You can't gauge the truth of an opinion by the frequency of its repetition. Exhibit A: Builders' opinions concerning energy, insulation, heating, and cooling. A fair percentage of these beliefs — derived in part from product marketing, obsolete recommendations from "experts," and oft-repeated tales heard at lumberyards — prove upon examination to be half-truths or outright misconceptions.

You can build efficiently with sustainable products, and many pros do, but reusing building materials salvaged from old structures is yet another way to help Mother Earth. The concept is simple: The tons of usable materials that already exist in commercial and residential applications can be carefully deconstructed, cleaned up, and reused in new buildings. More
