Walkerton, Indiana, USA

Owens Corning, operating at the Masonite plant in Walkerton, announced plans to close its Walkerton facility, which will result in the layoff of more than 120 workers. The closure is described as a recent announcement and is presented as upcoming/planned rather than already completed. The article contrasts this reduction with a nearby Polygon Composites Technology expansion that will add 35 jobs, framing Owens Corning's cuts as a significant local economic blow. No specific timetable or exact date for the layoffs was provided, nor were affected departments named. The report situates the planned job losses within broader local economic developments and community impact.
