Sustainability
Everything old is new again. Working with R. Titter Roofing and White Horse Village, 45,000 pounds of discarded PVC vinyl siding that once would have been landfill-bound has been reclaimed and recycled in a CertainTeed sustainability initiative. At least 140,000 square feet of tear-offs and scraps were crushed, baled, and repurposed into raw material for new siding and other vinyl products.
