A climate seal frame member assembly for constructing a frame around an ingress/egress door to a structure. The assembly includes an elongate, two-part member where one part is extruded from a foamed PVC material and the other part is milled from an elongate piece of lumber. The PVC member is exposed to the outdoor environment when installed, and the milled wood part, isolated from the outdoor weather by a weather-strip, provides a wooden surface for receiving paint or stain. The cross sectional shape of the PVC part is extruded to incorporate a door stop and a tongue for engaging with a matching grove milled into the wooden part. The system is formed by extruding the PVC member, milling the lumber, applying an adhesive where the PVC member joins the wooden member, joining the parts along the edges having adhesive, and nailing the two members together.
