1952 Company incorporated[1] 47 percent owned by Johns-Manville Corporation of New York and 53 percent by Cape Asbestos Co to make insulation board for use in ship construction (Marinite was a monolithic asbestos fireproof board which could be made into various shapes). Supplies would be sourced from USA until the factory in Glasgow was ready.
