Panel wall construction having airtight joint and method of forming same

摘要

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.
