Prefabricated formwork elements for the construction of external walls of buildings comprise at least one pair of panels (1, 2) of heat-insulating material which are intended to be maintained in parallel relation in order to delimit between them a space (3) which is intended to be filled with concrete, each panel (1, 2) being reinforced by horizontal stiffeners (4) and shores (5) being provided for maintaining the two panels in a vertical position and in spaced relation. The shores (5) are removably attached to the horizontal stiffeners (4) of one (2) of the panels, the panels being maintained in spaced relation by connecting the stiffeners (4) of one of the panels to the stiffeners of the other panel.
