Architects pick Parklex for its durability and versatility; Bloomberg is no exception. “We were able to run it directly from inside to outside, creating the effect of a continuous, seamless plane,” she says, referring to the firm project shown. “It's not affected by UV rays, as wood is, and its rich, dense color won't fade over time.” Made from high-density Kraft paper impregnated with resin, Parklex's surface is always 100 percent natural wood. It comes in standard 4-by-8-foot sheets. Finland Color Plywood Corp., 310.396.9991; www.fincolorply.com.
