NEW YORK, March 29 (Reuters) - Building materials company Armstrong Holdings Inc. on Thursday named former Harsco Corp. executive Leonard Campanaro as its senior vice president and chief financial officer.

Campanaro succeeds E. Follin Smith, who resigned effective March 30 to pursue other professional opportunities.

Campanaro, who was president and chief operating officer at industrial products company Harsco, will start at Armstrong on April 2, Armstrong said in a press release.

Earlier on Thursday Armstrong reported a net loss of $100.3 million, or $2.48 per share, for the fourth quarter, versus a loss of $178.5 million, or $4.46 per share, a year ago. It said results were hurt by high raw material and energy costs and weaker sales.
