Abstract: Simplicity is the height of invention. Glazing is simplified and reduced in cost by substantially eliminating framework for glass or other glazing material. And yet, long-life is retained, by use of an adhesive-sealant to secure the glazing to the solar absorber sheet. Differential expansion and contraction of parts does not break the glass or other glazing, or rupture metals, or crack rigid plastics.

Abstract: A low-cost building, building section or wall, usable as a house, mobile home, vehicle, or part of these or other structures, having numerous parallel rows of end-joined used or new cans, each can preferably consisting of a tube and can-cover elements at ends of the tube and containing thermal insulation, which may be only dead air in the relatively small hollow can space but preferably includes loose small portions of low-cost insulating material, such as sawdust, vermiculite, cotton linters, dry sand or dust, ashes, cinders, ground bark, rice or other seed hulls. Abutting pairs of can cover elements are tightly held together by connecting means which may be bonding material (epoxy putty, solder or the like) or bands of slightly stretchable adhesive tape which encompass and adhere to portions of juxtaposed pairs of the end-joined cans. A layer of mesh sheathes one side of each group of the can rows, and the other side is sheathed with wall material which may be mesh or insulating solid panels.
