The present disclosure relates to an exterior wall for tilt-up construction comprising: (a) a fascia wythe; (b) a structural wythe; (c) a layer of insulating material disposed between the fascia wythe and the structural wythe; and (d) a thermal break in contact with at least the structural wythe, the thermal break comprising an elongate body comprising one or more thermal insulating materials, a first surface suitable for mounting a fixture, a second surface opposite the first surface, a first contacting surface, and a second contacting surface opposite the first contacting surface, the first contacting surface and the second contacting surface extending between the first surface and the second surface. The elongate body is substantially made of a non-wood material, and the structural wythe contacts at least a portion of the second contacting surface. The present disclosure further relates to methods of constructing an exterior wall comprising a thermal break.

The disclosure relates to a formwork device, in particular for arrangement between two bulkhead partitions of a battery mould, for manufacturing construction elements, in particular precast concrete elements, said formwork device comprising two formwork elements which each have a formwork front side for applying concrete and a formwork rear side, wherein the formwork elements are pivotably connected to one another at first end regions so that the formwork elements can be transferred from a vertical state into a horizontal state. The formwork device also comprises a spreading device for spreading apart second end regions of the formwork elements starting from the vertical state of the formwork elements, said second end regions being opposite the articulated connection. The disclosure also relates to: a battery mould comprising two bulkhead partitions and a formwork device according to the disclosure; a method for manufacturing a precast concrete element with the aid of the formwork device according to the disclosure; and a method for preparing the manufacture of a precast concrete element with the aid of the formwork device according to the disclosure.
