Point thermal bridges are usually overlooked, their influence on the building’s energy may be significant. For warehouses, production and wholesale halls, the usual perimeter construction is a lightweight construction with thermal insulation between two sheets. As a thermal insulation in a significant number of cases, PUR, resp. its PIR modification. Recently, however, systems using thermal insulation of mineral wool are preferred. These structures, however, have both point and linear thermal bridges. In this paper, we focus on differences in the heat transfer coefficient calculated more precisely by using the ideal 1D, 2D and 3D model fragments and their comparison with the values reported by some manufacturers / vendors. At the end of the paper, we are devoted to quantifying the economic difference between the "offered" state and the fact determined by a more accurate calculation.
