Rollboard was an asbestos paper product from The Ruberoid Co. and GAF, made of plies of asbestos paper bonded together without glue.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 it came in thicknesses from 1/16 to 1/8 of an inch and had a temperature limit of 250 degrees F.2 A 1990 EPA notice that published what GAF reported gives the same description and limit.1
The notice dates GAF's asbestos paper and millboard products as a group: produced by Ruberoid from 1928 to 1967, by General Aniline & Film Corporation in 1967, and by GAF Corporation from 1968 to 1981.1 The 1989 filing lists rollboard formulas from about December 1938, for a regular 1/8" commercial rollboard, and from 1970 and 1971 to 1977.2
