From the representation of the isotherms calculated in this way, the glass surface temperatures in the range of Edge bond determined. They are a measure of the quality of the thermal insulation. Higher temperatures in the edge area improve the k-value and thus the thermal insulation of the window and reduce that Appearance of condensation.
