Caligo GmbH works in consultation with clients, planners and architects to design and layout its steel chimneys while taking into account circumstances on site. Naturally, we also see to it that the technical requirements as defined in DIN V 4133 and DIN EN 13084-7 are adhered to. The German code of construction regulations (Bauregel-Liste) specifies that the mandatory CE / U mark must be obtained for all smokestack systems. We distinguish between basic forms of smokestack systems.


These are: the freestanding double-walled chimney with flue gas inner lining, the multiple-flue freestanding chimney, and finally the adjoined, single-walled chimney with load-bearing flue gas channel. The systems are erected individually or arranged in rows or groups. The following contains a schematic description of the three different structures.
