RC3 PROTECTION AGAINST FORCED ENTRY WITH IN FRONT OF WALL INSTALLATION SYSTEM ISO-TOP WINFRAMER „TYPE 3”
The IN FRONT OF WALL INSTALLATION SYSTEM ISO-TOP WINFRAMER „TYPE 3” from ISO-Chemie was tested by Holzforschung Austria (HFA) and certified as an intrusion-resistant component to resistance class RC3. The system was already RC2-tested, but has now proven its suitability for the installation of intrusion-resistant windows and glazed doors in front of the wall – an even more stringent class.
