Portland’s World Forestry Center has a new exhibit about cross-laminated timber and other newer forms of mass timber, showing now through next summer. The exhibit, called The Future of Tall, tells of the strength, versatility, construction and installation of mass timber products, which are increasingly being used to build multi-story buildings that are cost-competitive, carbon-efficient, sustainable, and reliable. The Future of Tall is on display in the museum’s first-floor Special Exhibits Gallery. It incorporates visual display panels, videos and hands-on pieces. There also is a 13-foot mass timber bench that was formerly displayed at the Portland Art Museum.
