A wall panel assembly with a sealed joint. The sealed joint is virtually airtight even in an enclosure having an ambient air pressure substantially greater than the air pressure outside the enclosure, such as an air handling cabinet. Each joint is comprised of two abutting looped joint edges in combination with a Y-shaped seal. The looped joint edge provides added structural rigidity to the panels, and the enlarged looped ends on the joint edges enclose and protect the seal therebetween from exposure to the elements. The seal itself not only withstands positive internal air pressure but is actually improved thereby. Abutting joint edges of adjacent wall panels create a narrow channel for receiving the longitudinal flange portion of the seal, and a broader Vshaped channel to receive the enlarged body portion of the seal. In this way, the body portion of the seal is seated in a channel so that internal pressure exerted against the seal will cause the seal to appressingly engage the channel. Thus, increased internal air pressure improves the sealed joint rather than compromising it. The seal can be provided with a longitudinal slit for receiving the edge of internal divider panels. Adjacent wall panels are joined by fasteners intersecting the outwardly extending looped portions of the joint edges. In this way, the fasteners are accessible from the outside, and the integrity of the seal is preserved. |
