Abstract: An insulation material comprising an insulation material substrate with a substrate surface, the insulation material further having a plurality of protrusions affixed to or integrated into substrate surface, each protrusion having an abutting surface distal to a protrusion base and a protrusion body connecting the abutting surface and the protrusion base, and each protrusion having an abutting surface height of at least 2 mm, wherein the abutting surface height is the shortest distance between the plane of the abutting surface and the plane of the protrusion base.

Abstract: A method for the continuous production of a cellular ceramic plate having asymmetric cells comprising thermally treating ceramic particles and a blowing agent in a foaming furnace while conveying said ceramic particles and said blowing agent at a first speed thereby forming a cellular ceramic plate, and annealing said cellular ceramic plate in an annealing lehr by cooling it down while conveying it at a second speed, larger than said first speed, thereby stretching and cooling said cellular ceramic plate.
