Multilayered, rigid material for thermal insulation

摘要

A multilayer material comprises plate (2) of insulating honeycomb material sandwiched between two aluminum- or gold-coated skins (1) of low emissivity. The honeycomb material comprises cells of diameter (in the plane of the plate) that is at least twice their height (perpendicular to the plate). An Independent claim is also included for a method of manufacturing a rigid multilayer material by depositing an adhesive on the end edges of the walls of the cells comprising placing a film of adhesive on the surface of the honeycomb plate; heating the film to burst the cells; thus causing the adhesive to shrink onto the end edges of the cells; and pressing the panels together.
