Abstract

According to some aspects, a thermal insulation material is provided, comprising a first insulation layer having a cellular structure, wherein cells of the cellular structure comprise an inorganic insulator in a powder form and a second insulation layer comprising inorganic fibers. According to some aspects, a fire protection thermal insulation system is provided, comprising a first insulation layer having a cellular structure, wherein cells of the cellular structure comprise an inorganic insulator in a powder form, the first insulation layer on a fire facing side of the thermal insulation system, and a second insulation layer comprising inorganic fibers, the second insulation layer on a non-fire facing side of the thermal insulation system.

First claim

What is claimed is:

1. A thermal insulation material, comprising:
a first insulation layer having a cellular structure, wherein cells of the cellular structure comprise an inorganic insulator in a powder form; and
a second insulation layer comprising inorganic fibers,
wherein a thickness of the second insulation layer is greater than a thickness of the first insulation layer.

2. The thermal insulation material of claim 1 , wherein the thickness of the second insulation layer is at least twice the thickness of the first insulation layer.

3. The thermal insulation material of claim 1 , wherein the cellular structure comprises polyimide and/or polyether ether ketone (PEEK).

4. The thermal insulation material of claim 1 , wherein the inorganic insulator is fumed silica.

5. The thermal insulation material of claim 1 , wherein the powder form is microporous and/or nanoporous.

6. The thermal insulation material of claim 1 , further comprising a reflector layer between the first insulation layer and the second insulation layer.

7. The thermal insulation material of claim 1 , wherein the inorganic fibers include a mineral wool.

8. The thermal insulation material of claim 1 , wherein the thickness of the first insulation layer is less than 1″.

9. The thermal insulation material of claim 1 , wherein a thickness of the thermal insulation material is less than 2″.

10. The thermal insulation material of claim 1 , further comprising a third insulator having a cellular structure, wherein a cell size of the cellular structure of the third insulator is different from a cell size of the cellular structure of the first insulator.

11. The thermal insulation material of claim 10 , wherein the third insulator is polyimide foam.

12. The thermal insulation material of claim 1 , further comprising a layer comprising woven fiberglass and/or woven quartz.

13. A fire protection thermal insulation system comprising:
a first insulation layer having a cellular structure, wherein cells of the cellular structure comprise an inorganic insulator in a powder form, the first insulation layer on a fire facing side of the thermal insulation system; and
a second insulation layer comprising inorganic fibers, the second insulation layer on a non-fire facing side of the thermal insulation system,
wherein a thickness of the second insulation layer is greater than a thickness of the first insulation layer.

14. The fire protection thermal insulation system of claim 13 , wherein the inorganic insulator is fumed silica and the inorganic fibers include a mineral wool.

15. The fire protection thermal insulation system of claim 13 , wherein the thickness of the first insulation layer is less than 1″.

16. The fire protection thermal insulation system of claim 13 , further comprising a layer comprising woven fiberglass and/or woven quartz.

17. The fire protection thermal insulation system of claim 13 , wherein the inorganic fibers include a mineral wool.
