Abstract
A building panel formed of two surface layers of metal or plastic spaced by an insulating core of polyurethane foam. Each panel has a male side edge and a female side edge which can be joined in side by side fashion to form an extended building structure. A cover strip can be installed between adjacent panels to mask the junction line between panels.
