an insulating layer made of insulating wool between the inner stainless steel exhaust pipe and the outer jacket made of stainless steel ensures a constant temperature in the exhaust pipe and thus a proper functioning exhaust draft.

LAS Chimney

More and more modern heat generators and condensing units no longer draw the required combustion air out of the installation area, but instead work independent of the room air. The supply air is supplied via concentric LAS exhaust systems via the annular gap between exhaust pipe and stainless steel outer jacket.

Overview concentric LAS systems


The classic furnace pipe (or smoke pipe) is available in a wide range of lengths, colours and angles. We offer special designs for pellet furnaces and the insulated furnace pipe which helps reduce the distance to combustible components.
