Perthshire-based entrepreneur Simon Howie has sold 100% stakes in Mermaid Panels and Shore Laminates, manufacturers of shower walls and wall panel systems, to Wilsonart Engineered Surfaces, a global manufacturer and distributor of engineered surfaces headquartered in Austin, Texas. Wilsonart has bought the business as a bolt-on to its other UK operations, Bushboard and Wilsonart UK, which make laminate-faced products such as kitchen worktops and wall panelling.
