Stratum is a mash-up of Smith & Fong’s Plyboo bamboo plywood sandwiched between two sheets of Richlite’s FSC-certified and post-consumer-waste, paper-based surfacing material. Because it weighs 30 percent less than Richlite’s standard product, it’s easier to cut, fabricate, and install. Slabs measure 48 inches wide, 96 inches long, and 1 inch thick. The product is stable with up to an 18-inch overhang, the company says. Richlite, 888.383.5533; richlite.com.
