Thermal performance of glass pane under fire was studied in this paper. Heat transfer to glass and associated fracture were reviewed first. Glass temperature profiles on the glass pane were then summarized into three stages based on heat transfer: The first stage is on rapid heating up, the second stage is on steady heating up and the third stage is on losing heat to a certain value. Partial differential equations were set up on predicting the glass temperature at each stage with appropriate boundary conditions. By proposing different glass temperature variations for those three stages, three sets of partial differential equations were set up and solved. These three equations were then applied to study the heat up of glass with experimental data reported in the literature. The derived solution agrees reasonably well with experiment.
