NEW YORK – In a challenge brought by James Hardie Building Products, the National Advertising Division (NAD) of BBB National Programs determined that Louisiana-Pacific Corporation (LP) provided a reasonable basis for the claim that “LP®BuilderSeries®Lap Siding is lighter than fiber cement, allowing you to carry more boards with less effort.” However, NAD recommended certain quantified and unquantified superiority claims about its SmartSide, SmartSide ExpertFinish, and BuilderSeries engineered wood products compared to fiber cement products be modified or discontinued. …James Hardie challenged certain quantified installation claims made by LP that touted a precise comparative installation advantage of LP-engineered wood products over fiber cement products including, for example, that “Overall, LP®SmartSide®products installed 30% faster than fiber cement.” NAD determined that the studies did not reliably support such precise quantified results.
