A wall opening frame member (10, 79) for framing doors, windows, and the like having an exterior side (14) and an interior side (16). The frame member (10) has a metal frame (18) that preferably has at least one structural heat transfer barrier (52, 62) whereby no unbroken metallic heat transfer path exists between the exterior side (14) and the interior side (16). A wood facing (20) is adapted to cover all substantial interior surfaces of the metal frame (18) when the metal frame (18) is in use. Means are provided for attaching wood facing (20) to the interior surfaces of the metal frame (18) so that no substantial surface of the metal frame (18) is exposed to the inside ambient air and the transfer of heat between the exterior side and the interior ambient air of the frame member (10) is inhibited. Preferably, the means for attaching the wood facing (20) includes an elastic and deformable foam body (68) attached on opposite side surfaces by a selected adhesive to the wood facing (20) and the metal frame (18) to further inhibit heat flow and to compensate for temperature and humidity caused dimensional changes in the metal frame (18) and the wood facing (20).
