Resistance of ETICS with Fire Barriers to Cyclic Hygrothermal Impact [PDF]
Sustainability, 2021 The article presents the results of a set of hygrothermal experiments of an external wall insulated with an ETICS. As an add-on to previous studies, thermal insulation in the form of polystyrene with an additional horizontal strip of mineral wool was used. Laboratory tests were carried out in accordance with ETAG 004. The ETICS test rig was composed of
