Abstract
Abstract An insulated building panel unit consisting of a metal liner sheet, a layer of rigid foamed plastic material selfadheared to the liner sheet and a facing sheet adhesively secured to the layer of foamed plastic material. Selected regions of the surface of the foamed plastic material are modified to provide essentially flat surfaces for adhesive bonding with essentially flat surfaces of the facing sheet. A method is described for making the present insulated building panel unit.
