【 摘 要 】

Recommendations about elimination of the thermal insulation's defects are offered in this research. The recommendations are based on the thermal imaging inspection of residential buildings, which were built with aseismic demands. The designing construction solution of filler structures taking into account the increase of comfort in the room is presented. In the proposed work the typical designs structures of the site supporting floor slab on a brick wall (width 770 mm). Aseismic horizontal frame is abutting to the floor slab on the same level. The insulation layer of 140 mm width made with expanded polystyrene sites on the whole height of the wall. This layer is braked aseismic horizontal frame on the floor slab level. The aseismic horizontal frame is covered by the expanded polystyrene of 20 mm width. The thermal bridge in the direction of the facade is very typical for this designing construction solution. The thermal bridge is in the mid-height of the floor slab near the insulation layer. The purpose of the research is to find a solution which will minimize or elimination thermal bridge with using additional insulation layer sites in the different level. Repeatability of thermal imaging inspection of designing construction solution and theoretical calculations in the software package ElCut are confirmed. The presentation is illustrated with examples of temperature fields for the different residential buildings.
