Warner opts for floating floors whenever he specifies radiant heating. Synergy strand bamboo flooring from Teragren is a favorite of his. The manufacturer fuses bamboo fibers with an environmentally safe adhesive under extreme pressure. The high-density sheets, which the company claims are 154 percent harder than red oak, are then milled into planks measuring 3¾ inches wide by 24, 36, 48, and 72 inches long.
