[en] Many modern public buildings such as airports or offices use fire-resistant glass which consists of layers of glass with transparent gel between them. In fire conditions, due to high temperature, the gel starts swelling creating an opaque, porous foam which blocks the heat transfer to other compartments.
The aim of the research conducted at the University of Liege is to create a numerical model for fire-resistant glass’ behavior in high temperatures, reaching up to 1000°C. It includes a numerical and experimental part in order to define the properties of intumescent layer as well as to validate the model through fire test.
The first results of the thermal simulation based on the one-dimensional heat flow through glazing did not show a good fitting with the results of two fire tests which were conducted in the purpose of the model validation. However, after some modifications of methodology, the model improved and showed better compatibility with experimental results. In the next steps different additional factors still need to be further analyzed.
