An HVAC air handling enclosure is comprised of individual panel assemblies each of which are fabricated from two panels or skins that are held together by double-sided adhesive tape. Adjacent panel assemblies are connected by a metal tongue-and-groove joint that relies on that same tape as a thermal break at the joint. After assembly, the thermal break and the tongue and groove elements of the joint are completely hidden from view. Moreover, the joint includes an internal cavity that can take up surplus sealant that may ooze out from within the tongue-and-groove joint during assembly, whereby the surplus sealant also remains hidden.
