The Royal visit marked a year since the first SterlingOSB Zero board was produced on the factory’s new continuous press system – part of a £95m expansion and reinvestment process.

The Duke, who also has the title of the Earl of Inverness, undertook a tour of the new mill, accompanied by Norbord’s Jerry Jones, general manager, Mark Reilly, production manager and Steve McTaggart, technical manager, who talked through the production process and the significance of the expansion.

The Duke of York also took time to speak to apprentices about their on-the-job training as part of Norbord’s apprenticeship programme, within which there are various specialisms – electrical, mechanical and technical manufacturing. To commemorate the Duke’s visit and mark the one-year anniversary of Norbord’s new Inverness mill he unveiled a plaque made of OSB, saying: “It’s a privilege to be able to see how manufacturing is growing and becoming more important in this part of the world.”
