SKDZ - heat resistand double walled chimneys

This chimney system is used to build selfstanding chimneys taking out fumes from wood burning stoves.


Double walled heat - resistant chimney system are used for building chimneys taking out fumes from wood burning stoves. Chimneys are made with the inner pipe made with 1.4828 (acc. to DIN17441) , outer pipe - 1.4301 (acc. to DIN17441), thermal insulation - ceramic fibre wool, thickness 50m. The chimney made from elements of this system is a self-standing construction, not needing usage of any additional ceramic materials.

  • to construct selfstanding chimneys extracting fumes from woodburnig appliances


  • high acid-resistance 
  • much lower resistance of fume flows in comparsion to traditional brick chimneys, because of small roughness of the surface
  • possibility of applying chimney with buildings with no traditional brick chimney
  • wide possibilities of system configuration
  • wide range of products, possibility of making non-standard products
