Abstract

The aim of the article is to present the issues related to the use of climate panels as insulating materials used inside buildings. The study involved four materials, the two of them is a lightweight cellular concrete, the other two were produced on the basis of lime silicate. The main aim of the laboratory tests was to determine the coefficient of thermal conductivity λ depending on the changing temperature and humidity. Based on research the sorption materials curves were determined. The study allows you to specify the amount of moisture that can be accepted by the material in specific temperature and humidity conditions. In addition, the examined coefficients of thermal conductivity compared with the values declared by suppliers to assess compliance with the data contained in the data sheet.
