ABSTRACT:
A generally flat structural panel for building construction includes a center insulating core such as of foam and opposed outer facings, or sheets, with one or more metal strips disposed within and extending the length of the panel and bonded to the panel's insulating core and to one of its outer facings. At least one of the outer facings is composite gypsum, concrete or cement which provides good tensile strength and high fire, environmental and insect resistance as well as low cost, but only limited bending strength. Metal strips of either aluminum or steel incorporated in the panel and bonded to the insulating core and to the gypsum, concrete or cement facing extend substantially the entire length of the panel and substantially increase the panel's bending strength without noticeably increasing its weight, permitting the panel to be used as a loadbearing structural member such as in a roof or floor as well as an outer wall capable of withstanding wind loads and earth loads when used as a basement wall panel.
