An improved building system of the type having modular sections comprised of a foam-type insulation between skins is made by extending the skins beyond the end of the insulation and forming flanges upon such extensions. The flanged extensions of two wall sections to be joined are brought together and a resilient extrusion is installed around the flanges, thus forming a channel defined by the ends of the insulation, the flanged extension and the extrusion itself. This channel is "foamed-in" with more insulating material to form a rigid structure.
