Abstract
There is described a profiled sash section for a window sash holding a window pane and intended for being installed in an outer frame of a blast resistant window. The sash section includes a main member enabling inter-engagement between the profiled sash member and the outer frame a window pane holding member for accommodating and securing an end portion of said window pane in the profiled sash member, and a reinforcing member designed to support the end portion of the window pane and to transmit blast pressure, if incidentally applied to the window pane, to the main member. For at least partially absorbing blast pressure energy applied to the window pane, the sash section is provided with damping means for deforming up to predetermined limit. Also described is a blast-resistant framework for a casement window, including the window sash assembled from the mentioned profiled sash sections and adapted for rigidly and air-tightly securing the window pane in the holders of the profiled sash members.
