Owens Corning reported consolidated net sales of $5.4 billion in 2015, compared to net sales of $5.3 billion in 2014.

Fourth quarter 2015 adjusted earnings were $79 million compared with $55 million during the same period one year ago. The company reported net earnings of $109 million in the fourth quarter of 2015, compared with net earnings of $33 million in 2014.

Full-year 2015 adjusted earnings were $304 million compared to adjusted earnings of $208 million in 2014. Net earnings in 2015 were $330 million compared to net earnings of $226 million last year.

“Owens Corning delivered an outstanding year with $550 million of adjusted EBIT,” said chairman and CEO Mike Thaman. “Strong operational and commercial execution drove significant earnings growth in all three of our businesses, resulting in the best year of earnings growth in the history of our company.”

Owens Corning expects all three businesses to grow earnings in 2016 based on consensus expectations for U.S. housing starts and moderate global growth.

In Composites, the company expects continued growth in the glass fiber market driven by moderate global industrial production growth. In Roofing, the company anticipates modest market growth in 2016, primarily driven by growth in new construction markets. Weaker oil prices should provide opportunity for further asphalt cost deflation. In Insulation, the company expects revenue growth will be slightly weaker than the growth experienced in 2015. While Owens Corning expects margin expansion, the magnitude of the improvement could fall below that experienced in 2015 and is dependent upon the progression of pricing and volume in the U.S. residential new construction market.
