237224-161 ABSTRACT A window, door or fixed glazing arrangement is provided which comprises a pane and frame structures having a bombardment- resistant construction. The frame structure has a movable portion and a fixed portion which are provided at the outside and/or inside with extruded bombardment resistant profile bars consisting of an aluminium alloy. In the window or door there is a gap between the fixed portion of the frame structure and the movable portion of the frame structure in the region of the bombardment- resistant profile bars. The gap is of labyrinth-like configuration and has a step extending parallel or approximately parallel to the plane of the window or door. The bombardment- resistant profile bars have internal chambers which extend over the entire length of the profile bars, the boundary surfaces of the chambers extend at an acute angle relative to the plane of the window, door or fixed glazing arrangement. In another embodiment, the profile bars are of a multi-part configuration and have a plurality of inner chambers arranged parallel to one another in a row. The row extends over the entire region of the bombardment- resistant profile, at an acute angle relative to the plane of the window, door or fixed glazing arrangement.
