Abstract: A thermally insulating cloth is provided. The thermally insulating cloth has a layered structure comprising at least three layers, a first and a second outer textile layer providing the outer surfaces of said cloth, and an intermediate layer, wherein said first and said second outer textile layer are laminated to the intermediate layer, said first outer textile layer having an air permeability of less than or equal to 40 cc/sec*5 cm2, said second outer textile layer having air permeability of less than or equal to 40 cc/sec*5 cm2, said intermediate layer comprising a textile fabric comprising aerogel powder, in an amount in a range of 1 to 70% w.

Abstract: A composite thermal insulating material comprises a layer (3, 9) of thermal insulating material between two layers (5, 13) of material selected from cellular glass and cellular concrete material.

Abstract: The invention relates to a panel-shaped, evacuated and thermally insulating molded element which contains pressed and optionally hardened, microporous insulating material, wherein the insulating material is in one or more sheathed and evacuated layers, and the molded element has a surface with a lamellar structure, the lamellae being produced by elongate incisions into the surface and having a depth of 40 to 95% of the thickness of the molded element. The invention also relates to a method of insulation for curved surfaces with thermally insulating material, wherein the molded element is made to fit with the surface with a lamellar structure snugly against the curved surface, is fixed in position, and the vacuum is destroyed in at least one layer.
