    Patent number: 4205106
    Abstract: A light weight door for a caravan is made as a sandwich from two panels with an infilling of a wooden frame consisting of rails and stiles which are not jointed together, and with blocks of expanded polystyrene filling the spaces between the rails and stiles, these blocks being initially thicker than that of the wooden frame parts, and all of the parts being bonded together so that the blocks become compressed. The bonding makes the door concave convex at the latch edge but planar at the hinge edge. The door has rounded corners.
