Abstract:
Abstract In the construction sector there is an increase in the use of natural insulation materials. The application of such products is limited due to the lack of sufficient information, documentation and experience. The physical/thermal properties of natural insulation materials can be improved by a multi-layered structure. In this case, the connection of the individual layers has an important role. Insulation materials are reducing the transfer of heat and sound and a key characteristic of such materials is the thermal conductivity. Wood-based materials have a low thermal conductivity and a positive insulation effect. The most important factors are the apparent density, porosity, moisture content and temperature. Wood and wood-based materials have, besides the good thermal insulation, a high heat storage capacity. The heat storage capacity of building materials, which are in direct contact with the indoor environment, has an impact on the thermal performance of the indoor environment. In this work, the thermal conductivity of cement-bonded chip boards was measured at three different temperatures and moisture contents. In this work three different chip boards combinations: single boards, double-bonded boards and board covered with clay were investigated. Based on these data the contribution of the materials to the thermal performance was assessed It can be seen that the thermal conductivity strongly depends on the moisture content, but also on the material density. Furthermore, the bond layer and clay influence the results significantly. The results show, that the single boards is best alternative to avoid an overheating in summer.
