Issue with Glazing Performance analyzing Internal Temperature

Hi, I am still a bit new to Honeybee, I am trying to test the difference single glazing has in comparison to double glazing on the temperature of an internal space. When I test it I am seeing minimal differences, was expecting a significant internal temp drop within the space when using double as opposed to single glazing. Maybe more so just looking for advice, would editing wall, floor and ceiling constructions have much of an impact in the accuracy of this and provide a more feasible result? Just a bit lost. Thanks
