Abstract
A mineral-based panel including a mineral-based core and at least one groove. The at least one groove may be provided in a rear side of the panel. The mineral-based panels may be floor panel, a building panel, a wall panel, a ceiling panel or a furniture panel. A method for forming such grooves in a mineral-based panel. Furthermore, a mineral-based panel including a mineral-based core and polymer-based lower layer(s) attached to the core. A locking system of the panel includes a strip extending horizontally beyond an upper portion of the panel, and a horizontal portion of the strip is entirely formed in the polymer-based lower layer(s).
Claims36
A mineral-based floor panel comprising
- a mineral-based core,
- wherein the mineral-based core comprises magnesium oxide,
- wherein the mineral-based core further comprises magnesium chloride and/or magnesium sulphate,
- wherein the panel comprises at least one groove, and
- wherein the at least one groove is provided in a rear side of the panel, between two coplanar lowermost surfaces of the floor panel.
A mineral-based panel comprising
- a mineral-based core, and
- a lower arrangement comprising at least one polymer-based lower layer, the lower arrangement being attached to a lower side of the mineral-based core,
- wherein the mineral-based panel further comprises a locking system for horizontal and/or vertical locking, said locking system comprising a strip extending horizontally beyond an upper portion of the mineral-based panel,
- wherein at least a horizontal portion of the strip is entirely formed in the lower arrangement, and
- wherein a horizontal and/or vertical locking surface is provided on the at least one polymer-based lower layer, the horizontal and/or vertical locking surface being configured, when locking the panel to a similar panel, to horizontally and/or vertically lock to a second locking system of the similar panel.
