RPM International Inc. has acquired Ontario, Canada-based Nudura Corp., a manufacturer and distributor of insulated concrete forms. Terms of the transaction were not disclosed. Nudura, with annual net sales in excess of $40 million, has three strategically located manufacturing plants and an extensive network of 260 locally based professional distributors in key North American markets. Its patented products are sold to design professionals, architects and contractors for residential and commercial applications. They are used to construct homes, schools, medical and commercial facilities, and other buildings that can benefit from the insulative and structural properties of ICF construction. Nudura will operate within the RPM Specialty Products Group as a stand-alone operating unit of RPM’s Dryvit business, which manufactures exterior insulation and finish systems and NewBrick, a lightweight, energy efficient brick product. “Nudura is an excellent strategic fit that offers several key competitive advantages for Dryvit. Its product line will complement and expand Dryvit’s existing product offering, allowing for enhanced cross-selling opportunities,” said Frank C. Sullivan, chairman and CEO of RPM, in a statement. “At the same time, Nudura’s manufacturing footprint will be leveraged for efficiencies in the manufacturing of Dryvit’s NewBrick product, as well as products of other companies within our Specialty Products Group.” Sullivan has been involved in hundreds of acquisitions.
