摘要:
An infrared-reflective material is applied directly to the bituminous surface of a roofing product to increase the solar heat reflectance of the product, even when deep-tone roofing granules are used to color the product. The infrared-reflective material can be applied as a powder or in a carrier fluid or film, and can be applied along with infrared-reflective roofing granules.
摘要:
A roofing membrane with high solar heat reflectance includes a bituminous base sheet, a tie-layer with a reinforcement material, and a solar heat-reflective upper layer.

A roofing membrane with high solar heat reflectance includes a bituminous base sheet, a tie-layer with a reinforcement material, and a solar heat-reflective upper layer formed from a powder coating filled with a solar heat-reflective 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 colored infrared pigment, light-interference platelet pigment, or a metal oxide.

摘要:
Roofing granules are produced by suspending selected mineral particles in a selected medium to separate the individual particles, uniformly depositing a coating material, and curing the coating material.
摘要:
A roofing article is prepared by applying a thin metal or metal oxide film to a base substrate. The thin film has greater than about 80 percent transmission of incident radiation having a wavelength between 300 nm and 700 nm and greater that about 60 percent reflectance of incident radiation having a wavelength between 700 nm and 2500 nm
摘要:
A security cover for hasp bolts to protect said bolts from attack by drilling, filing or other vandalism by means of an enclosure over the bolt heads. Said hasp bolt cover itself is designed such that the cover is secured from within and is therefore resistant to drilling, prying, blunt force assault or other means of attack.
