FOAMED HOLLOW CHAMBER PROFILES
A method for manufacturing a foamed profile including one or more longitudinal hollow chambers having a closed section, including (a) extruding a first polymer composition, in the presence of one or more first foaming agents, into a foamed base profile having a polygonal section, preferably a rectangular section, the first polymer composition including one or more (co)polyesters, (b) cooling the foamed base profile, (c) creating a trench along the length of the foamed base profile by removing material, preferably by means of milling, cutting, laser or thermofusion, the trench forming two parallel branches in the foamed base profile, each of the branches including an outer surface opposite the trench and an inner surface facing the trench, and (d) extruding, inside the trench, a second polymer composition which may or may not be identical to the first polymer composition, preferably in the presence of one or more second foaming agents, into a spacer at at least one location between the two inner surfaces of the two branches of the trench, so as to form at least one closed hollow chamber inside the trench. The disclosure also related to foamed profiles including one or more longitudinal hollow chambers having a closed section, in particular insulators for reducing the thermal bridge effect between two connected building elements.
