Owens Corning cuts FY14 adjusted EBIT to $416M from $500M Cuts roofing volumes in 1H14 to be 20% lower than 1H13 volumes. The company expects to recover a portion of this volume shortfall in the second half of the year. However, continued weakness in the second quarter has introduced further uncertainty in the full-year financial outlook for the company's roofing business. The company continues to see improvement in the year-over-year performance of both its insulation and composites businesses. Earnings growth in these two businesses is expected to more than offset the weaker financial performance in the roofing business year over year.
