Experimental and numerical investigations about the fire behavior of ETICS facades based on EPS

摘要

Due to recent fire events a controversial debate concerning facades fires particularly in multi-storey buildings of German buildings class 4 and 5 is originated. The fire protection measures and testing methods of external thermal insulation composite systems (ETICS) with polystyrene are being criticized. To objectify this discussion further studies are required, which allow to evaluate the performance of the facade systems during fire exposure. For a systematic scientific study of the effect of different fire scenarios experimental studies under the guidance of the Institute of Building Materials, Concrete Construction and Fire Protection (iBMB) of TU Braunschweig were carried out. An essential part of the experimental studies four major fire tests on a flat facade with ETICS performed with a polystyrene insulation that were commissioned by the European Institute for Fire Protection (EIFP) were tested at the Institute for Material Testing (MPA) Dresden, which is located in Freiberg.
