KATY, Texas, May 6, 2019 /PRNewswire/ -- U.S. Silica
Holdings, Inc. (NYSE: SLCA) announced today that the United States
Patent and Trademark Office has issued US Patent 10253493, entitled
"Particulates having high total solar reflectance." The patent
covers solar reflective particulate composition used for U.S.
Silica's White Armor® Cool Roof Granules. White Armor durable white
granules reflect the sun's heat instead of absorbing heat and
transferring it to the building below. Customer results indicate
that at least 70% of solar heat is reflected with White Armor Cool
Roof Granules featuring the patented particulate composition.
"We're very excited about our unique White Armor roofing product
and the new patent on the solar reflective technology," said J.P.
Blanchard, senior vice president,
U.S. Silica. "This is another example of U.S. Silica's
commitment to product innovation and new products," he said,
adding, "White Armor reflects the sun's energy, benefitting the
environment through lower energy consumption and generates
substantial overall savings because there is less need for air
conditioning," he added. "The market for cool roofs is growing
internationally and here in the U.S., as more cool roof guidelines
and regulations are put in place," said Blanchard.
White Armor is the highest solar reflecting granular product
solution available today for bitumen (asphalt) roofing. The
granules are white throughout, offering maximum reflectivity. U.S.
Silica plans to manufacture the White Armor Cool Roof Granule
product at its newest industrial manufacturing plant in
Millen, GA, purchased in
December 2018. The Millen plant has been retooled to efficiently
produce the White Armor product. White Armor granules are applied
to bitumen (asphalt) rolls and mineral cap top sheets to produce a
multi-layered roof system that reflects heat, repels water and is
long lasting. For more information on U.S. Silica's White
