Joints in a panel wall construction are provided with an internal seal of greatly enhanced airtightness and of enhanced structural strength. This is achieved by forming the panels with the core thereof recessed inwardly from the edges of the skins so that when the panels are positioned in assembled relation in a channel member, a longitudinally extending cavity is provided between the skins. A hardenable filler material, such as foam, is injected into the cavity to completely fill the cavity as well as any cracks or gaps which may exist between the channel member and the skins of the panel.

A method of forming a strong airtight joint between a pair of adjoining insulated panels having adjacent longitudinal edges positioned in and interconnected by an elongate channel member having respective pairs of opposing spaced apart legs for receiving the panels therebetween and having a web port

A method of forming a strong airtight joint between a pair of adjoining insulated panels having adjacent longitudinal edges positioned in and interconnected by an elongate channel member having respective pairs of opposing spaced apart legs for receiving the panels therebetween and having a web portion extending between and interconnecting the pairs of opposing legs, and the panels each having an insulated core and a pair of parallel skins on opposite sides of the core defining the exterior surfaces of the panel, and said method comprising forming the panels with the insulated core thereof recessed inwardly from the pair of skins along at least one longitudinal edge of the panels, positioning the pair of adjoining panels with the projecting longitudinal edge portions of the skins thereof extending into the channel member and positioned in opposing contacting relation with the adjacent legs of the channel member and with the recessed cores thereof forming respective longitudinally extending internal cavities within the channel member on opposite sides of the web portion, forming a hole in the channel member penetrating the web portion and communicating with the respective cavities on opposite sides of the web portion, injecting a hardenable expandable foam material simultaneously into the respective cavities through said hole and expanding the foam material so as to completely fill the cavities while also filling any cracks or gaps which may exist between the channel member and adjacent portions of the skins of the panels to thereby produce an airtight seal between the pair of panels, whereeby upon hardening of the foam material in the cavities a bond is formed between the channel member and the adjacent portion of the skins to thereby provide enchanced structural strength in the joint.
