ABSTRACT:
A fire rated wall/door system 10 comprises a transparent panel 12 which is supported by a frame means 23 for protecting the peripheral edge 40 of the panel 12 from delamination. Further, mounting means 32 mount the frame 23 in a wall 30 so as to accommodate expansion of the panel 12 and frame 23 to prevent panel bowing with resultant delamination of panel 12 and premature failure.
