Describes the use of infrared IR) thermography to compare the glass surface temperatures of insulating glass (IG) units made of two types of spacer bar (metal and silicone foam) and different gap widths. Compares the results with data from another research laboratory using a different IR scanner and also with data from finite-element computer modelling. All the tests and simulations were performed on identical IG units. States tests performed on seven IG units indicated that thermography could be used to assess the edge-of-glass temperature of IG units for the prediction of condensation resistance of the units. The vertical temperature profiles of all the tested units showed considerable reduction of temperature at the bottom section of the IG unit.
