LT (Armstrong Cork)

LT was a cork pipe covering made by Armstrong Cork Company, with an outer covering of aluminum foil and asbestos paper.1 In sworn answers given in two lawsuits in April 1970, Armstrong said: "We manufactured LT pipe covering for several years until 1957."1,2 The answers say it "consisted of cork board with an aluminum foil and asbestos paper laminate covering"; the asbestos was in that covering, not in the cork.1,2

A 1990 EPA notice that published what Armstrong World Industries reported names it LT Cork Covering, a low temperature thermal system cork insulation, and gives different years: it says Armstrong produced it with asbestos from 1956 to 1959.3 The notice describes it as "a wrap-around insulation consisting of wedge-shaped cork segments cemented to a laminate consisting of aluminum foil and asbestos paper."3 An insurance company's 1981 list of asbestos products, compiled from other companies' answers in lawsuits, gives the same years, listing LT pipe covering under Armstrong Cork as made from 1956 to 1959, with "ASB PAPER OVER CORK" in its note column.4
