Westlake Consolidates Brands, Shuts Cologne PVC Plant Amid Market Shift
Westlake Royal Building Products has merged its US Tile® and Newpoint™ roofing brands into a single name and added standing‑seam roofing assets, broadening its U.S. roofing footprint. At the same time the company is closing its Cologne PVC plant because the European market remains weak. Analysts have cut their price targets, reflecting a more cautious outlook on cash‑flow recovery.
