The Breakage Behavior of Different Types of Glazing in a Fire
Different from concrete and steel, window glass or glass façade breaks very easily when subjected to a compartment fire. The new vent created by the glass fallout may cause fire spread out and fresh air entrance which can markedly change the enclosure fire dynamics. Nowadays, different types of glazing, such as clear, coated, ground and multi-pane glazing, are increasingly employed in newly constructed buildings. However, very little is known about their fire risk, especially the comprehensive comparison between them is yet to be investigated. In this paper, the fire resistance comparison of different types of glazing is conducted based on the author’s very recent and ongoing experimental results. Literature works of other researchers are also presented for comparison. Additionally, fire safety design and recommendation of glass in buildings are discussed in detail. This research is proposed to provide valuable references for the fire safety performance-based design of glass façades in high-rise buildings.
