The invention relates to a fire and blast resistant window assembly, comprising a frame adapted to be built into a window aperture, a glazing system and a front insulating glass unit. The assembly is characterized in that the front insulating glass unit is mounted on the frame such that a thermal break is formed therebetween, the frame contains a metal framework, which delimits a mounting aperture for the glazing system, wherein separator plates are welded to the framework, along the perimeter thereof, with spaces between the separator plates, and the glazing system comprises a first and a second glazing unit. Each of the glazing units comprises a support profile and a glazing sheet, which is inserted in the support profile and clamped thereto from the inside by glazing beads, wherein a thermal break is formed therebetween. The first glazing unit is welded to the separator plates in the front part of the framework of the frame, and the second glazing unit is sealingly fastened to the framework of the frame in the rear part thereof. The invention also relates to a method of installing the above window assembly and provides a window assembly with improved fire and blast resistant properties which is easier to install. |
