Abstract
Abstract A stack of expanded foam blocks form a wall and define interconnected vertical and horizontal internal cavities which receive reinforcing rods, and concrete is pumped into the cavities to form an internal grid of reinforced concrete posts and beams. A set of opposing frame sections or shells clamp the blocks around a rough window or door opening and cooperate to define a frame cavity which receives the concrete pumped into the internal cavities to form a concrete window or door frame integrally connected to the concrete grid. In one embodiment, the opposing window frame shells remain with the wall and form a smooth seat for a window unit, and in another embodiment, the window or door shells are removed from the wall to form a concrete seat for the window or door unit.
