A fire gutted a 9,000-sq-ft building at the Canadian head office and manufacturing and distribution center of the Henry Co., a manufacturer of commercial and residential foundation coatings, roofing products, caulks, adhesives, driveway sealers, and other building products marketed under the Building Envelope Systems® trademark.
