Smoke and gas tight chimneys of good quality are important because of the increased protection of the safety of life and property. At the same time, properly designed products, which are, also importantly, manufactured with modern technology and from excellent raw materials, represent more economical energy use and a more environmentally sound solution.

The significance of advanced chimneys is supported by the fact that the hazard of chimney corrosion is reduced and properly dimensioned chimneys have lower air pollutant emission rates. When gas energy is used, the actual emission standards for sulphur dioxide, carbon monoxide and nitrogen oxides may be kept below the admissible standards, and taking into account environmental protection considerations, this warrants the widespread use of such advanced chimneys.
