ABSTRACT

External constructions of buildings provide their protection of external influences. These constructions ought to create an optimal comfort of interior environment in winter as well as in summer. It has been shown in practice that the largest number of breakdown is in external constructions. The external constructions of walls, roofs and floors too, present a big area of problems in design of new and reconstructed buildings respectively. Heat losses of buildings trough external constructions – roof, external wall, floor on the ground are not negligible. It is therefore important to pay more attention to these constructions.
The building, which is directly on the ground is in direct interaction with the subsoil and its thermal state. An amount of heat primarily destined for creation of thermal comfort in the interior escapes from foundational construction and floor on the ground to the cooler sub grade. The outgoing heat represents heat losses, which unfavorably affect the overall energetic effectiveness of the building. The heat losses represent approximately 15 to 20 % of the overall heat losses of the building. This number is clear antecedent of need of isolation and minimize of heat flow from the building to the sub grade.
