Abstract
An insulation useful in the field of building materials, refrigeration, cryogenics, and shipping. The insulation has reduced radiative heat transfer by applying coating to the insulation material in order to alter the emissivity, including the infrared electromagnetic spectrum.
Claims20
A material comprising:
- an insulating material;
- a low-emissivity coating on a surface of said insulating material;
- wherein said low-emissivity coating has a thermal conductivity of less than or equal to 0.6 W/m-K and an emissivity less than or equal to 0.5 of electromagnetic radiation having a wavelength selected from the range of 1 mm to 2.5 μm.
A method comprising:
- providing an insulating material;
- coating a surface of said insulating material with a low-emissivity coating;
- wherein said low-emissivity coating has a thermal conductivity of less than or equal to 0.6 W/m-K and an emissivity less than or equal to 0.5 of electromagnetic radiation having a wavelength selected from the range of 1 mm to 0.2 μm.
