In addition to interior flooring, bamboo apparently is good for outdoors, too. BamDeck is an 8-foot-long bamboo deck board that its manufacturer says is comparable to ipe. Dense, strong, and durable, it’s also rapidly renewable, the company adds. Free of urea-formaldehyde glues, the boards assemble with a groove-and-groove hidden fastening system.
