ABSTRACT OF THE DISCLOSURE: There is disclosed an insulating formwork for casting a concrete wall, the formwork having a pair of sidewalls each of which is made-up of a plurality of coplanar edge-abutting modular panels made of insulating foam material. Each panel has upper and lower edges with coplanar slits provided therealong, and a pair of vertical end edges respectively provided with a tongue-and-groove to form vertical tongue-and-groove joints with other like adjoining panels. A rabbet opens onto the panel inner face and onto the panel lower edge. The panels are interconnected by a first group of angle-irons having vertical branches fitting into the upward slits, of the panels, and horizontal branches, pierced with holes, extending toward the panel inner face. The panels are also interconnected by a second group of angle-irons having vertical branches fitting into the downward slits of the panels and horizontal branches, also perced with holes, extending toward the panel inner face and overlapping the horizontal branches of the angle-irons of the first group. The holes register together and the tie-rods hold the side- walls together. The tie-rods have a central portion between the sidewalls and bent end portions extending through the panels. Elbows between the portions fit into the rabbets.
