Floor panel with sealing means
Floor panels and floor elements therefore are made of sheet-shaped cores which are formed with sealing means for preventing or counteracting changes in the properties of the floor panels caused by moisture.
1. A floor panel, comprising a body having a core, wherein in said floor panel at least two opposite parallel joint edge portions are provided with connectors for mechanical joining of the floor panel in the horizontal direction with similar floor panels, said connectors having active locking surfaces for cooperation with corresponding active locking surfaces of adjacent floor panels after the floor panel has been joined therewith, the core having an upper surface layer, wherein a first material seal of a resilient surface layer covers the upper surface layer of the core and a second material seal of an impregnating material penetrates through the upper surface layer of the core and into the core from the upper surface layer towards a central portion of the core.
2. The floor panel as claimed in claim 1 , wherein the core is of a solid wood, plywood, particle board, flake board, fiberboard, medium density fiberboard, or high density fiberboard.
3. The floor panel as claimed in claim 2 , wherein a groove is provided in an upper edge portion of the floorboard, where one of the connectors is to be formed, said groove being provided with an elastically deformable material and/or an impregnation agent.
4. The floor panel as claimed in claim 1 , wherein said connectors are made for joining of a floor panel with a previously installed floor panel by inward angling and/or by snapping-in to a locked position.
5. The floor panel as claimed in claim 4 , wherein said connectors cooperate for mechanical joining of the floor panel in the vertical and/or horizontal direction.
6. The floor panel as claimed in claim 1 , wherein the resilient surface layer covers the entire upper surface layer of the core.
7. The floor panel as claimed in claim 1 , wherein the first material seal is adapted to seal adjacent joint edges when the floor panel has been joined with an adjacent floor panel.
8. The floor panel as claimed in claim 1 , wherein the second material seal is underneath a top surface layer of the floor panel.
9. The floor panel as claimed in claim 1 , wherein the second material seal is immediately underneath a top surface layer of the floor panel.
10. The floor panel as claimed in claim 1 , wherein the highest concentration of the second material seal penetrating into the core is immediately underneath a top surface layer of the floor panel.
11. The floor panel as claimed in claim 1 , wherein the depth of the second material seal penetrating into the core is 0.1-0.3 times the thickness of the floor panel.
12. The floor panel as claimed in claim 1 , wherein a material seal also penetrates into the core from a lower surface layer of the core.
13. A floor panel, comprising a body having a core, wherein in said floor panel at least two opposite parallel joint edge portions are provided with connectors for mechanical joining of the floor panel in the horizontal direction with similar floor panels, said connectors having active locking surfaces for cooperation with corresponding active locking surfaces of adjacent floor panels after the floor panel has been joined therewith, the core having an upper surface layer, wherein a material seal of a resilient surface layer covers the upper surface layer of the core, the material seal is of plastic or linoleum, and a surface layer is provided over the plastic or the linoleum and directly contacts the plastic or the linoleum, the surface layer comprising elastic material.
14. The floor panel as claimed in claim 13 , wherein the active locking surfaces are provided in the core of the floor panel.
15. The floor panel as claimed in claim 13 , wherein the connectors are configured for joining the floor panel with a previously installed floor panel by inward angling.
16. The floor panel as claimed in claim 13 , wherein the plastic or the linoleum directly contacts the core.
17. A floor panel, comprising a body having a core, wherein in said floor panel at least two opposite parallel joint edge portions are provided with connectors for mechanical joining of the floor panel in the horizontal direction with similar floor panels, said connectors having active locking surfaces for cooperation with corresponding active locking surfaces of adjacent floor panels after the floor panel has been joined therewith, the core having an upper surface layer, wherein a material seal of a resilient surface layer covers the upper surface layer of the core, the material seal further comprises a surface layer of transparent wear layer of a plastic material, an intermediate decorative layer of a plastic film and reinforcement layer of an elastic material, and the transparent wear layer is harder than the reinforcement layer, and wherein the material seal further comprises a joint seal, the joint seal comprising a protrusion and a recess.
18. The floor panel as claimed in claim 17 , wherein the joint seals are provided in the reinforcement layer.
19. A floor panel, comprising a body having a core, and comprising a decorative layer, wherein in said floor panel at least two opposite parallel joint edge portions are provided with connectors for mechanical joining of the floor panel in the horizontal direction with similar floor panels, said connectors having active locking surfaces for cooperation with corresponding active locking surfaces of adjacent floor panels after the floor panel has been joined therewith, the core having an upper surface layer, wherein a material seal of a resilient surface layer covers the upper surface layer of the core, the material seal is of plastic or linoleum, and a surface layer is provided over the plastic or the linoleum, the surface layer comprising elastic material.
20. The floor panel as claimed in claim 19 , wherein the plastic or the linoleum directly contacts the core.
21. A floor panel, comprising a body having a core, wherein in said floor panel at least two opposite parallel joint edge portions are provided with connectors for mechanical joining of the floor panel in the horizontal direction with similar floor panels, said connectors having active locking surfaces for cooperation with corresponding active locking surfaces of adjacent floor panels after the floor panel has been joined therewith, the core having an upper surface layer, wherein a material seal of a resilient surface layer is disposed above the upper surface layer of the core, the material seal is of plastic or linoleum, and a surface layer is provided over the plastic or the linoleum and directly contacts the plastic or the linoleum, the surface layer comprising elastic material.
22. A floor panel, comprising a body having a core, and comprising a decorative layer, wherein in said floor panel at least two opposite parallel joint edge portions are provided with connectors for mechanical joining of the floor panel in the horizontal direction with similar floor panels, said connectors having active locking surfaces for cooperation with corresponding active locking surfaces of adjacent floor panels after the floor panel has been joined therewith, the core having an upper surface layer, wherein a material seal of a resilient surface layer is disposed above the upper surface layer of the core, the material seal is of plastic or linoleum, and a surface layer is provided over the plastic or the linoleum, the surface layer comprising elastic material.
