Abstract
Provided are construction material granules. In one embodiment, the granules include a core enclosed by a layer comprising a conductive material and a layer comprising a dielectric material. Also provided are related methods of constructing such materials.
Claims24
A coated construction granule, comprising:
- a core;
- a dielectric layer;
- a ceramic layer;
- a single layer disposed between the dielectric layer and the ceramic layer, the single layer being a conductive layer consisting essentially of a metal;
- and
- wherein the coated construction granule reflects greater than about 20% of incident solar radiation,
- wherein the coated construction granule has an emissivity of at least about 75%.
4 more elements
The coated construction granule of 12, wherein the ceramic layer comprises a silica.
A coated construction granule, comprising:
- a core comprising an uncoated particulate material;
- a conductive layer consisting essentially of a metal, the conductive layer directly contacting the core;
- at least one dielectric layer overlying the conductive layer;
- and
- a protective coating overlying the dielectric layer,
- wherein at least one dielectric layer is in direct contact with the conductive layer, and
- wherein the coated construction granule reflects greater than about 20% of incident solar radiation,
- wherein the granule has an emissivity of at least about 75%.
