Title
(EN) A MINERAL-BASED PANEL COMPRISING GROOVES AND A METHOD FOR FORMING GROOVES
(FR) PANNEAU À BASE DE MINÉRAUX COMPRENANT DES RAINURES ET PROCÉDÉ DE FORMATION DE RAINURES
Abstract
(EN)
There is disclosed a mineral-based floor panel (1) comprising a mineral-based core, wherein the panel comprises at least one groove (19). The at least one groove (19) may be provided in a rear side (4) of the panel. There is also disclosed other such mineral-based panels, such as a building panel, a wall panel, a ceiling panel or a furniture panel. There is also disclosed a method for forming such grooves (19) in a mineral-based panel.Furthermore, there is disclosed a mineral-based panel (1) comprising a mineral-based core and polymer-based lower layer(s)attached to the core. A locking system of the panel comprises a strip extending horizontally beyond an upper portion of the panel, wherein at least a horizontal portion of the strip is entirely formed in the polymer-based lower layer(s).
(FR)
L'invention concerne un panneau (1) de plancher à base de minéraux comprenant une partie centrale à base de minéraux, le panneau comprenant au moins une rainure (19). La ou les rainures (19) peuvent être disposées dans un côté arrière (4) du panneau. L'invention concerne également d'autres panneaux à base de minéraux, tels qu'un panneau de construction, un panneau mural, un panneau de plafond ou un panneau de mobilier. L'invention concerne en outre un procédé de formation de telles rainures (19) dans un panneau à base de minéraux. L'invention concerne également un panneau (1) à base de minéraux comprenant une partie centrale à base de minéraux et une(des) couche(s) inférieure(s) à base de polymère fixée(s) à la partie centrale. Un système de verrouillage du panneau comprend une bande s'étendant horizontalement au-delà d'une partie supérieure du panneau, au moins une partie horizontale de la bande étant entièrement formée dans la(les) couche(s) inférieure(s) à base de polymère.
