Jan 13, 2010. /Lesprom Network/. Weyerhaeuser has developed a new lumber product for a range of building applications - Pro Series™ Lumber. Weyerhaeuser's proprietary technology and quality control checks remove boards that have a greater tendency to eventually crook, twist or bow. The result is labor and material cost savings in the lumberyard and on the jobsite from reduced need to cull through piles of boards, the company said in a press release received by Lesprom Network. The product carries a "Green Approved" rating by the National Association of Home Builders (NAHB) Research Center for use under the National Green Building Standard™. "The quality of lumber that dealers stock and builders use can help support their business success," says Rob Taylor, Vice President of Lumber Technologies for Weyerhaeuser. "Starting with the trees in the forest and continuing throughout the manufacturing process, we utilize proprietary technologies to eliminate several of the hassles faced with lower quality lumber, creating more value for those customers who choose Pro Series lumber." Weyerhaeuser Pro Series lumber is part of a full line of high-quality lumber including iLevel Framer Series™ lumber and iLevel Machine-Stress-Rated Lumber and Machine-Evaluated Lumber.
