In a formwork assembly for concrete wall structures side wall portions are provided at their edges with grooves and projections engageable therein for securing side wall portions together in a proper position, with the side wall portions being connected by connecting members and possibly end wall portions as required. On their inside surface, each side wall portion has engagement means to which the connecting members can be secured in the appropriate position. The engagement means may be formed by interengaging recesses and raised portions, ball portions and ball-receiving sockets or shallow detent grooves. Adhesive may also be employed for additional strength. The side wall portions may be used as insulating panels for walls, roof and floors.
