Abstract

The roll-up floor heating comprises an insulating layer, a heating element and a cladding. The insulating layer is intended for laying on a floor and the heating element extends between the cladding and the insulating layer. The cladding is intended to support a floor covering and comprises a force distribution layer for transmitting a force which is exerted on the cladding in a distributed manner to the insulating layer. In as far as (a part of) the heating element is at the location or in the vicinity of the exerted force, the load which will be exerted on it will be lower than the original load, due to the force being transmitted in a distributed manner. This lowers the risk of the heating element being damaged.

Claims (35)

1. Roll-up heating for a floor, or wall, comprising

an insulating layer, a heating element and a cladding, in which the insulating layer is adapted for laying on a floor and the heating element extends between the cladding and the insulating layer,

wherein the cladding is adapted to support a floor covering and comprises a force distribution layer for transmitting a force which is exerted on the cladding in a distributed manner to the insulating layer,

and wherein the force distribution layer comprises a first and a second sub-layer, in which the first sub-layer has a higher modulus of elasticity than the second sub-layer and the second sub-layer faces the insulating layer.

2. Roll-up heating for a floor, or wall, according to claim 1 , in which the thickness of the force distribution layer is at least 2 mm.

3. Roll-up heating for a floor, or wall, according to claim 1 , in which the insulating layer comprises a plastic foam.

4. Roll-up heating for a floor, or wall, according to claim 1 , in which a heat-diffusing layer is provided between the cladding and the insulating layer.

5. Roll-up heating for a floor, or wall, according to claim 1 , in which the heating element comprises an electrical resistance cable, which comprises a first resistance wire.

6. Roll-up heating for a floor, or wall, according to claim 5 , in which the electrical resistance cable follows a meandering looping path with a distance between the loops at most 6 cm.

7. Roll-up heating for a floor, or wall, according to claim 5 , in which the thickness of the force distribution layer is equal to at least half the diameter of the electrical resistance cable.

8. Roll-up heating for a floor, or wall, according to claim 5 , in which the force distribution layer is compressible in such a manner that the electrical resistance cable is at least partially accommodated therein.

9. Roll-up heating for a floor, or wall, comprising

an insulating layer, a heating element and a cladding,

in which the insulating layer is adapted for laying on a floor and the heating element extends between the cladding and the insulating layer,

the cladding is adapted to support a floor covering, and the cladding comprises a force distribution layer for transmitting a force which is exerted on the cladding in a distributed manner to the insulating layer,

and wherein the force distribution layer comprises a first and a second sub-layer, in which the first sub-layer has a higher modulus of elasticity than the second sub-layer and the second sub-layer faces the insulating layer,

the heating element comprises an electrical resistance cable, which comprises a first resistance wire,

wherein the electrical resistance cable furthermore comprises an electrically insulating sleeve extending around the first resistance wire and an earthing sheath extending around the insulating sleeve, the earthing sheath comprising an electrically conductive foil.

10. Roll-up heating for a floor, or wall, according to claim 9 , in which the electrically conductive foil runs substantially parallel to the insulating sleeve and is folded around it.

11. Roll-up heating for a floor, or wall, according to claim 9 , in which the electrically conductive foil is helically wound around the insulating sleeve in strip form.

12. Roll-up heating for a floor, or wall, according to claim 1 , in which the insulating layer comprises a sound-absorbing material which results in a noise reduction of at least 10 dB.

13. Roll-up heating for a floor, or wall, according to claim 1 , in which the compressibility of the roll-up floor heating is low and wherein the floor covering comprises floor tiles.

14. Roll-up heating for a floor, or wall, according to claim 1 , wherein the floor covering comprises a wooden floor glued onto the cladding and wherein the force distribution layer is elastic to absorb the shrinkage and expansion of the wooden floor.

15. Roll-up heating for a floor, or wall, according to claim 1 , provided with a socket for interconnecting multiple strips of heating for a floor, or wall, or connecting the roll-up heating for a floor, or wall to an electric power supply.

16. Roll-up heating for a floor, or wall, according to claim 7 , in which the thickness of the force distribution layer is equal to at least the entire diameter of the electrical resistance cable.

17. Roll-up heating for a floor, or wall, according to claim 5 , in which the thickness of the force distribution layer is equal to at least twice the diameter of the electrical resistance cable.

18. Roll-up heating for a floor, or wall, according to claim 9 , wherein the electrically conductive foil is aluminum foil.

19. Roll-up heating for a floor, or wall, comprising

an insulating layer, a heating element and a cladding,

in which the insulating layer is adapted for laying on a floor and the heating element extends between the cladding and the insulating layer,

wherein the cladding is adapted to support a floor covering, and wherein the cladding comprises a force distribution layer for transmitting a force which is exerted on the cladding in a distributed manner to the insulating layer;

wherein the force distribution layer comprises a first and a second sub-layer, in which the first sub-layer has a higher modulus of elasticity than the second sub-layer and the second sub-layer faces the insulating layer;

wherein the thickness of the force distribution layer is at least 2 mm;

wherein the heating element comprises an electrical resistance cable, which comprises a first resistance wire; and

wherein the electrical resistance cable follows a meandering looping path with distance between the loops at most 6 cm.
