EXPERIMENTAL RESEARCH OF ENCLOSING CONSTRUCTIONS FIRE RESISTANCE WITH PLASTERBOARD PANELS

Abstract

The article deals with the application of energy efficient materials in construction of buildings and structures for various purposes. Enclosing constructions prototypes made of profiled metal with a filler of foamed polystyrene with a thickness of 100 mm and two additional layers of plasterboard with a thickness of 12.5 mm are considered. Experimental researches of fire resistance of prototypes in the oven for thermal testing of small fragments of buildings and individual units of their joints were carried out. Methodology for fire tests was described. Temperature distribution in prototypes by their thickness is presented. The boundaries of fire resistance were determined and conditions of application prototypes in buildings were justified.
