 Rezime:
 In accordance with current energetic requirements, building construction joints developed significantly in the past few years due to new construction materials and building elements, due to the need for increased thermal insulations and the development of new building technology solutions. Window constructions also developed significantly, however, it is observable that mostly thermal aspects were considered, e.g. reducing thermal bridging around the joints. This paper presents comparative analysis of steady-state multidimensional conjugated heat- and moisture transport numerical FEM simulations of insulated wall and window sill, -lintel and horizontal sections. Two different type of wall insulations were also tested, and the effects of the joints’ thermal and moisture bridges were evaluated. The results shows how different, well insulated designs of window joints behave differently in the thermal and moisture aspect of view, when expanded polystyrene or mineral wool insulation come around the joints.
