It has 17 gypsum board plants in the US and presents itself as a fully integrated building products manufacturer.[1] It is a private company, incorporated as New NGC, Inc. in 1993 after previously filing for Chapter 11 bankruptcy in 1990.[2] In 1995, Clemmie Spangler took over National Gypsum for $1.2 billion, through Delcor Inc., a private investment company controlled by him.[3] Spangler had been chairman of National Gypsum and owned 20% of the company, and his family went on to own the whole company.[3][4]
