Abstract of the Disclosure A door-casing element comprises an elongated inner metallic profile, an elongated outer metallic profile parallel to and spaced outwardly from the inner profile, an elongated thermally relatively nonconductive connector between and engaging both of the profiles, and ratchet formations securing the profiles in spaced-apart relationship to the connector. The inner and outer profiles are spaced so it is possible to form them of aluminum, which can be made with an attractive anodized finish and which can be used in outdoors applications without danger of rust. The thermally nonconductive connector, which can be made of rigid and fire-resistant gypsum fibers, will not transmit heat effectively between the two profiles so that the resultant casing can easily be of high firecode rating.
