3. The device of claim 1 or 2, wherein in use in the building partition, the thermal gap is positioned between the first side and the second side of the building partition.

4. The device of any one of the preceding claims, wherein the at least two-part casing is adapted to provide a path for at least one cable through the device from the first side of the partition to the second side of the partition.

5. The device of any one of the preceding claims, wherein the at least two-part casing is adapted to accommodate an intumescent material in the device.

6. The device of any one of the preceding claims, wherein the thermal gap is provided by a body comprising at least one of a gas, a gel or a solid having a lower thermal conductivity than a material of the thermally conductive casing.

7. The device of claim 6, wherein the body comprises at least one of air, a natural polymer or fibre or a synthetic polymer or fibre .

8. The device of claim 6 or 7, wherein the body bridges the first part and the second part.

9. The device of claim 6, 7 or 8, wherein the body comprises an intumescent material.

10. The device of any one of the preceding claims, wherein at least the first part and the second part are aligned end-to-end in the longitudinal direction.

11. The device of any one of claims 1 to 9, wherein the first part is sleeved within the second part.

12. The device of any one of the preceding claims, wherein the first part and the second part each comprise a shell having at least one aperture at each end to provide the path for the cable through the device.

13. The device of any one of the preceding claims, wherein the first part and the second part are open at each end to provide the path for the cable through the device.

14. The device of any one of the preceding claims, wherein the at least two-part casing comprises an upper portion and a lower portion, wherein the upper portion is adapted to engage with the lower portion to form the at least two-part casing.

15. The device of claim 14, wherein the lower portion comprises two elongate substantially U-shaped members positioned end-to-end and separated by the thermal gap.

16. The device of claim 14 or 15, wherein the upper portion comprises two elongate substantially U-shaped members positioned end-to-end and separated by the thermal gap.

17. The device of any one of claims 14 to 16, wherein the upper portion is substantially identical to the lower portion.

18. The device of any one of the preceding claims, further comprising a support within the device for the or each cable.

19. A fire barrier pass-through device for a partition comprising:

at least a two-part thermally conductive casing comprising a first part and a second part and having a longitudinal direction, the first part and the second part offset in the longitudinal direction and separated by a thermal gap that inhibits conduction of thermal energy between the first part and the second part, wherein the at least two-part casing is adapted to be mounted in a partition so that a portion of the first part is adjacent a first side of the partition and a portion of the second part is adjacent a second side of the partition, wherein the at least two-part casing is adapted to provide a path for at least one cable through the device in the longitudinal direction and from the first side of the partition to the second side of the partition, and wherein the at least two-part casing is adapted to accommodate an intumescent material in the device.

20. A fire barrier pass-through device assembly for extending between a first side and a second opposing side of a building partition comprising a fire barrier pass-through device according to any one of the preceding claims.

21. A fire barrier pass-through device assembly for extending between a first side and a second opposing side of a building partition comprising:

at least a two-part thermally conductive casing comprising a first part and a second part separated by a thermal gap that inhibits conduction of thermal energy between the first part and the second part; and an intumescent material positioned within the device.

22. The device assembly of claim 21, wherein the at least two part casing is adapted to be mounted in the partition so that a portion of the first part is adjacent a first side of the partition and a portion of the second part is adjacent a second side of the partition.
