COMPARATIVE ANALYSIS OF DIFFERENT GLASS TYPES DURING THE STANDARD FIRE TEST

The paper investigates the fire resistance of three types of glass samples exposed to standard fire conditions. The tested samples were: thermal insulation glass (4 + 16 + 4 mm), single glazing with 8 mm thickness, and single glazing with 6 mm thickness. All three samples were placed in the standard furnace and tested simultaneously. The objective of this testing is to evaluate the possibility of replacing single glazing with thermal insulation glass (double glazing: 4 + 16 + 4 mm) in applications where single glazing is currently planned. The aim of the testing was to determine when all three samples would lose their integrity, i.e., when the last piece of glass would break. Installing thermal insulation glass in places where single-glazed windows are installed has higher heat loss in winter, as well as better comfort inside the rooms in summer. Some buildings are equipped with single-pane windows, which are installed with the intention of allowing rapid breakage during a fire to facilitate the extraction of smoke and heat. The glazing type relevant in this case is one that will lose its integrity within 15 minutes of testing. The results indicate that it is feasible to install thermal insulation glass (4 + 16 + 4 mm double glazing) as a replacement for single-glazed windows
