Special use windows
We have successfully finished testing PONZIO PE78N RC4 windows with regard to bullet resistance (in acc. with the EN 1523 standard). A structure glazed with IGUs with BR4 glass panes and secured from the attack side in the external cavity with aluminium flat bars fulfilled the requirements of class FB4 in acc. with EN 1522. Analogous windows with IGUs with BR6 glass panes and secured with steel flat bars have been classified FB6.
This solution is among the most innovative on the European market, featuring both very good technical parameters and wide possibilities of application. The same windows can be used as RC and bullet proof security devices while retaining the external design of standard PE78N windows. Windows can be installed both in public and residential buildings.
