Abstract: Door frames, frame kits, component parts, jamb coverings, and depth extenders, all constructed with fiber reinforced pultruded structures, for entrance doors to buildings, both garage entrance doors and personnel entry doors. Some embodiments have a closed back wall. Others have an open cavity at the back wall to receive a reinforcing substrate. Some embodiments include a pultruded nosing block. Some embodiments comprise a pultruded depth extender, mountable on a jamb base to extend the depth of a door jamb. A mounting finger and a locking stud on the depth extender are mountable in cavities in the jamb base. A depth extender can be used to extend the depth of either a garage door frame or a personnel entry door frame. In an in-swing door frame, a door latch-side abutment surface is located on the side wall of the jamb base.

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.
