1. A modular wall that is a substantially linear permanent external formwork of a building, the modular wall having a length and a height, and comprising:
a series of outer panels made of a thermoplastic polymer, each of the outer panels having a first end and an opposite end;
a series of inner panels substantially parallel to the outer panels and made of the thermoplastic polymer or another thermoplastic polymer, each of the inner panels having a first end and an opposite end;
reinforcing metal pipes connecting each outer panel to a corresponding inner panel;
a first end of a first outer panel (a) is configured to fit into an opposite end of a second outer panel to form a first locking connection by using an option of a sliding motion and (b) is configured to fit into the opposite end of the second outer panel by using an option of an end to end joining motion that includes positioning the first end of the first outer panel and the opposite end of the second outer panel facing each other at an angle and then joining the first outer panel,
a first end of a first inner panel (a) is configured to fit into an opposite end of a second inner panel to form a second locking connection by using an option of a sliding motion and (b) is configured to fit into the opposite end of the second inner panel by using an option of an end to end joining motion that includes positioning the first end of the first outer panel and the opposite end of the second inner panel facing each other at an angle and then joining the first inner panel to the second inner panel,
wherein the inner panels and the outer panels are configured to remain in place as a permanent structure after a casting of concrete,
wherein each of (i) the sliding motion that forms the first locking connection and (ii) the sliding motion that forms the second locking connection is in a direction substantially parallel to the height of the modular wall and wherein each of the end to end joining motions is in a direction substantially parallel to the length of the modular wall; and
wherein each of the outer panels and each of the inner panels comprise two substantially parallel walls separated by a pattern of reinforcing ribs that together with the substantially parallel walls define spaces for heat insulation.
