Abstract

Thermal insulation body comprising a thermally insulating core having holes filled with a capillary-active material, wherein the thermally insulating core is capillary-inactive and the capillary-active material in the holes comprises capillary-active wicks.

First claim

1 - 14 . (canceled)

15 . A thermal insulation body, comprising:
a thermally insulating core having holes filled with a capillary-active material, wherein the thermally insulating core is capillary-inactive and the capillary-active material in the holes comprises capillary-active wicks.

16 . The thermal insulation body according to claim 15 ,
wherein the holes have a diameter of 100 to 6000 μm.

17 . The thermal insulation body according to claim 15 ,
wherein the capillary-active wicks have a density per unit area of 10 to 10 000 wicks/m 2 .

18 . The thermal insulation body according to claim 15 ,
wherein the cross-sectional area of the capillary-active wicks is from 0.001 to 1 mm 2 .

19 . The thermal insulation body according to claim 15 ,
wherein the capillary-active wicks comprise a material selected from the group consisting of yarns, twines, threads, textured spun threads, filaments and cords.

20 . The thermal insulation body according to claim 15 ,
wherein the material of the capillary-active wicks is selected from the group consisting of basalt, silica, E glass, C glass and glass.

21 . The thermal insulation body according to claim 15 ,
wherein the capillary-active wicks project out of the thermal insulation body or end flush with the surface of the thermal insulation body.

22 . The thermal insulation body according to claim 15 ,
wherein the thermally insulating, capillary-inactive core is a thermal insulation sheet, a thermal insulation mat or a thermal insulation bed.

23 . The thermal insulation body according to claim 15 ,
wherein the thickness of the thermally insulating, capillary-inactive core is 3 to 150 mm.

24 . The thermal insulation body according to claim 15 ,
wherein the thermally insulating, capillary-inactive core has a thermal conductivity of less than 0.025 W/(mK).

25 . The thermal insulation body according to claim 15 ,
wherein the thermally insulating, capillary-inactive core contains hydrophobic fumed silica.

26 . The thermal insulation body according to claim 15 ,
which comprises at least one capillary-active outer layer on one or both sides of the thermally insulating, capillary-inactive core, with the capillary-active wicks ending within or protruding from the capillary-active outer layer.

27 . The thermal insulation body according to claim 15 ,
wherein the material of the capillary-active outer layer is selected from the group consisting of a capillary-active textile fabric, a capillary-active open-pore foam and/or a capillary-active porous layer.

28 . The thermal insulation body according to claim 15 ,
which has a layer that acts as a vapor barrier or vapor retarder between the thermally insulating, capillary-inactive core and the capillary-active outer layer, through which the capillary-active wicks are conducted.
