System ociepleń z barierą ogniową – symulacje numeryczne rozkładu temperatury w obrębie ściany

The article presents the results of numerical calculations of external walls insulated with polystyrene with an additional fire barrier in the form of mineral wool. Two types of construction layer were established, made of monolithic reinforced concrete and autoclaved aerated concrete blocks. As a result of the calculations, temperature distributions in the cross-section of the wall were obtained, with their characteristic values in specific places. For the assumptions made, a slight temperature variation on the inner surface of the wall and high values of the temperature factor f_Rsi were demonstrated.
