Thermal response of low-E and float glass facades under various heating rates

Abstract

Glass curtain wall has been widely employed in buildings. These glazing may easily crack and even fallout when subjected to a fire, which would influence the structural integrity and is especially vital for the interactive-external tridimensional fire development. Low-E glazing is extensively used which may bring energy conservation with potential fire risk. Here, low-E and float glazing were heated by a radiant source under various heating rates. Numerical simulation concerning the heat transfer was conducted to explore and compare the heat transfer mechanisms.
