Abstract

A thermoplastic-based building panel, such as a floor panel. The building panel includes an upper layer arrangement, a lower layer arrangement, and a balancing layer provided between the lower and the upper layer arrangement. The building panel further includes a groove arrangement including grooves. A thermoplastic-based building panel including an upper layer arrangement and a balancing layer which is a bottom layer of the building panel. The building panel includes a groove arrangement, wherein a major portion of the grooves therein is provided in the balancing layer only. A thermoplastic-based building panel including a mechanical locking system for horizontally and/or vertically locking the building panel to an adjacent building panel. The mechanical locking system includes a cooperating surface which is situated in a balancing layer and is configured to cooperate with a cooperating surface of an adjacent building panel.

Claims21

Dependent claims

A thermoplastic-based building panel comprising:

an upper layer arrangement,
a balancing layer comprising a thermoplastic polymer, and
a mechanical locking system for horizontally and/or vertically locking the building panel to an adjacent building panel, the mechanical locking system comprising a first cooperating surface provided in an edge portion of the building panel and being configured to cooperate with a second cooperating surface of the adjacent building panel,
wherein the first cooperating surface of the mechanical locking system is at least partially situated in the balancing layer,
wherein the balancing layer at least partially extends through a locking groove, and/or through a portion of a locking element extending vertically higher than an uppermost surface of a strip, the strip extending horizontally beyond an upper edge of the edge portion, the locking element being configured to engage with the locking groove of said adjacent building panel for horizontal locking,
wherein:
(i) the balancing layer entirely extends vertically below an uppermost surface of the locking groove;
and/or (ii) the balancing layer entirely extends vertically above the uppermost surface of the strip.
