A set of extruded panels is provided which can be assembled on site to create a permanent form-work for concrete. The set includes inside and outside extruded side wall panels which are arranged to be connected edge to edge to form inside and outside walls. Longitudinally spaced connecting wall panels span between the inside and outside walls at spaced positions across the width of the walls to hold the walls apart and define a hollow interior therebetween including a plurality of interconnected cells with a plurality of holes for communication of concrete and reinforcing bars between each cell and the next. Each connecting wall panel has T-shaped connectors at each edge for attachment to corresponding C-shaped receptacles on the side wall panels. Rigid foam insulation is inserted at the outside wall. The inside wall panels are arranged to support without bowing cast concrete poured into the interior within each cell and three different arrangements are shown to support the inside wall each including a wall portion at right angles to the inside wall and between the connecting walls. In one, an integral double wall is provided. In a second, a short support wall extends to a supplementary wall parallel to the inside wall and in the third, a support wall identical to the connector walls spans between the inside and outside walls.
