Abstract
A building panel with a surface layer (1) including a wood veneer, a wood fibre based core (2) and a sub-layer (3) between the surface layer (1) and the core (2). The sub-layer (3) includes wood fibres (4) and a binder (5). The surface layer (1) has surface portions (6) including material from the sub-layer (3). The surface portions (6) including material from the sub-layer (3) extend into the wood veneer.
Claims22
A building panel comprising:
- a surface layer comprising a wood veneer, the wood veneer comprising porous portions and non-porous portions,
- a wood fibre based core, and
- a sub-layer arranged between the surface layer and the wood fibre based core, the sub-layer being a separate discrete layer from the core,
- wherein the sub-layer comprises wood fibres and a binder,
- wherein the surface layer has surface portions comprising material from the sub-layer extending into the wood veneer, and
- wherein the surface layer comprising embossed portions and protrusions, wherein the binder of the sub-layer bonds the porous portions of the wood veneer in a compressed position to form the embossed portions, and wherein the binder does not bond the non-porous portions of the wood veneer in the compressed position so that the non-porous portions of the wood veneer form the protrusions.

A building panel comprising:
- a surface layer comprising a wood veneer, the wood veneer comprising porous portions and non-porous portions,
- a wood fibre based core, and
- a sub-layer arranged between the surface layer and the wood fibre based core,
- wherein the sub-layer comprises wood fibres, a binder and colour pigments and/or a colorant,
- wherein the surface layer has surface portions comprising material from the sub-layer extending into the wood veneer, and
- wherein the surface layer comprising embossed portions and protrusions, wherein the binder of the sub-layer bonds the porous portions of the wood veneer in a compressed position to form the embossed portions, and wherein the non-porous portions of the wood veneer form the protrusions by containing less of the binder than the porous portions.

A building panel comprising:
- a surface layer comprising a wood veneer, the wood veneer comprising porous portions and non-porous portions,
- a wood fibre based core, and
- a sub-layer arranged between the surface layer and the wood fibre based core,
- wherein the sub-layer comprises wood fibres, a binder and wear resistant particles,
- wherein the surface layer has surface portions comprising material from the sub-layer extending into the wood veneer,
- wherein the binder is between 40-60 wt-% of the sub-layer, and
- wherein the surface layer comprising embossed portions and protrusions, wherein the binder of the sub-layer bonds the porous portions of the wood veneer in a compressed position to form the embossed portions, and wherein the binder does not bond the non-porous portions of the wood veneer in the compressed position so that the non-porous portions of the wood veneer form the protrusions.
4 more elements
A building panel comprising:
- a surface layer comprising a wood veneer, the wood veneer comprising relatively high-density portions and relatively low-density portions,
- a wood fibre based core, and
- a sub-layer arranged between the surface layer and the wood fibre based core, the sub-layer being a separate discrete layer from the core,
- wherein the sub-layer comprises wood fibres and a binder,
- wherein the surface layer has surface portions comprising material from the sub-layer extending into the wood veneer, and
- wherein the surface layer comprises embossed portions and protrusions, wherein the binder of the sub-layer bonds the relatively low-density portions of the wood veneer in a compressed position to form the embossed portions, and wherein the binder does not bond the relatively high-density portions of the wood veneer in the compressed position so that the relatively high-density portions of the wood veneer form the protrusions.
