Ardex Engineered Cements has agreed to acquire the W.W. Henry Co. and all the manufacturing facilities of flooring adhesives, underlayments, and floor care products from Armstrong World Industries. The acquisition brings both companies an offering of new products and capabilities, rather than a merging of two similar companies, Ardex says. The agreement also contains a long-term supply agreement between Ardex and Armstrong to support the latter’s vinyl- and wood-flooring product lines.
