ABSTRACT:
A door has a pair of outer skins separated by a frame to form a hollow space therebetween. An expandable spacer core is connected between the pair of skins. The expandable spacer core has a plurality of elongated members each oriented perpendicular to both outer skins. A plurality of expandable core liners extend between elongated members to position the elongated members with respect to each other and to the outer skin. The expandable spacer cores are formed by gluing strips of expandable core liners between corrugated layers so that the corrugated layers are held together by the expandable core liners. The corrugated layers are cut in a direction across the expandable core liners. Once the expandable spacer cores are formed, an adhesive is placed on the edges of the expandable spacer core and the expandable spacer core is affixed to the inner side of the outer skins of the door.
