Abstract: The vapor exhaust system is used in a wall section which includes a lower plate member (10) and an upper plate member (18), both of which have longitudinal grooves (12, 20) therein. Connected between the upper and lower plate members are a plurality of vertical stud members (26). Cut-out portions are provided in the stud members (26) as well as in the upper plate member (18), permitting air trapped between the studs to move out of the wall section through the cut-out portions. Exterior and interior facing members (54, 60) may be positioned on the wall sections. An opening (56) is provided in a lower portion of the exterior facing member (54). A pump (40) may be used to assist in the movement of air through the wall section.

Abstract: Building construction system utilizing a modular or component type construction in which the components are prefabricated at a plant location and then assembled at a job or building site. The system utilizes wall, door, plumbing, over-window, under-window and filler type components together with conventional foundation structure and premade roof trusses. The components include facing members with the vertical edges of the facings being kerfed to receive a spline. The facing members are overlaid with plastic and treated with fire retardant.
