Fire Behaviors of The Geomaterial-Based Composite Plaster Coated Building Thermal Isolation Plates
Thermal insulation in buildings has been a problem for mankind throughout history. New materials have always been used in this context, and every new material has negative aspects such as environmental, economic and engineering. Although the building exterior insulation materials produced in recent years have made significant progress in terms of thermal comfort, but those with superior properties in resistance to fire are very limited. In this study, considering the environmental sensitivity, the plasters produced from the sands of arenitized granite, micaschist, pumice and expanded perlite rocks and their combinations were applied on expanded polystyrene (EPS), extruded polystyrene (XPS) foams and mineral wool for investigating the fire behaviors of each material. As a result of fire tests, it was observed that the most positive values were gained from micaschist based external isolation board, whereas the board obtained from arenitized granite gave the most negative values. With the combination of natural and environmentally friendly materials such as micaschist, perlite and pumice, on a fire resistant insulation material such as mineral wool, a highly fire resistant, environmentally sensitive and economical insulation material can be produced.
