Abstract

A roof tile comprising a ceramic body and a reinforcing element attached to a lower surface of the ceramic body.

Claims (20)

1. A roof tile comprising a ceramic body, a reinforcing element attached to a lower surface of the ceramic body, and a support layer attached below the reinforcing element, wherein the reinforcing element consists of a resin, wherein the resin covers 80 percent or more of the lower surface of the ceramic body, wherein the support layer comprises a rigid polymer with embedded fiberglass, wherein the support layer comprises coupling parts adapted to provide for attachment of the roof tile to a roof framework, and wherein the coupling parts provide for a click-type or snap-type coupling.

2. The roof tile according to claim 1 , wherein the resin comprises a viscosity less than 1,000 mPas at 20° C. when the resin is uncured.

3. The roof tile according to claim 1 , wherein said resin comprises a tensile strength between 50 and 90 MPa after curing.

4. The roof tile according to claim 1 , wherein said resin comprises a hardness above 50 Shore D after curing.

5. The roof tile according to claim 1 , wherein said resin is provided, when the resin is uncured, in an amount above 50 g/sqm.

6. The roof tile according to claim 1 , wherein said resin comprises epoxy, polyurethane, acrylic and/or polyester resin.

7. The roof tile according to claim 1 , wherein the support layer is made of a solid polymer composite (SPC).

8. The roof tile according to claim 1 , wherein the roof tile comprises at least an attachment hole provided in the support layer.

9. The roof tile according to claim 8 , wherein the coupling parts comprise the attachment hole.

10. The roof tile according to claim 1 , wherein the support layer comprises a thickness below 4 mm.

11. The roof tile according to claim 1 , wherein the coupling parts are adapted to provide a mechanical coupling with the coupling parts of an adjacent roof tile.

12. The roof tile according to claim 11 , wherein the coupling parts are configured to prevent vertical movement between the roof tile and said adjacent roof tile.

13. The roof tile according to claim 11 , wherein the coupling parts are adapted to provide the mechanical coupling of the roof tile to the adjacent roof tile by movement of the roof tile relative to the adjacent roof tile.

14. The roof tile according to claim 1 , comprising at least an attachment hole provided in the ceramic body.

15. The roof tile according to claim 1 , wherein the ceramic body comprises a thickness below 8 mm, preferably below 6 mm.

16. The roof tile according to claim 1 , wherein the roof tile comprises a weight below 20 kg/sqm.

17. The roof tile according to claim 1 , wherein the roof tile comprises a rectangular shape and a top décor imitating a plurality of roof tiles.

18. The roof tile according to claim 1 , wherein the coupling parts are formed in the support layer.

19. The roof tile according to claim 1 , wherein the coupling parts are at least substantially formed from the rigid polymer embedded with fiberglass.

20. The roof tile according to claim 1 , wherein the resin covers about 100 percent of the lower surface of the ceramic body.
