EuroWindoor is pleased to contribute to the public consultation on the draft delegated regulation on resistance to fire performance classes. While EuroWindoor supports the initiative to set out resistance to fire performance classes under Regulation (EU) 2024/3110, to ensure harmonised declaration of this essential characteristic and maintain regulatory continuity with Regulation (EU) No 305/2011, it has noted an issue with class EI-M and its applicability to fixed windows.
In the last revision of the delegated regulation for defining classes related to resistance to fire performance of construction products a yearlong gap related to fixed windows was closed by adding these to Table 4.1 which originally was for partitions. However, not all of the classes existing for partitions are relevant to windows. Windows, neither openable nor fixed will be intended to withstand impacts arising from the failure of other components or objects exposed to fire and therefore class EI-M will not be relevant for windows.
