Rock Wool Cement was a cement from The Ruberoid Co.1,2 In its 1989 filing with the U.S. Environmental Protection Agency under the Asbestos Information Act, made for itself and The Ruberoid Co., GAF said that "little is known about this product," which was "apparently available from Ruberoid in the late 1940's and early 1950's."1 It consisted of a mixture of rock wool and chrysotile asbestos and had a temperature limit of 1500 degrees F.1
A 1990 EPA notice that published what GAF reported repeats that account: available in the late 1940's and early 1950's, a mixture of rock wool and chrysotile asbestos, with a temperature limit of 1,500 °F.2
