A door frame employs jambs or jamb assemblies which are essentially devoid of materials which are susceptible of being damaged by the affects of weather. Side jambs, optionally supplemented by inserts, extend from an underlying floor/substrate to the header, and can be fabricated from e.g. common-profile extruded aluminum moldings. The inner panel of such molding, which faces across the doorway opening, can be reinforced, from a relatively lesser thickness portion thereof, by a relatively greater thickness portion of such inner panel. The jambs can have rear cavities which receive inserts which can receive nails and/or screws. The inserts can be held in the cavities by protuberances and cooperating recesses which collectively balance front-to-rear loading forces. The rear cavity and the insert are configured such that loads interacting between the cavity side panels and the insert are generally balanced, front-to-rear, by protuberances and recesses on the respective side panels and insert.
