Long-term Monitoring of Thermo-technical Properties of Lightweight Constructions of External Walls Being Exposed to the Real Conditions

The article describes the results of long-term measurements of thermo-technical characteristics of lightweight sandwich external walls suitable for using in passive wood-based buildings. Monitored were the samples of walls, which were built into the external wall of the climatic chamber of pavilion type during four years of their exploitation. Inside the chamber, the stationary climatic conditions were maintained throughout the whole year and from the exterior side, the samples were exposed to the real weather conditions. The results of selected monitored thermo-technical parameters are presented, such as: temperature, water content in insulation materials and coefficients of thermal conductivity of materials incorporated in the compositions of the walls.
