The object of research is the fire resistance of an element of a translucent covering of an atrium with a frame-podium made of glass composite filled with foam glass. Method. The testing method to determine fire resistance limits was based on standard methodology. The following were recorded during the tests: temperature and pressure in the furnace, behavior, and sample deflection. Results. The fire resistance limit of a glass-composite podium frame has been determined. A graph of the dependence of the deformation (deflection) of the element on the temperature and time of exposure to flame was obtained. No relationship between pressure changes in the furnace and the behavior of the sample was revealed.
