The paper presents results of thermal conductivity measurement of composites based on gypsum with addition of microencapsulated phase change material (PCM). Samples of different concentration of PCM and in the temperature range typical to building indoor conditions were analyzed. The investigation has shown strong influence of both PCM content and temperature on thermal conductivity. Materials under investigation are used as a construction material in building application. Thanks to the contribution of PCM gypsum wallboards have substantially increased thermal capacity (thermal inertia). Properly incorporated in building envelope such materials can stabilize indoor temperature (thus improving thermal comfort) and, as they operate as thermal energy storage elements, reduce energy consumption of building.
