Calsilite-Hi (GAF)

Calsilite-Hi was a high-temperature thermal insulation developed by The Ruberoid Co.1 In September 1960, Asbestos, the industry's trade journal, carried Ruberoid's announcement of it as "a new thermal insulation that withstands soaking heat up to 1800°F indefinitely" and that also served as an industrial fireproofing material.1 Ruberoid described it there as "a calcium silicate compound combined with asbestos fibres and other materials."1

It was offered in "half-sectional, three segmental and block form," for insulating piping and equipment in all types of plants, and for fireproofing walls, partitions and ceilings in refineries and chemical processing plants.1 In 1989, in its filing with the U.S. Environmental Protection Agency under the Asbestos Information Act, made for itself and The Ruberoid Co., GAF said Calsilite-Hi was developed in or around 1960 and could withstand temperatures up to 1800° F.2
