Honeycomb transparent insulation with improved insulating ability
First Claim
1. In a glazing system comprising a honeycomb transparent insulation sandwiched between glass and comprising an array of open-ended cell whose axes are oriented normal to the plane of the insulation, the improvement wherein said cells have walls comprising a composite material consisting essentially of inorganic particles having strong absorption/emissivity in the thermal infrared wavelength regions and negligible absorption in the visible (400 nm to 700 nm regions) dispersed in a plastic resin binder, said inorganic particles and said plastic resin binder have substantially matching refractive indices for visible light, and said inorganic particles have a size selected from the group consisting of a first range less than 200 nm and a second range between 1 and 30 μ
- m, whereby said honeycomb insulation is substantially clear.

Abstract
An inorganic particulate, having strong absorption in the thermal infrared region of the radiative spectrum and low absorption in the solar or visible portion of the radiative spectrum, is combined with a plastic resin, to create a composite material. This composite is used in whole or in part to manufacture a honeycomb transparent insulation material, or is applied as a coating to a honeycomb transparent insulation material. The resulting honeycomb transparent insulation can have similar visible or solar light transmittance, and will have improved thermal radiant suppression relative to an identical honeycomb made of plastic resin only.

11. A method of making a glazing system comprising:
-
providing a plastic resin and plurality of inorganic particles, said plastic resin and said inorganic particles having substantially matching refractive indices, said inorganic particles having strong absorption/emissivity in the thermal infrared wavelength regions and negligible absorption in the visible (400 nm to 700 nm regions) and said inorganic particles having a size selected from the group consisting of a first range less than 200 nm and a second range between 1 and 30 μ
m;
blending said inorganic particles with said plastic resin to form a substantially clear composite film; and
manufactureing from said film a honeycomb insulation sheet comprising an array of radiation absorbing open-ended cells whose axes are oriented normal to the plane of the insulation; and
sandwiching said honeycomb sheet between glass. - View Dependent Claims (12, 13, 14)
