Burglary resistance of thermal insulating clay unit masonry (RC 3) / Einbruchwiderstand von wärmedämmendem Ziegelmauerwerk (RC 3)

In 2017 the Austrian Clay Masonry Industry carried out a test of burglary resistance according to ÖNORM EN 1627 for the first time. A window was fixed in a highly insulated clay masonry wall (with declared compressive strength of the clay units 7.5 N/mm2). Resistance class RC 3 was verified for the window, the fixing to the wall and the wall itself.
