A thermoplastic-based building panel comprising a balancing layer

Abstract

The disclosure relates to a thermoplastic-based building panel (1), such as a floor panel. The building panel comprises an upper layer arrangement (2), a lower layer arrangement (3), and a balancing layer (4) provided between the lower and the 5 upper layer arrangement. The building panel further comprises a groove arrangement (10) comprising grooves (11). Moreover, the disclosure relates to a thermoplastic-based building panel (1) comprising an upper layer arrangement and a balancing layer which is a bottom layer of the building panel. The building panel comprises a groove arrangement, wherein a major portion of the grooves therein is 10 provided in the balancing layer only. Finally, the disclosure relates to a thermoplastic- based building panel (1) comprising a mechanical locking system for horizontally and / or vertically locking the building panel to an adjacent building panel. The mechanical locking system comprises a cooperating surface which is situated in a balancing layer and is configured to cooperate with a cooperating surface of an 15 adjacent building panel.
