• Polish
• English

The subject of the article is the interpretation of binding standards in the scope of minimum sound insulation of division walls. The article starts with a reference to the latest standards of noise protection of buildings in Poland and discusses them against the background of standards that were in force before their introduction. Afterwards, there is a description of the rules for determining the minimum insulation of external walls according to PN-B-0251-3:1999 and PN-B-02151-3:2015-10 standards. Finally, the advantages and disadvantages of determining the resultant insulation performance of an external wali are characterized and the differences in determining it using both standards are formulated.
