Flat Transite (Johns-Manville)

Flat Transite was a Johns-Manville asbestos-cement board, which J-M's employee magazine called "flat Transite asbestos wood" in 1928.1,2,3 A 1990 EPA notice that published what Manville reported says corrugated and flat Transite and Transite acoustical panel were produced from 1930 to 1982.2 An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, gives Flat Transite, listed as board, as made from 1930 to 1981, the list's own year.1 J-M's employee magazine shows a Cleveland salesman already taking orders for it from laundries in September 1928.3

For the asbestos content, Manville's 1990 report gives one range for corrugated and flat Transite and the acoustical panel together: 25 to 35 percent asbestos fiber, with 40 to 45 percent portland cement and 25 to 30 percent silica.2

J-M's employee magazines report a wide range of uses: table tops and flat iron stands in laundries in 1928, a trampled-and-broken "flagstone walk" of one-eighth inch sheets for the stage production "Miracle" in Milwaukee in 1929, and the fume hoods and ventilating ducts of a new chemistry annex at the University of Illinois in 1930.3,4,5 In 1938 J-M offered it, like Flexboard, as the outer veneer of insulated curtain walls for factory buildings.6 In 1945 J-M listed Flat Transite among the products it had supplied to the Manhattan Project.7 In 1966 J-M's Nashua plant was making flat Transite sheets for customers who made defense and space products, and a 1969 J-M survey names a "Flat Transite Saw Operator" station at its Pittsburg plant.8,9
