 | | The two corner panels each include a pair of orthogonally disposed flanges which terminate in flared, flexible lips for overlapping adjunct edges of the four panels, thereby joining the four wall panels together. |
 | | The back faces of the flanges of each of the corner panels are adhered or otherwise affixed to the wall corners so that the flared, flexible lip or each of the flanges is yieldably deformed around the edge of the adjacent panel in overlapping relationship. |
 | | Proper operation of the invention depends in part on the existence of gaps between the wall corners and the corner edges 4, 7, 12, 18 of the panels 1, 5, 9, 13. |
