Abstract

An improved building panel. The panel includes a pair of identically formed facing sheets arranged with adjacent edges extending parallel and spaced apart to one another and an insulating core between the facing sheets to minimize the transfer of heat from one facing sheet to the other through the space therebetween. The panel further includes a channel member assembly for receiving the adjacent edges of the sheets to form a joint between the sheets. The channel member assembly includes at least one pair of opposing legs extending parallel and spaced apart to one another for interconnecting the sheets with one another and a web portion extending between interconnecting the opposing legs. The web portion includes an insulating bridge member positioned between the opposing legs adjoining the pair of facing sheets to minimize the transfer of heat from one facing sheet to the other through the web portion and defining a noncontinuous space. The web portion includes a pair of structural elements offset with respect to one another and aligned along diagonally opposite edges of the insulating bridge member, at least one of the elements being adapted to abut the edge portion of the insulating core, thereby eliminating a substantial portion of the noncontinuous space to minimize the transfer of heat from one facing sheet to the other through the space.
