ABSTRACT:
A "Wall Member" which comprises an elongated substantially rectangular extruded mono-shell defining an inner core, extruded in indefinite length, after which it is cut to the required dimension. The shell is made of low heat expandable material and contains an insulating material therein. The shell is formed with two vertical faces one of which having a permanent building exterior finish and the other having a permanent building interior finish. This interior vertical face is also provided within its main core, with an adjacent integral conduit therein for horizontal electrical leads. The shell is additionally formed with two horizontal upper and lower faces which are adapted for engagement over one another, such as by tongue and groove. These "Wall Members" are also adapted for connecting their ends which are provided with upper and lower hard surface fins to a structural vertical member such as a Post, window or door frames or another "Wall Member". The preferred material of the outer shell of the "Wall Members" and of the "Posts" is high density extruded wood fibrous pulp and resin mixture. The insulating material for the "Wall Members"only is preferably polyurethane foam which is sprayed and formed in simultaneously as the extrusion process producing the shell occurs; or styrofoam moulded to the inside shape of the shells and is thereafter inserted therein. The Post on the other hand is filled with a solid wooden core. This "Wall Member" and "Post" make it possible to produce low cost housing projects with the minimum of labor, because these prefinished "Wall Members", together with the "Posts" apart from doors and windows will constitute the whole of all the walls.
