Kaiser Cement and Gypsum...

As the company diversified, with new industrial enterprises leading it to develop new product lines and facilities in new areas, the focus shifted. Permanente, long the foundation of the company, became a cornerstone.

By 1964, Kaiser Gypsum, growing by leaps and bounds, accounted for one-third of the company’s sales. The fourth largest maker of wallboard and other gypsum products in the nation, it built plants in Florida and New Jersey, opening up the Eastern seaboard. No longer a small sibling within the company, the gypsum division had earned its own name on the door and Permanente Cement Company became Kaiser Cement and Gypsum Corporation.
