Chimney systems
Since 2006, CJ Blok® has been supplying the Polish construction market with chimney systems, consisting of expanded clay concrete hollow blocks, combustion product discharge liners and additional accessories. The technical development of chimney systems results from the growing expectations of customers in terms of rational energy consumption and environmental protection. The need to adapt chimney products to the requirements of potential customers and the applicable harmonised EU standards, has contributed to the creation of new ecological and energy-saving solutions, which are integrated with the applied boiler-chimney combination, e.g. overpressure operation and water vapour condensation operation.
The complete CJ Blok® chimney system is assembled using compatible chimney parts, specified and supplied by CJ Blok®, for which an average warranty of 30 years is provided.
