The protected trademarks GEWE-dur® and GEWE-dur®-H are single
panes of safety glass and meet all requirements which are
made on modern thermally toughened glass: 4–5 x greater flex
resistance compared to untreated flat glass (stable tension status),
increased resistance to impact, shock and hail, thermal shock
resistance, lower risk of injury, i. e. with excessive mechanical
stress the pane breaks into blunt-edged, loosely connected fragments.
GEWE-dur®-H is a special, thermally toughened, hot-stored sodalime
single pane safety glass produced in accordance with
EN14179, for which spontaneous breakage can be largely excluded.
Special application safety has to be guaranteed, especially in the
construction sector. Therefore this product, which undergoes the
heat soak test, corresponds with the standards of the German construction
code and as such is a regulated construction product,
which in individual cases would not require special approval.
