Spacing means for wall panels for preventing the buckling of said panels due to changes in climatic temperature, the panels having slotted portions along a top edge and one side thereof for receiving a flange mounted along the bottom edge and the other side of an adjacent panel, the improvement consisting of breakable spacing members extending at approximately right angle to the panel and mounted in proximity of the slotted portions whereby upon mounting one panel upon another, the spacing members of the upper panel engages and rests on the top edge of the flange of the lower panel in predetermined spaced relation to the upper edge portion of the slotted portion, said space permitting the expansion due to temperature changes of the panels without buckling same.
