Interior thermal insulation materials on natural basis: Evaluation of heat losses reduction

Popis výsledku v původním jazyce

Thermal retrofitting of historical buildings represents the only way how to ensure their thermal protection according to current stringent thermal standards. In case of these buildings, interior thermal insulations should be mostly used since an application of exterior ones must not comply with preservationists’ requirements. Natural thermal insulations represent a material solution that is compatible with historical building materials. This paper therefore aims at energy balance investigation of three types of natural-based insulation, being placed on the interior side of sandstone masonry. The annual heat transported through the wall segment is calculated based on hourly values of heat and moisture fields in the wall. Comparing with a plain wall, the efficiency of particular insulations is expressed. The results showed that all the materials (flax-, hemp- and jute fibers) are very efficient from the point of view of heat losses reduction, as the decreased it by more than 80%. The most efficient material solution was represented by jute fibers which led to reduction of energy losses by up to ~85%. Anyway, all the insulating materials showed to be promising for applications as the interior thermal insulation systems for traditional or historical buildings.
