Abstract: 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.

Abstract: A door frame employs extruded aluminum jamb moldings, including extruded jambs, or jamb cover moldings in combination with jamb substrates. The extruded aluminum molding includes a mounting fin kerf. The kerf is generally boot-shaped, having an inwardly-disposed foot portion and an opening having an ankle-shaped cross-section. The mounting fin can be generally rigid, such as an extruded aluminum fin or a generally rigid polymeric fin. The kerf, in combination with the mounting fin, which has a bulbous rigid base, facilitates locking the fin in an erect orientation at about 75 degrees to about 90 degrees relative to the jamb body or the jamb substrate. The kerf/fin combination further provides improved ease of release of the fin from the erect orientation and facilitates rotating/retracting the fin into contact with the jamb body or jamb substrate.

Abstract: A fiber-reinforced pultruded polymeric door frame has side and header jamb assemblies which are essentially devoid of wood and other materials which are susceptible to being damaged by the affects of weather. Such jamb assembly generally includes a pultruded jamb which has a rearwardly- and/or downwardly opening cavity. Inserts are received in the jamb cavities and extend downwardly and/or rearwardly from the pultruded jambs. The inserts can receive nails or screws, whereby the door frame can be mounted to building framing members at the doorway rough opening.

Abstract: Metal cladding as jamb cover assemblies and mullion cover assemblies, for door frames and mullions, using extrusions as cladding over substrates. A jamb cover assembly includes a jamb plate, a nosing, and a nailing fin. The nailing fin extends from a distal side of the assembly. Accordingly, the frame can be secured in a rough opening of a building with the nosing assembled to the jamb plate, and using the nailing fin for the securement, without any assembly or disassembly of the frame at the construction site. Regarding the mullion cover assembly, first and second jamb plates are on opposing sides of a mullion substrate. A mullion nosing is assembled to the jamb plates, and bridges the jamb plates to join together the two jamb plates and the nosing, to provide complete overlayment of the outer surface of the mullion substrate and to space the front panel of the nosing from the outer surface of the substrate.

Abstract: A door frame which employs jambs or jamb assemblies which are essentially devoid of wood and other materials which are susceptible to being damaged by the affects of weather. The side jambs are fabricated of e.g. extruded aluminum moldings which extend an underlying floor/substrate to the header, and can be fabricated from a common-profile extruded aluminum molding. The jambs can also have an e.g. polymeric insert assembled thereto which can receive nails or screws, optionally without pre-drilling, in a similar manner as wood receives nails or screws. The jambs can further include a nosing either integral with, or snap assemblable thereto. The molding can further include a nail fin kerf which accepts a rigid or a flexible nailing fin.

Abstract: Fiber reinforced polymeric pultruded cladding as jamb cover elements and mullion cover elements, for door frames and mullions, using pultruded structures as cladding over substrates. A jamb cover assembly includes a pultruded jamb plate and/or a pultruded nosing, and a mounting fin. The mounting fin extends from a distal side of the assembly. The frame can be secured in a doorway rough opening with the nosing assembled to the jamb plate, using the mounting fin for initial securement, optionally without assembly or disassembly of the frame at the construction site. Pultruded substrate covering covers both the outer surface and opposing sides of a mullion substrate. A pultruded mullion nosing is assembled to the substrate covering, and overlies part of the substrate cover, providing complete pultruded overlayment of the outer surface of the mullion substrate and spacing the front panel of the nosing from the outer surface of the substrate.
