Elk Premium Building Products, Inc history

1965: Roy E. Campbell and colleagues form Elcor Chemical Corporation in Midland, Texas.

In 1968, backed by two public offerings, the company began construction on a $40 million Texas facility, the Rockhouse Project, to recover sulfur from gypsum using high heat.

By August 1971 Elcor had satisfied its creditors and was ready to continue on as an engineering and construction business.

1972: Chromium Corporation and Elk Roofing Products are acquired.

The first stage of the Elk facility opened in 1978, becoming the first United States plant to apply the Sandy Hill process.

With the oil and gas industry enduring severe difficulties, Elco closed its Midland oil and gas construction business in 1985 and formed the Ortloff Engineers subsidiary to continue offering engineering and consulting services.

With no reason to remain based in Midland, Elcor moved its headquarters to Dallas in 1988.

In 1991 the company was forced to sell its Florida roofing plant, which had been adversely affected by a new housing slump in the state.

In 1994, Elcor approved the construction of a $30 million plant to produce nonwoven materials for use in making fiberglass shingles as well as other construction products.

Not only would the Shafter plant come on line in 1995 at a time when the California economy was expected to be on the upswing, its location cut shipping costs to western states and allowed Elk's Texas plants to better supply the southwestern and midwestern states.

The new Ennis, Texas, facility opened in 1997.

All aspects of Elcor's business made solid progress in fiscal 1998.

In January 1999 Elcor acquired YDK America Inc., a conductive coatings company located in Canton, Georgia.
