Thursday 18.09.2014 IMS successfully tested an A-0 window that was 2400mm tall. This 2,4 meter window is the largest window we have ever tested in our furnace. The window is 1200mm wide and since IMS guarantee for the optic quality and the window can be supplied with heating it is suitable as a bridge-window. Since we have our own inn house test facility with a furnace, we are able to perform several fire tests and therefore optimize the size on all our windows and doors. We are currently also working on a B-classed glassed internal wall, a Jet-fire or J-class window and a A-60 glassed escape hatch.
