Abstract

The invention relates to a method for moulding by injection or extrusion, in which between two bodies or media at different temperatures there is a free space or gap. According to the invention, set in said free space or gap is a barrier made of thermally insulating material (C), which comprises at least one insulating material having index of thermal conductivity lower than that of dry air at 0°C and is designed to reduce the thermal dispersion linked both to the convective motions and/ or heat conduction of air and to irradiation, which depends upon the characteristics of the body at a higher temperature.
