摘要:
An exterior surface covering has a colored outer layer that transmits infrared radiation and an inner layer with a thermochromic pigment that absorbs heat at low temperature and reflects at high temperatures. The outer layer conceals the color change of the thermochromic pigment.
摘要:
An asphalt-based sheet roofing material includes capsules on its upper surface. When struck, as by hailstones, the capsules break to release a film forming fluid that spreads over the surface to heal the damage created by the hailstones.
摘要:
A photovoltaic module includes an encapsulated photovoltaic element and an infrared transmissive decorative overlay simulating conventional roofing.
摘要:
An exterior surface covering has a colored outer layer that transmits infrared radiation and an inner layer with a thermochromic pigment that absorbs heat at low temperature and reflects at high temperatures. The outer layer conceals the color change of the thermochromic pigment.
摘要:
Algae-resistant roofing granules include a mineral core; and an exterior coating including clay, colloidal silica, phosphate, a metal oxide, and a photocatalytic particulate having an average size under 100 nm.
摘要:
Solar-reflective roofing granules having improved solar heat-resistance are formed by coating colored mineral particles with a coating composition including titanium dioxide nanoparticles.
摘要:
The retention of roofing granules on bituminous roofing products is enhanced by providing an adherent material in the interstices between the exterior surface of the roofing granules and the exposed upper surface of the base sheet.
摘要:
An exterior surface covering has a colored outer layer that transmits infrared radiation and an inner layer with a thermochromic pigment that absorbs heat at low temperature and reflects at high temperatures. The outer layer conceals the color change of the thermochromic pigment.
摘要:
Solar-reflective roofing granules having deep-tone colors are formed by coating base mineral particles with a coating composition including an infrared-reflective pigment. Color is provided by a colored infrared pigment, a light-interference platelet pigment, or a metal oxide.
摘要:
Dark colored roofing granules include an inert base particle coated with a composition including a metal silicate, a non-clay latent heat reactant, and a dark colored but solar reflective prigment.
