The panel (1) has a central insulating core (27) made of insulating material such as foam, and sandwiched between internal and external facing plates (2, 3) made of rigid material such as plastic material. Furrow type recesses or grooves (27a) are formed on a part of a surface of the core that is in contact with one of the plates, where the grooves create square studs (27b). The insulating material of the core authorizes independent lateral displacement of the studs. The core is connected to the plate at level of a part of the studs,without providing obstacle to displacement of the studs. |
