Mass timber is transforming how America builds—but supply hasn’t kept pace with demand. A gap in domestic manufacturing has slowed widespread adoption, leaving many developers with few options beyond overseas suppliers or traditional steel and concrete. Through strategic support from the USDA Forest Service Wood Innovations Program, the Forest Service is helping close that gap—boosting U.S. capacity, strengthening rural economies and growing new markets for American wood. One partner answering the call is SmartLam North America. Mass timber products like cross-laminated timber (CLT) and glued laminated timber (glulam) offer a carbon-storing, renewable alternative to conventional building materials. But even as the benefits are clear—strength, fire resistance, design flexibility—developers have faced supply constraints. Limited domestic production has slowed construction timelines, raised costs and stifled innovation.
