Abstract
A building panel, such as a floor panel, a wall panel, or a furniture component, including a multi-layered substrate having a back side layer with lignocellulosic particles and a binder, an intermediate layer with lignocellulosic particles and a binder, arranged on the back side layer, a front side layer with lignocellulosic particles and a binder, arranged on the intermediate layer. The building panel further includes a front cork layer attached to the front side layer of the multi-layered substrate. Also, a method of producing a building panel.
Claims29
A method of producing a building panel, comprising:
- applying a back side layer comprising a first mixture of at least lignocellulosic particles and a binder,
- applying an intermediate layer comprising a second mixture of at least lignocellulosic particles and a binder, on the back side layer,
- applying a front side layer comprising a third mixture of at least lignocellulosic particles and a binder, on the intermediate layer,
- applying a front cork layer by applying cork particles on the front side layer prior to applying pressure and heat, and
- applying pressure and heat to the back side layer, the intermediate layer, the front side layer, and the front cork layer, thereby forming the building panel.
A building panel comprising
- a multi-layered substrate comprising
- a back side layer comprising lignocellulosic particles and a binder,
- an intermediate layer comprising lignocellulosic particles and a binder, arranged on the back side layer,
- a front side layer comprising lignocellulosic particles and a binder, arranged on the intermediate layer, and
- a front cork layer comprising cork particles, arranged on the front side layer, wherein a surface of the front cork layer opposite the front side layer is substantially free from added binder.
