The combination of our commercial, operational, and innovation capabilities allows us to accelerate our long-term enterprise growth strategy with a clear line of sight to meaningful synergies and increased cash flow generation. We look forward to welcoming the talented Masonite team to Owens Corning and working with them to deliver enhanced value to customers and shareholders.”

This agreement brings together two storied companies with a common focus on innovation and making life better at home for the people who use our products every day. As we begin our next chapter after nearly 100 years in business, I am looking forward to Masonite joining the Owens Corning team.”
