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.

The invention claimed is: 1. An enclosure for HVAC equipment, wherein the enclosure has a tongue-and-groove joint the enclosure comprising: a first outer panel; an outer groove flange; an outer groove edge extending between the first outer panel and the outer groove flange; a first inner panel; an inner groove flange; an inner groove edge extending between the first inner panel and the inner groove flange; a first strip of tape joining the outer groove flange and the inner groove flange such that the outer groove flange and the inner groove flange define a groove therebetween; a second outer panel; an outer tongue flange; an outer tongue edge extending between the second outer panel and the outer tongue flange; a second inner panel; an inner tongue flange; an inner tongue edge extending between the second inner panel and the inner tongue flange; and a second strip of tape joining the outer tongue flange and the inner tongue flange to provide a tongue that is disposed within the groove. 2. The enclosure of claim 1, wherein the first outer panel and the outer groove flange is a first unitary piece, the first inner panel and the inner groove flange is a second unitary piece, the second outer panel and the outer tongue flange is a third unitary piece, and the second inner panel and the inner tongue flange is a fourth unitary piece. 3. The enclosure of claim 1, wherein the first outer panel and the second outer panel abut each other in direct contact. 4. The enclosure of claim 1, wherein the first strip of tape and the second strip of tape each have adhesive on both sides thereof. 5. The enclosure of claim 1, wherein the first strip of tape helps hold the first inner panel and the first outer panel together. 6. The enclosure of claim 1, wherein the second strip of tape helps hold the second inner panel and the second outer panel together. 7. The enclosure of claim 1, wherein the first strip of tape is held in tension between the outer groove flange and the inner groove flange. 8. The enclosure of claim 1, wherein the second strip of tape is held in compression between the outer tongue flange and the inner tongue flange. 9. The enclosure of claim 1, wherein the first outer panel and the outer groove edge define an acute angle. 10. The enclosure of claim 9, wherein the acute angle is greater than 80-degrees. 11. The enclosure of claim 1, wherein the second outer panel and the outer tongue edge define an acute angle. 12. The enclosure of claim 11, wherein the acute angle is greater than 80-degrees. 13. The enclosure of claim 1, further comprising a sealant bonding the first outer panel to the second outer panel. 14. The enclosure of claim 1, further comprising a first insulating core interposed between the first outer panel and the first inner panel; and a second insulating core interposed between the second outer panel and the second inner panel.
