The edge-construction of a glazing has an impact on the g-value of the glazing, measured by calorimetric devices. If no insulation is applied on the glazing edges (inside and outside) during measurements, heat will be transferred by conduction through the glass panes and through the spacer. The amount of energy transferred and the direction of the energy flow depends on the construction of the glazing (types of glass, coatings and spacer) and on the interieur and exterieur temperatures during the measurements. This paper gives an evaluation of the amount of energy transferred through the spacer in two different glazings in order to establish the maximum error that will result if no insulation is applied on the edge of glazing during measurements.
