Staybull salvages landfill-bound wood strips to manufacture its eco-friendly wide plank flooring. Installers can lay the edge-glued planks over concrete without underlayment, Staybull says. Recycled from more than 20 species of hardwoods, the flooring is free of volatile chemicals and 100% biodegradable, says the firm. The planks are 3/4-inch thick, have a standard 5-inch face width, and come in lengths of 1 foot to 7 feet. 888.525.5966. www.staybullflooring.com.
