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:
A roof covering material is provided, as well as its method of manufacture, wherein a substrate, preferably of a fibrous material is provided, with a bituminous material, preferably asphalt coating, on opposite surfaces thereof, with granules being applied to an upper surface thereof and at least partially embedded in the bituminous material, and with a discontinuous top layer applied to the granule/bituminous material. The discontinuous top layer is preferably a polymeric material, and openings are provided therein, for passage of fluids therethrough, to avoid moisture, volatiles, and other fluid materials from being trapped beneath the top layer. Various techniques for application of the various materials, and for chemical treatment, are likewise provided.
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:
A roofing product has a substrate having a binder layer and roofing granules on a majority of the binder layer, such that an exposed portion of the binder layer does not have the roofing granules. In addition, reflective particles may be located on the exposed portion of the binder layer. The reflective particles are smaller in size than the roofing granules, and the reflective particles have a solar reflectance of greater than 40%.
