The removable formwork set comprises the tray with sandwich wall blank located in its internal cavity and the form cover. The sandwich wall blank is composed of at least one decorative and at least one heat insulating layer interconnected by reinforcement. The tray comprises a bottom and side pieces positioned at an obtuse angle to the bottom plane and detachable end panels positioned perpendicular to the tray bottom at its ends. The cover comprises a top sheet and side pieces positioned at an obtuse angle to the top sheet plane. The tray has grooves and the formwork cover features interconnection locks. The cover length is less than the tray length by the value equal to the building ceiling height. Use of the formwork set make easier concreting when erecting cast-in-situ skeleton buildings with decorative wall front surface.
