A pressure relief wall assembly has a wall panel, one end of which is permanently secured to a frame. A plurality of elements secure a second end of the wall panel to the frame, and these elements fail when an excess pressure is applied to the wall panel. A retaining member is provided so that, when excess pressure is applied to one of the two sides of the wall panel, the second end of the wall panel is retained until a further increase of pressure occurs. The retaining member then releases the second end of the wall panel. This enables the wall assembly to be designed for different release pressures in blow-in and blow-out modes, so that no excess load is applied to a support frame in either mode.

A pressure relief wall assembly comprising a wall panel the terminology having ends and sides with a central portion of the panel, in use, being permanently secured to a frame, and fastener means which comprises: securing means comprising a plurality of elements, which, in use, releasably fasten the ends of the wall panel to the frame and which fail when a first excess pressure is applied to either side of the wall panel; and at either end of the panel a retaining means each of which retaining means comprises a retaining member and an engagement member mounted, in use, between a respective end of the panel and the frame, with the retaining member including a portion extending in the direction parallel to the plane of the wall panel and abutting the engagement member, whereby for deflection of the respective panel end in one direction the retaining member leaves the retaining member without obstructing the deflection, and for deflection in the other direction, after failure of said elements, the retaining member retains the respective end of the wall panel and prevents any substantial movement thereof, and the retaining member deflects so as to be released from the respective engagement member, thereby releasing the respective end to permit the applied pressure to dissipate, when a second excess pressure greater than the first excess pressure is applied to the other side of the panel after a further increase in the pressure applied to the wall panel in said other direction above a second excess pressure greater than the first excess pressure.
