In this paper, the results of Moisture Buffering Test (MBV) of the internal walls with a range of different internal and external layers, made from renewable, hygroscopic row materials were presented. All of the investigated wall assemblies, with varying moisture loads in the range (50 – 80%), showed “good” moisture buffering value in relation to the buffer class proposed by Rode [11]. The presented results confirmed that the moisture buffer potential of the assemblies is influenced by used materials especially theirs material composition and structure.
