ABSTRACT:
A prefabricated construction for building walls, comprising a pair of panel elements each having a wall portion and a plurality of stiffening rib portions extending along the wall portion. At least some of the rib portions on each panel element include recesses on edges thereof which are spaced from the wall portions. The pair of panel elements face each other with substantial juxtaposition between the rib portions of one of the pairs of elements with those of the other of the pair of elements, and with the wall portions spaced from each other. The space between the wall portions and juxtaposed rib portions are substantially filled with expanded synthetic material to form a wall element and conduit passages are defined in the synthetic material between the pair of panel elements and adjacent the recesses in the rib portions.
