An enclosed structure, such as a patio enclosure, sunroom, or solarium, is attachable to the exterior wall of a building, has a high proportion of windows and a roof, and constructed from a framework of composite members and insulating wall panels, wherein header and post beams of the room wall assemblies are extruded from material having improved thermal characteristics and stability. Importantly, the beams enable wire services to be routed in concealed fashion from a power source associated with the building to accessible locations in the room and remote to the building. The header and post beams are configured to enable the wire services to be concealed but yet accessible for repair and routing through the header beams and into one or more post beams, as desired.
