Wall, floor and/or ceiling lining panel and method for their production

摘要

The panel (1) has a tongue profile (3) and a groove profile provided on two neighboring outer corners. A tongue profile recess (11) and a groove profile recess have a rectangular cross section perpendicular to a plane of the panel. The profiles are formed from a timber product e.g. medium density fiberboard or high density fiberboard, and are mechanically locked with each other. A recess is milled on the panel adjacent to an edge (14) of the outer corners, where a contour of the recess is sectionally extended longer than a contour of the profiles of the outer corners. An independent claim is also included for a method for production of a panel for a wall lining, a floor lining and a ceiling lining.
