Closet hanging rods now include fluorescent lights (Outwater); and there are prefabricated plastic grid attic flooring panels. The Attic Dek product fits through tight attic entries and is ready to install. (Each panel installs with five screws.) And there's a new countertop material from Samsung called Staron. I have to find out more about that. (I'm researching materials for the countertops in the new house.)
I recently read about the new decking materials in an old issue of Fine Homebuilding. Those decks are hot to walk on! And there's a stainproof grout from TrafficMaster.
