Abstract
A frameless air handling enclosure is made possible by the use of double-flanged edges on the enclosure's side and bottom panels. The edge configuration provides reinforcement and rigidity to an otherwise flexible panel and also provides a mating surface for fastening the panels together. The enclosure includes an access opening that is covered by a removable access panel having a lining of sound and thermal insulating material. The access panel is installed by first sliding it upward into engagement with a top flange retainer and then sliding it back down into engagement with a bottom flange retainer. Upon engagement with both flange retainers, the lining of insulation is compressed against the perimeter of the access opening. This compression fit not only helps hold the access panel firmly in place but also provides a weathertight seal around the perimeter of the opening.
